With Portland’s damp winters and mild climate, it’s important to select the right HVAC system. In the Pacific Northwest (PNW), heat pumps and furnaces are both considered effective options for the climate. Some homeowners also opt for dual fuel systems, which offer powerful furnaces on the coldest days and energy-efficient heat pumps for the rest of the time.
Whether you need a heat pump repair or a furnace repair, Central Air Heating, Cooling & Plumbing can help. We can evaluate your existing setup to determine the best option based on your performance needs, efficiency goals, and PNW energy costs.
How Each System Works in the Pacific Northwest
To determine the right HVAC system for the Willamette Valley, it’s essential to understand how they work first. Because of Portland’s mild climate, heat pumps and furnaces can both be useful options.
Heat Pumps
Heat pumps function by transferring heat using refrigerants in a thermodynamic cycle. Even when it is quite cold outside, the refrigerant is able to absorb the existing heat and bring it indoors. Because they use heat transfer technology instead of combustion, heat pumps offer an incredibly energy-efficient heating solution.
During Portland’s long, damp winters, temperatures mostly stay above 35°F to 40°F. As a result, heat pumps are an incredibly effective option. Plus, they are able to reverse the transfer of heat in the summer, ensuring a cool, comfortable home during the hottest days of the year.
Furnaces
Unlike heat pumps, furnaces create heat through combustion (gas) or resistance (electric). Because of their powerful heating capacity, they are excellent HVAC units to have during Portland’s rare cold snaps. When temperatures dip below freezing, it helps to have a furnace installed to warm your home.
Head-to-Head Comparison for a Portland Home
What’s better: a heat pump or furnace? To get a better understanding of which system works best, let’s review a head-to-head breakdown of each system’s benefits and drawbacks.
- Energy Efficiency & Cost: When it comes to energy efficiency, heat pumps clearly come out ahead. You can use less energy to heat your home to the same temperature, leading to lower Pacific Power and Portland General Electric (PGE) bills. In comparison, furnaces are less efficient.
- Cold Weather Performance: Older heat pumps can struggle when temperatures get below freezing, although newer models handle cold temperatures well. However, furnaces really shine when it comes to cold performance. A furnace’s powerful heating ability provides peace of mind when temperatures start to drop.
- Installation and Repair Costs: In general, installing a heat pump will cost a bit more than installing a natural gas furnace. However, there are some rebates and incentives available that can defray the cost of an energy-efficient heat pump. While costs can vary for getting a heat pump repair or furnace repair, furnace repairs in Portland tend to be less expensive.
Alternatively, homeowners can get a dual fuel system and enjoy the best of both worlds. This type of system uses a heat pump most of the time, which maximizes its energy efficiency. Then, the furnace kicks on when it reaches a set temperature. For the Willamette Valley, this option provides the best of both worlds. You get energy-efficient heat when temperatures are above freezing and a formidable heating capacity during frigid temperatures.
Common Heating Repairs You Might Face
To determine the right HVAC for Portland’s climate, it also helps to compare the type of repairs you may need to perform.
The Most Frequent Heat Pump Repairs
At Central Air Heating, Cooling & Plumbing, we often encounter a few common heat pump repairs in Portland. Because of our damp air, evaporator coils are more likely to freeze. Additionally, refrigerant leaks and reversing valve failure are also fairly common.
- Frozen Coils: Dirty coils, clogged filters, and low refrigerant can cause the evaporator coils to transfer heat less effectively, increasing the likelihood that they will ice over. These underlying problems must be addressed to stop coils from freezing.
- Leaky Refrigerant: When refrigerant leaks out, it causes your heat pump to work harder to reach the same temperature and leads to added wear. Our HVAC technicians can quickly repair the leaks and recharge your refrigerant.
- Reversing Valve Failure: If the reversing valve fails, the heat pump can get stuck in a single mode, and your performance may decline. To prevent additional damage, this problem must be repaired by a professional.
The Most Frequent Furnace Repairs
When it comes to furnace repairs in Portland, we often see faulty ignitors, blower motor problems, and thermocouple issues.
- Faulty Ignitors: If the furnace fails to start or makes a clicking noise without starting, you may have a faulty ignitor. Dealing with gas and electric problems can be dangerous, so this repair should be left to the professionals.
- Thermocouple Issues: When your pilot light doesn’t stay lit or the furnace switches off inexplicably, a thermocouple issue may be at fault. Our team can troubleshoot by cleaning the thermocouple. If that doesn’t work, we can replace it.
- Blower Motor Problems: Strange noises, a lack of airflow, and an overheated furnace are all symptoms of blower motor malfunctions. Our HVAC technicians will troubleshoot this issue by replacing the air filter, cleaning the blower motor, inspecting the capacitor, and replacing any damaged components.
What’s the Best Heating System for You
In the Willamette Valley, there isn’t a single HVAC system that is the clear winner. It all depends on exactly what your underlying goals are.
- Eco-Conscious Homeowners: If your biggest concern is the environment, a high-efficiency heat pump uses less energy and is the best choice.
- Low-Cost Installations or Older Homes: For older homes that need a powerful source of heat to stay warm, a furnace is often the best choice. Because a reliable, high-efficiency furnace often costs less upfront, it’s a good choice if your family has a limited installation budget.
- Ultimate Peace of Mind: For high energy efficiency, lower power bills, and a warm home in any weather, a dual fuel system is the best option.
