"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."

"I contacted McGinley & Sons after searching Angie's List for highly rated HVAC specialists. The owner, William McGinley came down quickly to give us an estimate. We were quoted a reasonable price  and booked an appointment to do the job two weeks later. Bill arrived in a timely manner with two other workers and completeted the job in a few hours. He also submitted on our behalf the warranty registration to Goodman Air Conditioning and Heating. We are very pleased with the job they did and would highly recommend McGinley & Sons."

"Job got completed however.... estimated price to perform work initially at $300/hr is absurd and that was negotiated. Everyone online stated job was 2hrs max - quote was 4hrs. Ideally independent plumbers and HVAC folks would be associated with home advisor as I had thought they would be happy to get $150/hr. Not sure what home advisor cut is for the referral or if it was heritage general pricing but I will think twice about making a call in the future. I have no issue paying a fair price for work - but double or triple fair will not happen at my home."

"I discovered I needed a new furnace and also a new toilet in our main floor bathroom of our house the week before Thanksgiving. I used Angi to quickly get a few company estimates and decided to go with Sanford Temperature Control/High Ground. I was very happy I did. Zach Lewis, the project manager contacted me, reviewed his estimate with me, scheduled all the work to be completed the day before Thanksgiving and followed along to be sure it was finished on schedule. He and his team did an excellent job. I highly recommend them. Thank you Sanford Temperature Control/High Ground!"

Heating and Air Conditioning FAQs, answered by experts

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.

While all portable AC units will collect moisture as part of their cooling and dehumidifying process, whether and how often you need to drain them depends on what kind of unit you have and the natural humidity levels where you live. For example, if you live in a very dry area and have a self-evaporating unit, you may not need to drain your portable AC very often at all. Some units may automatically drain collected moisture out the window through their exhaust vent.

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.

An AC inspection costs anywhere from $75 to $200, while a full HVAC system inspection that includes your furnace ranges from $200 to $450. While there's a cost to a home AC inspection, it can save you hundreds or thousands in the long run by catching problems, avoiding breaks, and saving you money on your utility bills.

If your central AC is not blowing cold air, you should try resetting the system. Many systems have a reset button. Make sure your thermostat is off, then turn off the circuit breaker that powers your AC. Hold the reset button for three to five seconds, then turn the circuit back on. Set your thermostat to cool and choose a temperature cooler than the room. Your system should turn on quickly.
