Heat Pumps: Frequently Asked Questions
In recent years, heat pumps have become one of the most popular choices for heating and cooling in homes and businesses. After all, their efficiency and versatility give them a leg up on traditional air conditioners and furnaces.
But despite their popularity, heat pumps remain a mystery to many homeowners looking to upgrade or replace their current heater or AC. This article will clear the air by answering some of the internet’s most common questions about heat pumps: how they work, why they’re worth installing, and how to tell when they need repairs.
What Is a Heat Pump (and How Does It Work)?
A heat pump is a type of HVAC system that uses virtually the same technology as an air conditioner – but unlike a normal AC, it can provide both cooling and heating capabilities in the same package.
A heat pump system involves an indoor air handler and an outdoor condenser unit. Copper pipes carry a chemical refrigerant between the two units. In cooling mode, the air handler blows indoor air over evaporator coils, transferring the heat of the air to the refrigerant inside the coils. The refrigerant is then pumped to the outdoor unit, where that heat energy is dispersed by blowing air over similar coils. In heating mode, this process is simply reversed, capturing heat energy from the outdoor air and transferring it indoors.
There are two main types of heat pump systems: ducted heat pumps and ductless heat pumps. Ducted, or central, heat pumps use one large air handler unit to distribute heated or cooled air throughout the home’s air ducts. Ductless heat pumps (also called mini-split heat pumps) instead use multiple smaller air handler units, usually mounted on the walls, to deliver air directly to all the rooms in the house.
What Are the Benefits of Heat Pump Systems?
Whether homeowners opt for a central heat pump or ductless mini-split heat pump, there are several benefits of installing this type of HVAC system:
- Lower Energy Bills – Heat pumps are significantly more energy-efficient than traditional ACs and heaters, so homeowners can enjoy impressive savings on their utility bills. This is especially true for ductless heat pumps, which offer even greater zone control and help prevent heating or cooling empty rooms.
- One System Handles Everything – Since heat pumps are effective at heating and cooling, homeowners won’t need to install separate air conditioners and heaters.
- Lower Maintenance Costs – Heat pumps tend to last longer and require less overall maintenance than traditional heating and cooling systems, and having everything in one system helps reduce service costs.
- More Eco-Friendly – Since they draw on existing heat energy in the air (or underground in the case of geothermal heat pumps) rather than generating heat directly from electricity or burning fuel, heat pumps are the most environmentally friendly type of HVAC system.
What Are Some Signs That a Heat Pump Needs Repairs?
Heat pumps can last 15 years or more with proper maintenance, but it’s important to be able to spot signs of trouble when they arise. This way, homeowners can address any issues before they worsen and cause bigger problems. Here are a few signs of a malfunctioning heat pump:
- Little or no air coming from the vents
- The home isn’t reaching the desired temperature
- The heat pump runs constantly without shutting off
- The heat pump only runs for a few minutes before shutting off (known as short cycling)
- The heat pump circuit breaker keeps tripping
- Strange smells or sounds coming from the air handler or outdoor unit
- The energy bill is higher than normal for no apparent reason
If homeowners notice any of these warning signs, they should call a professional for heat pump repair as soon as possible. Catching and fixing these problems early can help save money on repairs, extend the heat pump's life, and keep the home nice and comfy year-round!
