What Does the AFUE Rating on a Furnace Mean for My Heating?

Friday, November 14th, 2014

The energy efficiency of the furnace that keeps your house warm is one of the most important things to know about it. You can use it to estimate how much a furnace will cost to run, and it also serves as an early warning of repair issues should the furnace start to create higher heating bills than normal.

Central furnaces, whether gas or electric, have their efficiency measured in AFUE, an acronym for “Annual Fuel Utilization Efficiency.” Understanding how AFUE is measured will help you better understand your furnace. It will also caution you about when to call for repairs or schedule a replacement for the furnace. When you need expert service for your furnace, call on a highly-trained team with a long history in the HVAC industry in Fresno with heating: Purl’s Sheet Metal & Air Conditioning.

What the AFUE Rating Means

Annual Fuel Utilization Efficiency is expressed as a percentage. This percentage is the amount of energy put into the furnace that it converts into heating power, as measured over a year. The larger the percentage, the more fuel is turned into heat and the less is wasted as exhaust. For example, if a gas furnace produces on average 90 BTUs for each 100 units of natural gas that it burns, then it has an AFUE of 90%.

The Federal Trade Commission requires that manufacturers of furnaces include AFUE ratings on all new units. A non-condensing furnace must have a minimum of 78% AFUE (unless designed for a mobile home). The Department of Energy has new requirements for furnaces that are set to go into effect on January 1, 2015: all weatherized gas furnaces must have 81% AFUE after this date.

However, many furnaces score much higher AFUE ratings than this. High-efficiency furnaces often rank above 90% AFUE. Electrical furnaces are also extremely fuel efficient, but electricity is usually a more costly energy source. If you are planning to have a new furnace installed, you will need assistance from heating and cooling experts to find the right balance of efficiency and cost to fit your home and budget.

As long as your furnace receives regular annual maintenance from skilled technicians, it should keep 95% of its efficiency for most of its service life. If you notice a spike in your heating bills, it can mean your furnace needs repairs or it has reached a point where it is losing efficiency due to age. In either case, call for furnace professionals to look into the issue and see what needs to be done.

Purl’s Sheet Metal & Air Conditioning has many decades with residential furnaces in Fresno. Whether you need new installation, maintenance, or repairs to protect your home’s heating, you can count on our services seven days a week.

What’s at Risk if I Try to Install a Furnace on My Own?

Friday, November 7th, 2014

We understand that many people in the Central Valley have strong “do-it-yourself” drives when it comes to home improvements and repairs. However, if the home improvement that you need to undertake is installing a new gas furnace, you absolutely do not want to tackle the job on your own, or even hand it over to a team of amateurs. There are some very good reasons that furnace installation is a job for professionals and professionals only.

It’s easy to locate experts in home heating in Fresno who can install a new furnace for your home: call Purl’s Sheet Metal & Air Conditioning today and speak to one of our team, and we will help schedule a new installation that will give your household many years of warmth.

The Risks Involved In DIY Furnace Installation

The most important reason you should leave furnace installation to the professionals is that attempting the job yourself can be flat-out dangerous. Gas-powered furnaces connect to the gas main that enters your house, and trying to work on this line can expose you to toxic and combustible gases. In many jurisdictions, it is illegal for anyone except a licensed professional to work on any appliance connected to the gas main. Most furnace manufacturers also require that only professionals handle the installation job. Don’t take any risks of fires or exposing your family to carbon monoxide.

Aside from the potential physical dangers of DIY furnace installation, the necessary work is simply too precise and requires too much special equipment for anyone to handle it correctly unless they have years of training and access to high-end tools. Custom-cutting for the gas pipes alone is a technical skill that goes beyond do-it-yourself tactics. If you are planning to install a higher efficiency furnace for your home, modifications to the ductwork are often necessary, and this needs professionals to handle; trying this on your own could deliver you a furnace that doesn’t vent correctly or fails to distribute air to the rooms.

