"I called Smart Heating and Air Conditioning for a quote to replace my AC unit. Mike, came out and took his time with the inspection, and also took his time explaining to me everything that needed to be done. The pricing is competitive, but definitely worth the money. The whole install went perfect."

"To start, I put in for an emergency call to Freschi and was told they would call me 30 minutes before. They never called me back. Freschi sucks!!!I I also put in a request on HomeAdvisor on Thursday night and was given Global Warming Heating and Air as one of their verified contractors. I got a call at 7am from Rudy. I called back around 830am and we made an appointment for 1130am. He showed up at 1105am and quickly diagnosed the problem. He recommended replacing the furnace(which houses the blower assembly) due to the cost of repairs and its 17 year old condition. He didn t try to up sell me for an entire new system. He said my AC is working well so there s no need to replace it. I decided to replace the furnace and he said he d be back around 130pm. Rudy and his crew were back by 1pm. From the start of demo to it running again was less than 2 hours. Rudy s customer service is top notch!! From now on, I will only be calling Global Warming Heating and Air. I can t say enough good things about Rudy s business ethics and timeliness. A+++++"

"Great team. While the job is messy as they have to work under your house. Aire Serv was great to work with. We needed new ducts and boots and my house is now moving air better than it has in twenty years. Highly recommend Aire Serv."

"I bought my heating and air conditioning systems through Perfect Star, and use them for a heating, and an air conditioning tune up each year. They work is exceptional, as are the employees. I have recommended perfect star to friends, who all were more than satisfied."

"Excellent customer experience from beginning to end. Alex was very professional, honest, and not aggressive for my business. Huft provided $4,000 in rebates and a $1,600 promotional credit for an electric HVAC system upgrade! The installers were prompt, expedient, and considerate to not make a mess. The workmanship was great in the interior attic and for the exterior condenser. They cleaned-up afterwards and left no trace or trash. They even ran diagnostic tests after installation and provided the written results with follow-up 6 months later to inspect and make any adjustments. I would highly recommend Huft Heating and Air Conditioning for a new HVAC install."

"Exceptional company, exceptional work done for us. We had an emergency need with a failing furnace. 411 was able to come out on Sunday, the same day. Our HVAC system was 35 years old and I knew it needed to be replaced, and they were able to do so within two days. In addition, they were able to identify why our upstairs remained hot in the summer despite air conditioning. They were able to install a withdrawal vent that will greatly increase the removal of hot air in the summer, and therefore the effectiveness of our air conditioning. All this was done at a very competitive price. I feel very lucky that they answered our call that day. I can?t recommend the more highly."

"My furnace quit working about a week ago. I called a different company; they sent a technician out. He told me that the blower was frozen, and since the furnace was made in 1969 I wouldn't be able to get parts for it. He said I need a new furnace. Wonderful. His company gives me an estimate of $4800-$5300. A second company gives me an estimate for $5800-$7400. I called Albert Nahman Plumbing and Heating for the third estimate. Tony shows up on time, I tell him I've been told I need a new furnace. He takes a look at the old one, starts digging around in it, and has it working again in about 30 minutes! Tony was professional, extremely competent, and knowledgeable about the replacement process (that I no longer needed). To say that I am happy with not having to go through the hassles of a furnace replacement is an understatement! Tony saved me thousands of dollars and days of what would have been wasted time waiting for code inspections, not being able to leave the house, etc. THANK YOU!"

"Jim's Air Systems had the best value for my dollar. They supplied me with better equipment than they quoted for the same price. They completed the entire installation in about five hours. They protected my floors with tarps and were very careful to protect my walls as they moved equipment in and out. Josh, the son of the original Jim, was on the job working with the other two installers. They performed above my expectations. They left my home and yard as clean as if they had never been there. The new furnace is wonderful and is already saving me money on my P.G. & E. bill. I would recommend Jim's Air Systems unconditionally to anyone in need of a new furnace and AC system. This is a family business that has been supplying and installing systems since 1976. They take personal pride in doing an excellent job. They did not sell me anything that I did not need and provided me with a much cleaner and easier-to-service installation than my existing system. They are the best!"

"Truthfully, we had angst about calling for service because of past experience with other HVAC vendors. They always said the same thing, our system is "old" and we need a new one. Very expensive! We called for service, not a hard sell! Hence, we never used the same one twice. However, Tyndall gave me the impression, whether right or wrong, that they would be less likely to do this so I decided to try them. They kept me informed of their arrival status, since they squeezed me in at the end of their work day the same day I called. So, communicative and accommodating! After running several tests, they determined it was an electrical problem and nothing to do with the unit itself. They also said our unit doesn't need replacing - that's a first! They didn't do any unnecessary service or repair to run up the bill or even try to convince us it was needed. We were only charged the minimum fee as quoted. We were able to repair our air conditioning without the "hard-sell angst". So, thorough and honest! Unlike the other HVAC vendors we've used, we definitely will call them if we need service again!"

FAQs for air conditioning projects in Brentwood, 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.
