How Your Installation Actually Works

First, we assess your current system and your home’s heating needs. This isn’t just measuring square footage—we look at insulation, ductwork condition, and how your family actually uses the space.

Next, we recommend the right size and type of furnace for your specific situation. Oversized units waste energy and create comfort problems. Undersized units can’t keep up during cold snaps. We get it right.

Installation day means removing your old equipment safely, installing the new furnace according to manufacturer specs and local codes, and testing everything thoroughly. We clean up completely and walk you through your new system’s operation before we leave. You’ll know exactly how everything works and what to expect from your new heating system.

Most furnace installations take 4-8 hours, depending on your specific situation. If we’re replacing a similar system with good existing connections, it’s usually on the shorter end. If we need to modify gas lines, upgrade electrical connections, or make ductwork adjustments, it takes longer. We’ll give you a realistic timeframe during our initial assessment so you can plan accordingly. The key is doing it right rather than rushing through important safety and performance details.
Furnace sizing depends on your home’s square footage, insulation levels, window types, ceiling height, and local climate conditions. Many older homes in Cohasset have oversized furnaces that cycle on and off too frequently, wasting energy and creating uneven temperatures. We perform a proper load calculation to determine the right BTU output for your specific home. This ensures efficient operation and consistent comfort throughout your living space.
In Cohasset, gas furnaces are typically the most cost-effective choice for heating. Natural gas costs less than electricity for heating, and gas furnaces heat your home faster during cold weather. If you already have gas service to your home, a gas furnace installation is usually the smart choice. Electric furnaces make sense in homes without existing gas lines where the cost of running new gas service is prohibitive. We’ll evaluate your specific situation and explain the long-term operating costs for each option.
Yes, we handle all required permits and inspections for your furnace installation. Cohasset requires permits for HVAC installations, and we’re familiar with local code requirements and inspection processes. This procedure confirms your installation meets all safety standards and won’t cause issues if you sell your home later. We manage the paperwork and scheduling with local inspectors so you don’t have to.
Your new furnace comes with manufacturer warranty coverage, and we stand behind our installation work.

We maintain detailed records of every installation in our system, so we know exactly what equipment you have and how it was installed if service is ever needed.
Yes, we perform furnace installations year-round, including during winter months. We understand that heating system failures don’t wait for convenient timing. During winter installations, we work efficiently to minimize the time your home is without heat. In most cases, we can complete the installation and have your new system running the same day. For emergency situations, we prioritize getting you back up and running as quickly as possible while still assuring proper installation procedures.
