"We decided to use Shavitz Heating & Air Conditioning as the company for the install of our new furnace. What impressed us about Shavitz was their employees. They made the entire process a positive experience. Everyone that interacted with us had a friendly and professional demeanor. It started with the sales visit by Will Gutierrez who was a pleasure to deal with. He provided us with several options while never pressuring us to lean one way or another. He was patient with us and answered all our questions. His courteous approach gave us a positive view of the company he represented. The installing technician, Linas, and the tech that was assisting him only continued this professional trend. They both were equally as courteous. Once the work was complete, Linas made sure he answered all of our questions and that we felt comfortable with the operation of our new furnace and humidifier before he left. His patience was very much appreciated. He also made sure the area were the work was done was clean and all trash removed. Will Gutierrez followed up with us a few days afterwards to make sure all was well, and that we were pleased with the work and our new purchase. Our answer was a definite, yes."

"The technician came out yesterday, June 5th and did a diagnosis on my air conditioner as there was a significant cooling disparity between the upstairs and downstairs of our two story townhome. I was expecting to possibly replace the A/C as it is getting older. However, the technician stated the AC is in good working condition and that there was a slight leakage factoring into the cooling discrepancy. That was a much less expensive repair or fix vs. replacing the whole equipment. I appreciated his honesty, time spent communicating the issue with me and professionalism. I would definitely use All Temp Heating and Air Conditioning again and recommend them to anyone dealing with air conditioning issues."

"Awesome. While I probably could have scrounged around for a slightly better price, the speed, professionalism and quality of the work more than made up for it - and currently being unemployed, I don't say that lightly! They literally came THE NEXT DAY and did the entire install - remove old unit, rework the ducting, install an air cleaner, dress the wiring - all in one day! The job was done with expert quality - no loose wires or hoses lying around, everything square - and they even came back a few days later to make sure the sump pump and humidifier wire working correctly. finally, they called me a week after that, to make sure I got the Peoples Gas rebate paperwork together! I'd recommend them to anyone!"

"AWE (Air, Water, Energy) did a great job. The installers arrived on schedule and worked all day to removed the old equipment and installed the new equipment. When they were finished, everything looked great and the work area was completely cleaned up. The air conditioner has worked great all summer and kept our house at a comfortable temperature. I am looking forward to a similar experience with the new furnace, also. After the system was installed, AWE sent an inspector to our house to make sure the job was completed satisfactorily (which it was) and take pictures of the equipment to make sure it was installed correctly (which it was).
FYI, we have been a customer of AWE for over twenty years because of the great service they have always provided. This was the 2nd furnace and air conditioner we have purchased from them. They also installed our current water heater. The technicians are always very knowledgeable and friendly. They always arrive when they say they will arrive, and do what they promise. The services provided have always met or exceeding our expectations. I would recommend AWE to everyone.

"We were very happy with American Family. Their bid was competitive and the installation of our new air conditioner went very smoothly. They removed the existing system and were great about not destroying our landscape. We had them install the new system in a new location, away from the back patio. So far everything seems to be running fine and I would happily recommend them to anyone."

"Excellent. Technician arrived timely. Tech was extremely courteous, professional and gave detailed explanation of central air system operating status. We have had Four Seasons perform seasonal check up on our heating and air conditioning system, and repairs when required, for over ten years."




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.
