"TeamEnoch replaced my old air conditioning and heating systems, and the work they did was so good it borders on the unbelievable. Two very professional technicians showed up exactly on time, worked for 11 hours straight in really horrible conditions (a cramped attic in 95-degree heat) and did the whole job in one day! To top it off, their company’s price for all this was significantly lower than other estimates I had. This is a great company. I can see why they have won so many awards. *This review was migrated from an affiliated account on Angi with an original submission date of 10/4/2021"

"Chad arrived on time. He and his crew were very courteous and professional. He and I had both initially thought that I had a slab leak based on the symptoms. But once Chad got an air compressor hooked up to the water line to blow the water out, he found the leak to be in the yard where a landscaping crew had capped off the old sprinkler system with the incorrect fitting. He and his crew got the problem solved in just a few hours. The price was considerably less than what we talked about if it had been a slab leak, so I was very pleased about that also. I would definitely recommend Chad and Priority Plumbing."

"Mechanical Comfort Systems installed a new heating and air system when my upstairs (where all the bedrooms are located) system went out in the heat of the summer on a Thursday (left for work and it was working... got home and it was 90 degrees upstairs). I had another HVAC contractor out before calling Mechanical Comfort Systems and their proposal was significantly more expensive for a lesser system than I received from Mechanical Comfort Systems (the efficiency of the system was an upgrade from existing, and other company quoted replacement with same efficiency as existing). The system was replaced quickly (on a Saturday), and the installers were great, very professional. They cleaned up after themselves, and did a great job. During the freeze this February, I had a water pipe freeze and burst. Mechanical Comfort Systems came out the day after, even though driving conditions were still terrible and all my friends in similar situation were being told it'd be several days to a week before a plumber could come unless they paid some ridiculously expensive emergency fee... I recommended Mechanical Comfort Systems to three other people I knew that also had frozen pipes burst, and they all had them come after fix theirs after I gave them Mechanical Comfort Systems information. I strongly recommend Mechanical Comfort Systems to anyone needing any plumbing or HVAC work. I'll definitely use them again... although I hope not anytime soon ?"



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.
