For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU.

"J & J Air, installed our new Trane system a couple of years ago and did a wonderful job. Installation went very well, on a terribly hot day, the team did a great job, with no mess left behind. We have had a couple of Mechanical issues 1 with a broken part, and 1 with a failed switch. Both times the J & J teams showed up on time and resolved the issues as needed. Jeremy and his team are to be commended for their efforts and their Customer Service."

Air Conditioning questions, answered by experts

A new air conditioner capacitor will cost less than replacing the entire air conditioner system. While a capacitor itself will cost between $8 and $25, paying a professional to replace an AC capacitor will cost $180 on average. It’s not safe to replace an air conditioner capacitor on your own.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

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.
