"Dylan is very reliable and knowledgeable. He has provided plumbing services many times for us and I wouldn't use anyone but him. The service is exceptional and pricing is extremely fair. I highly recommend Venture Mechanical for any plumbing, heating, or air conditioning needs that you may have."

"On the day that the heat pump is installed, request that Paul or Daniel be there at the end of the installation to go over all the details on how to operate the complicated thermostat. Paul and Daniel will answer all questions, but those who install the pump do not handle thermostat questions. And the maker of this thermostat, like the makers of all modern thermostats, does not provide a manual or a clear explanation on-line. This lack of manual and on-line instructions is exceptionally frustrating, which is why staff like Paul and Daniel are essential on the day of installation."

"Our Burnham boiler has been giving us issues this winter after just purchasing the new house over the summer. We've come home a number of times to no heat and a cold house, but had luckily managed to YouTube our way into figuring out fixes. This time unfortunately we couldn't figure it out and needed to search for an HVAC contractor. Green Energy was the first company I could even get to answer my call. At 9am Melissa was able to set me up with a day of appointment, Terry was at our house by 1pm. Since this boiler type is still new to us, Terry was great with explaining the workings of the equipment, and just some general tips for upkeep. It ended up being a simple fix with a loose relay, however I would of never been able to figure that out on my own. Terry ended up also doing a general servicing and cleaning of the unit, which they recommend annually to help the equipment last longer (we're positive the previous owners never did it). I would highly recommend Terry, he was knowledgeable and overall good guy. We also plan to sign up for their annual membership program and use Green Energy moving forward."

"I highly recommend Pro Heating & Cooling . The owner recognized my need for the timely installation of a new boiler system, when other companies callously gave me a window of 3-4 weeks in the middle of freezing weather. To aid the process, the owner also took care of the paperwork needed to apply for a loan, and rebates. This was a complex job, but this company has the teams/expertise necessary to complete the work efficiently."

"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

"The tech was on time, and he constantly put on shoe covers before coming through the house. He checked over my system and worked up a quote for 2 different plans of action, from lowest price to highest. He explained each issue to be addressed and there was no pressure as to what degree of intervention to take. I ended up having all of the recommended work performed, as it had been some time since I had the unit serviced. All of the work was done effectively and neatly. I am a facilities manager and know good work from bad, and this work was excellent..I would definitely hire them again. Also; the people who answer the phone and schedule service were extremely friendly and helpful."

"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 Canton, 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.