So leave aside any ambitions about installing a furnace yourself. The risks are too high. Professionals will handle the installation correctly so that the new gas furnace works as it should and will continue to do so for many years. And they will do the job in only a fraction of the time it might take amateurs.

Purl’s Sheet Metal & Air Conditioning has served the community since 1952. We are headquartered in Madera, CA, which Forbes recently listed as one of America’s Booming Small Cities for 2014, with a job growth of 25% over the last fourteen years and a personal income growth of 22%. We are proud to be part of Madera’s continuing expansion, as well as providing services for excellent cooling and heating to Fresno and other surrounding areas.

How a New Thermostat Will Help Your Heating

Friday, October 31st, 2014

It’s easy to take for granted the thermostat that runs the heating system in your home. However, a thermostat has a crucial part to play in the operation of a heater, and should it malfunction, it will mean a heating system that won’t turn on, won’t turn off, or provides uncomfortably high or low temperatures.

Even if your home’s thermostat is in excellent working condition, you may benefit from upgrading it to a more advanced unit. When you call home heating and cooling specialists to handle thermostat purchase and installation, you’ll receive a quality job that will live up to your expectations. Poor installation of thermostats can result in heating and cooling systems that run inefficiently—or may not run at all.

The NATE-certified technicians at Purl’s Sheet Metal & Air Conditioning provide quality installation of thermostats to help achieve better residential heating. If you have an older model thermostat in your home, contact us today to find out more about options for upgrading.

Why a new thermostat can mean better heating

Although manual thermostat models are effective at controlling temperatures in a home, they lack the precision of newer digital models. The difference between a manual model and a standard digital model thermostat is small, however: a matter of a degree or two when it comes to temperature settings.

The big difference is when you upgrade from either of these two thermostat types to a digital programmable model. A programmable thermostat grants you control over your heating system even when you are not home. You can set the thermostat to turn the heater on a half hour before you return home, which means you can come in the door after a day at work and straight into an already warm house—without needing to waste money running the system throughout the day. This means greater comfort without a sacrifice on your heating bills.

There are different levels of complexity for programmable thermostats. Basic models usually have two program slots: one for morning and one for evening. More advanced models can allow different programming for each day of the week, and this will help you enjoy pleasant temperatures and energy-savings without needing to constantly manipulate the thermostat.

One of new innovations in thermostat technology is the Wi-Fi thermostat. These models allow you to control your heating and cooling remotely with a laptop or mobile device, from anywhere you have an Internet connection. This will help you further reduce energy consumption, and you won’t have to worry about accidentally leaving the heater or air conditioner running when you’re away from home.

Call Purl’s Sheet Metal & Air Conditioning if you think your home will benefit from a more up-to-date thermostat. We will help you find the replacement unit that will give you better heating in Fresno, CA as well as increased energy savings.

Is a Heat Pump Effective for Winter Heating?

Friday, October 24th, 2014

When it comes to providing comfort throughout the year, a heat pump is an excellent installation option. Heat pumps work in a manner almost identical to air conditioners: they circulate refrigerant between an indoor and outdoor unit, moving heat from one location and releasing it in the other. When set in “cooling” mode, the heat pump absorbs heat from the indoors and releases it outdoors, the same as an air conditioner. In “heating” mode, a reversing valve in the system switches the direction of heat exchange, and the heat pump absorbs heat from the outdoors and then releases it indoors.

However, this description of the way a heat pump works often prompts the question from homeowners: “If I’m using a heat pump to warm my house during cold weather, how is the heat pump drawing heat from outside?” This causes some people concern about whether a heat pump is an effective option for home heating in Fresno, CA.

We understand where this concern comes from, but for many homes a heat pump is more than sufficient for delivering comfort through a Fresno winter. If you want advice from professionals who can tell you if installing a heat pump is a good option for your house, call at Purl’s Sheet Metal & Air Conditioning.

