"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."

"Bill called me first thing in the morning (7:30) after I sent out a request very late the night before. I had one others HVAC contracter make two trips to my home but could not figure out the problem? Bill had two of his tecknisions come out that morning but the problem still eluded them. The next day Bill came to my house and within 10 minutes he had it figured out. He explained exactly what the problem was and got my furnace up and running at 100%. He called back that night to check with me and make sure. Everything was OK."

"Alex was great! Courteous, responsive, prompt, friendly, but more importantly, honest. The job couldn’t be done because of the structure of my HVAC system, yet Alex (and Vinny) took the time to explain the problem and tried, albeit unsuccessfully, to seek an alternative solution. I have such respect for his honesty. I highly recommend using this company, for that reason alone."

"Bruce really listened to how I answered his questions and designed a natural-gas fueled steam boiler system that met all the requirements with the expansion potential I requested. During pre-installation logistics and the day of installation, Bruce and his crew were on-time, courteous and professional. Their work demonstrated the benefits of hiring a fully credentialed company, skilled and experienced at their craft. They completed their work in one very long day so that I could avoid a night without heat during a stretch of very cold January days. I trust Williams & Assoc. and would hire them for additional work in my home as needed"

"The technician, Steve, called me 25 minutes prior to his arrival. He was extremely knowledgeable about my gas fireplace. He vacuumed all areas. He informed me of the condition of the components. I was prepared to ask him a handful of questions that he was able to answer. My fireplace works very well and I strongly recommend using the Chimney Experts."

Heating and Air Conditioning questions, answered by experts

Dry mode positively impacts indoor air quality by reducing excess moisture, which stops the growth of mold and mildew. By maintaining optimal humidity levels, dry mode creates a less hospitable environment for allergens and airborne pathogens, improving overall air quality. However, it's essential to ensure proper ventilation to prevent stale air accumulation.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

After a while, dust, dirt, and other debris accumulates on an AC unit's coils and filters, making it less efficient and spreading allergens and other air pollutants throughout your home. Cleaning your AC unit will keep it running efficiently, minimizing future breakdowns and improving your indoor air quality.

To diagnose a bad HVAC or AC damper, assess the airflow from your vents. For a manual damper, close it, run your system, and check for airflow. If air is still coming through the vents, the damper is likely faulty and needs repair or replacement. For an automatic damper, turn on your HVAC system and monitor the airflow and room temperature. Signs of a problem include low airflow, a room that won't maintain its set temperature, or a drafty feeling. If you suspect a faulty automatic damper, you may need to hire a professional for repairs.

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.
