"We needed our 16-year-old HVAC unit replaced, so I narrowed my Angie's List search down to seven Heating & Air Conditioning companies. The ones I chose all had an "A" rating with good reviews. Of those companies, two of them never returned my call, and one didn't work in Los Angeles (it's in Burbank but doesn't work in LA--go figure!). When I called Air-Tech, Heather, the Administrative Assistant, answered the phone--very friendly--and scheduled an appointment. Alex Fish was the Comfort Specialist that came to our home. He was on time, and called me on the road to let me know exactly when he'd arrive. Alex is very knowledgeable; studied every room, looked in the attic where our furnace is located, and examined our condenser and its power supply. Then we sat down and he showed us an illustrated booklet of a house that describes just how an HVAC unit works in a typical home. He walked us through the different systems and gave my wife and me options. He called the office to see if we qualified for an LADWP rebate and a Lennox rebate. We did. None of the other companies we'd seen were this thorough. Before he left, he had written out a detailed proposal including model numbers, what they do, the all-new gas piping, and drain and refrigeration line specifics, etc. Alex was the only person we had seen that wrote a complete proposal before he left the premises. A few days later, I called Alex with additional questions, and he talked to me for 20 minutes answering every question and concern I had. The job took a week to complete, and Carlos and his team covered the work area each day, were very professional and cleaned up at the end of the day, like they had never been there. Many of the technicians have been with Air-Tech for years. To me, that really says something about the company. My wife and I decided to go the permit route. Air-Tech pulled the permits, scheduled the duct testing (we passed), and Heather informed me of what was required with respect to smoke detectors, carbon monoxide detectors and their proximity to any ceiling fans in our house. Because of her heads-up and the outstanding workmanship of the Air-Tech team, final inspection was a breeze. Two techs even came out to double-check everything before the inspector arrived. I can't say enough about Air-Tech. A company that is honest, professional, and does excellent work. For any heating or air conditioning needs, Air-Tech cannot be beat."

"I am so glad I did not try to install our new dishwasher myself. Joseph Rand came out from All City Plumbing. We had some difficult existing conditions and our technician finished the job fast, clean and made it look easy. When I call All City back to my home for another job I will request to have Joseph come out.."

"Amazing service from start to finish! The technician was very friendly and professional. He inspected the air ducts and showed me the dust buildup inside the vents. After the cleaning, the airflow in the house improved and the air feels much fresher. If you need air duct cleaning or HVAC service, I definitely recommend this company!"

FAQs for air conditioning projects in Mount Baldy, CA

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.
