"Our central air conditioner stopped running, and I called Sharp-Long because they had originally installed the system and had periodically provided maintenance on it in the past. The owner, J.C. Crossley, went out of his way to send a service employee to look at the problem within an hour (it was at the end of the day).  The employee, who was very friendly, courteous and knowledgeable, determined that the coolant had all leaked out, re-charged the system with recycled coolant for free and ran tests preliminary to determining whether we could claim a utility rebate when we replaced the system.  I was extremely grateful for the courtesy extended by Mr. Crossley and strongly considered his bid for replacement, but in the end we did select another bidder. I offered to pay Mr. Crossley for the service call, but he declined the offer.

"For $39 you don't get very much. First, the receptionist seemed perturbed when I called to get an ETA for the tech. Upon arrival, the (grumpy) tech spent about a half hour. In the past when I paid other HVAC businesses $80+ they were on site an hour or more and seemed more thorough. The tech said nothing about my system or the service, but did leave a list services performed. Tech did not cover his shoes. Also, the tech did not say hello, goodbye or thank you. I think it's worth paying more for established service providers with a proven track record."

Heating and Air Conditioning questions, answered by experts

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected.
