"You want an honest HVAC company? Look no further. Dave and his crew were the only people who would come and fix our boiler wiring- everyone else was either too busy or refused to deal with a smart thermostat. They came when they said they would, did the work, and charged exactly what I was quoted beforehand. So, when our 20 year old boiler stopped lighting, I called again. And again, he showed up when he said he would, explained what was going on, and charged an exceptionally reasonable price to fix it."

Heating and Air Conditioning FAQs, answered by experts

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

An HVAC unit, like a furnace, air conditioner, or heat pump, produces warm or hot air. The air ducts serve as the passages to help heat or cool air from the HVAC unit flow through the home. Air ducts are just one part of the overall HVAC system.
