Heating Guide Should You Repair or Replace Your Heating System?

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

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

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:

Check and clean indoor air filter
Check contactor for wear
Check capacitor
Check time delay
Check & clean outdoor condenser coil
Inspect indoor evaporator coil
Inspect evaporator metering device
Check compressor start & run amp draw
Check for proper line & low voltage at A/C
Check all line voltage electrical connections
Check condenser fan motor running amperage
Check and oil outdoor fan motor if applicable
Check suction and liquid line temperature
Verify proper refrigerant charge
Verify indoor & outdoor temperatures
Check A/C temperature split
Inspect indoor blower
Check & clean condensate pan & flush condensate line
Check indoor thermostat for proper operation
Explain any repairs that may be needed

Suggestion 3: Have Your Air Filter Changed

Clogged air filters can cause issues with air flow that can affect your whole system. By changing out the air filter in your HVAC system, you can easily prevent such issues.

Your air conditioning may have a few weeks left to work, but the cool air is coming. Get ahead of the season and get your system ready for colder weather by scheduling your HVAC maintenance or repair in Fresno with Purl’s Sheet Metal and Air Conditioning.

Benefits of a Packaged Unit

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.

The Very First Labor Day Celebration

August 29th, 2014

Labor Day as a federal holiday, held on the first Monday of September, has been with us now for 120 years. President Grover Cleveland signed the law that made Labor Day a national holiday in 1894. Ever since then, the three-day weekend has provided people in the U.S. with the opportunity for vacations, time with their families, shopping trips, and a general celebration of the conclusion of summer and the beginning of fall.

However, there were twelve years of Labor Day observations in the U.S. before it became an official holiday. The first Labor Day celebration took place in 1882 in New York City on September 5. According to the accounts from the time, it had a rough start and almost didn’t happen.

The main event planned for that first Labor Day was a parade along Broadway that was to start at City Hall. However, the parade ran into a bit of a snag early on. The marchers started to line up for the procession around 9 a.m., with a police escort to make sure the event went peacefully. However, the problem of the day wasn’t rowdy members of the parade—it was that nobody had remembered to bring a band!

With people ready to march, but no music to march to, it started to look like no parade would happen at all, and the first Labor Day would have ended up a failure. But just in time, Matthew Maguire of the Central Labor Union—one of the two men who first proposed the celebration—ran across the City Hall lawn to the Grand Marshal of the parade, William McCabe, to inform him that 200 men from the Jeweler’s Union of Newark were crossing the ferry to Manhattan… and they had a band!

At 10 a.m., only an hour late, the band from Newark walked down Broadway playing a number from a popular Gilbert and Sullivan opera. They passed McCabe and the other 700 marchers, who then fell in line behind them. Soon, the spectators joined in, and an estimated 10,000 to 20,000 people marched through Lower Manhattan.

According to the New York Times, “The windows and roofs and even the lamp posts and awning frames were occupied by persons anxious to get a good view of the first parade in New York of workingmen of all trades united in one organization.”

The parade concluded two hours later when the marchers reached Reservoir Park. But the party was only getting started. Until 9 p.m., some 25,000 people celebrated with picnics and speeches and beer kegs. It was an enormous success, and all thanks to the speedy arrival of jewelers carrying band instruments.

If those musicians from Newark hadn’t shown up, perhaps we wouldn’t have the holiday opportunity that we now have every year. However you celebrate your Labor Day, our family at Purl’s Sheet Metal & Air Conditioning wishes your family a happy end of summer.

3 Common Problems with the Condenser Unit

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.

How Do Heat Pumps Cool?

August 15th, 2014

Although the word “heat” is included in the term “heat pump,” this high-performance system does more than keep people warm. While these systems can move heat into a home, they can also move heat outside, allowing cool air to blow into a house through the vents. Heat pumps are actually very effective cooling systems because they work exactly like standard air conditioners, but with one key difference: the reversing valve that allows for dual functions.

Much like any other air conditioning system, a heat pump cools a home using a chemical blend called refrigerant. The system is only called a heat pump because it pumps heat into your home during the heating season and pumps heat out of your home in the cooling season. Refrigerant is responsible for the thermodynamic process that allows for this heat exchange to occur.

When you turn on your heat pump during the cooling season, refrigerant first leaves the compressor as a high-pressure gas and makes its way to the condenser. Here, heat releases into the outdoor air during the condensation process that changes the refrigerant into a liquid. The expansion valve allows the pressure of the liquid to drop. Finally, it flows to the evaporator coil, where the liquid refrigerant evaporates into a gas and absorbs heat in the process. An indoor fan then blows cool air into your home.

The reversing valve is the part that differentiates the heat pump from a standard central air conditioner. When you switch the thermostat to heating mode, refrigerant actually flows in the opposite direction, a process unavailable with most central air conditioning systems. When the thermostat engages the reversing valve, refrigerant flows in the opposite direction. When this happens, refrigerant pulls heat from the outside air and moves the heat indoors.

Heat pumps can be very efficient systems for both heating and cooling. Many heat pumps have high SEERs (Seasonal Energy Efficiency Ratios), and a high HSPF (Heating Seasonal Performance Factor). These rating systems give an indication of a system’s average energy use, so you can save money selecting a more efficient system. If you want help selecting energy-efficient heat pumps in Madera, call the experts at Purl’s Sheet Metal & Air Conditioning today!
