"Had my spring maintenance done and couldn’t be happier with the service. The technician was on time, professional, and took the time to explain everything clearly they also swapped out my nest thermostat for an ecobee and got it set up. Everything is running great and I highly recommend Pass One Hour."

"B and D is very professional in all aspects of the work. Always on time, precise in his work, treats the job like he was working on his own home, has a great play list on his radio, and ALWAYS leaves the work site clean and neat. He even used a blower to clean off the front porch every night whether he worked on it or not. I have no reservations in recommending B and D for all aspects of your job. High quality!"

"Call this electrician! He s worth your call, don t wait for him to call you! He was fair, honest and went above and beyond our expectations. We got two other quotes, one being from another company (Service detectives) who charged us $89 for a QUOTE and then quoted us $19k for everything we wanted done. For the things we needed done (not the whole house but a new meter outside, wiring to the inside, new panel and several outlets rewired) Holtzclaw Electric did for 3 times less than S.D. Just call Brandon. You won t regret it."

Heating and Air Conditioning FAQs, answered by experts

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

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.

It depends on the specifics of your warranty. The motor is likely not covered if you’re working with a limited warranty. The same goes for other components like the compressor and evaporator coil. Some extended warranties will cover the blower and fan motor, so read the fine print before signing up. Additionally, the manufacturer may offer a warranty for the parts, including the motor, though there’s likely to be a strict time limit for this coverage.
