Still have questions?
Call any hour, any day - a live person answers and we can book your visit right then.
Do you offer emergency HVAC service?
Yes. We are available 24/7 for emergency heating and cooling service. Call 781-539-7241 any hour, any day. A live person answers the phone and we will get a technician out to you as quickly as possible.
Which towns do you serve?
We are based in Woburn and serve Boston and the surrounding suburbs, including Cambridge, Somerville, Medford, Burlington, Lexington, Winchester, Stoneham, Reading, Wakefield, Arlington, Waltham, Newton, Malden and Brookline.
Do you provide free estimates?
Yes. We give free estimates on all new installations. We work with integrity, giving straightforward advice and a pricing guide so you know what to expect at each stage of the process.
How often should my system be serviced?
We recommend annual preventive maintenance: a cooling tune-up in the spring and a heating tune-up in the fall. Regular service keeps efficiency high, lowers your utility bills and catches operating deficiencies before they turn into breakdowns.
Do you work on both homes and businesses?
We do. Our residential team handles heating repair, A/C repair, full replacements and system additions. Our commercial team services rooftop units, controls, cooling towers and the rest of your building equipment.
Can I rent temporary heating or cooling equipment?
Yes. We provide temporary heating and cooling rentals (chillers, spot coolers and heaters on demand) for planned projects, equipment failures or events when your permanent system is out of service.
Do you handle plumbing as well as HVAC?
We do. Alongside heating and cooling, our team takes care of leaks, water heaters, piping repairs and preventive plumbing maintenance for homes and businesses.
Are your repairs covered by a warranty?
Most repairs come with a one-year warranty, and we stand behind our work with a money-back guarantee. We focus on long-term results rather than quick fixes.
