"The vendor was very nice. Prepared. We investigated the issue together and identified next steps. No issue was found and he let me know ahead of time that if he cut the drywall, he would not be replacing it. But, he did clean up after himself, which I appreciate."

Heating and Air Conditioning questions, answered by experts

Your AC might not cool after a power outage because of a tripped circuit breaker, blown fuse, or damage to the compressor or capacitor. If you notice your AC not working after a power outage, in most cases, the breaker has tripped or the system has built-in brownout and blackout protection. Reboot the AC by turning it off at the thermostat, resetting the circuit breaker, and waiting 30 minutes to turn the AC on again. 

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit. 

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

Florida rooms can have heat or air conditioning, although not all do. These rooms can be added to the existing HVAC system or use a mini-split system, or they may just use a ceiling fan or the breeze from the windows for cooling. Florida rooms with air conditioning often have glass windows to keep the cool inside instead of just mesh screens.
