"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."

"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

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.
