"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 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."

"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."

Heating and Air Conditioning questions, answered by experts

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.
