Your local HVAC in Dover
When the heat or the AC quits in Dover, it tends to happen at the worst time and the worst price. Dover is one of the oldest settlements in New Hampshire, on the Cocheco River, and I head up that way for the right jobs. I am Tanner, the licensed owner of TJM Climate Control, and I do the work myself, so the person who quotes your Dover job is the one who runs the lines and tests it before leaving.
Within Strafford County, Dover is squarely in the territory I cover from Kingston. It is an easy run out toward the seacoast from Kingston. Neighbors like Kingston, Salem and Derry are the same run, the same clean work, and the same owner standing behind it.

Common questions about HVAC in Dover
Do you really service Dover, NH?
Yes. Dover is in Strafford County, part of the roughly 50 mile radius I cover from my Kingston shop. I am out this way often, so a Dover call is routine work for me, not an out-of-the-way trip.
How much does a ductless mini split or a new furnace cost in Dover?
It depends on the home, the rooms you want covered, and which rebates apply, and that spread is real money. So I come out to your Dover home, run a real load calculation, and put your exact number in writing for free, with the rebates already counted.
Do heat pumps really work in Dover winters?
They do. A properly sized cold-climate heat pump keeps a New Hampshire home at 70 when it is below zero outside. Sizing is where comfort is won or lost, so I run a load calculation on every install instead of guessing, and we can keep your furnace as backup if you want the extra peace of mind.
What HVAC rebates can I get in Dover?
In New Hampshire, NHSaves pays about $250 per ton on a qualifying heat pump, and more when you are replacing electric resistance heat. The New England Heat Pump Accelerator adds $650 per outdoor unit on top. I will tell you honestly what your Dover install qualifies for. Note that the federal 25C tax credit ended on December 31, 2025, so any page still advertising it is out of date.
Who actually does the work on my Dover job?
I do. TJM Climate Control is owner-run, so the licensed person who quotes your Dover install is the same one who runs the lines and tests the system before leaving. That hands-on approach is how I have kept zero callbacks on my installs.
