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.

How to Get Your HVAC System Ready For Colder Weather

Friday, September 12th, 2014

It may seem early to talk about readying your HVAC system for fall and winter, especially when your air conditioning may still be running, but in a few short weeks our temperatures will be significantly cooler. Preparing your HVAC system for winter now can get you ahead of potential problems without disrupting your household. Since 1952, Purl’s Sheet Metal & Air Conditioning has helped multiple customers prep their HVAC systems for the coming season, and we can help you, too.

Suggestion 1: Make Needed Repairs

Did you glide into this year’s cooling season without making needed repairs to your heating, or are you ignoring a current repair need for your AC? Such problems rarely go away, and they usually tend to get worse. Take advantage of the upcoming comfortable fall weather and get these issues inspected and repaired.

Suggestion 2: Schedule Maintenance

The two best times of year to schedule maintenance are spring and fall, because you can get ahead of the coming season. Maintenance helps prevent repairs, increases energy efficiency and helps extend the life of your HVAC unit. Purl’s Sheet Metal and Air Conditioning includes the following in HVAC maintenance appointment:

Benefits of a Packaged Unit

Friday, September 5th, 2014

If you’re in the market for a new air conditioning system, there are many efficient options available, and a technician can help you find the right choice for you depending on your home and lifestyle. Here at Purl’s Sheet Metal & Air Conditioning, we want to help you learn about the different types of air conditioning systems so you can decide which one is right for your home. In this guide, we will discuss the benefits of packaged air conditioning systems, an alternative to the traditional split-system air conditioner.

There are two types of HVAC systems that are currently used.   Split systems have components separated with the condensing unit outside the home and the furnace and evaporative coil inside the home, attic, or possibly the garage.  A packaged unit has all the components packaged together, and it is typically mounted outside on the roof or on the ground.

Space

While split-system air conditioners are the most common systems found in homes, some unique home designs do not have the space for installation of an indoor unit. In this case, a packaged unit is often the best option. Because your packaged unit will be connected directly to the ductwork of your home, there is no need for indoor installation. Furthermore, the cabinet may be located on the rooftop, saving space outdoors as well.

Accessibility

Because all of the parts of the system are located in a single cabinet, packaged systems are easily accessible. If you need repairs or if you schedule maintenance, a technician can access your system without moving back and forth between units, as every part is in one location. And because a packaged unit is often located on the rooftop, the technician stays out of your way, so your daily life can continue as usual while you wait for repairs or maintenance to be completed.

Packaged units are just one of the options for air conditioning in Fresno available from Purl’s Sheet Metal & Air Conditioning. Call us today to talk to an expert about the best option for your home.

3 Common Problems with the Condenser Unit

Friday, August 22nd, 2014

Recurrent repair needs are a strong sign that it may be time to consider a new air conditioning installation. Sometimes various problems can occur, or you may deal with one part of your system breaking over and over again. Today we’re going to discuss common problems with your condenser unit and how they can affect your system. Purl’s Sheet Metal & Air Conditioning has trained experts for both repair and installation, so if it’s time to repair or replace, call the technicians you can trust.

What Is the Condenser Unit?

The condenser unit resides in the outdoor cabinet of your air conditioning system. The condenser is comprised of the condenser coils and condenser fan. The main job of the condenser unit is to release the heat from the refrigerant after it’s pressurized in the compressor. The condenser is the middle part of the refrigerant cycle, and when there are problems with the condenser, it can cause system-wide imbalances.

Common Problems with Condenser Unit

There are several common problems that can occur with condenser units:

Refrigerant Leaks

The refrigerant passes through the narrow tubing of the condenser coils, releasing heat as it makes its way toward the indoor evaporator coils. Leaks can develop in the coils, throwing off the delicate balance of the refrigerant. The refrigerant facilitates the transfer of heat in your system, so if the level is reduced due to a leak, the entire heat release/cooling process can malfunction. Problems that can occur from low refrigerant are warm air blowing, icing and compressor issues. Leaks need to be repaired in order to restore proper functioning.

Dirty Coils

It is natural for the condenser coils to attract dust and dirt. However, if the dust and dirt aren’t cleaned from the coils at least once a year, these particles can develop a layer that will act as insulation on the coils. This inhibits the heat release of the refrigerant, and can create problems with the entire cooling process in your system.

