"I purchased a new, fairly expensive thermostat. I needed a certified HVAC person to install it in order to preserve the 10-year warranty. I utilized Angi to find someone local to do that. I was soon contacted by Nick. We discussed a priced and he showed up the next day. Nick was extremely cordial. He was very easy to communicate with and he is generally just a very nice person. Nick was knowledgeable and completed the job in short order. He provided me with a receipt and then went on his way. I am very happy with his work and I think that if he does some work for you, then you will have a similar outcome."

"We pay $14/mo. and they automatically come out twice a year.  They come in January and check your heater and July and check your A/C.  Then you get a discount on any service needed.  It's great, they always are good. I think they're kind of expensive but, well they're probably no more expensive than others.  It always cost a lot when you have to have repairs done.  They are always very responsive when we call. They're always here within the time frame that they give us.  Only one time did they call and say they would be later."

"Jed went above and beyond installing my new ceiling fan. He had to get some supplies and worked in my hot attic and made sure that it was wired correctly. This involved cutting through the old inside wood 2nd layer roof to get to the hidden electrical wires where he put a junction box and new wiring for the fan and light kit. He stayed longer than necessary and completed the job that night after working all day. He is a consummate professional and I will hire him again. through"

"Yesterday it was 112 degrees and so it was the perfect evening for our AC to go out. We tried cleaning the coils and all the DIY tricks we could think of, but when we woke to the house still being in the 80s we knew we needed a service call. Dereck Nail was familiar with my HVAC from prior to starting his own business so it made sense to give him and his team a call. He got back to me quickly, understanding the importance of our household of 5 relying on not just comfort, but safety as well, and said he could squeeze me in the same day between appointments. He arrived at 9 am, diagnosed the problem, and replaced the broken $30 part. He is handling the warranty paperwork as well. In a time of huge businesses that treat you like a transaction, it's nice to see a company that exudes the hometown feel while still maintaining a high level of professionalism. It's like the old family doctor who you can get to know and who will take the time to explain the issue and make proper recommendations. I will definitely continue to work with Innovative Heating and Air in the future."

Heating and Air Conditioning questions, answered by experts

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line—the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.
