Keep Your Home Warm All Winter

Furnace installation and heating services in Lonsdale for year-round comfort and reliable performance.

When temperatures drop in Lonsdale, your furnace becomes one of the most important systems in your home. You rely on it every day to keep your family warm, and when it stops working efficiently or breaks down entirely, the cold air in your home makes it hard to sleep, work, or feel comfortable. Minn Mechanical Contractors LLC installs and services furnaces, boilers, and unit heaters designed to meet the specific heating demands of homes in Lonsdale.

A furnace installation involves removing your old heating unit, positioning the new system in your mechanical room or basement, connecting it to your ductwork and fuel source, and testing it under load to confirm proper operation. If your home uses a boiler instead of forced air, the process includes connecting the unit to your radiators or in-floor heating lines and adjusting water pressure and temperature settings. Unit heaters are installed in garages, workshops, or open spaces where central heating does not reach, providing focused warmth where you need it most.

What happens during a heating system installation

When your new furnace arrives at your home in Lonsdale, the installation crew disconnects your old unit from the gas line or electrical supply, removes it from the space, and prepares the area for the new system. They measure clearances around the unit to meet code requirements, position the furnace on a level base, and connect the supply and return ducts using sheet metal fittings and screws. Gas connections are pressure-tested for leaks, and electrical wiring is run to the thermostat and control board.

After the furnace is installed, you will notice warmer air coming from your vents within minutes of startup, and your home will reach your set temperature faster than it did with your old system. The blower runs more quietly, and cold spots in distant rooms disappear as airflow balances throughout the house.

Boiler installations follow a similar process but involve connecting the unit to your home's hydronic piping, filling the system with water, bleeding air from radiators, and adjusting the aquastat to maintain consistent water temperature. Unit heaters are mounted on walls or ceilings using brackets, wired directly to a dedicated circuit, and angled to direct warm air toward the floor. The work typically takes one full day for a standard furnace and may require an additional half day if ductwork modifications are needed.

What homeowners in Lonsdale often ask us

Homeowners in Lonsdale often have similar questions before committing to a furnace or heating system installation, and the answers depend on your home's layout, fuel availability, and current ductwork condition.

How long does a furnace installation take?
Most furnace installations in Lonsdale take between six and eight hours, depending on whether ductwork needs modification or if the gas line requires rerouting. If you are replacing a furnace in the same location with similar dimensions, the work is usually completed in one day.
What is the difference between a furnace and a boiler?
A furnace heats air and distributes it through ducts and vents, while a boiler heats water and sends it through pipes to radiators or in-floor tubing. Your home's existing heating distribution system determines which type you need.
When should I replace my furnace instead of repairing it?
If your furnace is over fifteen years old, requires frequent repairs, or no longer heats your home evenly, replacement is usually more cost-effective than continuing to fix an aging system. Minn Mechanical Contractors LLC can assess your current unit and help you decide.
What size furnace do I need for my home?
Furnace size is determined by your home's square footage, insulation quality, window count, and ceiling height. An oversized furnace cycles on and off too often, while an undersized unit runs constantly without reaching your set temperature.
Can I install a unit heater in my garage?
Yes, unit heaters are designed for garages, workshops, and other spaces without ductwork. They mount on the wall or ceiling, connect to gas or electric power, and provide direct heat to the area you use most.

When your furnace stops keeping up with the cold or your boiler begins leaking around the base, waiting only makes the problem worse and leaves your home vulnerable during the coldest weeks of the year.
