We are a licensed mechanical contractor in the following categories - hydronic heating & cooling, hvac equipment, ductwork, refrigeration, unlimited heating service and Unlimited cooling service. We also are a licensed electrical contractor with a master electrician on staff. Additional DBA - Perfect Comfort, Inc.

"So I paid over $30,000 for my system about 3 years ago. All they talked about was how great this comprehensive warranty that they gave me was for 10 years and that I wouldn't have to pay for any repairs except regular maintenance... 3 years in and these garbage Tekmar thermostats suck. The one in my master bedroom always resets after a power outage or some event outside of my control. The other ones struggle to pick up wifi or error out randomly. Up until now, they have come out and fixed things. Last visit they charged me $99.00 bucks to configure this piece of crap and didn't tell me there was a charge until after the appointment. Turns out that the warranty is not that great and essentially covers nothing. For that same price I should have gotten a full system tune up. I called them trying to work something out and they flat out said no, but we can come back out and tune up your system for $240.00. The guy literally touched a couple buttons on my thermostat that I don't have access too because it's in some locked tech tools and configured it. I just feel like that should not happen. When you unplug something, you should be able to plug it in and have it work, not reinvent the wheel each time."

Energy Efficiency Auditing questions, answered by experts

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

A good SEER rating is between 15 and 20. However, if you want the best possible efficiency, look for HVAC units with a SEER rating higher than 21. Keep in mind that the SEER rating doesn’t mean that the unit will reach that efficiency all the time, but it does have the capacity to operate at that high of an efficiency level.

As you look for the right soundproofing drywall for you, you’ll likely come across the Sound Transmission Class (STC) rating. This rating measures a building material’s ability to absorb sound. The higher the number, the better the material absorbs rather than reflects sound, reducing noise transmission. The STC rating for drywall doesn’t mean it’s for the panel itself—it refers to the STC rating for the entire wall system, including the soundproofing drywall.

Absolutely! Especially if you have an older home that currently doesn’t have air conditioning where installing ductwork just wouldn't work. No one likes being hot in the warmer months, so if you’re looking to sell your home in the near future, installing a ductless mini-split AC can be a good way to enjoy your home more while you’re in it, boost the return on your sale, and serve as a perk to peak buyers’ interest.

Yes, energy-efficient options such as LEDs and solar-powered lights are available. These alternatives consume less electricity, resulting in lower utility costs. They are also more environmentally friendly due to their reduced carbon footprint and longer lifespan.
