Heat pumps are one of the most energy-efficient ways to heat and cool your home, but improper installation can lead to higher energy bills, poor performance, and lost rebates.
To get the best results, it’s important to avoid common installation mistakes and work with a Mass Save HPIN-certified contractor to ensure everything is done correctly.

Mistake #1: Choosing a Non-HPIN-Certified Contractor
The Problem:
Only Mass Save HPIN-certified contractors can process rebate applications. If you hire a non-certified contractor, you won’t qualify for up to $10,000 in rebates—and you may end up with a subpar installation.
How to Avoid It:
- Always verify that your contractor is HPIN-certified through the Mass Save contractor directory.
- Work with an experienced HPIN-certified contractor like Lund Plumbing & Heating to ensure eligibility.

Mistake #2: Installing the Wrong Size Heat Pump
The Problem:
If a heat pump is too small, it will struggle to heat or cool your home, leading to high energy costs. If it’s too large, it will short-cycle, causing uneven temperatures and unnecessary wear on components.
How to Avoid It:
- Work with a qualified installer who performs a Manual J load calculation to determine the correct size for your home.
- Avoid contractors who guess the size based on square footage alone.

Mistake #3: Poor Placement of Indoor & Outdoor Units
The Problem:
Incorrect placement of the indoor or outdoor unit can reduce efficiency and increase wear and tear.
Common errors include:
- Installing the outdoor unit too close to walls or fences, restricting airflow.
- Placing the indoor unit too high or too low, affecting air distribution.
- Exposing the outdoor unit to excessive snow, debris, or direct sunlight, impacting performance.
How to Avoid It:
- Install the outdoor unit in a well-ventilated, shaded area to prevent overheating.
- Ensure the indoor unit is mounted at the correct height for even air circulation.
- Keep the outdoor unit elevated to avoid snow buildup in winter.

Mistake #4: Skipping Insulation & Weatherization Upgrades
The Problem:
A heat pump works best in a well-insulated home. Without proper insulation and air sealing, warm or cool air escapes quickly, reducing efficiency and comfort.
How to Avoid It:
- Complete a Mass Save Home Energy Assessment before installation.
- Follow Mass Save recommendations for insulation and air sealing upgrades before installing a heat pump.
- If required, complete weatherization improvements before applying for rebates.

Mistake #5: Incorrect Refrigerant Charge & Airflow Settings
The Problem:
Heat pumps rely on a precise refrigerant charge and proper airflow to function efficiently. If either is off, you may experience:
- Higher energy bills
- Poor heating and cooling performance
- Increased wear and tear on the system
How to Avoid It:
- Ensure your contractor checks and adjusts the refrigerant charge according to manufacturer specifications.
- Confirm that airflow is balanced properly throughout the home.
- Ask your installer to test the system’s performance after installation.
