Fast and honest Quality Residential Electrical Service with 38 years of experience at only $75.00/hr. Also provide Commercial Electrical Service.

"Frances is pleasant to talk with and was punctual and responsive. My problem was that he's probably too busy. When I received his invoice, he charged me for the recessed lights that *I* had already purchased and then I had to prove myself by showing him the receipt. He charged me 2x the Home Depot price for Romex (which I had 100 feet of in my garage, ready to go). He put in dimmer switches that didn't match the coloring of my house project (old switches were almond, new switches should have been white) and then indicated he thought I wanted almond color since those were in other places (so were the white!). He should have asked what color I wanted, but didn't and then didn't offer to replace them. This experience left a bad taste in my mouth, I'd not hire him again."

"Huge shout out to the crew at Main Stream Mechanical. Eric came out, reviewed my current system, and gave me his recommendation for replacing my furnace and hot water heater with a new, energy efficient furnace/hot water heater. Brenda, as always, was a pleasure to deal with. Answered all my emails and calls promptly and gave me all the information I needed in a timely manner. She even went out of her way to register my new furnace and provide me with all the information I needed to apply for my rebate! Nick and Marcus did a great job installing my new furnace/hot water heater. Both were very friendly and professional. Nick answered all my questions, gave me a “tutorial” on the emergency shut off procedure for my new furnace, and did a fantastic job re-plumbing all the lines needed for the install. I highly recommend Main Stream Mechanical for all your HVAC needs."

Heating Oil questions, answered by experts

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.

Service costs range from $200 to $1,500, depending on maintenance needs, system age, and labor.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

It’s a better use of energy (and your money) NOT to run an ERV system all the time. Most experts recommend that you cycle your ERV system on and off throughout the year. However, the recommended advice could change based on your climate, the number of people in your home, the size and style of your home, and your heating and cooling system. Contact a local pro for more specific advice.

Costs depend on system age, type, labor, and whether part replacements are necessary.
