"Sila installed a new Lennox HVAC system 2 years ago and when there was a leak today they showed up within hours! Not like some places that would have many excuses and complain about Fri being too busy. Their Tech Calverton is a special tech, knowledgeable, polite and willing to go the extra mile. Not only did he fix the leaking problem he took his time to adjust dampers to ensure all rooms are toasty! This has always been a problem for us and not fixed until now. It takes a patient problem solving tech to make a happy customer! A special thanks to the service manager ,Doug Bines , who always seems to help when needed."

"I wanted to clean a second floor dryer vent hose that was loaded solid with lint. It was worse than I thought! Packed solid! It became evident that this was a messy and dangerous situation as it was a fire hazard. Through Angi I found Everclean and the co. was a perfect fit. HVAC companies don’t do dryer vents. Justin from Everclean was awesome and got the problem straightened out. He even discovered the dryer vent had become disconnected from outside dryer vent door! I can’t fit through the narrow attic hatchway as my shoulders are a bit too wide, so I depended on Justin. Finally, everything is buttoned up, and our clothes now dry in half the time. Cost was moderate and was money well invested. Dryer vent fire danger is now negligible compared to before. Along with neighbor hatred danger. I would hire Everclean again if needed again."

"Satisfied customer. I'm pleased with the services offered by Wtech22 in July 2024, in Stamford, CT. Wilson resolved my unique central ac problem with a few solutions. He called me back the same day to address my needs. He was quick to diagnose the problem. He was knowledgeable and explained everything throughly. His team of 4 removed the old central ac unit and replaced with a new one all in one day. He was willing to work with a customer, his professionalism and courteous earned him and his team my five star rating!! Wilson is also very easy to talk to, making the experience more enjoyable. They ended up working late to finish the job, we provided dinner for the team to show our appreciation. With all that said I would recommend Wtech22 to my friends and family. You need to talk to Wtech22 first before other HVAC companies, and you won’t be disappointed!"

Heating and Air Conditioning questions, answered by experts

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.

Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line—the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation.
