Almost any modern home can benefit from air cleaners of some type. Indoor air quality is often poor because homes are built today to seal out the heat in summer and seal it in during winter—and that means not much fresh air circulation.
What type of air cleaner is best for a home? There are plenty of options, and our IAQ experts at Purls Sheet Metal and Air Conditioning are happy to help you find the best. In most cases, improving air quality starts with putting in filters and then finding what other devices might help. Filters are almost always a good idea…
…except when the wrong type of filter goes in. When it comes to high-efficiency filters, such as the HEPA filter, you can have too much of a good thing. Too strong a filter can damage your HVAC system.
One of the more common problems that affects residential air conditioning systems is refrigerant leaks. An AC is designed to work with a specific amount of refrigerant, known as the system’s charge. The AC doesn’t use up the refrigerant as it runs, so under ideal circumstances, the refrigerant will remain at the same charge for the life of the system.
We take great pride in our staff here at Purl’s, and right now we’re all very proud of our own Alicia Rodriguez, who graduated from Fresno State this May. Alicia first started working at Purl’s in 2014 in the service department and is now an office assistant who enjoys working directly with our customers and helping them to enjoy the best comfort for their homes. Congratulations, Alicia!
During a hot summer here in the Central Valley, you’ll want your air conditioning system to work at its best. This means reliable, even cooling around the rooms, and utility bills that don’t rise too high. Standard malfunctions can threaten your AC’s performance, but they aren’t the only danger to the well-working of your air conditioning system. Many people don’t realize that poor ductwork is often a serious problem for cooling systems.
Unlike heating and air conditioning systems, there’s no “season” for water heaters. The average water heater does more work during winter, but it still operates almost every day of the year to meet a household’s needs.
The condenser, or condenser unit, is one of the vital parts of a home’s air conditioning system. When HVAC technicians refer to the condenser, they’re talking about the entire outdoor unit of a split system air conditioner, the type most people use for home comfort. The condenser houses the compressor, which places the refrigerant under pressure so it will circulate through the system, condenser coils where heat is released to the outdoors to cool down the refrigerant, and a blower fan to draw air across the condenser coils and then exhaust the heat out of the unit.
If you recently glanced at weather reports from around the country, you’ll have noticed how unpredictable April can be: snowstorms striking Vermont, Minnesota, Michigan, and Wisconsin. Central California never experiences anything so extreme (except up in the mountains), but April is still no time to risk having your heating system fail. So even though the calendar says it’s spring, don’t let that stop you from taking action with your furnace if it’s putting your comfort in jeopardy. 
It’s been raining this week and last week in Fresno, CA. This rainfall is very welcome, since we’ve been going through a drought and rain brings relief for farmers. But there’s a downside—and we don’t mean having an outdoor touch football game being rained out. Spring rains cause the pollen count to rise, and this can be terrible for allergies. Watery eyes, runny nose, sneezing, and all types of allergy irritations occur because there’s too much pollen drifting in the air.
If you look at the home page of our website, you’ll see right under our name at the top of the page is our contractor’s license number: 463756. We have it displayed there because the license is what sets us apart from an amateur contractor. Each state has different requirements for licensing and regulation. Here in California, holding a license means a contractor has the necessary insurance and bonding required locally.
