"We called United Heating and Air Conditioning for an annual furnace inspection for our new home. They scheduled quickly and easily. We then had a conflict and they re-scheduled just as easily. When they inspected the furnace it turned out it was extremely old and no longer safely operable. We required an emergency replacement. This was in November and we didn't want to be without a furnace. United Heating and Air Conditioning was able to come the next day (!) and install a new furnace. They took care of the installation, confirmed it worked, and hauled away our old furnace. They were quick and professional and stuck exactly to the quote. We were extremely satisfied and will definitely be reaching out to them when it's time to check (and possibly replace!) our air conditioning unit. Highly recommend!"

"We were very pleased with the whole experience. KC did an excellent job of breaking down our options, with honest feedback on the pros and cons of all of the furnace options available. The technicians were polite, considerate and informative. I am hoping not to need any services soon, but if I do they will be my first call."

"Angel and Tyler worked their butts off to help us with our air conditioning. They unfortunately had to do way more work than expected, however they were at our house late and always stayed in communication on what was going on. They did a great job and were very detailed and thorough with all testing making sure that the job was done right and there were no issues. We had a great experience!"

"HIred company for a whole house humidifier installation/replacement. Don was very professional and thorough; he made sure we had the right system for our house. Additionally, he not only took the time to make sure that we knew how to work the system when he left, but also explained the reasons that he installed it differently than the original installation. The price for the installation was also more competitive than the other service providers that we were matched with for the job."

But one man doing the job wasn't bad, cleaned up everything, took the old junk and he even bought his own wasp spray to use on the outside air wasp are really mean you know) Yes, I would use him again."

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.
