"Metro Air did an excellent job! I highly recommend this company, especially Ron, my technician. At first I thought i just needed Freon , then thought it was a bad capacitor, come to find out I needed a whole new outside unit. The price was on the higher end of the spectrum when I googled comparable pricing, however the customer service I received was excellent. All care was kept in keeping my home, inside and outside, clean and tidy. Ron was prompt and pleasant to work with. They work on Sundays, and came out immediately when I called with my air troubles. Great company! Thank you Metro Air!"

"4 Seasons was great. They were able to do a repair within a couple of hours of me calling. I had waited all day for another service company to just even get a tech assigned with no idea of expected arrival. 4 Seasons assigned someone immediately and we had air conditioning within a coupe of hours. The technician was very knowledgeable and professional. Highly recommend them!"

"I contacted Team Enoch yesterday and they promised a tech to diagnose and fix the problem today. Chris G was dispatched and he quickly diagnosed the AC issue. He explained what had likely occurred and why the part needed to be replaced. I was pleased not only that he had the replacement part and could fix it immediately but also that it was under warranty! Chris was professional, personable and very knowledgeable. He got my AC working again at a fair price and took a load off my mind simultaneously. Thanks Chris snd Team Enoch!"

"He works on Sundays for no extra charge. When I did the request to be contacted by three companies, he called within 30 minutes and was at my house two hours later. Haven't heard from the other two. Very professional. The charge was $300 to unplug lines in air conditioning units (2) and install safety valves that will turn off A/C if leaks occur. I called because my house smelled like mothballs!"

"HVAC system went out and needed a new one on short notice. Team Enoch responded the same day and were out 2 days later to replace the HVAC system. Installation was done meticulously and with great care and the price was very fair. We paid about $6000 for a 4 ton American Standard (aka Trane) system. The first company that quoted me estimated $8900 for the exact same system and undoubtedly lower quality of work (Abundant Air Condition and Heating). Miles was my point of contact and did not try to push a sale and encouraged me to do some research for myself. Overall great experience, will definitely call again if anything else comes up with my electrical/plumbing. *This review was migrated from an affiliated account on Angi with an original submission date of 7/27/2019."

"Finally found an HVAC company I can trust. HAP gave me a fair quote, showed up when they said they would, and completed the job cleanly. My house is cool again and I couldn’t be happier. 75104"

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.
