"Freedom Air Mechanical did an amazing job with replacing my boiler. I had 5-6 people come out to give me opinions and Craig was the only one that really took his time to help me find the best boiler for my home. He was very responsive, answer all my questions and concerns, and very importantly I knew he was honest. Out of all the potentials companies I considered, Freedom Air was the only one that gave me options and tried to help me save where I could. I would recommend Freedom Air Mechanical to my family and friends all day."

"We have been a Palmer customer for 6 years. The front office and the technicians has always been great to work with. We have been using their AC and Heating Service Plan and on automatic oil and propane fill for years and we have never had an issue. My most recent experience was today for the AC Service Plan. The technician (David) was very polite, experienced, knowledgeable and respectful of our time and home. It’s always a great experience to have maintenance conducted in you home and have the technicians give you expert advice on your heating and AC system. Our AC system is well over 25 years old and still running strong thanks to Palmer. I continue to be impressed with Palmer and will remain a customer for the foreseeable future!"

"My Mitsubishi Mini split A/C was not cooling properly even after a tune-up by another tech company in the spring. Kevin came by the day after I called and fixed the issue quickly. Now the unit is like brand new. I would recommend and will have this business tune my units up from now on."

"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 Epping, 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.
