When Your HVAC Goes Down, Every Hour Counts

A broken air conditioner in a New England heatwave, or a furnace that quits in January, is more than an inconvenience. It can be a real safety issue, especially for elderly family members or young children.

Yellow Dog's HVAC technicians are trained to respond fast. We drive fully stocked trucks so we can diagnose and fix most problems on the first visit, without the delay of ordering parts or scheduling a second trip. Because we answer the phone 24/7, you can reach a real person the moment something goes wrong.

We work on all major HVAC brands and system types, including central AC, mini splits, furnaces, and heat pumps. We will give you an honest diagnosis and upfront price before we do anything.

Prevent Breakdowns With Yellow Dog's Annual Maintenance Plan

10/10. Got here early, fixed it within 15 mins, could not have been nicer. Upfront with the price, had everything they needed, got the job done smoothly.

For urgent HVAC issues, we aim to get to you the same day you call. Our phones are answered 24/7 by real people. Call us at 617-362-3338 and we will tell you our earliest available time.

HVAC repair costs vary depending on the problem: refrigerant issues, compressor problems, electrical failures, and thermostat issues all have different price points. We will diagnose your system and give you a clear, upfront price before doing any work. There are no surprise charges on your invoice.

A good rule of thumb: if your system is over 10 to 15 years old and the repair cost exceeds 50% of a new system's price, replacement often makes more financial sense. We will give you honest advice either way. And if you do need a new system, we will walk you through your options including any Mass Save rebates you qualify for.

Our trucks are stocked to handle the vast majority of common repairs on the spot. In the rare case we need to order a part, we will let you know the timeline and return as quickly as possible.

Yes. We service and repair all major brands including Mitsubishi, Fujitsu, Trane, American Standard, Carrier, Lennox, Goodman, Bryant, and more.

Yes, we handle light commercial HVAC repair and maintenance in addition to residential service. Call us to discuss your building's needs.
