"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."

"Excellent friendly service from initial scheduling an estimate to very quick scheduling installation after I got the EV charger. Installation went very smoothly and was exactly how I wanted it placed and returned the next day to caulk to add an extra weather shield and if willing to help make certain everything works when charging my vehicle Highly recommend!!"

"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 simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

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.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

Your AC might not cool after a power outage because of a tripped circuit breaker, blown fuse, or damage to the compressor or capacitor. If you notice your AC not working after a power outage, in most cases, the breaker has tripped or the system has built-in brownout and blackout protection. Reboot the AC by turning it off at the thermostat, resetting the circuit breaker, and waiting 30 minutes to turn the AC on again. 

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.
