"After numerous "pros" came to repair my HVAC system, I always got the same response....you need a new system for 8.5 to 12.5k. What they don't know is I know enough about these systems to know the cost of parts and how the system works. So when the "technician" shows up and says they don't know which of the 5 parts was a problem, I'm skeptical. I just don't want to fix everything myself anymore. Comfort Monster is different. The difference is their technicians do not work on commission. Repairman from other companies get paid when the customer has to buy a new HVAC system, giving no incentive to fix anything. Comfort Monster technicians take pride in solving the puzzle of why the machine isn't working. I have two systems and when they inevitably have a problem, I'm calling these guys. Dude even gave my little girls Comfort Monster plush toys and they carry them everywhere!"

"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!"

"Very satisfied with the outcome. The house was not occupied while this work was being done, so I was not present during much of the work to observe the installation of system & ductwork, but it worked beautifully once we moved in and began to use it, a turnkey experience. Twice since then we've had questions (e.g., Can we move the ductwork in one part of the attic to accommodate new attic stairs?), and both times they were very responsive and came out at no charge to me, despite the fact that the work was done over a year ago. I've interacted with both Mike (the owner) and with one of his technicians, and have been very satisfied with the level of customer care I've received. I will use them in the future for our heating & A/C needs.

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.
