Unnecessary Strains You’re Putting on Your Heat Pump System
Posted On: March 19, 2026
Your heat pump is designed to run efficiently and consistently, even in Ontario’s unpredictable climate.
But certain habits and home conditions can put unnecessary strain on the system, forcing it to work harder than it should.
Over time, this leads to higher energy bills, reduced performance, and costly repairs.
Here are the most common ways homeowners unintentionally stress their heat pump systems.
1.
Constantly Adjusting the Thermostat
Treating your thermostat like a volume knob doesn’t help.
Heat pumps are built to maintain steady temperatures, not handle constant up-and-down changes.
What happens:
The system works harder to recover temperature swings
Efficiency drops
Components wear out faster
Big temperature jumps won’t heat your home faster, they’ll just make your system miserable.
2.
Blocking Airflow Inside Your Home
Furniture placement matters more than people think.
Blocking vents or returns restricts airflow, forcing your heat pump to work harder to circulate air.
Common mistakes:
Placing couches or beds over vents
Closing too many vents in unused rooms
Dirty or clogged air filters
Poor airflow is one of the fastest ways to reduce efficiency.
3.
Ignoring Regular Maintenance
Skipping maintenance is basically asking for problems later.
Dust buildup, worn parts, and minor issues can quietly strain your system over time.
Consequences include:
Reduced efficiency
Higher energy costs
Increased risk of breakdowns
Routine maintenance keeps your system running the way it’s supposed to.
4.
Letting the Outdoor Unit Get Buried or Blocked
Your outdoor unit isn’t decorative.
It needs space to breathe.
Snow, ice, leaves, and debris can block airflow and force the system to work harder.
Watch for:
Snow buildup around the unit in winter
Leaves and debris in warmer months
Objects placed too close to the unit
If your heat pump can’t move air properly, performance drops quickly.
5.
Poor Insulation and Air Leaks
Your heat pump can’t win against a house that leaks heat.
Drafty windows, poor insulation, and air gaps force your system to constantly replace lost heat.
This leads to:
Longer run times
Higher energy consumption
Uneven indoor temperatures
Your system ends up doing double the work for half the result.
6.
Running the System with Dirty Coils
Indoor and outdoor coils play a huge role in heat transfer.
When they’re covered in dirt or debris, efficiency drops and strain increases.
Symptoms include:
Reduced heating or cooling performance
Longer run cycles
Increased energy usage
Clean coils = less effort for the system.
7.
Oversizing or Undersizing the System
If your heat pump isn’t properly sized for your home, it’s always going to struggle.
Undersized systems:
Run constantly
Struggle to maintain temperature
Oversized systems:
Short cycle frequently
Wear out faster due to constant starts and stops
Proper sizing isn’t optional.
It’s critical.
8.
Ignoring Strange Noises or Performance Changes
Small issues don’t stay small.
If your system starts making unusual noises or behaving differently, ignoring it just gives the problem time to get worse.
Examples:
New or louder sounds
Inconsistent heating or cooling
Sudden drops in performance
Early fixes are always cheaper than late repairs.
9.
Using Emergency Heat Too Often
Emergency or auxiliary heat is there for extreme conditions, not everyday use.
Relying on it too often:
Increases energy costs significantly
Puts extra strain on your system
Reduces overall efficiency
If your system constantly switches to emergency heat, something’s wrong.
Final Thoughts
Most heat pump strain doesn’t come from extreme weather, it comes from everyday habits and overlooked issues.
The good news is that many of these problems are easy to fix once you know what to look for.
By improving airflow, maintaining your system, and addressing home efficiency issues, you can reduce strain, lower energy costs, and extend the life of your heat pump.
Your system will still work hard.
It just won’t feel like it’s being punished for existing.

Received a new range and needed someone to disconnect the old range and connect the new gas range. They did a thorough job and were kind enough to remove the old range from the house. Thank you!

Very satisfied with this company! Salesperson Dave was very good, very knowledgeable and gave me the impression that he wanted to sell me what I needed rather than what would put the most money in the company's pocket. He also called back after the installation to see if I was satisfied with the result. The installation crew of Greg, Grant and Peter did a great job. They arrived on time, completed the job quickly, answered all my questions and thoroughly cleaned up. They told me to call if I had any further questions. They left me with the impression that they really cared about their work and my satisfaction and that it wasn't " just a job". Prior to researching for a new furnace, I had never heard of this company but I'm glad that I did and would highly recommend them to anyone looking for a new furnace or air conditioning unit. They may be small but they do a great job!!

I first met Greg and Grant (The Twin Brothers from Twin Tech - yup -it's not just a cool company name) back in 2014 when our furnace broke down and they installed our Carrier Furnace and AC that we purchased through Sears. I liked them instantly when I met them due to their friendly and professional service, and the fact that they didn't mind taking a little extra time to explain things in terms I could understand. Since that time they have reached out to me at least once a year to ensure that everything was running smoothly with my system and to keep me appraised of their evolving services. Due to this high level of proactive customer service I didn't hesitate to call and obtain their help for a Gas Stove removal and installation. When I scheduled the call Greg and Grant let me know that they would arrive the morning of the appliance delivery to disconnect the old gas stove, and then return in the afternoon to connect the new stove. Sure enough, they did just that as promised. Where they exceeded my expectations is with the extra level of support helping to assemble the burners and grills on the stove and in the oven. This may seem like a small thing to some but to my wife who was at home during this entire process it meant a stress free transition to the meal prep for the day. When I called home to ask about the install she commented that, "they left the place cleaner than it was when they arrived and they setup all the grills on top of the stove and in the oven... they didn't have to do all that -Wow!". You know what they say, Happy Wife, Happy Life. So in summary, I am recommending Twintech Heating & Cooling for all of your Furnace, Air Conditioning, and Gas Line needs. I've even called on these guys to help swap out a leaky water valve. They are just so easy to reach and communicate with by phone, and they don't mind a text message to confirm the details. You can rest easy when you have the Twins on your side as an extension of your household maintenance plan.

First thing, they actually showed up for a quote. Other big name companies in the area didn't even return my call , job was done as expected and new equipment is quiet and installed very clean and professional. Would highly recommend these guys.

They removed our old furnace and replaced it with a new furnace and AC system.

Work was performed in a clean and timely manner. The furnace and metal work was performed by the Twintech team (did not require separate contractor to do the metal work). Energy audit was arranged and promised rebates were received. The overall price was very competitive. We have recommended Twintech to several of our friends and family. Awesome job.

Grant and Greg installed a heating and AC system in our new Linwood post and beam home. Post and beam can be challenging structures for running ductwork and their high ceilings and open concept frequently frustrate efforts at balancing air flow and controlling temperatures. But these guys did it and did it right the first time. Even the building inspector was impressed with what he saw. More importantly, the boys brought a high degree of trust and integrity to the job. Something in short supply these days.

Very polite and professional. They removed my o
ld furnace and A/C and installed my new ones. They were efficient and thoroughly cleaned up when they were done! I would highly recommend them!

Pro from start to finish. They were able to fix my gas fireplace at very little cost as well.
