"These guys are awesome. They are totally nerdy about HVAC and I love that they really tell me and actually know what's going on. I own a commercial building and have 4 HVAC units (all in different stages of disrepair) and not-a-one did I have to replace because they FIXED THEM ALL. They have already saved me thousands of dollars and they're also cool and easy to be around which is an added bonus. Highly recommend this local business!"

"Absolutely amazing! A/C stopped working. Kenny called immediately after I put in a request for service. Two hours later, not only was he there, but he had the problem resolved and my A/C back up and running. All this happened in the middle of summer with 100 degree days. I cannot thank him enough! Will definitely be using him in the future for all my HVAC needs!"

"I liked how quick Right Now Heating & Air installed the system. I also liked that they kept their word without arguing about the small things. I did not like the way they set up the system, especially for the price."

"We had what we thought would be an easy installation of a ceiling fan in our spare bedroom/home office. With the HVAC system also near that space and the position of the fan, they had a lot of challenges that we didn't anticipate. They were very professional in explaining what they encountered, how it might impact our final cost, and what our options were. They were so prompt, courteous, and professional that we now use them for all of our electrical projects and needs including routine maintenance and checks."

Heating and Air Conditioning questions, answered by experts

The best way to save money on HVAC repairs is by regularly having your system inspected and maintained. This can prevent bigger problems and costly repairs and replacements in the future. It’s also smart to buy quality equipment and hire companies that provide warranties on equipment and labor. If you need repairs, you may be able to save money by cashing in on rebates and incentives or keeping the area around your HVAC unit clear to shorten the time your contractor needs to spend in your home.

You might notice that your air conditioner isn’t running as effectively as it once did. Specifically, your AC unit could take longer to cool your home, or it might struggle to remove humidity from the air. Higher utility bills and hissing sounds coming out of your AC could also indicate a leak.

While many states do not have specific licensing requirements for HVAC companies, your local city or county might. It's always a good idea to check local requirements online and use a tool like Angi’s contractor license lookup to confirm that the company you’re considering is licensed. Regardless of licensing, you should always ensure the company you hire is fully insured to avoid potential lawsuits if a technician is injured on your property. Additionally, it is recommended to check if the company holds third-party certifications, such as North American Technician Excellence (NATE) certification or R-410A certification, which qualifies them to work with HVAC refrigerants.

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected. 

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.
