"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 highly recommend Justin from County Line Plumbing and Heating. He recently replaced a hot water heater at a rental property I manage and did a fantastic job from start to finish. He’s prompt, reliable, and always responsive—especially during emergencies. His customer service is excellent, communication is clear, and the work is done right the first time. A true professional and someone I trust with my properties and my own home."

Heating and Air Conditioning questions, answered by experts

To find a reputable HVAC company, start by researching providers in your area. Look for companies with mostly positive online reviews and check the Better Business Bureau’s website for customer complaints. Next, verify their credentials. Rule out any companies that aren’t licensed, as this is a requirement in some states and municipalities, and confirm they are insured. Once you have a shortlist, contact each professional to ask key questions: How many years of experience do you have? Do you hold any third-party certifications? Do you have experience working on my specific type of HVAC system or brand? Can you provide references? What is your per-hour pricing? Do you offer maintenance contracts for ongoing savings? Do you provide a warranty for your work?

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

It’s never a good idea to run your AC without a filter, even just for a night. The filter defends your HVAC system from the dust, dirt, debris, and other grime in your home. Without a filter, those contaminants are more likely to get inside your system and potentially damage it.
