"Readers should ignore my ratings on work quality and value for the money as the software would not allow me to skip. The technician arrived on time, was informative and professional. He was intent on helping me to get the best results from my system as a new user of this type of unit. I'm not qualified to rate the work quality. It seemed expensive to me, but it's my first experience with a natural gas/air conditioning combination system, so I have no frame of reference. I will use this company again after checking competitive prices."

"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."

"Incredibly professional, always happy to answer questions. Unlike other places that install and you never hear from again, Cam, David, and crew make sure your heat pump stays in tip top shape with yearly cleanings. They even offered to clean a unit that another contractor put in a year prior who refused to come clean it. I got quotes from over 8 different companies for my second heat pump, and Heat Pumps of Maine were a clear step above the rest."

"Josh installed a new water heater, provided us with instructions on proper use and maintenance and has serviced it since. He is honest, thorough, and trustworthy. He also maintains my dad’s HVAC needs too. He has come out for emergency calls too. Suggest things to prevent future additional repair expenses. His prices are reasonable, especially for the personal, friendly customer service and service provided. I would highly recommend Northwoods HVAC."

"Mike called right away to schedule work, and was able to fit me in THE NEXT DAY. Did the work for the AC unit (maintenance/clean up) and as a master electrician, was able to also re-wire us to use the nest thermostat right away, no need to wait for a different technician to come out to do the work. It was HOT up in the attic, so it was REALLY appreciated! Cleaned everything up very nicely after the job was done as well. Looking forward to him coming back to do our next project-he can do it all!"

"They gave a free in-person quote, showed up on time, and stuck to their quoted price. At my request, they waited a few minutes until the electrician showed up, to be sure he wouldn't have any problem and be able to complete the electrical hookup. Recommended."

"Gammon's Heating and Cooling exceeded our expectations! Justin was incredibly helpful in guiding us through the process of replacing our antique steam boiler. He patiently provided three different quotes and never pressured us to choose the most expensive option. The installation team, led by the highly experienced Bill, was fantastic. They arrived on time with a full crew, a great mix of seasoned professionals and eager learners. We even heard Bill sharing his expertise with the younger team members, which was impressive. From start to finish, the professionalism of Gammon's was outstanding. We wholeheartedly recommend them to our family and friends"

FAQs for air conditioning projects in Scarborough, ME

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.
