Customers say: Quick response

"Not exactly sure if this is a Panasonic or Clear Air problem but why should it cost $900 to install a new bathroom light/fan?! It is still not doing exactly what Panasonic claims it should. Very expensive lesson learned. REVISION: It appears the problem is with Panasonic. The description is misleading. Be sure to discuss what you expect from the unit you want to be installed with the electrician BEFORE installing. What the manufacturer says it will do may vary with the circumstances of your particular location. FOLLOW UP, finally reached Panasonic Tech support and it appears Clear Air was correct in their assessment of what the fan/light can do rather than what Panasonic lead me to believe. I made sure the Panasonic tech understood my disappointment. In fact, the Clear Air electrician did a superb job of managing to get the system to perform better than Panasonic seems to have intended. Kudos to Clear Air."

"Gerry was running late for my appointment to clean and inspect two A/C units. He called to let me know . That's a real big plus.... He didn't waste my time. Once he arrived , the work was done quietly , quickly and at what I thought was a fair price. I will call him if I need service in the future."

"Kevin was great. Our Central Air System died during a Heat Wave . When other companies told us they couldnâ t give us an appointment for two weeks, Kevin came the next morning and on a Holiday weekend. He was quick and reasonably priced. We would highly recommend Kevin Russo to anyone looking."

"I found Comfort Air online and reached out to install central AC in my mother's condo. Patrick got back to me promptly, was very receptive in answering all of my mother's questions, and was able to start job within a couple of weeks from first call. The job took two days total, and my mother was impressed from start to finish! I highly recommend Comfort Air."

"We hired this company to install a Rinnai tankless hot water heater and three Fujitsu tuckless mini split heat pumps for our air conditioning and heating needs. We also purchased their two year Preventive Maintenance plan for our furnace. Their workmanship is very professional and all work was completed in accordance to our schedule. Their pricing was very competitive and most reasonable. I especially appreciated the crews sensitivity towards keeping my floors clean while they were going back and forth from inside to outside; all the worksites within our home were left spotless as well as the floors. Thanks to Saul and the men at Revolution..a job well done. See you in the Fall for our PM Contract."

FAQs for air conditioning projects in Sandown, NH

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.
