What we do

Heat, delivered and maintained.

Four ways we keep your home comfortable — and your highlighted service below is the one that matters most this time of year.

24/7 emergency service

No heat at 2am? A real technician answers, every time — nights, weekends, holidays, blizzards.

Automatic oil delivery

Our delivery software learns your usage and tops you off before you'd ever run low. Will-call available too.

Mitsubishi mini-splits

Diamond Elite installation of ductless heat pumps — efficient heating and cooling, big Mass Save rebates.

Budget plans

Spread your heating costs evenly across the year. No surprise bills when the first cold delivery lands.

Service plans

Plan A or Plan B — both pay for themselves.

You don't need a plan to get service from us. But a single emergency repair usually costs more than a year of coverage, and both plans include a cleaning worth $200–$250.

Plan A · full coverage
Total Comfort
The most protection against costly heating repairs. Parts and labor, covered.
  • Annual cleaning & tune-up included
  • Covered labor on repairs
  • Covered parts on the protection list
  • Priority emergency response
Includes a complimentary cleaning — often a $200–$250 value on its own.
Plan B · labor coverage
Peace of Mind
The same protection on labor, with parts billed separately. A lighter-cost middle ground.
  • Annual cleaning & tune-up included
  • Covered labor on repairs
  • Parts billed at cost
  • Priority emergency response
Also includes the complimentary cleaning. Call for the full part-coverage list and pricing.

Meet Dug.

Every delivery truck has a co-pilot. Dug has been riding shotgun since he was a puppy, supervising oil drops, greeting customers at the office, and making absolutely sure no one leaves without a treat. He's the reason half our customers wave when the truck pulls up.

"It's cold out there. Don't skip your delivery — I'm watching." — Dug
