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.

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.

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

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.

Leading the Way with Independence Days!

Thursday, July 3rd, 2014

The term “Fourth of July” is the popular name for the U.S. federal holiday officially known as Independence Day. It isn’t surprising that we would come up with a different name from the official one, since “Independence Day” is one of the most common holiday names across the globe. Most of the nations in existence today won their independence from another power, whether through wars, treaties, or long transitions.

What might surprise many people is how old U.S. Independence Day actually is compared to the similar holidays of other nations. Although the U.S. is still considered a young nation, it was one of the first to make a full break for its colonial master with a new constitution. Most countries that celebrate a national Independence Day are commemorating events that occurred in the second half of the 20th century, when many older empires at last relinquished control over their colonies.

How substantial is the difference in time for the U.S.A. and the rest of the world? U.S. Independence Day celebrates the signing of the Declaration of Independence from the Kingdom of Great Britain in 1776, making our country unusual in that almost no existing nations celebrate an independence event from the eighteenth century.

In terms of age, there is only a tiny handful current countries that celebrate an independence day that occurred earlier than the United States. Switzerland celebrates its independence from the Holy Roman Empire of the Germans in 1291 with “Swiss National Day,” held every August 1—although this only gained status as a national holiday in 1994. Sweden Celebrates “National Day of Sweden” to commemorate events in 1523 and the election of King Gustav I during the War of Liberation against Christian II of Denmark and Norway. Romania comes almost a hundred years after U.S. Independence, with its 1877 freedom from Turkish rule.

The most recent Independence Days to come into existence are for Montenegro, which gained independence from Serbia in 2006 and celebrates the day on May 21, and South Sudan, which gained independence from Sudan in 2011 and celebrates the day only a day after the U.S., on July 5.

Does anyone else celebrate a literal “Fourth of July,” an Independence Day that also falls on the fourth day of the seventh month? Yes: Abkhazia, a small Central Asian country that declared its independence from the Republic of Georgia in 1999 (although not all countries recognize it). Coming a day (like South Sudan) on July 5 is the independence of the small Atlantic island nation of Cape Verde, which became free from Portugal through signed agreement in 1975.

Everyone at Purl’s Sheet Metal & Air Conditioning hopes you and your family enjoy a vibrant Independence Day/Fourth of July this year!
