"CRS Heating and Cooling did a great job of diagnosing the problem, explaining to us what needed to be done, and then completing the job. They scheduled the job immediately and were on time on the appointed date. It is nice to have our air conditioning functioning as it should now. We would not hesitate in calling them again and would recommend them to any of our neighbors in need of the expertise."

"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."

"Thank you ZACK for your professionalism taking pictures of the work you did cleaning the filters of my A/C system outside. This is the first time anyone showed me pictures of the work they did. You were kind and explained to me when was the best time to have my heating system checked and when to call to make an appt. for the fall. You were knowledgeable, caring, and I felt safe with you. What a GREAT employee to represent Palmer Gas. Also, Thank you Customer Service Rep. MICHELLE L. - you answered all questions asked of you in a friendly and professional way. That is why I stay with Palmer Gas. Heidi Ricci"

"Eric was awesome! Replied to my initial inquiry right away. He fixed my bathroom ceiling fan and replaced some outlets in my bathroom. He checked everything to make sure it was safe. Super friendly and I felt very comfortable. Very reasonable with pricing as well. I would highly recommend Angell Electric! Thank you"

"I hired TCC three weeks ago to install a heat pump mini-split systems for my 4 BR home. Their quote was competitive, their install went as planned, and the technicians were super knowledgeable and worked hard to do it right. I am thrilled with the results. I have recommended them to family already and TCC will get more business."

"Scheduling was easy and they came the same day. Kyle who serviced my water heater was efficient and pleasant plus he had a mask which I was pleased to see and I told him while he worked on his own on the heater I didn't mind if he took off the mask......he was very respectful of my wishes and always put his mask on while coming to talk to me. I was very pleased with the efficiency all around from this company and would use them again. I know that I rated the "value for my money a little low" but that was because I did feel it was a little more than I would expect for the job that had to be done. However, I was so pleased that they came and were efficient and easy to deal with that I could overlook that and would certainly use them again. Thank you Kyle and Proactive Comfort!!!"

FAQs for air conditioning projects in Barnstead, 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.
