Nine months of heat, and winters near zero
Blaine needs a furnace from September through May. That is nine months out of the year, and it includes stretches where the low sits around 9°F. A furnace here does not get an off season to rest and recover, it runs most of the year and has to hold up on the coldest nights without hesitation.
Most homes in the area heat with gas, and any furnace installed new has to meet the federal minimum of 80 percent AFUE. That is the floor, not a feature. Beyond that, the choice is about a unit sized and installed to keep up with nine months of demand and the nights that hit single digits.
- 9 months
- September through May, your furnace is on duty
- 9°F
- the average winter night it heats against
- 83%
- of homes here heat with gas, so most furnaces here burn gas
- 80% AFUE
- the federal minimum any new unit must meet

A high-efficiency gas furnace would save about $100 a year to run in Anoka County compared with a gas furnace.

Minnesota has no state license for HVAC contractors.
There is no state license or registration behind the contractor who installs your furnace. Minnesota does not test HVAC contractors, does not keep a state record of who they are, and does not require them to register before doing home heating work. Whatever protection exists here comes from somewhere other than a state credential.
For this job, that protection is mostly local. In most cities and counties, replacing a furnace needs a permit from the local building office and an inspection once the work is done. Anoka County runs heavily on gas furnaces, with 83.3% of homes heating that way, so a permit and inspection are the check this county relies on in place of a state license.

- What size furnace does my house need?
- There is no single answer without a load calculation on your actual house. A contractor figures this by looking at your square footage, insulation, windows, and ceiling height, not by matching the size of the furnace you have now. Putting in one that is too big or too small wastes fuel and wears out faster, so it is worth having someone measure rather than guess. With winter lows here averaging 9°F, getting the size right matters more than in places where the furnace barely has to work.
- How do I know it's time to replace my furnace?
- Watch for rising repair calls, uneven heat between rooms, and a furnace that is old enough that parts are getting harder to find. If you are heating from September through May like most homes here, nine months a year of runtime adds up faster than it would somewhere milder. A furnace that keeps breaking down mid-winter, when nights are averaging near zero, is one you cannot afford to have quit on you. A contractor can look at its condition and tell you whether repair still makes sense or whether you are past that point.
- Is a high-efficiency furnace worth it?
- It depends on how much you heat and how long you plan to stay in the house. Since 2015, even standard non-weatherized gas furnaces have to hit 80 percent AFUE, so the real comparison is between that baseline and the higher-efficiency models above it. With heat running nine months of the year here, a furnace that uses less gas per degree of heat adds up over a full season in a way it would not somewhere with a short winter. A contractor can walk you through the actual efficiency ratings available and what fits your house.
