"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!"

Customers say: Quick response

"We had an unusual situation with the remote lighter in our fireplace... First, we had the gas company out and they could not fix. We were connected to NT Electric and HVAC through HomeAdvisor. Nathan came out later the same day and diagnosed the problem and the solution and offered to go find the special part required and return the next day. I would recommend him to anyone looking for a reliable person to fix anything related to electronics or HVAC."

"Sam, who came out to give me an estimate for a new system, found out that the old fan motor was the culprit and recommended that we just repair the motor. He explained things in detail, helped us to save money in a genuinely sincere attitude, I was impressed how good his service was, and I recommend him for any HVAC issues. I will be using him in the future."

Heating and Air Conditioning questions, answered by experts

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.

A one-stage air conditioner only has one setting, while a two-stage air conditioner has a high and low setting. A two-stage air conditioner costs between $500 and $2,500 more than a traditional air conditioner, but it has a longer lifespan and helps to increase energy efficiency. To make this decision, you should consider your energy needs and available budget.

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. 

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.
