"Smart Heating and Air Conditioning was very responsive and came out when we really needed them. We were without heat as our old furnace no longer worked and our AC was on its last leg. Mike came out to give us a quote which was the best out of three that we had. He went over all options with us and now we are very satisfied to have a new and efficient heating and AC system. They lived up to their name as well, by upgrading my thermostat to a WiFi one that added that SMART touch to my system."

"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+++++"

"The crew from Albert Nahman did a great job from start to finish. The project was to replace the original ductwork in our 60 year old house. Tom provided excellent advice for the estimate then Bryan’s crew did the job, 2 days, within a week of my acceptance of the proposal. Great work."

"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!"

"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."

"I recently had a new air conditioning system installed, and I couldn?t be happier with the entire process. From the initial consultation to the final installation, everything was handled professionally and efficiently. The team arrived right on time, explained all my options clearly, and helped me choose the best system for my home and budget. The installation was completed faster than I expected, and they made sure everything was clean and working perfectly before they left. Thank you for a job well done!"

"Jaleel Porter from Bell Brother's Heating and Air, Inc. came to the house to install and trouble shoot the installation of two Ecobee Thermostats. We prepaid Best Buy's Geek Squad to installed them but their electrician was not able to install them properly. The job was abandoned by Geek Squad leaving some HVAC wiring mixed up and at least one wire was not connected properly. Jaleel Porter was courteous and has represented his company extremely well. He came wearing protective mask and shoe coverage. He was knowledgeable about the product that he installed. He was also informative about any general and specific HVAC questions and maintenance issues. Moreover, he was also punctual and cordial in communicating how the service works. He was also patient and helpful in teaching us the settings and operations of the system using our apps. He did not leave the premises until everything was functioning properly. Finally, There were no "surprises" and the price was reasonable and competitive."

FAQs for air conditioning projects in Pleasant Hill, 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.
