"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."

We are a small locally owned home energy company that provides heating oil and propane delivery as well as 24/7/365 Emergency Service to our fuel customers from our team of fully trained and licensed technicians. We also install high efficiency heating equipment to help save you money.

"Their service techs are great but unfortunately that is the only good thing I can say about P Gagnon. Their prices are higher than most other places in the area for both propane and oil, and their office staff are mostly unfriendly (except Debbie). The big problem with P Gagnon is with their sales guy Kent. He is slow to respond to emails and never returns voicemails. He gave me a quote for a small project and after I put down the deposit, he raised the price by more than 40% without anything changing. I asked for a manager to call me to discuss and I never heard from anyone. Still waiting for my deposit to be refunded. I found another local company to do my project instead, and for less than P Gagnon originally quoted me. I strongly recommend you stay away from this company."

Energy Efficiency Auditing questions, answered by experts

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

As you look for the right soundproofing drywall for you, you’ll likely come across the Sound Transmission Class (STC) rating. This rating measures a building material’s ability to absorb sound. The higher the number, the better the material absorbs rather than reflects sound, reducing noise transmission. The STC rating for drywall doesn’t mean it’s for the panel itself—it refers to the STC rating for the entire wall system, including the soundproofing drywall.

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

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably. 

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.
