"It took two trips out for the turn-up of my new air conditioning unit. Second tech identified a wiring issue and replaced the leads and everything is up and running as expected."

"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?"

"They did very high-quality work! They replaced my furnace and air conditioning. They did a very highly professional job. They did it in one day, They replaced a Montgomery wards furnace of 53 years and air-conditioning, the new furnace and the air-conditioning work very well. A lot less money to operate, I went from a 60% or 96%."

"We had to have them out a couple times this summer to fix our A/C (not their doing, just a bad unit). We called the morning both times it quit working, and both times they were out that afternoon. By the time we came home our house was at a comfortable temp again. A very good company to work with. We have been impressed with each visit.

"Riley was the technician who serviced my air conditioner yesterday. Riley always kept me informed on the progress of the work he was doing and before leaving THOROUGHLY explained the condition of my air conditioner and what I can do to extend its life. Fortunately my air conditioner, even though it’s 11 years old, is in great condition and I plan on doing things to prolong its life. Overall I would give Riley a rating of 10. He is an exceptional technician, knows his job, explains things well, and personable. The cost today was $17 for a replacement filter."

"I recently had Prolific Mechanical install a new air conditioning system, and I couldn't be happier with the results. The young man who completed the installation was professional, courteous, and extremely knowledgeable. He took pride in his work, kept everything clean, and made sure the installation was done correctly from start to finish. The new system runs flawlessly and keeps the house comfortable even on the hottest days. I highly recommend Prolific Mechanical to anyone looking for quality workmanship and dependable HVAC service."

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.