Condenser Fan Issues

The fan on your outside unit is known as the condenser fan. This fan helps remove the heat released from the condenser coils and blows it outside; it also helps with airflow. Different problems can emerge with a fan, such as a worn fan belt, motor issues and problems with wiring. All can affect how a fan operates, which can have a direct effect on the heat release process.

If you see recurring problems with your condenser unit, it may be time to consider a new air conditioning system. Call Purl’s Sheet Metal & Air Conditioning today and schedule an air conditioning installation in Fresno with one of our installation experts.

Air Conditioning Upgrades That Help with Energy Efficiency

Thursday, July 31st, 2014

Achieving better energy efficiency in your home is one of the best ways to alleviate high utility bills and reduce the strain on your household appliances. Since a large amount of your electrical budget during the summer goes toward operating your air conditioning system, it is important to focus on ways that you can maximize its efficiency.

One way to increase the energy efficiency of your air conditioning is to invest in upgrades that will make the system draw less power but without sacrificing your comfort.

Here are a few suggestions from Purl’s Sheet Metal & Air Conditioning for upgrades that can lower the energy your air conditioner uses while working its best to keep you cool.

An Upgraded Thermostat

Thermostats have a larger effect on AC efficiency than you probably realize. Older manual thermostat models are often imprecise and inaccurate, that means you will often set them to energy-draining temperatures without realizing it. The current crop of digital programmable thermostats not only increase precision, but they allow you to control the AC when you are not at home. You no longer have to waste power running the air conditioner all day so you can come home in the afternoon to a cool house: instead, you program the AC to turn on a half-hour before you come back.

A Replacement Condensing Unit

If your AC seems to be losing more and more efficiency with the years, you can have the outdoor condensing unit replaced with a new one, instead of replacing the entire air conditioning system. The new condenser will restore the efficiency of the system, and may even make it better than before.

Install a Zone Control System

This upgrade is done to your ventilation system. Technicians fit dampers inside the ductwork that control the flow of air to different parts (“zones”) of the house, and then connect the dampers to individual thermostats. This allows you to shut off cooling to parts of the house that do not require it, such as empty guest rooms. With zone control, you no longer have to expend power cooling down the whole home when only a few locations need it.

Call Purl’s Sheet Metal & Air Conditioning and talk to one of our NATE-certified and EPA-certified technicians for more ideas on how you can increase the energy savings from your AC. We have served Fresno with air conditioning services since 1952, and we can help you get the most from cooling system.

Can I Do Maintenance During the Summer?

Friday, July 25th, 2014

Many homeowners seek air conditioning maintenance at some time around the beginning of spring. Air conditioning maintenance is a valuable service that can improve the performance, efficiency and overall well-being of your air conditioning system. This makes spring seem like the ideal time to schedule service as you can protect your AC for the rest of the cooling season.

However, summer can also be the perfect time to call for air conditioning maintenance. In the summertime in Fresno, your air conditioner is at a high risk of sudden failure, which may be prevented with a maintenance visit. There’s still plenty of time left in the season, so here are a few of the reasons you should schedule air conditioning maintenance today!

Reduce the Chances of Future Repairs

During the summer, your air conditioner runs for long periods of time and works very hard to keep you cool. This may mean, however, that your system begins to develop wear and tear which may seriously damage your system. If your air conditioner receives regular maintenance, you may be able to catch repair needs early on to prevent further damage to your system. During maintenance, a technician performs a full inspection of your AC. If any damaged part of your air conditioning system threatens its well-being, your technician will let you know so that you can schedule repairs early on.

Improve Performance

Air conditioning maintenance also improves the performance of your air conditioner. Low refrigerant levels, dirty parts, or a frozen evaporator coil may all affect the cooling ability of your air conditioner. With maintenance, a technician checks refrigerant levels and cleans the coils so that your AC will continue to cool your home as it should.

Restore Efficiency

When your AC has to work harder due to dirt and debris, a frozen coil, low refrigerant levels, or damage to the system, efficiency often suffers. Air conditioners that receive regular maintenance often maintain a high percentage of efficiency over time, so your bills are likely to be lower than they were before maintenance.

To schedule certified maintenance for your air conditioning in Fresno, call Purl’s Sheet Metal & Air Conditioning today!

What Do Strange Noises from My Water Heater Mean?

