You may have recently decided that you'd like to enjoy the tremendous versatility and efficiency benefits that heat pumps offer. However, switching over to a heat pump from a more traditional HVAC system isn't necessarily a simple matter. Here are a few things that you must think about before you decide to upgrade to a heat pump.

Air-Source or Geothermal?

Broadly speaking, there are two types of heat pumps: air-source heat pumps and geothermal heat pumps. Before deciding on anything else, you must figure out which of these two types would be a better fit for your home. All heat pumps use refrigerant to transfer heat between indoor and outdoor environments, though geothermal systems use a ground loop with a water-based solution to exchange heat with the earth. In both types, heat is absorbed through a heat exchanger, causing the refrigerant to evaporate. It then moves into a compressor, which increases its pressure and temperature. Once heated, the refrigerant travels to a second coil, condensing and releasing heat into the desired space. When the system is in cooling mode, the refrigerant absorbs heat from the air inside your home and releases it outdoors. When it's in heating mode, the refrigerant does the opposite. The primary difference between air-source and geothermal heat pumps concerns the source from which each draws and releases heat. Air-source heat pumps operate using the air above ground, while geothermal systems rely on the steady underground temperatures and use a buried loop system to transfer energy. In Toms River and much of New Jersey, the ground below the frost line maintains a steady temperature of around 55 degrees Fahrenheit year-round. This stable underground temperature makes geothermal systems highly efficient, especially during the peak heating and cooling seasons, because they don’t have to work against extreme outdoor air temperatures. However, geothermal systems are more expensive and complex to install. They require either a large horizontal area for trenching or vertical drilling for the ground loop, which may not be feasible on smaller properties common in some areas of Ocean County. One final consideration is each system’s expected lifespan. The indoor unit of a geothermal heat pump typically lasts 20–25 years, and the underground loop can last over 50 years. In contrast, an air-source heat pump usually lasts around 12–15 years with proper care. One Hour Heating & Air Conditioning® can provide both air-source and geothermal heat pumps for homeowners in Toms River, NJ.

Efficiency

Another essential thing to consider is efficiency. We've already mentioned how efficient the various types of heat pumps are and how they compare to other HVAC systems. However, there is more to consider. Before buying any heat pump, you should look at its SEER2 (Seasonal Energy Efficiency Ratio 2) rating for cooling and HSPF2 (Heating Seasonal Performance Factor 2) for heating. The higher these ratings, the more efficient your system will be, which can translate into lower utility bills. We also recommend looking for models that carry the ENERGY STAR® certification. Even with a high-efficiency system, it's important to understand that performance naturally declines over time due to wear and tear. Components age and minor issues can reduce overall efficiency if not addressed. That’s why regular professional maintenance is essential, typically scheduled annually or semi-annually. While every system is different, many homeowners will encounter their first repair within five to ten years. Our team of trained technicians is ready to handle both routine maintenance and unexpected repairs to keep your system running at its best.

Home Size and Layout

To get the most out of your heat pump, you must ensure that it’s properly matched to your home’s size and layout. That means selecting a system that’s neither too large nor too small. An oversized unit may cool your home too quickly, causing it to shut off before completing full cycles. This can lead to uneven temperatures and long-term strain on the equipment. On the other hand, a unit that’s too small may run constantly, driving up energy use and increasing the risk of a breakdown. To prevent this, your contractor should perform a Manual J load calculation, a professional assessment of your home’s size, insulation, windows, and other key factors, to determine the right-sized unit for your needs.

Ductwork and Insulation

If your home already has ductwork, your heat pump will likely use it to distribute conditioned air. However, ductwork issues can seriously reduce your system’s efficiency. Leaks from poor sealing or degraded materials allow conditioned air to escape, forcing your system to work harder. Buildup of dust or debris can restrict airflow and reduce performance. That’s why it’s important to have your ductwork professionally inspected and cleaned before installing a new system. Similarly, your insulation plays a critical role in keeping outdoor air out and indoor air in. Proper insulation helps maintain stable indoor temperatures, reducing how hard your system has to work. Weak or spotty insulation can result in energy loss and put unnecessary strain on your new heat pump.

Selecting the Right Contractor

Once you've chosen the right heat pump, it’s just as important to select a qualified contractor for the installation. Replacing your old system and installing a new one is a complex job, and poor workmanship can lead to future problems. It can be hard to know who to trust, especially without industry knowledge. When evaluating contractors, we recommend asking about:

  • HVAC licenses and certifications
  • General liability and accident insurance
  • Experience with air-source or geothermal heat pumps
  • Customer testimonials and references
  • Installation timelines
  • Details of the manufacturer’s warranty

Be sure to pay close attention to the warranty coverage. Some warranties only include parts, while others also cover labor. Although more comprehensive warranties may come with a higher upfront cost, they offer better long-term protection and value. Purchasing a heat pump is an important decision, and we can guide you through every step. Once your new system is installed, our experts provide ongoing repair and maintenance services to help extend its life and keep it running smoothly.
