"If you are fond of Family run businesses, AirTight Air, Inc. is for you!! Ryan & Julie Coppens made me feel like I was part of their family. Ryan performed all the work and meticulously installed my new HVAC unit, attic fan, ducting and registers, but the best part is the air purifier. My house smells so fresh and clean. Thank you AirTight Air, Inc!!"

"Eddie and Lennon are pros. They were the first company to call back after leaving a message I need help. I hired them to check the air conditioning and discovered it had a big leak. After looking and talking, the system including the furnace needed to be replaced. I decided to change the system after negotiating a price and they started to take out the old air conditioner and heater that afternoon and come back the next morning to install the new system. I asked Eddie if he could install a Nest Learning Thermostat I had purchased and he said no problem. They did cleaned up like they were never there. The new system works perfectly and with less noise too. Champion Aire Heating and Air Conditioning was the right choice to hire. Very satisfied customer and would hire them again for maintenance when needed."

"Two technicians came, Jeremy and Ryan. They were great. They checked the thermostat, the electrical board that looks like the motherboard to a computer, some plastic pipes and the air filter. My bad. I went miles too long without replacing the air filter. Their explanation helped a lot. It reminded me of people and how if they take care of themselves, their internal organs don't strain as much to keep the body going. That's what happened to my a/c. I didn't take good care of the filter, so it had to strain a lot harder to keep going. They said I should replace my air filter every 3-6 months. I am so grateful that they came out so quickly because it gets very hot in my condo on the second floor. Again, great service, excellent attitude, prompt and outrageously good prices. I shudder to think of the companies that would claim all kinds of stuff "under the hood" and overcharge. I consider myself very lucky.

"Bill Walker is the tech that diagnosed my faulty condensing unit compressor to be grounded. Sounds like a good thing right? but its not. You never want to hear that. Should you ever do so you want Trabuco Air handling it. I was explained what was wrong and given options that i could comfortably choose from without just breaking the the already shaking bank. Trustworthy and reliable Bill is a cool cat and confident in his skill set. He knows air conditioning extensively and will solve your needs as well. I can finally enjoy the upstairs again thanks to Bill from Trabucco Air."

"Very in detail description of what needed to get done and the why behind it. Awesome job, professional, answered every question on why my central AC was strong on first floor but very weak in second floor. Air handler moved from bottom floor to upstairs attic, higher capacity central AC and all ducts changed. Beautiful work done in 3 days with detailed report of what was done. Fair price for the job done. Before and after."

FAQs for air conditioning projects in Murrieta, 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.
