"We had a great experience working with Dylan! He was professional and delightful to work with. He had a cancellation the day before our job and reached out to schedule with us within 24 hours of getting an estimate. We would definitely use him again for HVAC and now we know he’s also a licensed plumber, he will be our first choice!"

"I'm not sure how the price compared to others. This was the first time we hired anyone to clean our ducts. We had multiple returns and numerous vents. We decided to go with this business as he communicated well with us and was very accommodating in his schedule. The owner was very thorough in cleaning the ducts and was here for several hours. He explained everything before and after. We will use him again."

"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."

"A great experience for the right price! Excellent communication throughout the entire process. My condo was 5 years old when I bought it and I don’t think the ducts and vents were ever cleaned before. Solid difference in how the systems work now."

"Not easy finding an HVAC company willing to install a gas steam boiler. These guys did it all and did it well, removing the old oil burner and oil tank, installing a Weil McClain boiler including steam piping and hot water, installing gas piping, electrical and plumbing, including all inspections, even leaving me a temporary hot water heater until the furnace installation was completed. They fully accommodated my schedule as well. The town electrical inspector who came after installation was complete confirmed their good reputation."

Heating and Air Conditioning questions, answered by experts

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.