Here is what to consider when thinking about heat pumps in heating mode: there is always some heat available in the outside air, regardless of how low the temperature is. It becomes more difficult for a heat pump to efficiently remove that heat from the outdoor air during extremely low temperatures; however, the temperature must usually fall below freezing before this problem with inefficient operation starts. The average low temperature in Fresno during the two coldest months of the year is 38°F, still above freezing. In homes with effective insulation, a heat pump can usually handle the winter weather without losing its efficient performance.

You should definitely consult with heating and cooling professionals before you settle on a heat pump for installation. (And you should never attempt to install a heat pump on your own, anyway.) Professionals will help you decide if a heat pump will provide the comfort level necessary, and then size and install it so that it works as it should.

Call Purl’s Sheet Metal & Air Conditioning for heat pump services. We have helped with cooling and heating in Fresno, CA since 1952, and we’re on call 7 days a week for your convenience.

Repairs Your Gas Furnace May Need

Friday, October 17th, 2014

Furnaces are one of the more common ways to provide heat for homes. A properly cared-for furnace can deliver high heating levels and operate for many years with only occasional repair needs. If you have a furnace installed in your home, make sure that you schedule annual maintenance for it during the fall to lower the chance that you will have to call for repairs during the winter.

There is no way that you can avoid all repair needs for a furnace, no matter how well you keep the system maintained. Below are some repairs that a furnace may require during its service life to keep it working efficiently, effectively, and safely. If you notice an issue with your furnace—such as a drop in heating levels or strange sounds coming from the cabinet—call for furnace repair service in Fresno from Purl’s Sheet Metal & Air Conditioning. We have 60 years of experience servicing heating systems in the Central Valley.

Some Common Furnace Repair Needs

Replacing cracked heat exchangers: The heat exchanger is the component of a furnace responsible for transferring heat from the combustion gas to the air from the blower. If a heat exchanger starts to develop corrosion with age, it may lead to cracks and exhaust gas escaping from the furnace. This is a potentially dangerous situation, and a technician will need to replace the exchanger should it happen. Technicians will notice issues with the heat exchanger during a regular maintenance visit and arrange for the repair work to replace it.
Ignition repair: Most modern furnaces no longer use a standing pilot light, but instead ignite the gas jets along the burner using electronic ignition. This ignition can malfunction or fail, which will result in either delayed ignition or the furnace burners not coming on at all. Don’t try to repair this problem on your own: call for professional assistance to repair or replace the electronic ignition.
Blower motor repair: The motor that runs the blower can overheat if it develops too much stress on its mechanical parts due to dust, dirt, or lack of lubrication. An overheated motor will burn out and stop working if it doesn’t receive repair work. If you detect airflow issues or discover that the blower will not turn on at all, call for repair technicians right away.
Recalibrating the thermostat: Sometimes what seems like a furnace malfunction actually comes from a miscalibrated thermostat that is reading temperatures incorrectly and turning the furnace on and off at incorrect times. Skilled technicians will know how to track down the trouble to the source and fix it.

We must emphasize that you should never attempt repairs to a gas furnace on your own because of the potential safety risk. Call on the experienced team at Purl’s Sheet Metal & Air Conditioning for your heating repairs in Fresno, CA. We are on call seven days a week.

3 Repairs for Heating You Need to Take Care of Before Winter

Friday, October 10th, 2014

Before the steady low temperatures of winter arrive, you should know if your heating system has any malfunctions that may impair it or even cause it to break down. The best way to know if you need to schedule repairs is to take the heater for a brief “test run” during a warm day to see if you notice anything wrong. Afterwards, arrange for the heater’s annual maintenance visit from an experienced HVAC service technician.

Below are three common repair issues that heating systems may need before winter starts. You can call Purl’s Sheet Metal & Air Conditioning seven days a week to handle any of these troubles, as well as to sign up for our Ultimate Service Agreement to handle maintenance. We are here for all your needs for HVAC repair in Fresno.

