"From start to finish I couldn't be more pleased with our experience. Cole Heating and Cooling were a literal God send. After a month w/o ac Brandi and David went out of their way to makebsure we got some. David was very upfront, honest, and fair. I appreciated his determination to try to help us fix a part to our ac. When ultimately he couldn't he again was honest about the sale of our new unit. Working with a local company has been amazing. The install moved super quickly and we now have ice cold ac. If you are looking for a great ac company, look no further! Would highly recommend 1,000%."

"I can't thank Jon and his team enough. I've been a customer of JonBoy's for a couple years now, and I will be forever! They are incredibly honest, trust worthy, and reliable which I appreciate. Before I found JonBoy's, I endured a horrible upsell episode with another local company. It was a very unsettling experience that I will never forget; I was quite mortified! So now, JonBoy's is the only Company I trust with my HVAC system. Many thanks to JonBoy's team! They are my Peeps!"

Heating and Air Conditioning questions, answered by experts

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

Turn your system off when you're toasty or when you're out to prevent unnecessary wear. Using the timer on your thermostat so that it switches off when it reaches a certain temperature or turns on just before you get back from work is best. An annual maintenance contract can be helpful to ensure your system receives these important services at regular intervals.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

Modern AC leak sealants work as a temporary measure to stop refrigerant leaks. You can purchase them at most home improvement stores or on online. When using an AC leak sealant, keep in mind that it’s only a temporary solution, so you’ll still need to hire a pro to install a replacement part as soon as possible.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.
