"Overall working with Dan was a great experience. I had hired Dan to perform an energy audit. I had the attic insulated to R-38, but one room was still rather chilly. I needed the audit to pinpoint the issue. Now I know each area of infiltration and how to address each. Finally, Dan spotted an issue with my hot water heater. I'm especially grateful of this last point. Dan obviously knows his stuff and has the experience to back it up. I highly recommend him for energy audits."

"We had a dirt floor crawl space and a concrete floor crawl space in our home. Both spaces were very cold and nasty looking. We wanted a solution that would help us become more energy efficient and at the same time create some additional storage space. We initially met with a Perma Seal consultant who walked us through what could be done. He suggested we start by installing insulation in both spaces-which we did through another vendor-and then Perma Seal would install their vinyl liner into the space. Long story short the liners are great-the spaces are bright, clean and dry and we now have a lot more storage space."

Why the importance of family owned? Why does it matter? It matters because it means we are long term, and we care at a level that is hard for large corporations to understand. We are an HVAC contractor who will be here tomorrow, and the next day. Not a fly-by-night dealer gone when you need us most. \nFamily-owned also ensures you will experience a level of customer service that is unique to family-owned companies. We understand the importance of reliable and efficient air conditioning, heating and indoor air quality products for our own homes and office, and we know that the same is important to you. For this reason we provide our customers with the latest in heating and air conditioning technology - products that we would trust in our own home.

"The removal and install went as planned, with the 10" of foam completely changing the energy efficiency of my 100 year old house. Unfortunately, there was damage to one of the ceilings as a result of the staff in the attic, but the Eco Tec repaired the damage the next business day. Not only did Eco Tec provide and outstanding value, I was very impressed how it immediately resolved the minor repair and followed up to make sure it was completed to my satisfaction. Special thanks to Stacy in the office and Josh, one of the company owners."

Energy Efficiency Auditing FAQs, answered by experts

No, it isn’t necessary to have energy-efficient windows. However, if you care about your energy bill and making your windows more energy efficient, fixing any heat, UV, or air transfer issues is an excellent way to lower your bills and keep your house cooler in the summer and warmer in the winter.

A blower door test shouldn’t take more than an hour, and most can be completed in less than 30 minutes. Expect the test to take longer once you start searching for leaks with thermal imaging or want to include sealing such leaks in the time estimate. The test doesn’t take much time and can’t be rushed, but it will take longer in large homes or those with many air leaks.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

String lights require electricity, but not an excessive amount, especially when compared to other lighting fixtures. LED rope lights, for instance, consume around one watt per foot. Running six or seven light strings simultaneously should only cost you around $10 to $15 each month. You can save even more money by remembering to turn off your lights during daylight hours. 

Fireplaces can theoretically help you save on heating bills if you lower the temperature throughout the rest of your home and heat only a single room that you occupy using the fireplace. However, in most cases, homeowners won’t save any money on heating bills. Gas and electric fireplace inserts could actually lead to a spike in your respective energy bills if you use them frequently, and if you don’t keep up with chimney maintenance and repairs, your traditional masonry fireplace could actually be a source of heat loss in the winter.
