"I found FLG Home Performance thru Angie online read his reviews, and while going thru other referred reviews. I received a call from Frankie who answered All my questions took his time to ask me questions and so I hired him. Frankie came to the house the next morning and worked on my Oil Steam Burning Boiler for hrs, you can barely find anyone that can work on these anymore. He cleaned it out, checked every radiator in the home, explained everything to me, clean the bathroom, his work, And is extremely fair in pricing."

Find out why by letting us do the same for you today!

"Getting a tune up appointment which they claim pays for the contract fee is impossible to get if they even keep it. In the 12 years I was with them maybe 4 tune ups happened as most of the time they are booked 6-12 months out. That’s how backup they are on this pre Covid Second I put my deliveries on hold and they sent me a cancellation fee. A few that was never disclosed in the email I agreed to (see attachment) after disputing it and saying they never disclosed it they sent me the bill again now with late fees. After 12 years and 10’s of thousands of dollars this is how they treat a long standing customer. Run but not to Petro as that’s the same company. Go to Slomins instead."

Energy Efficiency Auditing questions, answered by experts

Installing weather stripping or upgrading to insulated panels can improve efficiency.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

Yes, with features like LED lighting and variable speed controls for efficiency.

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

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.
