"I have had Maynor maintaining my heat, air and hot water heater for 18 months now. Communication is great and the technicians explain what & why they are doing as they go. We just had our systems checked by Matthew J. He was very pleasant and thorough. I have recommended Maynor to my neighbors and friends."

"Comfort Monster did a superb job diagnosing and servicing my HVAC. I called late in the day and scheduled an appointment the next day. The tech checked multiple sources to troubleshoot the issue. He was able to get my unit running in under 30 minutes. My unit is very old, so I requested a quote for a new system and received a very sensible estimate in under 24 hours. In contrast, I was told by a tech from another company I needed a replacement unit. I feel that Comfort Monster really took the time to address the underlying issue rather than just try to sell me a new unit! I highly recommend Comfort Monster and Ben!"

Customers say: True professional
"I have been without A/C for about a week went on Facebook marketplace 𠤦ð ½â â ï¸ ð ¤ and after 2 so called Hvac companies come out and charged to come out the problem still persisted. I try Angieâ s list and I go with the first recommendation without looking at reviews. The owner personally called me back and understood my frustration and came the same day to inspect the unit. Less than 15 min the problem was diagnosed the very reasonable was agreed upon and the work was done in less than an hour. The owner was very professional and answered every stupid question I had lol even gave my son some advice about his future. Thank you for the service and professionalism and i highly recommend RPS for all you Hvac needs. Plus your helping support A Small Local Business"

"ARS did a very good job installing my air conditioning unit. They took the time necessary to move a piece which was in the way of installation. Then it was put back in the appropriate manner and when a part didn't work, they rigged it to work until the part could be replaced. The part was replaced the next day and the AC works as it should."

"Our AC broke at the worst time: Memorial Day weekend. We called several emergency repair companies before Dominion Services, but none of their emergency technicians got back to us. We waited for over twelve hours in our hot home for someone to call us back. Finally, we used Home Advisor to contact Dominion Services Heating & Air. We immediately got a call from the company to confirm our appointment! The technician (Tarone?) was at our house within an hour and had the problem fixed in 30 minutes. I could have cried I was so relieved. Excellent service. We will definitely be using them for all of our future HVAC maintenance and services!"

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.
Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.
Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.
Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.
Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
