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."

"Lenny and his team were outstanding! Very easy to work with and scheduled us quickly. Didn’t try selling us on anything more than what we needed which was refreshing because we had so many people quote us work that was not needed."

Energy Efficiency Auditing questions, answered by experts

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

Audits include inspecting insulation, HVAC systems, windows, and appliances to identify energy inefficiencies.

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.

Replacing a window frame will improve your home’s energy efficiency if the old frame is cracked or damaged in a way that allows unconditioned air from the outside into your living space or if you upgrade to a more energy-efficient window frame material. Aluminum is the least energy-efficient window frame material, followed by vinyl and wood. Fiberglass and composite frames are the most energy-efficient.
