About Northdial
A small residential heating and cooling company working in six towns across the Kestrel Valley.
Who we are
Northdial looks after the furnaces, air conditioners, heat pumps, mini-splits and thermostats in Kestrel Valley homes. We work on homes only, from older houses with a basement furnace to newer builds with ductless units.
Our tagline is how we like to work: comfort, explained plainly. You hear what we found and what your options are, and you get the estimate in writing before anything changes. We leave the work area tidy when we're done.

How we work
Four habits that apply to every request.
- One lane per request
- Repairs, replacements and seasonal checks each get their own first visit, so they don't get mixed up.
- Explain before we fix
- You hear what we found, in plain language, before anything changes.
- Written estimate first
- No work starts until you've read and approved a written estimate.
- We confirm your visit
- The office calls or emails during office hours to confirm your visit window.
Where we work and when
We serve Kestrel Falls, Quillon Hill, Pellham Crossing, Wrenmoor, Tallowbrook and Corrin Ridge, Monday to Friday, 8:00 a.m. to 5:00 p.m. (sample hours). Visits are by appointment within those hours, with no evening, weekend or emergency visits. Outside these towns? Ask through the contact page.
