"Donny and his team are the best, They installed a new HVAC system for us in the Fall and made some updates to our other systems. When we needed help with a fan noise issue they came out quickly and fixed the issue with really creative and innovative ways of problem solving. Incredible."

"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 turned to finding a dryer vent contractor on this website when I was unsuccessful in finding one through Google. Either the company didn t call back or didn t show up. My current HVAC contractor stopped cleaning dryer vents. When I began the search, it was very late at night. Y&M Airduct Service phoned me the very next morning. They were rated very well and see why. They are honest and explain everything in detail. There were a few things I knew that needed to be addressed, such as the attachment to the hose behind the dryer and the vent that had been broken to the outside of the house. Everything has been fixed and/or replaced at a very reasonable rate. Not only was this experience very positive but have decided to not renew my contract with my exiting company that I ve had for over 10 years. I will be having Y&M perform all of my HVAC needs. If you decide to hire Y&M Airduct Service, you will have everything done right the first time. No hidden agenda, no hassle and piece of mind knowing one less item is taken care of."

"I recently had Vent Worx service all the vents in my condo . The service provider was on time , very efficient, explained all the work they were doing and was extremely careful to ensure that Everything was returned to it original location . I was very pleased with this service and they also sanitized the entire unit when they completed all their work. I certainly would recommend this company for their services."

"Seems the basic cleaning does not work well for my situation. Noticed lots of loose dust ball around opening of vents right after service is done. The promotion price is good. But feel the work to replace missing dryer cap is expensive. Technicians are helpful and knowledgeable."

Heating and Air Conditioning FAQs, answered by experts

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.

It depends on the size of the space you’re cooling down. If you’re looking for the most affordable way to cool an entire house over a long period of time, then central air will be more cost-effective. But when it comes to cooling down a couple of rooms or one floor, a window unit may be the cheaper option, with both a lower cost to install and less energy used to run.

Yes, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.
