"On time, professional, easy to work with, willing to trouble-shoot and think outside the box to determine the cause of the furnace problem. Had suggestions for further upkeep and service, should the time come. Replaced parts that should have been changed and/or replaced and cleaned by former company, but were neglected for the last three years. Was reassuring that the entire furnace did not need to be replaced!"

"I chose them because they had the highest number ( and score) of reviews, but after the service was provided I believe those reviews were fabricated. I am a new home owner and decided to try your services. I did not know much about duct or vent cleaning but after what I saw yesterday I decided to do some research online and that is when I realized I did not receive the services I thought I was paying for. Only 1 technician came with a small shop vacuum and a brush, and he was not able to do most of the work because. 1. We had Fibreglass ducts and he said his equipment was not suitable to clean this type of duct and that it would damage it. So he only "vacuumed" the area that his arms could get to, and did not examine the vent for damage or recommend any way to clean or fix the fiberglass. 2. He did not want to take the vent covers off the ceiling because he said he did not want to damage the sheetrock, so I'm not sure how he cleaned them. I think he only sprayed air into and around the vent 3. He didn't have any air filters with him, so I had to go out and try to buy them. They did not have the size I needed so I spent 1 hr driving around looking for them and could not see what he was doing at home. 4. They did not seal any of the vents nor did they have a negative pressure machine. He did not hook up to the main vent and told me he accessed it with a brush through an intake, which means that they did not fully take out all the dust from the main feeder. At first I was ok with his explanation, fine but then after doing research I realized that all he did was stick a brush in the room vent but did not seal the whole system, nor did he take off and clean the main duct. 5. He said he cleaned the dryer vent from Inside and Outside but I did not see any signs of him going outside as it was raining and he would have had to get the machine wet. 6. He had no other equipment other than a shop vacuum with a 4 inch hose. I'm not sure how deep he was able to get with that into the dryer vent. I really feel as if the work performed was not done correctly, and my ignorance was partly to blame. This company certainly did not have the right equipment to do the job and they didn't even use the correct procedure to seal the system to create a vacuum. This was definitely more of a $300 dollar job at most and not $600 dollars like they charged me."

FAQs for air conditioning projects in Willimantic, CT

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.
