"Before I called Maynor, I had 4 other companies give me an hvac replacement quote. Maynor was the 5th. I was very impressed with Mike who gave me the estimate. He exactly gave me the picture of what HVAC I was going to get and gave me choices and time to think about it. I decided to go with Maynor because of their reputation. NATE certified installers. I was right. Junior and Biri came to install my trane hvac with both heating and cooling. I also had zoning done. Very professional. Came on time at 7:30 and finished around 4 pm as I had zoning done the same day. Very impressed with the work done and the efficiency is to say the least. The next day, Jaime (supervisor) came to my house and reassured me that everything is working great. I appreciate the reassurance as it is a big investment. They are open 24/7 and they listen to your needs. Competitive quote and honestly lower than everyone else considering the quality of work. My heating was in the attic and the work was outstanding (I took before and after pictures and inspected everything they did). The zoning works perfect. If you are looking for quality, efficient and superb work, go for Maynor. You will never go wrong. I had researched, read all reviews and got estimates from 4 other big hvac installers. I was not convinced until I met Mike who was honest, detailed and organized. The only one who gave me the specific model number of the hvac I was getting and educated me regarding the different kinds of hvacs. Also, he did not push me to go with other brands like all the other 4 companies did. Maynor took care of me and I know they will take care of you too."

"Dominion Services replaced my 30-year old HVAC system (the outside compressor, and the inside air handler) with a modern one having a 50% increased efficiency rating. The quality of their work is high (four friendly employees with more than 100+ years' combined experience were involved) and have good flexibility to adjust to my work schedule. They easily adapted the new system to the existing hook-ups, and were flexible in their selection among alternate, reliable replacement HVAC systems. The replacement cost was well within the range of the national average. I recommend contacting Dominion Services for insight into any HVAC issue."

"Lahcen is an excellent HVAC technician! He quickly diagnosed the issue with my AC unit and clearly explained what was causing an error in my AC unit and while he was diagnosing the main issue, he checked my filter he found out it was upside down. Professional, knowledgeable, and honest. I highly recommend him to anyone needing HVAC service."

"J. Stewart was able to accommodate a last minute move out cleaning over the 4th of July holiday weekend. His services and pricing seemed fairly priced for the lead time on work requested with the holiday weekend."

Heating and Air Conditioning FAQs, answered by experts

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

No, not all HVAC systems have a fresh air intake, but there are many advantages to having one. For example, a fresh air intake can boost the air quality inside your home and help your furnace run more effectively. Plus, it can make your house more energy efficient, possibly saving you money on your utility costs.

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.
