Maintaining a properly functioning HVAC system is critical to staying comfortable throughout Oregon’s diverse climate—frigid winters in Bend, hot summers in Redmond, and everything in between. Unfortunately, many homeowners unknowingly make HVAC mistakes that can lead to higher energy bills, reduced comfort, and expensive repairs.
Here are the top five HVAC mistakes Oregon homeowners often make, and how to avoid them, according to industry experts and energy-efficiency authorities.
1. Ignoring Regular HVAC Maintenance
Why It’s a Problem:
One of the most common mistakes is neglecting regular maintenance. A dirty filter, clogged condensate line, or worn blower motor can all reduce your system’s efficiency—and eventually cause a breakdown.
Routine tune-ups help your system last longer, work more efficiently, and save you money over time. According to Smarter House, well-maintained systems use up to 15% less energy than neglected ones.
What You Should Do:
Schedule HVAC maintenance at least twice a year—once before the cooling season and once before the heating season. This includes changing air filters, checking refrigerant levels, and inspecting components for wear or damage.

2. Using the Wrong Thermostat Settings
Why It’s a Problem:
Many homeowners believe that setting the thermostat lower in summer or higher in winter cools or heats the home faster. In reality, it simply causes the system to run longer—leading to wear and higher energy bills.
The U.S. Department of Energy recommends setting your thermostat to 78°F in summer and 68°F in winter when you’re home, and adjusting it while you’re away to conserve energy.
What You Should Do:
Install a programmable or smart thermostat to automatically adjust settings based on your schedule. This simple upgrade can reduce heating and cooling costs by up to 10% annually (Energy.gov).
3. Blocking Vents and Air Returns
Why It’s a Problem:
Placing furniture over vents, closing registers in unused rooms, or blocking return air ducts disrupts airflow. This puts added strain on your HVAC system and causes uneven heating or cooling throughout the home.
According to Bob Vila, blocked vents can increase your energy usage and even damage your system due to pressure imbalances.
What You Should Do:
Make sure all supply and return vents are clear and open. Even in unused rooms, airflow should be maintained to ensure system balance and efficiency.
4. DIY HVAC Repairs or Installations
Why It’s a Problem:
Attempting DIY repairs without proper knowledge or tools can void your warranty, compromise your system’s safety, and lead to expensive consequences. HVAC systems are complex and require precise calibration and professional handling—especially in Oregon’s variable climate.
What You Should Do:
Always rely on licensed professionals for repairs, installations, and even inspections. Einstein Pros offers trusted HVAC services across Central Oregon and employs experienced, licensed technicians.

5. Skipping HVAC System Sizing When Replacing Equipment
Why It’s a Problem:
Replacing your furnace or AC unit with a model that’s too large or too small for your home can lead to inefficiency, short cycling, and premature wear. Oversized systems cool or heat too quickly, which might sound good—but they never run long enough to remove humidity or evenly heat/cool your home.
What You Should Do:
Have a professional perform a Manual J Load Calculation, which takes into account square footage, insulation, window size, and more. This ensures your system is perfectly matched to your home.
Einstein Pros offers HVAC consultations to help Oregon homeowners select the right size and type of unit for their exact needs.
Bonus Tip: Don’t Forget About Air Quality
Oregon’s wildfire season can severely impact indoor air quality. Your HVAC system plays a key role in filtering particles and pollutants. Make sure you’re using the correct filters (MERV rating 8–13 is ideal for most homes) and replace them every 30–90 days—or more often during high smoke periods. Visit AirNow.gov to track local air quality.
Final Thoughts
Avoiding these HVAC mistakes isn’t just about saving money—it’s about improving your home’s comfort, safety, and efficiency. Whether you’re a new homeowner in Bend or a long-time resident of Redmond, keeping your HVAC system in peak condition should be a top priority.
