Complete Furnace Installation Service

Everything Included, Done Right

Your furnace installation includes proper sizing calculations, permit handling, and complete system testing. We don’t cut corners on the details that matter for long-term performance and safety.

Many Medfield homeowners are surprised to learn their old furnace was either too big or too small for their home. Oversized units waste energy and create uneven temperatures. Undersized units run constantly and never quite keep up. We size your new system correctly the first time.

Gas line connections, electrical work, and ductwork modifications are handled by our experienced technicians. Everything is inspected and tested before we leave your home. You’re not dealing with multiple contractors or wondering if something was missed.

How long does a furnace installation typically take in Medfield?

Most furnace installations take between 4-8 hours, depending on your home’s setup and whether any ductwork modifications are needed. If we’re replacing an existing furnace with similar specifications, the job usually moves faster. However, if your home needs gas line work, electrical updates, or significant ductwork changes, it might extend into a second day. We’ll give you a clear timeline upfront so you can plan accordingly. Weather can also be a factor during Massachusetts winters, but we work efficiently to minimize any disruption to your daily routine.

What size furnace do I need for my Medfield home?

Furnace sizing depends on your home’s square footage, insulation quality, ceiling height, and how well your windows and doors seal. A typical 1,500 square foot home in Medfield might need a 60,000-80,000 BTU furnace, but that’s just a rough estimate. Older homes often need larger units due to less efficient insulation and windows. We perform detailed load calculations that account for Massachusetts climate conditions and your specific home’s characteristics. Installing the wrong size furnace leads to higher energy bills, uneven heating, and premature system failure.

Do I need permits for furnace installation in Massachusetts?

Yes, furnace installations in Massachusetts require permits, and we handle all the permit applications and inspections for you. The state requires permits for any gas appliance installation or replacement to ensure safety and code compliance. Local building departments also need to inspect the work, particularly gas line connections and venting systems. Skipping permits might save money upfront, but it creates problems when you sell your home or file insurance claims. We’re familiar with Norfolk County requirements and make sure everything is properly documented and approved.

How do I know if I need a new furnace or just repairs?

If your furnace is over 15 years old and requiring frequent repairs, replacement usually makes more financial sense than continuing to fix it. Other signs include dramatically increased energy bills, uneven heating throughout your home, strange noises, or difficulty maintaining comfortable temperatures. Yellow flames instead of blue flames on gas furnaces indicate a serious safety concern that often means replacement is necessary. We’ll give you an honest assessment of whether repair or replacement makes sense for your situation and budget. Sometimes a simple repair buys you another few years, but other times you’re just throwing money at a system that’s reached the end of its useful life.

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

High-efficiency furnaces (90%+ AFUE rating) extract more heat from the same amount of gas, which means lower monthly energy bills. Standard efficiency units typically run around 80% AFUE. The difference might seem small, but it adds up significantly over a Massachusetts winter. High-efficiency units also have different venting requirements—they use PVC pipes instead of metal chimneys, which can affect installation complexity and cost. While high-efficiency furnaces cost more upfront, the energy savings often pay for the difference within a few years, especially with New England’s heating demands.

What warranty comes with a new furnace installation?

Manufacturer warranties typically cover parts for 10-20 years depending on the brand and model you choose. Heat exchangers, which are the most expensive components, often have longer warranty periods than other parts. Our installation work comes with its own warranty covering labor and workmanship issues. This means if something goes wrong due to installation error, we’ll fix it at no charge. Keep in mind that regular maintenance is usually required to maintain warranty coverage, which is why our Dempsey Comfort Club membership helps protect your investment long-term.
