"Exceedingly STELLAR work; BEYOND professional decorum elicited by the company’s OWNER AND staff MEMBERS (specifically the technicians that performed the installation). Overall, we HIGHLY recommend this company to neighbors, family, friends, coworkers & even strangers in our community that may be in need of any HVAC or others services for their homes and/or businesses. Financially, they were on par with our anticipated costs for the work we needed done. FAST, QUALITY WORK that we’d NEVER hesitate calling on again for any future needs that this EXCEPTIONAL, ‘5-star worthy’ company provides! Thank you especially to Ron, Carlos and Brandan… we truly enjoyed meeting you and the pleasure of your company while you worked diligently in our home was all ours. Perhaps this review seems “over the top”or contrived, but we truly wanted to reward this company properly with a review that sufficiently and congruently matched their “talk with the walk” behavior. As you (a co-consumer) know there are so few these days that that elicit good, old- fashioned business ethics. We want you to know this was honestly a job TRULY well done!"

"I was in the market for a ductless AC system for my house. With a project like this, it is wise to get multiple estimates and do your research. Cawiamca came right away to provide me with an estimate, came in at the best price, and could start the work the soonest. They installed three head units in the bedrooms and one in my living area. They left no mess in my home and placed drop cloths at the entrance. They went the extra mile to make sure I was happy with my AC system and stand behind their products and labor. I would highly recommend them."

"I feel fortunate to have been able to meet Chris and have him fix my HVAC issues. He was prompt, excellent at communicating, and also is a great listener. The cost of my service wasn't low due to what was needed but it was more affordable than other quotes I'd recieved; some of the others who had spoken to me on the phone were indicating rates that were 50% higher than what Chris charged for the same exact product! I'll gladly hire him for future work. I've already given his number to others with HVAC needs."

"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."

"Excellent experience. Arrived when he said he would, quickly assessed the problems, did a quality job with both dryer vent repairs and a thorough cleaning. He did all that at a very fair price. Highly recommend him for HVAC and dryer vent cleaning and repairs."

"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"

Heating and Air Conditioning FAQs, answered by experts

Yes, a dehumidifier and air conditioner can be used simultaneously in a home. A dehumidifier can bolster an air conditioner’s efficiency. Typically, a dehumidifier is used when the air conditioner alone cannot keep a home’s humidity levels at a comfortable indoor humidity level, which should, ideally, be between 30% and 50%.

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

An HVAC unit, like a furnace, air conditioner, or heat pump, produces warm or hot air. The air ducts serve as the passages to help heat or cool air from the HVAC unit flow through the home. Air ducts are just one part of the overall HVAC system.

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.
