Furnace Installation Process

Here's Exactly What Happens

First, we’ll assess your current system and your home’s heating needs. This isn’t a quick glance—we calculate the proper size furnace for your square footage, insulation levels, and local climate conditions. Getting this right prevents future problems and verifies peak efficiency.

Next, we handle all permits and scheduling. You shouldn’t have to chase down paperwork or worry about code compliance. We coordinate with local inspectors and make sure everything meets Massachusetts building requirements.

Installation day means protecting your home while we work. We use drop cloths, remove the old equipment safely, and install your new furnace with precision. Before we leave, we test everything thoroughly and show you how your new system operates. You’ll have our direct contact information and warranty details in hand.

Complete Furnace Installation Service

Everything You Need, Nothing You Don't

Your furnace installation includes proper system sizing, professional installation, all necessary permits, and thorough testing. We don’t cut corners on ductwork connections, gas line work, or electrical connections—these details determine whether your system runs efficiently for years or gives you problems from day one.

We also handle the cleanup and old equipment removal. You won’t have an old furnace sitting in your basement for weeks waiting for someone to haul it away. When we’re done, your basement will look better than when we started.

Every installation comes with manufacturer warranty coverage and our commitment to stand behind our work. If something isn’t right, we come back and fix it. Our Dempsey Comfort Club members get priority scheduling for any future maintenance or service needs.

Most furnace installations in Avon take 4-8 hours, depending on your home’s setup and whether we need to modify existing ductwork or gas lines. Straightforward replacements where the new furnace connects to existing systems typically finish in a single day. More difficult installations involving ductwork changes or electrical upgrades might require a second day. We’ll give you an accurate timeline after assessing your specific situation, and we always clean up completely before leaving your home.
Furnace sizing depends on your home’s square footage, insulation levels, window types, and ceiling heights—not just the size of your old unit. Many older homes in Avon have oversized furnaces that waste energy and don’t heat evenly. We perform detailed load calculations to determine the right BTU output for your specific home. This creates optimum efficiency and comfort while preventing the short cycling that leads to premature equipment failure and uneven temperatures.
Yes, we obtain all required permits and coordinate inspections with Avon building officials. Massachusetts requires permits for furnace installations, and we handle this paperwork as part of our service. We’re familiar with local code requirements and inspection schedules, so you don’t have to navigate the permit process yourself. All our installations meet or exceed state and local building codes, and we’ll provide you with copies of all permit documentation for your records.
Absolutely. Many homes in Norfolk County have ductwork that needs modification or repair during furnace installation. We assess your existing ducts and recommend necessary improvements to confirm proper airflow and efficiency. Such improvements might include sealing leaky connections, adding return air ducts, or resizing supply ducts to match your new furnace capacity. We handle both the furnace installation and ductwork modifications in one coordinated project, so you get optimal performance from your complete heating system.
Your new furnace comes with manufacturer warranty coverage, and we stand behind our installation work completely. If you experience any issues related to our installation, we return promptly to resolve them at no charge. Our Dempsey Comfort Club members get priority scheduling for any service needs. We also provide you with direct contact information and detailed warranty documentation, so you know exactly what’s covered and how to reach us if questions arise about your new heating system.
Modern high-efficiency furnaces typically reduce heating costs by 20-30% compared to units that are 10-15 years old. Your actual savings depend on your current furnace efficiency, home insulation, and heating habits. For an average Avon home, this often means $300-800 in annual savings during our heating season. The savings start immediately with your first heating bill and continue for the life of your system. We can provide more specific estimates based on your current energy usage and the efficiency rating of your new furnace.
