"Gordon, Harrison and Louis did an absolutely fantastic job with installing a brand new HVAC system into my old house. The house was not designed to include AC so they had to be very thoughtful in the process of figuring out the best way to install all the equipment. They were on time every day and always kept me informed any issues and next steps.. They did it and we will enjoy the benefits of keeping cool this summer."

"I had a great experience working with Cool Air Technologies. Bill and Trish McIntosh are fantastic. Great personal service and super friendly. When I first met Bill, I explained to him that I had recently purchased a new home and was in the process of making some upgrades to my existing home so I could covert it to a rental. I didn't have any air conditioning so that was my priority but I was considering replacing the original furnace at the same time if the price made sense. However, I didn't want to invest in a high end system since I wasn't going to be living there myself. Bill quoted me a great price for the A/C and new furnace so it made financial sense to do them both at the same time. One of my other quotes was literally double for the same scope of work. Bill came in with his crew and they were professional and efficient and completed both A/C and furnace installs in about 7 hours, including running all new piping and electrical for the A/C. I would absolutely recommend Cool Air Technologies and the personal service that Bill and Trish provide and I will definitely be giving them a call in the future for my new home. Thanks Bill for the great work!"

"Great. My daughter contracted Air Duct Professionals to do her home. James, the technician, was professional, knowledgeable and did a quality job. I contacted Air Duct to do my home and requested James. James arrived on time and did an excellent job. He also helped me with a leak with my HVAC Condenser and diagnosed and fixed the issue."

"Love these guys! A year ago we had a heatwave, and on the first day our air went out. Danny came out same day and took a look. The very next day they came out and installed an entirely new (and appropriately sized) HVAC. Since then, they've come out at the beginning of each season and given our system a tune-up. They're timely, super friendly, and knowledgeable. Brandon came out today and performed a complimentary service, and now we're ready for summer! I should mention, the system they installed rocks! Our house gets plenty cold/hot now, and quickly."

Customers say: Quick response

"I was out of town when my air conditioner stopped working. My mother called 2 companies to check it out. The repair men were interested in selling us a new unit not fixing it. I found NT Electric & HVAC online through Home Advisor while I was out of town. The company had good reviews. I called Nathan and scheduled an appointment. He assessed the problem and fixed it! I would highly recommend Nathan and his company. He does what s best for the customer. His prices are fair and reasonable. I would use him again."

Heating and Air Conditioning questions, answered by experts

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

Yes, a dehumidifier and air conditioner can be used simultaneously in a home. A dehumidifier can bolster an air conditioner’s efficiency. Typically, a dehumidifier is used when the air conditioner alone cannot keep a home’s humidity levels at a comfortable indoor humidity level, which should, ideally, be between 30% and 50%.

Aside from needing HVAC repair, there are times when you may need to replace your unit. HVAC replacement costs $5,000 to $12,500. Here are some telltale signs that your HVAC unit is going bad:

  • Your unit is 10 years or older.

  • Your home is very humid.

  • The unit keeps cycling without producing cool air.

  • You need to repair the unit frequently.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.
