"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

"He started great, but went down hill. 5 months to install a new heating system after being told it was 5-6 weeks.I was told he had no idea when he could finish because he started a 92 unit condominium project. On another project they installed an HVAC system with no control board. Lied to continuously about dates. We paid in advance for the work and found out afterward that he fired half the staff (I now know why.) Rather than be upfront about the issues he was facing we told lies. Very frustrating and found Devin to talk like an excon. Say one thing and do another with a very straight face."

Energy Efficiency Auditing questions, answered by experts

If you install LED bulbs, they will use much less energy than incandescent bulbs. LED light strips also use less power. Battery-operated puck lights use no electricity at all, but you will need to replace the batteries as needed. They are beneficial if your power goes out, too, as they will remain on as a light source. 

Smart glass doesn’t use a lot of electricity, and you can expect a standard window to add between $1 and $2 per year to your electric bills. Smart glass is proof that energy-efficient windows work. Although your smart windows may consume a little energy to operate, they can save enough energy to offset the costs. If you’re concerned about the minimal bump to your electricity consumption, you can opt for smart tint, which doesn’t require electricity to work.

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.

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.

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.
