"Repairs were excellent and thorough "even well documented". The tech found units low on coolant. He identified and repaired multiple refrigerant leak points. I have dealt with many HVAC contractors over the years and Freedom Air Mechanical is one of the best. I highly recommend."

"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!"

"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."

"The water pump for my over 16 year old central air conditioner stopped working and, as a result, I discovered water in my basement. I searched Home Advisor for a company to fix the problemand selected NSHEC based on customer reviews. I was able to schedule a service call online for that afternoon, then had a few questions about the issue and repair that I wanted answered before having them come out. I called and left a message, they returned my call within minutes, discussed my issue, explained what the possible issue was, how long it would take to fix it as well as the estimated cost of the repair. The technician, I believe his name is Jake, arrived on time and had the part on his truck. He quickly made the repair, explained what he did and that it is common for the these pumps to eventually stop working. If that should happen again in the future, the new pump was wired to shut down the ac and getting water in the basement would now be averted. The final cost was a few dollars more than the phone estimate, service was very prompt, the technician knowledgeable, quick, very pleasant and answered all of my questions before and after the repair. I wouldn't hesitate to call NSHEC again should another issue arise in the future."

FAQs for air conditioning projects in Nottingham, 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.