3 Common Heating Repair Issues before Winter

Gas line problems: You don’t want to turn on a gas furnace at the start of winter and discover that the gas isn’t flowing to the burner. If during your test run on a gas furnace you discovered that the burner wouldn’t ignite, even though the pilot light or electronic ignition was working, than you probably have trouble in the gas line. As with any device hooked up to natural gas, you never want to attempt repairs on your own. Only trust to experienced professionals.
Broken ignition/failed pilot light: Everything else in a gas furnace may be operating well, but if the pilot light will not remain on, or the electronic ignition has failed, nothing will happen. Dirt across the burner can cause a pilot light to keep going out, or not come on at all, and electronic igniters can fail for a variety of reasons. Repair technicians can clean off the burner or replace the igniter to restore the furnace’s operation.
Low refrigerant: This is an issue with heat pumps, which use the circulation of refrigerant to provide both cooling and heating throughout the year. The refrigerant in the system will not “get used up” during normal operation, but leaking can cause the level of the refrigerant (its “charge”) to begin to drop, which will affect its heating ability and could also lead to serious damage to its components. Because this affects the cooling ability as well, you shouldn’t ignore a dip in air conditioning power from the heat pump during the end of the warm season, since this decline will carry over to heating mode. Professionals will locate the refrigerant leaks, seal them, and recharge the refrigerant to its proper level.

During a maintenance visit from one of the experienced technicians at Purl’s Sheet Metal & Air Conditioning, you will learn about any repair troubles your heating system has. We will arrange for the repair work to take care of the malfunction so you will have your heating system ready in time for the winter cold. Trust in us for any repairs in Fresno, CA for your HVAC heating system needs.

Signs You Need a Furnace or Heating System Replacement

Friday, October 3rd, 2014

The fall is one of the best times of the year to schedule heater or furnace replacement. The weather is still warm enough that you won’t need the heater running yet, giving you time to arrange for installation and to find out if the new system has any operational problems. You can also take advantage of this slower period for HVAC professionals to schedule the most convenient time for the installation job. You will be all set with your new heating system before the first cold weather arrives.

You should only replace your heater if it’s necessary, however. A few targeted repairs from skilled professionals will often keep a malfunctioning heating system running smoothly for another few years. But you need to pay attention to signs from an aging heater that it is moving past the point where repairs and maintenance will keep it working. If you are unsure about whether you should replace your heater or continue with repairs, call the experts at Purl’s Sheet Metal & Air Conditioning. We have handled heating replacements in Fresno, CA since 1952.

Watch For These Signs It Is Time for Heating System Replacement

Noisy operation: Any strange noise from a heating system, especially a gas-powered heater, needs immediate investigation from skilled technicians to see if it requires repairs. If a heating system constantly makes loud and obtrusive sounds when it runs, then the issue probably runs deeper than what a single repair can handle: the system has worn down to the point that replacing it is the more cost-effective solution.
Numerous repairs: If a heating system receives regular maintenance, it helps increase the life span of the heating unit and reduce future repair costs. Most heaters need the majority of their repairs during the last two years of service, so when the repair bills start to pile up, you need to consider heating replacement as an option. Any repair that would cost half the price of replacing the system is too expensive, and replacement is the better option.
Corrosion: This applies to gas-powered furnaces, the most common type of heating system. The reaction of combustion gas with metal in a furnace will eventually create corrosion, especially if the unit is having trouble venting adequately. When corrosion begins to appear on a furnace, it indicates that age has caught up with it and you need to install a new furnace. Corrosion is potentially hazardous since it can lead to cracks in the heat exchanger and gas leaks, so do not hesitate to call for professionals when you spot this.

Replacing an old heating system is easier than you might think. When you contact Purl’s Sheet Metal & Air Conditioning for heating replacement service in Fresno, CA, you’ll receive the highest quality service from professionals with years in the business. We can handle the work for you, done fast and right the first time.

