"My heater required a part to get it to operate. They were able to get the part quickly and my heater back to working. I have used this company for all of my heating and air needs for 18 years. They are the best in all categories."

"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."

"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!!"

"I have had Jason wire two garages installing sub panels and all outlets. He also moved the meter box on a home because PG&E said we had to. He did good work things clean, and was quite pleasant to have around I would definitely hire him again as a matter of fact, Iâ m planning the next project soon"

"I recently hired a landscape designer to help me revamp my backyard, and I'm thrilled with the results. The designer was creative and listened to my needs, and they were able to create a beautiful and functional outdoor space that exceeded my expectations. The team was professional and efficient, and they completed the project in a timely manner. I would highly recommend this service to anyone looking to transform their outdoor space."

"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

To lower humidity quickly, run a dehumidifier or your home's air conditioner or turn on exhaust fans to extract moisture. These methods can quickly and effectively bring your home's humidity levels to a comfortable condition. However, you should consistently practice humidity-reducing tasks to maintain proper indoor humidity levels.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.
