"ACS installed my Lennox A/C system 4 years ago and have maintained it since. The A/C went out Thursday night and I called ACS early Friday morning. I explained to Sandy, the dispatcher, that I was sick and wasn't looking forward to spending time in a hot house. She was very understanding and arranged to have Manny at my house at 8:45am. Manny is a very professional and competent technician. He diagnosed and fixed the issue promptly (a blown fuse). He also recommended a couple of improvements to my system that would make a future outage less likely. I had him install a surge suppressor on the air handler and a hard start unit on the compressor. I have nothing but good things to say about Manny, Sandy, Patrick, Milo, Dustin, Daniel and all the other people I have dealt with at ACS."

"Temperature Control is our go-to company for air conditioning and plumbing. We purchased a central air unit from them almost four years ago. We have never had a problem with it, and we regularly have their system check-ups to keep it serviced properly. We just had a plumbing emergency, and they sent Manuel Valdez out to fix it. He was great. Mannie showed up quicker than we expected and worked far more than he should have had to, but he was determined that it be perfect. It is nice to deal with a company that leaves you feeling like you got your moneyâ s worth."

"James Cavanaugh and his crew very professional. Arrived promptly, explained the work to be done, answered my questions and addressed any concerns, and went directly to work, Very respectful of property and home. Worked diligently and wasted no time; theirs or mine. At the end of installation, they carefully explained the new features, such as the thermostat, and the new electronic air filter. James, the lead installer, particularly ensured I was satisfied with the the work done. Absolutely recommend this Company and their talented staff. Kudos to Taylor Owen who strived to satisfy my initial demands and give me peace of mind that I was getting the best price for the best product. Mr. Owen was very prompt in returning all my calls and behaved as if I were his most important customer!"

FAQs for air conditioning projects in Tucson, AZ

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.
