"Damion was very professional, friendly and thorough. He took the time to explain everything to me and walked me through the entire dryer vent cleaning process before getting started. Once the job was completed, he showed me the results and made sure I was satisfied with the work. I highly recommend Damion and truly appreciate his excellent service. Thank you Damion."

"I had a great experience with Nate. He was extremely knowledgeable about A/C systems and was far more well-versed than many other companies in the area. He took the time to explain everything clearly, answer my questions, and make sure I understood the issue and solution. Nate was also very friendly, professional, and informative throughout the entire visit. I truly appreciated his expertise and excellent customer service. I would highly recommend Nate to anyone needing HVAC service."

Air Conditioning FAQs, answered by experts

For washable or electrostatic air conditioner filters, you can soak and rinse them with water. If you rinse the filter with water, make sure to use a faucet, shower head, or garden hose with a gentle water pressure setting, as strong water pressure could damage the filter.

But for disposable filters, water could ruin the filter, even allowing mold to grow in the filter. Instead, these filters should be replaced.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

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.

Look up your model number online to find additional information. Usually, you can just take a look at the old filter and find the brand name and dimensions to order a new one. When replacing the filter, always check that it’s pointed the right way to match the direction of your airflow. Many filters have arrows on them to help with this step.
