"It was Saturday afternoon. When I saw water spreading on my basement floor, I called Nutmeg. Within 15 minutes, I got a call back from a tech. He said he could be here within 20 minutes, and he DID. He cleared the drain from the evaporation pan. All is well, and I was satisfied with the weekend charge. Super service. Have used Nutmeg in the past for my HVAC work, and will always use them in the future."

"I hired Albana Roofing to replace the Soffit and Fascia on my house. It's a family-owned company and everyone was super nice and very knowledgable. They did a great job, arriving at 8:00 am each day to work a full day. They even worked on Saturday to get the job done quicker. I recommend them and would hire them again in the future."

"We had previously worked with Energy Monster on a Mass Save audit and then adding insulation to our house. This time, we had the guys from Energy Monster back again to perform an electrical upgrade on our house (100 to 200 amps) and then install five ductless mini-splits for more efficient heating/cooling than our ancient terrible radiators. Despite dealing with a lot of obstacles -- a heat delay due to several 90 degree days and then tons of rain that prevented them from doing the outside work on the days they wanted -- the whole team was professional and efficient and made the most of the time when the weather finally cooperated! (Plus, my dog loved the whole crew and the loved him back.) It has been such a pleasure to work with Energy Monster as we turn our house into the energy efficient home of our dreams. Thank you!! We can't wait for Energy Monster to come back later this summer to install solar panels next!"

Energy Efficiency Auditing questions, answered by experts

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.

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.

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.

A couple of the best ways to find a reputable energy auditor is by determining whether they are HEP-certified by the Building Performance Institute (BPI). This certification will help you narrow down your list of professionals to the most qualified pros with the most relevant experience. 

You can also choose from the Department of Energy’s certified list of energy auditors or Angi’s contractor licensing tool to find pros in your area.

Costs depend on pipe length, accessibility, and whether additional services are required.
