"Airco is a great family-owned and operated business, very fair and knowledgeable. They replaced our forced air central heating system (oil) in a day, and were quick to respond and get to work despite how busy things were during the January cold-spell. I would highly recommend for your heating and cooling needs!"

"Diagnosis and repair were straightforward and the talented Mike, who has done other great work for us on our ACs, had a replacement pump in his truck. Swapped over in under an hour. Cost of the repair was quite high, mainly due to very high price they charged for the pump. A Taco pump that I could buy for $175 was priced on this repair at more than $500. I get that it was an urgent situation and I’m happy to pay reasonably for the response but that mark-up bothered me. I called the office, had a long talk with the owner; sadly, she offered no consideration at all. Yes, it’s hard to find and keep skilled techs, but now seems that most HVAC firms have a business model like a car dealer’s service dept, far more corporate, less flexible or customer-considerate."

"Paul found the most suitable system for our smallish cottage house, and he and Daniel were invaluable in explaining how a modern thermostat works to get the right settings. Once the purchase was made, the company quickly installed the heat pump. The company also helps with the rebate forms. During the recent cold nights, the heat pump has worked flawlessly. We are very satisfied with the product."

"My 30 year old boiler, with much fanfare chose to conk out, leaving me without heat as an impending snow storm was in the forecast. After getting outrageous quotes from another HVACs for a new boiler, I lucked out in finding Pro Heating. When Sean learned I was without heat, he gathered his A team and within a couple of days (other companies were saying it would be weeks)installed a high efficiency boiler that was less costly and is far superior to the less efficient boilers that the other companies quoted. Sean and his team are incredibly knowledgeable and professional. I highly recommend Pro Heating and Cooling, and have done so already to friends and family!"

"My central air system went down in the middle of a heat wave and virtually every HVAC repair service that I called told me that they weren t taking new clients and couldn t help me. I contacted Chris through home advisor and he agreed to help me out. He promptly came to my house, identified my problem, and ordered parts. When the parts arrived he immediately came back and installed them and I was up and running. Chris identified and fixed my problem and the entire process took only 2 days. On top of that, the price was more than reasonable and Chris is a super nice guy. I highly recommend Chris because he is a skilled and professional technician."

FAQs for air conditioning projects in Roxbury, MA

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.
