"Highly advise not to use them for any installation jobs. Sloppy work, incorrect with regulator placement and double billed after another experienced technician did the job. Even the experienced technician did a half assed job reconnecting an exhaust vent that he decided to remove to run the gas line which did not need to be removed. cannot get ahold of customer service to discuss or dispute the service bill which then has my oil and gas deliveries on hold. I prepaid for the gas delivery while under dispute and am being double billed. I may just find a more reliable local person as this big time company with small time feelis simply not working out."

Energy Efficiency Auditing questions, answered by experts

Keep the unit full but not overloaded, ensure door seals are tight, set correct temperatures, and avoid frequent door openings. Position the appliance away from heat sources for optimal performance.

Typically, triple-pane windows made with krypton gas filling are the most energy efficient. A window’s frame, glass, design, and installation all affect its energy efficiency. These windows, in particular, are designed highly effectively in terms of their ability to insulate.

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.

Some types of electric fireplaces use more electricity than others. Models that produce 1,500 watts will have more of an effect on your heating bill than 750-watt models. 

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.

HVAC systems use the most household electricity. This major and essential system is responsible for heating and cooling your home all year round. Since they operate for a significant amount during the day, it consumes more energy than other appliances.
