"Under new Ownership! I have known the owners personally for 20+ years and can attest that they are amazingly generous, kind, and selfless people. Last month, the HVAC went out in one of my rental homes. I was out of town, and Excel flawlessly completed the project on time and without any complications. My tenants were completely satisfied with the level of professionalism they demonstrated, and I found their pricing to be very reasonable. I'm switching my HVAC company to Excel because of my inside knowledge of who the owners are and the high level of reliability and integrity the possess. You can't go wrong with Excel!"

"Mr. Ashcom did a thorough check of my heat pump system, changing the filter, making adjustments, and diagnosed a small  problem part that needed immediate fixing, so he took care of that as well. One issue I was having had to do with a noisy start and David actually flipped a "quiet" switch that my previous HVAC man had not done, which made the unit much quieter. David was willing to answer questions without a problem; he mentioned things to watch for, since my system is a little older; he did not seem to be looking for repairs that weren't necessary, which I appreciated. 
Also, I lived a bit outside of David Ashcom's usual service area, but he came anyway and he didn't have a bad attitude about the extra travel time.  I liked his professional manner and would happily recommend him as an honest contractor.  If he's willing to come back next year, I'll gladly hire him!!

Heating and Air Conditioning questions, answered by experts

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

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

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

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.
