"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

The cost to repair an air conditioner averages around $350 to $450, but the price can range from $100 to over $3,000. The final cost depends on the type of air conditioner, the extent of the damage, and the specific parts that need replacement. For example, repairing a window AC unit typically costs between $100 and $250, while central air conditioner repairs can range from $300 to $3,000. A simple fix like replacing a dirty filter might only cost $10 to $50, but a major issue like a broken compressor could cost around $2,000 or more, potentially making it more cost-effective to replace the entire system. Due to the need for specialty tools and handling of refrigerants, repairs more complex than changing a filter are best left to a professional.

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.
