What Proper Installation Actually Gets You

Your heating bills drop because the system runs efficiently instead of working overtime to heat your home. No more cold spots in the bedrooms or having to crank the thermostat just to feel comfortable.

You stop worrying about breakdowns in the middle of winter. A properly installed furnace runs quietly, heats evenly, and gives you years of reliable service without constant repair calls.

The air quality improves too. New systems filter better and don’t circulate dust and allergens like older units that have been patched together over the years.

How long does a furnace installation typically take?

Most furnace installations take 4-8 hours depending on your home’s setup and whether we need to modify ductwork or electrical connections. Straightforward replacements where the new furnace fits the existing space usually finish in half a day. More complex installations that require ductwork changes, electrical upgrades, or permit inspections can take a full day or require a second visit. We’ll give you a realistic timeline during our initial assessment so you can plan accordingly.

What size furnace do I need for my home?

Furnace sizing depends on your home’s square footage, insulation levels, window types, ceiling height, and local climate conditions. Many homeowners assume they need the same size as their old unit, but that’s often wrong. Oversized furnaces cycle on and off too frequently, wasting energy and creating uneven heating. Undersized units run constantly and never quite keep up. We perform detailed load calculations to determine the exact BTU requirements for your specific home, ensuring optimal comfort and efficiency.

Should I replace my furnace before it completely breaks down?

Yes, planned replacement is almost always better than emergency replacement. When you replace a furnace that’s still limping along, you have time to research options, compare prices, and schedule installation at your convenience. Emergency replacements often cost more, limit your equipment choices, and leave you without heat while waiting for service. If your furnace is over 15 years old, needs frequent repairs, or your heating bills keep climbing, it’s time to start planning for replacement rather than waiting for complete failure.

Do you handle gas line connections and electrical work?

Yes, we handle all the gas line connections, electrical work, and ductwork modifications needed for your furnace installation. Our technicians are properly licensed and experienced with the gas and electrical requirements for residential heating systems. We also pull necessary permits and coordinate inspections when required. This means you work with one company for the complete installation instead of coordinating multiple contractors. Everything is done safely and up to local codes.

What's the difference between standard and high-efficiency furnaces?

Standard efficiency furnaces operate at around 80% efficiency, meaning 20% of the fuel energy goes up the chimney as waste heat. High-efficiency furnaces operate at 90-98% efficiency by capturing and using that waste heat. High-efficiency units cost more upfront but can significantly reduce your monthly heating bills, especially in our Massachusetts climate where furnaces run for months. The payback period depends on your current heating costs and usage patterns. We can calculate potential savings based on your specific situation.

What warranty comes with a new furnace installation?

New furnaces typically come with manufacturer warranties covering parts for 5-20 years depending on the brand and model. Heat exchangers often have longer warranty periods since they’re the most critical component. Our installation work is also warranted separately to ensure everything is installed correctly and functions properly. We’ll explain all warranty terms and help you register your equipment with the manufacturer. Keep in mind that regular maintenance is usually required to maintain warranty coverage, which is why many customers join our Dempsey Comfort Club for ongoing service.
