"I recently had a Daikin AC system installed in my home and I couldn’t be happier with Piggies Air Conditioning’s service. From the very beginning, Ruben was extremely knowledgeable, thorough, and informative—he made everything clear and easy to understand. The installer, was just as impressive. He was friendly, prompt, had high-quality workmanship and left the workspace immaculate. Piggies’ quote was competitive AND they offer AMAZING WARRANTY!! Overall, I was completely satisfied with the entire experience and would absolutely recommend this company to anyone looking to replace their AC unit. By far, the best family-owned HVAC company I’ve ever had the pleasure to work with. I appreciate their top-notch teamwork!"

"

My air conditioning unit completely died on me and there was a heat wave coming. I was panicking and a friend suggested I call NRG. That was the best advice I had ever taken. They were very friendly on the phone when I called to make an appointment. They were on time and they explained the different options I had, they were very nice guys. I decided to purchase a whole new unit it because it was time.

They installed it that day and they kept me informed every step of the way on the process and what they would be doing next. I was very satisfied with the work they did and the price was really affordable. Since the installation my house has stayed nice and cool and I've never had any problems with the unit. I would highly recommend NRG Heating And Air Conditioning. They're Awesome!

"He was very professional and promptly responded when I was stranded without AC with a 6month old baby in the house. He went straight to the problem, diagnosed it, explained the pricing and fixed it. Our AC has been working great since, and we were given a year warranty! I would highly recommend My AC Guy to anyone!"

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"They were extraordinary! Two of them came out and they were a little early. They worked cold for two and a quarter hours. They removed the screens, washed them, and dumped them appropriately. They were so fantastic that I actually tipped them on the side. They provided phenomenal service and I am very happy with them."

FAQs for air conditioning projects in Westwood, 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.
