Your home stays comfortable without the constant worry about whether your system will keep up. No more dreading those extreme New England weather days because you’re not sure if your heating or cooling will handle it.

When you install a heat pump properly, you’re looking at consistent temperatures throughout your house. Not those hot and cold spots that make certain rooms unbearable. Your energy bills drop because the system isn’t working overtime to compensate for poor installation or wrong sizing.

You get one system that handles both heating and cooling efficiently. That means fewer moving parts to break down and fewer service calls. Most importantly, you get the peace of mind that comes from knowing it was installed by people who understand how these systems work in Massachusetts weather.

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, existing ductwork, and how your house actually uses energy. No guessing or using generic charts that don’t account for your specific situation.

Next, we size the system correctly. This is critical because an oversized heat pump will cycle on and off constantly, wasting energy and wearing out components. An undersized system will run constantly and never keep you comfortable. We calculate the load properly so your system runs efficiently.

Installation day involves removing your old equipment safely, installing the new heat pump with proper refrigerant lines and electrical connections, and testing everything thoroughly. We check airflow, verify electrical connections, and make sure the system operates correctly in both heating and cooling modes.

After installation, we walk you through how your new system works and answer any questions. You get information about maintenance requirements and how to get the most efficiency from your investment.

Most heat pump installations take one full day, but this depends on your specific situation. If we’re replacing an existing system with similar ductwork and electrical setup, we can usually complete everything in 6-8 hours. However, if we need to run new electrical lines, modify ductwork, or deal with unexpected complications, it might extend into a second day. We’ll give you a realistic timeline upfront based on what we find during our initial assessment. The goal is to get your system running properly, not to rush through and leave you with problems later.
Yes, modern heat pumps are designed to work efficiently in cold climates like ours. Today’s cold-climate heat pumps can provide effective heating even when temperatures drop to -10°F or lower. They use advanced technology that extracts heat from outside air even in very cold conditions. However, proper sizing and installation are critical for cold-weather performance. An undersized system will struggle when temperatures drop, while a properly sized system will keep you comfortable throughout winter. We size systems specifically for New England weather patterns, not generic calculations that might work in milder climates.
Heat pump sizing depends on several factors including your home’s square footage, insulation levels, window types, ceiling height, and how well your house holds temperature. We perform a detailed load calculation that accounts for all these variables rather than using simple square footage rules. A properly sized heat pump should run consistently rather than cycling on and off frequently. Oversized systems waste energy and don’t control humidity well, while undersized systems can’t maintain comfortable temperatures during extreme weather. The calculation process takes about 30 minutes and ensures you get a system that matches your home’s actual heating and cooling needs.
In most cases, yes. A heat pump provides both heating and cooling, so it can replace both your furnace and air conditioner with one efficient system. This simplifies your HVAC setup and typically reduces energy costs since you’re running one efficient system instead of two separate ones. However, we need to evaluate your existing ductwork to make sure it’s compatible and properly sized for heat pump operation. Sometimes minor ductwork modifications are needed to optimize airflow. We’ll assess your current setup and let you know exactly what’s required to make the conversion work effectively in your home.
Energy savings depend on what you’re replacing and how efficiently your current system operates. Homeowners typically see 30-50% reduction in heating and cooling costs when replacing older furnaces and air conditioners with modern heat pumps. However, your actual savings depend on factors like your current system’s efficiency, how well your home is insulated, and your usage patterns. Heat pumps are most cost-effective when they’re properly sized and installed correctly. We can provide estimates based on your current energy usage and the specific equipment we’re recommending, but real savings become clear after your first full year of operation.
Heat pumps need regular filter changes every 1-3 months depending on usage and filter type. The outdoor unit should be kept clear of debris, snow, and vegetation that could block airflow. Annual professional maintenance includes checking refrigerant levels, cleaning coils, inspecting electrical connections, and verifying that all components operate correctly. This preventive maintenance helps catch small issues before they become expensive repairs and keeps your system running efficiently. Our Dempsey Comfort Club membership program includes scheduled maintenance visits so you don’t have to remember when service is due. Regular maintenance typically extends equipment life and maintains warranty coverage.
