"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

No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building’s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners.

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.

A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. 

No, heat pump maintenance needs are very similar to air conditioners, including keeping outdoor units clean, changing filters regularly, and occasionally scheduling a refrigerant check to see if any has leaked out. Heat pumps typically switch automatically between heating and cooling, so you don’t need to worry about manually changing them every season. However, since they are always on call, they can develop wear and tear faster than an air conditioner.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.
