"Extremely well. William, Mat, Joe, Raul, Eddie, & Phil (hope I didn't miss any of the crew) replaced two HVAC units with Daikin Fit Inverter Systems. They arrived on time, were very courteous, knowledgeable, and professional. The quality of work was outstanding (they even fixed a few electrical glitches). If the systems perform as well as the installation crew, we will be extremely satisfied customers. Of course only time will tell with respect to the systems, but I would highly recommend ACS Air Conditioning Services."

"Sean not only did the job quickly, efficiently, and correctly, as hoped, he was wonderful to have around! Nice, very professional guy and that’s not something that happens every day. L & M Home Comfort has great customer service. From the first phone call to schedule the appointment, to the completion of replacing the old burned out furnace board which is now working again and heating the house! Don’t waste your time calling a local plumber do yourself a favor and call L & M Water Heaters, Tucson Arizona 520-245-6209. We couldn’t ask for more! Thanks Sean!"

"Hired Johnny to help assemble a Murphy bed in my guest room. He was great from getting a quote and booking the install. When he and Colby arrived they were very professional and respectful of my space. They cleaned up after. Most notably the install is solid. I myself was not confident about hanging with my wall material but they did a wonderful job."

"Eric was personable, professional, and prompt. He removed two old heat pumps and gas furnaces and installed two new heat pumps and air handlers in 3 and a half days, working by himself. Once he started, he continued working uninterrupted until the job was done. Couldn't be more pleased."

"To say we were happy with Temperature-Control would be an understatement of the nth degree. We hire T-C to install a new, high-end Trane heat pump & air handler in our home. At every step they were professional & responsive. They showed up on time, sent pictures of all employees visiting our property, answered every question we asked and a few we hadn't thought of. The work was done on-time, everything was clean and neat and they checked in at many steps in the process to ensure we were happy and understood what was going on. So far we're 2-3 weeks in with the system and it's operating great. I would recommend this company quite enthusiastically to anyone looking for a new heating/cooling solution in their home."

FAQs for air conditioning projects in Sierra Vista, 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.
