Everything Included in Your Installation

Your furnace installation includes professional sizing calculations to match your home’s heating load. We don’t guess – we measure square footage, insulation levels, and window efficiency to recommend the right capacity furnace for optimal performance.

All gas line connections, electrical work, and venting modifications are handled by our licensed technicians. We ensure proper clearances around your new furnace and test all safety systems before leaving your home.

You receive manufacturer warranties on equipment plus our labor warranty on installation work. We also include thermostat programming, system walkthrough, and maintenance schedule recommendations.

Most furnace installations in Mansfield homes take 4-6 hours from start to finish. This includes removing your old furnace, installing the new unit, connecting gas lines and electrical, and testing all systems. If we need to modify existing ductwork or run new gas lines, the installation might extend to a full day. We’ll give you an accurate timeframe during our initial assessment so you can plan accordingly. Emergency installations often get same-day scheduling when your heating system fails during cold weather.
Furnace sizing depends on your home’s square footage, insulation quality, ceiling height, and window efficiency – not just the size of your old unit. Many Mansfield homes built in the 1970s-80s have oversized furnaces that waste energy and create uneven heating. We perform load calculations to determine the right BTU capacity for your specific home. A properly sized furnace runs longer cycles for better humidity control and more even temperatures, while an oversized unit short-cycles and wastes energy on frequent starts and stops.
Yes, we handle all permit requirements for furnace installations in Mansfield and throughout Bristol County. Massachusetts requires permits for gas furnace installations, and we’re familiar with local building codes and inspection requirements. We pull the necessary permits, schedule inspections, and ensure your installation meets all safety and efficiency standards. This protects you from liability issues and ensures your homeowner’s insurance coverage remains valid. Some homeowners try to skip permits to save money, but this creates problems when selling your home or filing insurance claims.
We handle complete removal and disposal of your old furnace as part of our installation service. This includes disconnecting gas lines, electrical connections, and ductwork safely before removing the unit from your basement or utility room. We dispose of the old furnace according to Massachusetts environmental regulations and clean up all debris from the installation area. You don’t need to coordinate separate removal services or worry about proper disposal methods. The installation area is left clean and ready for your new furnace operation.
Yes, we provide emergency furnace installation services throughout Bristol County, including same-day installation when possible. Winter furnace failures can’t wait for convenient scheduling, especially during January and February cold snaps. We stock common furnace models and maintain emergency installation crews for urgent situations. While emergency installations may cost slightly more due to after-hours labor, we focus on getting your heat restored quickly and safely. Our goal is having your new furnace operational within 24 hours of your emergency call.
Your new furnace installation includes manufacturer equipment warranties ranging from 5-20 years depending on the model and components, plus our labor warranty on installation work. High-efficiency furnaces typically carry longer warranty periods on heat exchangers and major components. We also warranty our installation labor for the first year, covering any issues related to our workmanship. Many customers join our Dempsey Comfort Club for ongoing maintenance that keeps manufacturer warranties valid and extends equipment life. We handle all warranty claims and service directly – you’re not dealing with multiple companies for equipment and installation issues.
