"We had Chris replace a decades-old gas furnace and electric water heater, as well as install central air conditioning. We talked to a few professionals in HVAC, and Chris seemed to have encyclopedic knowledge of it all. At a very fair price, Chris spent two days having the old stuff professionally removed, getting the new stuff (AC) wired up, and all the new equipment installed. This was a problem-free project from start to finish, and we would strongly recommend Chris to anyone with similar 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."

"Rodenhisor did an excellent job fixing my broken furnace. Mike R, Nick R, Adam S provided exceptional high quality service (very nice guys). I initially called another HVAC company that came in but there were too many red flags during the discussion. So, I called Rodenhisor for a second opinion. Rodenhiser were on target with what I needed (immediate and long term), provided high quality service (ie on time, within budget, excellent work, cleaned up after repair and even wore booties to protect my beige carpet). I especially liked being able to make special requests such as a customized configuration that allowed for more storage space and done with a good sense for the aesthetics (ie they made it pretty with regards to the wiring, piping, ducting and outlet switch location, etc). They also noticed that it was a struggle for me to open the sliding door to the filter (which gets stuck) so they added an easy to open spring-loaded door just for me. Lastly, it is good to have a large company staff for customers to access for urgent 24/7 calls (minimizing long waits) regarding heating, AC, plumbing, electrical, renovations, etc. It is like a convenient one-stop shopping service that I can keep going to whenever I need something done."

Heating and Air Conditioning FAQs, answered by experts

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak. 

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

Yes, the furnace and AC use the same blower. The blower is located in the base of the furnace and pushes hot air out of the furnace and into the ducts. It also pushes cool air through the home when the air conditioning is on. Even though the furnace and air conditioning work independently of one another, the blower is an essential component for both systems.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.
