"Sean was great about repairing my disconnected dryer air duct having to go into the crawl space and figure out what was going on. I'm glad he was able to get it done very quickly as well. He also had a very good attitude about doing the work."

"Ray was very responsive and professional since my first contact with him. He came out early the next day to diagnose my broken AC and walked me through the testing stages and explained what he was doing, how it works, and why. He tried several methods to get the system up and running but ultimately, we had to replace the old unit. Since we were in a 100 degree heatwave, Ray was mindful of our situation and came early the next day to install the new unit within an hour. Very fortunate to have a seasoned professional like Ray to help us amidst the heat and Covid. I would highly recommend him to anyone looking for central AC work."

"Very knowledgeable, professional, and great customer service! Penguin, serviced our central AC & Heat and they explained everything to us before performing the work. They also replaced our moldy insulation in our attic. They packed and transported the old moldy insulations, ensuring that the mold does not spread, and they left our house free of any mess. I'd recommend Penguin Heating and Air to anybody in need of AC/Heat service, repair, or installation."

"I highly recommend Top Energy Solutions. During the heat wave my air conditioning system blew out hot air. I expected to wait days for a technician to come out. Leor sent one the next morning. The technician quickly located the problem and fixed it within minutes. Their employees are professional, courteous and very knowledgeable."

"We had our AC system replaced by Jet Air Solutions, and the experience was great from start to finish. They were on time, explained everything clearly, and never tried to sell me on things I didn’t need. The installation was clean, professional, and completed when they said it would be. The house cools so much better now, and we can already tell the new system is much more efficient!!! It’s hard to find contractors who are honest, straightforward, super responsive, and take genuine pride in their work, so it was really refreshing. If you’re looking for a solid, reliable HVAC company, I would HIGHLY recommend them. They seem like they really care about their customers and the work they do."

Air Conditioning questions, answered by experts

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

An AC drip pan may stop draining if there’s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line.

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.

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.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power.
