"After a no call/no show by another technician (during 3 weeks of 90+ temps, a sick spouse, 3 tired dogs & a pandemic), I called Hvac Doctor after finding a referral on Angie's List. My call was promptly returned & I was honestly told I would be contacted if an opening presented itself. Within a few hours & much to my delight after a restless night of sleep, I was called & my central air was promptly & accurately repaired. These guys are top notch professionals as well as knowledgeable. Hvac Doctor is now going to be my new ongoing routine maintenance technician as well. Search no more, call Hvac Doctor! Can I give them 10 stars?"

"24 hour emergency service is excellent. Our air conditioning stopped working at night so we called at 2:00 am and a technician was out and diagnosing the problem by 11:00 am. Excellent customer service, friendly and knowledgeable technicians and very professional company overall. HIGHLY Recommended."

"Would 100% recommend this company to anyone that has HVAC needs. From start to finish everyone that I interacted with was helpful, knowledge, and kind! Spending a lot of money on a new furnace, air conditioner, and water heater is never fun, but Aquarius made it so easy. They listened to what I was looking for and make recommendations that would serve my needs (and not just the most expensive option). They were very accommodating with my schedule and were able to install everything while I was out of the State. Everyone made it easy for me to trust getting everything installed when I was not around."

"They retrofit a central air conditioner in our 1920s house with radiant heat (no existing duct work) and it looks great. It is February so the AC canâ  t be run yet, but I expect it to work great. They worked quickly and left with the house just as clean as when they arrived! Thank you Hero!"

"I feel I was over charged for and made mistake of not getting more estimates. I checked with 3 other companies that were $1,000 less for installing the same air conditioner."

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.
