"Chris Scotti was the only one willing to come out on a late Sunday afternoon! My house was almost 90 degrees inside, I have few screened windows and I depend on the central air to work! Brand new A/C unit purchased 3months ago, that would not work and the company I purchased it from would not even come out to help me! Chris showed up and fixed the problem! He is very knowledgeable and explains everything!!! Over heating in a house is just as dangerous as freezing! Companies that install A/C units should have staff/technicians on stand by for emergencies!! Chris was great!!!"

"Bill was amazing from the start. Within an hour of submitting an inquiry through home advisor he immediately contacted me. Not only did he have questions but also provided minor troubleshooting steps to ensure it wasn't anything small causing my forced air system from consistently power cycling. Highly recommended."

"John was awesome. He was professional, friendly and very knowledgeable. I had previously had some repairs done to my central air system by another company. That result was not up to my expectations. John from Quiet Corners came out, accurately diagnosed my problem, and came out within a week to install a new condenser. We now have cool air in our house. They also work with American Home Shield, which covered most of the cost of the repairs. Great Experience!!! I highly recommend them.."

"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."

"Encon is a great company! I had an ant problem and needed an exterminator right away. Based on good reviews, I called Encon in a panic and Debbie fit me in right away. Ryan came out to the house and talked with my husband. He explained the problem and sprayed around the foundation and inside where the ants seemed to be coming from. That night we had more ants then ever! I called in the morning and spoke to Debbie and told her what happened. She talked me off the ledge and explained how the nest was disturbed and that was normal. I was also happy with the cost. They were very reasonable. I will always call Encon for my pest control needs!"

"I could not be more pleased with this company or this service. I found them here on AL and with a rebate, it was a great deal. When I called, the woman who answered was extremely polite and helpful and took the time to go over the entire audit process with me (she wasn't rushed as some receptionists are). They sent an email to confirm the date and time.
When the team arrived, they were on time and each of them introduced themselves by name to me before coming into my house. They were all very polite and courteous. The leader (I can't remember his name) gave me an overview of the process and explained things as they went. Basically, they simulate high winds around the house and then monitor for where leaks are. My house is relatively new and has no basement, so it was already pretty efficient, but there were some major leaks by the front door and attic door, which they sealed on the spot. They also showed me that I could hold my hand over any electrical socket, even ones on interior walls, and feel the "wind"--which means air was leaking out those! So I plugged them all with those little socket protectors. The guys also took me into the attic and showed me some leaks, and fixed them--and fixed the attic door by adding a little latch to help it stay closed. All in all, they reduced the amount of air getting into my house by 500 (I forget the units). It was clear they didn't just make up this number--they showed me the number after the first test and then after the second test (when they had treated the problem areas).
I also got a few free CFLs and LEDs, and bought 3 more LEDs since they were at a great price. They left some rebates with me, although all my appliances are new so I didn't need anything. 
When they left, they each said goodbye and were very professional until the end. They were respectful in my home and asked before opening any closets or doors, etc. I felt very safe with them here, which is not always the case when people are in your home working. I think the price is a fantastic one, especially with the AL rebate that was on when I scheduled. I feel I got my money's worth. My husband and I had tried to plug some leaks ourselves, but we didn't really know what we were doing and we had no way to measure if we were really helping anything. This audit gave me hard numbers to look at and I was impressed that they did the fixes on-site (included in the price--for instance, they plugged a whole around my front door frame by installing a clear plastic barrier). It was a great deal and a great experience. Highly recommend!
Bonus--when we resell this house in a few years, I will definitely list that we got a professional energy audit performed on it and that it's very efficient. Definitely a selling point!

"Jim was very helpful and personable to work with.  I had recently moved to the Huntsville area and was unable to connect my wireless printer.   There were also some things going on with my laptop that made me suspect a virus had somehow gotten on to it, it was running more slowly than usual, and I wasn't happy with the Win7 configuration I had done when I bought the computer.  Jim came in and assessed the problems and we agreed on a time for him to take the laptop and reinstall the OS.  He was able to get the wireless connection to work as well.  He took the computer on a Friday evening and returned it Sunday evening in prime condition. 
A few weeks later I  got an error message while reinstalling my accounting software so I called Jim.  He talked me through the problem over the phone and I was able to get the program installed so I could use the program.
Jim is great to work with, his pricing is very fair, he is prompt and reliable.  I will definitely use his services again.

FAQs for air conditioning projects in Plainfield, 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.
