When Should I Replace My Furnace?
Most furnaces last around 15–20 years. If yours is nearing that range, constantly breaking down, or leaving certain rooms colder than others, replacement is usually the more cost-effective option.
In our experience, furnaces installed in the early 2000s and 2010s tend to lose efficiency around the 15-year mark, even with regular maintenance. Parts become harder to source, and repair costs start adding up fast.
What we typically recommend at this stage is a full system evaluation before committing to another repair. If a major component like the heat exchanger or blower motor needs replacing, putting that money toward a new unit often makes more sense in the long run.

Common Types of Furnaces We Install
The right furnace depends on your property, budget, fuel availability, and other local factors. Below are some common types of furnaces we install:
- Natural gas furnaces are a popular choice for homes with an existing gas line. They heat quickly, cost less to run than electric models, and carry higher efficiency ratings.
- Electric furnaces are a good fit for homes without gas service or where running a gas line isn't practical. Electric units cost less upfront and need less maintenance, although monthly operating costs can run higher.
- Propane furnaces are an excellent alternative for rural properties off the main gas grid. They deliver hotter air output than standard electric models while maintaining high energy efficiency.

What Size Furnace Do I Need?
Furnace size isn't about square footage alone. Insulation levels, windows, and ductwork all affect how much heat your home needs. A furnace that’s too small will run constantly and struggle to keep up during cold snaps. A unit that's too large will short-cycle, wear out faster, and leave some rooms overheated while others stay cold.
Instead of guessing based on your old unit's size, our technicians perform Manual J load calculations for every installation. This step makes a big difference in comfort and monthly costs by accounting for your property’s layout and construction, so the furnace we install matches how your house holds and loses heat.
Choosing an AFUE Rating for Your New Furnace
AFUE stands for Annual Fuel Utilization Efficiency. It measures how much of the fuel your furnace burns turns into heat for your home versus what's lost through the flue. An 80% AFUE furnace turns 80 cents of every fuel dollar into heat. A 95%+ AFUE furnace pushes that closer to 95 cents.
Most homeowners fall into one of two camps: those staying long-term who want the lower operating costs of a high-efficiency unit, and those prioritizing a lower upfront price for a rental or short-term stay. The right choice depends on your budget and plans for the property.
We install industry-leading brands across a range of AFUE ratings, all backed by solid warranties. By comparing the numbers side by side, you can see the real trade-off between initial cost and operational savings, so you can make an informed choice for your comfort and energy goals.
