"The owner, Steve, came out and explained everything and more that I should be aware of regarding the replacement of the 26 year old furnace and Air conditioning units. He was a pleasure to work with and the price quote was more than acceptable. I did accept and within the week the crew arrived to do the installation. Al and Damien were very professional and the work was extremely well done. They finished that same day and when they left it was if the new units had always been there. I was extremely impressed and will certainly go back to them for future maintenance. You can't go wrong with this company!"

"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.

"Francisco of United Heating and Air Conditioning is the greatest, and I will hire him again happily and hope to have him service my system yearly going forward. He came today as promised and found that my thermostat only needed batteries, but my system was otherwise fine. He is very good and extremely honest and informative."

"I called yesterday and Ron came out today. This is the 3rd time he's helped us with furnace or central air issues. He found a sticker wrapper by the filter and found that the filter was the wrong size. He's always really friendly and professional.

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.
