"You may have to call a few times, but Jay will always respond. He did a new high end boiler replacement and also installed central air in our home. His price was way under the competitors. Like any contractor, sometimes they are not great at prompt return phone calls and sometimes their schedule gets shifted, but we were very happy with him and have referred him out to several friends."

"This company is great! My very old master bedroom air conditioner failed in the night before a day when Temps were ro be 96 degrees or higher. I called in the am. They were fully booked but promised to watch for jobs that finished early and they did send someone at 2:30 PM. Derek did a fantastic job under very hot Temps . Fit the replacement in and put some caulking in to fill tiny gaps. He even swapped the top rail from the old ac with the newer one as the new ac top rail was not wide enough for the wall opening. He cut a small bit off of the existing stained wood frame to make it fit just right. Derek was meticulously clean. I had a follow up question after Derek left and Steve was thorough and courteous returning my call immediately. I have had this company fix a kitchen cabinet and they were great then as well. I have had two very good experiences and cannot thank them enough for caring enough to get right out to get our ac running so we could sleep in our master bedroom."

"Excellent. I've had Genove install both gas and oil heating systems in my properties, most recently oil. They have also installed central air/hydro air and handle my oil delivery. The techs have always been polite & knowledgable. Their customer service is impeccable. As a landlord/home owner, I couldn't be happier with them handling all my HVAC needs and would recommend them to anyone."

"I recently had a brand new HVAC system installed for both heating and cooling, and I couldn’t be happier with the experience. The team at Comfort Professor was extremely professional from start to finish. They worked efficiently, paid attention to every detail, and left everything spotless when the job was done. The cleanup was perfect, which I really appreciated. Highly recommend them if you’re looking for quality work and a smooth, hassle-free installation!"

"Was give a 2hr window and Tech was a little late. Tech was professional and answered any question I asked. My solution turned out to be fairly simple - Bleed lines and replace valve/air vet. Tech did not have part in truck, called his shop and scheduled appointment for next morning 9am. Tech was again late, due to earlier appointment running long. But once he arrived, was very quick. Paid in the $200 neighborhood for service which could be considered expensive, but that's really a small price to pay for peace of mind for me. One thing -They charge for travel time, which was not stated when I asked for rate. Overall had good experience with Pinnacle and ServiceMagic!"

"Our central air unit died during the hottest days of the year so far. It is a new unit . We called a few places desperate for service and were told it would be a few weeks for most companies to make it out. Called Landrys after finding them on google. A woman called me back less than 20 minutes after first phone call and said they would be out today. Tyler came and was great. Fixed our unit and saved our life! We will be using them in the future for sure. 5 stars for service and their customer service is without a doubt 5 stars as well."

FAQs for air conditioning projects in Weston, 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.
