"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

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

Yes. Getting a whole-house dehumidifier can help you save money on energy bills. How? Your home automatically feels cooler when there’s less humidity in the air (“It’s the humidity that gets ya!” is such a true statement). This means that you won’t need to run your AC as much as you would if you had all that extra humidity in your home.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).
