"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

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

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.

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.
