Signs It’s Time to Replace Your Heating System

Replacing a system before it fails lets you pick the right equipment on your schedule instead of taking whatever is available during a cold snap. These are the usual signs.

• Age past 15 years for a furnace, or past 20 for many boilers, puts equipment near the end of its expected life.
• Repeated repairs in the last two or three seasons often add up to a large share of the cost of a new system.
• Gas bills rising without a change in how you use the home can mean the system is losing efficiency.
• Uneven heat between floors or rooms may point to a system that was sized wrong from the start.
• A cracked heat exchanger in a furnace is a safety problem, and replacement is usually the right call.

How We Size and Install a New Heating System

Sizing matters more than most homeowners expect. A furnace that is too large heats the house in short bursts, cycles constantly and wears out early, while one that is too small runs nonstop on the coldest nights. Our comfort advisors measure the home and run a load calculation that accounts for square footage, insulation, windows, ceiling heights, and air leakage. We also check the ductwork, since a new furnace connected to undersized or leaking ducts will not deliver the comfort or efficiency it is rated for.

From there, you get options instead of a single quote. Depending on the home, that could mean a high-efficiency condensing furnace, a modulating boiler for a home with radiators or in-floor heat, or a heat pump paired with a gas furnace for backup. Each option comes with an upfront price, so you can compare efficiency, comfort and long-term operating cost.

On installation day, the crew protects floors and work areas, removes the old equipment and installs the new system to manufacturer specifications. That includes gas connections, venting, condensate drainage, electrical work and thermostat setup. Before the crew leaves, the system is fired up and tested, airflow is checked and you get a walkthrough of the controls. Most furnace replacements are finished in a single day.

Furnace Replacement

Most Caledonia homes are heated by gas furnaces. We install standard and high-efficiency models and update venting when a home moves from a chimney-vented unit to a condensing furnace with PVC venting.

Boiler Replacement

Older homes around Racine and Milwaukee often still run on cast iron boilers. A modern high-efficiency boiler can cut gas use while keeping the radiators or baseboard you already have.

Heat Pump Installation

Cold-climate heat pumps can handle much of the heating season and also provide air conditioning. Paired with a furnace, they switch to gas when outdoor temperatures drop too low.