Heating Guide Should You Repair or Replace Your Heating System?

Friday, September 26th, 2014

Although manufacturers of heating systems build their products to last for many years, a heating system will eventually reach a point in its service life when it can no longer do an efficient or effective job of keeping a home warm. Although regular maintenance and prompt repairs will help a heater endure for as long as it can, a time will come when you will have to make a choice about whether it is worthwhile to continue to repair the system, or to have it replaced with new installation.

You do not need to make the choice on your own, however: heating professionals like the staff at Purl’s Sheet Metal & Air Conditioning are available to help you choose between “repair and replace.” When it comes to heating installation and replacement in Fresno, you can trust in our many decades of experience to guide you toward the best choice for comfort and long-term savings.

When Is Replacement The Best Option?

To get started with answering this question, you need to check the age of system against the manufacturer’s expected lifespan for it. If the heater is at or over the estimated lifespan, then you should already be considering replacing the unit—even if it is currently working well. The system is at the age where it will likely soon begin to decline, and getting a head start on a more efficient new heating system. If the heater is still a few years away from the end of its lifespan estimate, you should keep repairs as an option, but call for a technician to look over the system to give you a better idea.

If you have started to call for repairs on a regular basis for the heater, you will probably save money if you retire the system and replace it with a new one. A good rule of thumb to follow is that if a necessary repair will cost half of what it will cost to replace the heater, you should replace instead of repair.

A rise in your heating bills that will not come down no matter what repairs or maintenance you have done is usually a strong sign that the heater has entered into an irreversible decline. When you call for repairs, the technician will be able to tell you the best route to take.

All of the heating technicians at Purl’s Sheet Metal & Air Conditioning are NATE-certified, and when you call on their services, you will receive the answer you need to find out whether it’s time for repairs or new heating installation and replacement in Fresno, CA.

Ways Faulty Ductwork Can Affect Air Conditioning

Friday, September 19th, 2014

Not all the trouble that can plague an air conditioning system comes from inside the AC cabinets. Often, a faulty thermostat can cause a cooling system to work incorrectly. Another common source of air conditioner problems are faults in the ductwork connected to it, such as air leaks and breaks.

It is often difficult to tell the source of a malfunction in an AC if you are not a trained technician. Don’t attempt to guess at what has gone wrong when your air conditioner starts to lose its cooling ability, generate strange noises, or show other signs of working incorrectly. Call on HVAC experts to look into the problem, locate the source, and fix it.

Purl’s Sheet Metal & Air Conditioning has served the Central Valley since 1952. If your air conditioning system is suffering from problems due to faulty ductwork, you can trust to our team to handle the necessary repairs and duct sealing to restore your cooling.

How Faulty Ductwork Impairs an Air Conditioning System

Well-designed ventilation systems are airtight. This prevents loss of air pressure as the conditioned air from the AC moves toward the vents. Even a small leak along the ductwork can cause a drop in air pressure that will lower the airflow from the vents and lead to a loss of cooling in the rooms.

As an air conditioner loses air pressure because of faulty ducts, it will also start to work harder in order to maintain its target temperature. This places extra strain on the system, which increases the chances of it malfunctioning. The increased stress level on the mechanical components will also make the air conditioning system age faster and possibly need premature replacement.

Breaks along ducts often permit outside contaminants into the ventilation system, and subsequently into the AC. Even if this extra dust and dirt gets caught in the system’s air filter, the filter will rapidly clog up to the point that it will cause a large increase in the strain on the air conditioner. Clogged filters may also lead to ice developing along the indoor evaporator coil.

Call Us for Ductwork Sealing

When you suspect that your air conditioning system is suffering due to leaks in the ductwork, contact Purl’s Sheet Metal & Air Conditioning to schedule AC service in Fresno, CA. All of our technicians are NATE and EPA-certified, and they are on call 7 days a week for your convenience.
