Heat Pump Installation Process

Here's How We Handle Your Installation

First, we evaluate your home’s heating and cooling needs. This means looking at square footage, insulation, windows, and existing ductwork to determine the right system size and type.

Next, we handle the installation itself. This includes removing your old equipment, installing the new indoor and outdoor units, connecting refrigerant lines, and testing everything to make sure it’s running properly.

Finally, we walk you through your new system’s operation and maintenance needs. You’ll know how to use your new equipment efficiently and when to call for service. We also set you up with our Dempsey Comfort Club for ongoing maintenance and priority service.

Most heat pump installations take one full day, though some larger or more complex jobs might require two days. The timeline depends on factors like whether we’re replacing existing equipment or installing a completely new system, the accessibility of installation areas, and any electrical work needed. We’ll give you a clear timeline during our initial evaluation so you know what to expect. We work efficiently to minimize disruption to your daily routine while ensuring everything is installed correctly.
Heat pump sizing depends on your home’s square footage, insulation levels, window efficiency, ceiling height, and local climate conditions. A system that’s too small won’t keep you comfortable, while an oversized system will cycle on and off too frequently, reducing efficiency and comfort. We perform a detailed load calculation during our evaluation to determine the right size for your specific home. This isn’t guesswork—it’s based on industry standards and our experience with Norfolk County homes.
Modern heat pumps are designed to work efficiently in Massachusetts winters, even when temperatures drop below freezing. Today’s cold-climate heat pumps can provide effective heating down to temperatures well below what we typically see in Norfolk County. Many newer models work efficiently even at 5°F or lower. We recommend heat pumps specifically rated for New England climates and can explain how your system will perform throughout our heating season.
In most cases, existing ductwork can be used for your new heat pump installation, though we’ll inspect it first to ensure it’s in good condition and properly sized. Sometimes we need to make modifications or repairs to optimize airflow for your new system. If your home doesn’t have existing ductwork, we can discuss ductless mini-split options that don’t require ducts at all. We’ll evaluate your specific situation and explain any ductwork needs during our initial assessment.
Energy savings depend on what you’re replacing and how you currently heat and cool your home. Homeowners replacing older furnaces and air conditioners often see 30-50% reductions in heating and cooling costs. Heat pumps are significantly more efficient than electric baseboard heating or oil-fired systems. We can provide estimates based on your current energy usage and the efficiency ratings of the equipment we recommend for your home.
Heat pumps need regular filter changes, annual professional maintenance, and occasional cleaning of the outdoor unit. Basic maintenance includes changing filters every 1-3 months and keeping the outdoor unit clear of debris, snow, and vegetation. Professional maintenance should be done annually and includes checking refrigerant levels, cleaning coils, inspecting electrical connections, and testing system performance. Our Dempsey Comfort Club makes this easy with scheduled maintenance visits and priority service when you need repairs.