Friday, July 18th, 2014

Strange noises coming from any powered appliance is often a sign of trouble, and your water heater is no exception. When an unexpected sound starts to interrupt the standard operation of a water heater, you should call for professional technicians to look into the issue and see what needs to be done. Ignoring the problem puts you at risk of losing your hot water supply when the water heater breaks down.

Here are some of the more common noises that you may hear from a malfunctioning water heater. Please don’t try to do any close diagnosis yourself: call up a water heater repair service and describe the situation, and then let the professional technicians handle it from there.

Purl’s Sheet Metal & Air Conditioning is on call 7 days a week to handle repairs for water heaters in Fresno. You can put your trust in our more than 60 years of quality service to the Central Valley.

Some Water Heater Warning Noises and What They May Mean

  • Popping and banging sounds: Although these noises can be startling, they may simply indicate that you have the water pressure set too high. If that’s not the case, then the high pressure is coming from another source, such as the water overheating, and you will need to call for repairs from a technician.
  • Rumbling: This often indicates that you have excessive levels of sediment at the bottom of the tank. Sediment gathers from particles in the incoming water (particularly if you have hard water), and unless the tank is regularly flushed, the sediment layer will decrease the volume in the tank and create that rumbling sound. Call for technicians to flush out the tank, which should take care of the problem. Another possibility is that a broken dip tube is causing the incoming cold water to mix with the hot water at the top of the tank. Technicians can replace the broken dip tube.
  • Hissing and whistling: These are worrisome sounds, and for good reason: they indicate extreme high water pressure in the heater that could pose a danger. Call for a repair person immediately.
  • Sound of constantly running water: This is often an issue with the pressure relief valve, which is designed to prevent spikes in water pressure by occasionally leaking out water. But if the relief valve breaks, it will start leaking water regularly and create this sound of constant running water. You will need professionals to replace the valve.

Sometimes, an odd sound from a water heater is normal, but you do not want to take any chances. Always call for professional repairs if you notice strange behavior from your water heater. At Purl’s Sheet Metal & Air Conditioning, we offer full service for water heaters in Fresno, CA that includes repairs, installation, and maintenance, and we can handle whatever ails your water heater.

How to Save Money on Air Conditioning During a Heat Wave

Friday, July 11th, 2014

When the summer heat strikes in Fresno, it can slam down on us like an anvil. You need a sturdy and reliable air conditioning system to help you through the long heat. And just as important, you need to have a reliable HVAC service company to help with maintenance and repairs to make sure your AC keeps you cool all the way through the summer.

Purl’s Sheet Metal & Air Conditioning has served the Central Valley since 1952, we have the experience necessary to help you get the most efficient and effective cooling from your air conditioning system.

Of course, keeping the air conditioner working during the heaviest heat can be costly. However, there are ways to keep those costs under control; here are some tips for how to save money during the summer heat waves.

Don’t overwork the AC

It’s tempting to pull the thermostat down to its lowest possible setting when the heat soars. However, this is not only expensive (it keeps the compressor running almost constantly) but it will put tremendous stress on the components that risks a breakdown. You should not set your thermostat lower than 72°F, which is a comfortable temperature that will keep your bills in check and your AC from overworking.

Shut off all non-essential heat-producing appliances

One of the best ways to reduce air conditioning use during heat waves is to lower the amount of heat your air conditioner must combat. If you shut off appliances that generate extra heat during the day time, you can often reduce your air conditioner use by 10% or more. Avoid cooking during the day with stoves and ovens. Do not use indoor laundry facilities. If possible, avoid taking daytime showers, which produce high levels of moisture that makes the heat feel worse.

Schedule maintenance for your air conditioning

This is planning ahead: you should always have a maintenance visit from an HVAC technician once a year to make sure that your air conditioning system is working at its best and provide necessary adjustments, tunings, and cleanings. This will not only make sure that your air conditioner is not costing you extra money to run, but it will also catch potential repair issues that might turn into major repair problems during the stresses of a heat wave. Maintenance is the best preparation you can have for a long summer.

Get started saving money and preparing for the heaviest heat the summer can offer with a call to Purl’s Sheet Metal & Air Conditioning. Sign up for our Ultimate Service Agreement, which includes two seasonal tune-ups for your air conditioner and your heater from NATE-certified technicians, plus preferred customer states and discounts on repairs and upgrades. We are here to help you save money on air conditioning in Fresno, CA all year long.

