What Size Heat Pump Do I need?

So, your trusty AC or furnace has finally thrown in the towel. You start researching replacement options and keep running into this thing called a heat pump.

It sounds high-tech, maybe even futuristic — but what is it, and more importantly, how do you know what size heat pump you actually need? Choosing the right size is not just about comfort — it also impacts your energy bills, the lifespan of your system, and even the air quality inside your home.

What Is a Heat Pump?

A heat pump is a versatile home comfort system that can heat and cool your space. Unlike traditional furnaces, which generate heat by burning fuel or electric resistance, a heat pump moves heat from one place to another — pulling warmth from the air, ground, or water outside your home and transferring it indoors during winter.

In the summer, the process reverses, and the system works like an air conditioner, removing heat from your home to keep it cool.

Because it moves heat rather than creating it, a heat pump can operate much more efficiently than conventional heating systems, helping homeowners save on energy bills while staying comfortable year-round.

Signs of a Properly-Sized Heat Pump

When properly sized, a heat pump will:

  • Maintain a consistent temperature throughout your home.
  • Operate efficiently without wasting energy.
  • Reduce wear and tear on components.
  • Improve indoor air quality with balanced humidity control.
  • Lower your monthly utility bills.

Signs of an Improperly-Sized Heat Pump

If your heat pump is the wrong size, you may notice:

  • Hot and cold spots around your home.
  • Higher-than-expected energy costs.
  • Frequent repairs or early breakdowns.
  • Excess humidity in the summer.
  • Constantly running or short cycling equipment.

Getting the size right from the start prevents these issues and ensures long-term comfort.

How Heat Pump Size Is Measured

Heat pumps are sized based on tonnage or BTUs (British Thermal Units).

  • Tonnage: Residential heat pumps typically range from 1.5 tons to 5 tons. One ton equals 12,000 BTUs of heating or cooling capacity.
  • BTUs: This is the actual measurement of heating or cooling power. For example, a 3-ton heat pump provides about 36,000 BTUs.

Typical Heat Pump Sizing by Home Size

  • Smaller Homes (around 1,000 sq. ft.): A system close to 2 tons, or about 24,000 BTUs.
  • Mid-Sized Homes (about 1,500–2,000 sq. ft.): A system between a 3-ton (36,000 BTU) and 4-ton (48,000 BTU) unit.
  • Larger Homes (2,500 sq. ft. and above): Bigger spaces typically call for a 4- to 5-ton system, delivering 48,000 to 60,000 BTUs.

Every home is unique, which means there is no universal sizing. Trusted HVAC professionals will perform a calculation to determine the exact size you need. Because so many factors are involved, professional calculations are always more reliable than online calculators or square-foot estimates alone.

Steps to Take Before Choosing a Heat Pump

If you’re considering a new heat pump, here’s what to do:

  1. Schedule a Home Energy Audit: This identifies insulation gaps, air leaks, and other issues that may affect your heating and cooling needs.
  2. Have a Load Calculation Performed: Your HVAC contractor from Murphy’s Plumbing will use Manual J standards rather than square-foot estimates.
  3. Consider Efficiency Ratings: To maximize performance, look for high SEER2 (cooling) and HSPF2 (heating) ratings.
  4. Think About Zoning: If you have a large home, zoning or multiple smaller units may be better than one oversized system.
  5. Discuss Options With a Professional: Every home is different, and your Murphy’s Plumbing pro can recommend the right size and model for your situation.

Murphy’s Plumbing for a Heat Pump Installation

When it comes to choosing the right heat pump size, there’s no one-size-fits-all answer. Your home’s square footage, insulation, climate, and many other factors all play a role. While it’s tempting to estimate, the safest — and most cost-effective — approach is to have a professional from Murphy’s Plumbing perform a detailed load calculation.

With the right heat pump size, installed correctly by an experienced HVAC contractor, you’ll enjoy consistent comfort and reliable performance for years to come. A heat pump can produce two to four times more heating output than the electricity it uses, so energy savings can also be achieved if you upgrade from a furnace or other form of heating.

How to Know If Your Home Needs Duct Cleaning Services

By Ashley Dennon, Oliver Heating and Cooling

It’s no secret that having an efficient heating and cooling system is essential. You and your family need relief from hot summer days and chilly winter nights. However, one thing many homeowners don’t often think about is everything that goes into an efficiently functioning heating, ventilation, and air conditioning (HVAC) system, particularly the need for air duct cleaning. That’s where Oliver Heating and Cooling comes in!

What is air duct cleaning?

The process of cleaning your air ducts helps remove buildup, including dirt, allergens, dust, debris, mold spores, bacteria and viruses. In some homes, additional filtration systems may be necessary to reach optimal indoor air quality, including adding a humidifier or dehumidifier or optimizing filters or air scrubbers.

There are a few key signs that the ducts in your home need to be cleaned:

  • Your utility bills have suddenly spiked without an apparent reason.
  • You’re experiencing a problem with insects or rodents in your home.
  • You have a buildup of dust around the vents in your home.
  • You or a family member has suddenly had an onset of respiratory or allergy symptoms.

Benefits of duct cleaning services

There are many benefits to cleaning the air ducts in your home. The most important benefit, of course, is improving the air quality for your family. Clean air improves your health and helps to keep respiratory and allergy problems at bay. In addition, removing the buildup inside of your ducts will allow for your HVAC system to be more efficient which will in turn lower your heating and cooling costs.

How often should you clean your air ducts?

At Oliver Heating and Cooling, we recommend duct cleaning every 3-5 years. Keep in mind, there are a few outlying factors that may affect your schedule. For example, you should always have air ducts cleaned after new construction or a major renovation in your home due to excess dust and debris. Also, if you have had any water damage or signs of mold in your home, air duct cleaning is essential to avoid triggering respiratory problems.

Could your home benefit from air duct cleaning? An HVAC services company like Oliver can help. You can request information online or give us a call. We’ll make sure the air quality in your home is safe for your family.

Our Home Should Feel Safe and Comfortable All Year

Heat-induced illness is a very real threat as temperatures climb during the summer. Heatwaves and other hazardous weather can settle in, and, if you aren’t taking the proper precautions, things can take a turn for the worse. While heat and humidity make us all uncomfortable, there are ways to mitigate risk and ease the impact of extreme temperatures. Oliver is here to provide some helpful tips. If you live in the Delaware Valley, we can give your home an air conditioning safety inspection so that you know you’re ready to handle the heat.

The best way to safeguard yourself from heat-induced illness is to stay hydrated. It is recommended to drink eight glasses of water a day–not just to keep your body hydrated, but also to help flush out toxins. While sports drinks or caffeinated beverages may help increase your body’s water level, they are not as effective because they can sometimes contain other dehydrating elements. Staying hydrated will help reduce the risk of heat exhaustion and heat stroke.

Another important way to avoid the summer heat is to stay indoors in your climate-controlled home. Your air conditioner regulates the temperature inside your house and can be a haven for anyone at risk for heat-related illness. Making sure your air conditioner is in working order before the heat comes can help you avoid an emergency. The experts at Oliver recommend an annual home A/C safety inspection to make sure your system is clean, operational and running efficiently this season. By ensuring your home will be cool all summer long, you have one less thing to worry about.
