"We had Chris replace a decades-old gas furnace and electric water heater, as well as install central air conditioning. We talked to a few professionals in HVAC, and Chris seemed to have encyclopedic knowledge of it all. At a very fair price, Chris spent two days having the old stuff professionally removed, getting the new stuff (AC) wired up, and all the new equipment installed. This was a problem-free project from start to finish, and we would strongly recommend Chris to anyone with similar needs."

"This was the best service with 2 highly qualified gentlemen. They were both knowlegable and friendly. They arrived 20 minutes after the initial call which was at the end of their day. They could have gone home for the day like the bigger companies did but instead they stopped on their way home and serviced my central air condition system in the middle of a heat wave. Unlike the other companies that I called who couldn't respond for 3 to 5 days even after I explained I had an infant to keep cool. If you're looking for a reliable company MTS is where you should shop"

"The entire central air conditioning job was completed under the allotted time. Peter and his team were extremely professional, knowledgeable, thorough, left no mess behind, and their price for this job was very reasonable. I was so impressed that I scheduled him to go out and replace my daughter/son-in-law's two oil fired furnaces in the same week. I would highly recommend All Phase to anyone looking to upgrade or replace their mechanicals. Great job Peter. Thank you for changing my outlook on contractors, who many times, never keep their promises, and provide sub-par work! Thank you!!"

"The Fellowship Team recently installed a new boiler system for me and the experience was flawless from start to finish. Replacing a primary heating system is a major investment, but this team made the entire process stress-free. The installation was incredibly clean. The technicians routed the new piping with surgical precision, ensuring everything was tidy, secure, and easy to access for future maintenance. Since the install, my home reaches the target temperature much faster than before, and the unit runs so quietly I barely notice it?s on. I?m already seeing the benefits in my lower monthly energy bills. The crew arrived on schedule, was sure to not damage anything, and clearly explained how to use the new digital thermostat before they left. They treated my home with genuine respect. It is rare to see this level of dedication to quality. If you need a reliable, high-performing heating system installed by pros who actually care about the details, look no further. Highly recommended"

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.