What Are My Water Heater Options?

Old water heater

Water heater replacement job in Fresno

Even though it is summer and our daytime temperatures are around 100 degrees, running out of hot water because of a water heater malfunction is still something no one wants to deal with. If you’ve had to do a lot of recent repairs on your water heater just to keep it operating, it may be time to consider the purchase of a new one. The good news is that there are several options available for homeowners when it comes to purchasing new water heaters in Fresno, so replacing an old water heater may actually be better for your home. And remember: it’s best to have a professional company like Purl’s Sheet Metal & Air Conditioning install your water heater to ensure that it goes in correctly.

Types of Water Heater Upgrades Available

There are several types of water heaters currently on the market:

Conventional Water Heaters

Conventional water heaters have been the norm for many years, and still remain a very popular choice among homeowners. Conventional water heaters are cylindrical-shaped storage tanks that heat and hold water for usage in your home. These types of water heaters come in different capacity sizes to accommodate a range of properties, holding anywhere from 20 to 80 gallons of water at a time. Different fuel types can heat the water, including electricity, natural gas and oil. While great strides have been made to increase energy efficiency with this type of water heater, it still may not be as energy efficient as others on the market, and the average lifespan is 10 to 12 years.

Tankless water heater

Upgraded to a tankless water heater

Tankless Water Heaters

Tankless water heaters have become very popular over the last few years, and for some very good reasons. One of the main appeals of tankless water heaters is that they heat water on demand; this means there is an endless supply of hot water for your property. Secondly, as the name indicates, there is no need for a storage tank to hold the hot water. With a tankless system, the hot water is heated directly when the hot water tap is turned on; the cold water is instantly heated by a heating element that uses either natural gas or electricity. This feature makes tankless hot water heaters very energy efficient.

One of the main drawbacks to tankless water heaters is that the flow rate of the water is typically lower than that of a conventional water heater. A second drawback can be the initial cost, but on average, tankless water heaters last longer than conventional ones and they can save money on a monthly basis through utility bills.

Heat Pump Water Heaters

Heat pump technology can be used for a wide range of household appliances, which is one of the reasons we like them so much here at Purl’s Sheet Metal & Air Conditioning. Using the same type of process for heating and cooling your home, a heat pump water heater removes the heat from around its space to heat the water in your home. Storage tanks are used with this system, and can store up to 50 gallons of heated water. Heat pump water heaters are recommended for geographic areas that don’t get colder than 40 degrees, and they require at least 1,000 cubic feet of surrounding air space, (approximately a 10-foot x 10-foot x 10-foot room) for installation.

Problems Caused by Dirty Air Filters

Friday, June 27th, 2014

air filters, old and newEvery air conditioner has an air filer, deigned to catch particles of dirt and dust and keep them from moving through the system. Air filters need to be changed periodically (though some models have reusable filters that can be washed instead of being replaced) or else they can cause a considerable number of problems. Here in Fresno, air conditioning services can usually treat the problems cause by dirty air filters, but the more you know about the issue, the better you can prevent such problems from starting in the first place. Call us today if you need your air filter replaced in Fresno.

Dirty air filters tend to clog the flow of air through the system, which means your air conditioner needs to work harder in order to do its job. Not only does this increase strain on the entire system (raising the risk of repairs), but it forces your AC unit to expend more energy, which results in higher monthly bills. In addition, the excess dirt blown through the system will spread throughout your household via the air ducts. If you have sensitive family members, such as the elderly or those suffering from asthma, this can constitute a health risk, and even in healthier family members, the excess dust can result in a scratchy, irritated throat and lungs.

On top of that, the excess dust can coat the inside components of your air conditioning system itself. This can create friction in moving parts, increasing the overall wear and tear and raising the chances of a more serious breakdown in the future. It can also create ice on the evaporator coils, clog lines and other key components, and cause no end of slow, long-term damage over time.

You can reduce the risk of problems caused by dirty air filters by having them changed regularly, ideally as part of a larger maintenance session from the experts at Purl’s Sheet Metal & Air Conditioning. We have the skills you need to do the job right, and we can help you stop a number of issues before they start.

Here in Fresno, air conditioning systems are an absolute necessity during the heat of summer. Give us a call today and let us make sure it’s ready when you need it!
