Unnecessary Strains You’re Putting on Your Heat Pump System

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.
All staff concerned were total professionals. Sales rep Dave was like having an old friend at your house. No up selling or pressure, just good honest facts and figures. The owners and assistant who installed our unit worked quietly, efficiently and left our home clean. We could not have been happier with the service and attention we were given. We are so happy a family member recommended Twintech. She said "don't call anyone else, just call them...they are amazing". And they were!!! Thank you guys for the great work!!! A. Johnson
We are completing a large project adding an addition on to our house and couldnt be more pleased with our decision to trust Twintech with our hvac work. They removed and replaced the furnace, installed a new A/C unit, swapped our tank water heater for a tankless unit, and completed ducting and new A/C lines through the addition. Without hesitation we would recommend Twintech to anyone.
Honest, very personable , men of their word ,workmanship xcellent ,showed up when promised ,They do not try to up sell ,rather give good advice instead . Price was very fair in my opinion .We have a family member with a medical condition and I think they made us a priority .Very happy with these guys . (Nice guys ) Stu Leffler Ajax.
Very professional, courteous, knowledgeable staff. Sales staff (David Gergley) excellent in knowledge and getting the job setup and installation was very prompt. Greg and Peter (technicians) knew their stuff and stuck around after completion to make sure it all worked properly and that I understood how it all was installed and how the unit worked. Would highly recommend them! Thanks for a great job-house is now cool and comfortable.
I had Twintech install a brand new air condition back in June of this year and I'm very happy with their service. I have a very busy schedule so I sent out an email to 7 or 8 HVAC companies just to get an idea of what it would cost. Dave at Twintech and only one other company were able to give me an approximate quote through email. Many of the companies I reached out to didn't even respond. I decided to meet with Dave and he was very friendly and professional. He gave me a good quote for a name brand/energy efficient AC with installation from their certified technicians. It was an easy decision to go with them.
Within a week I had the unit installed and working perfectly. Their technicians were very helpful and answered all of my questions. I'll definitely be calling them back for all of my HVAC needs in the future.
The people from Twintech were very friendly and personable...from the salesman to the installers. The installation was done as scheduled. I love my new air conditioner. My neighbour has a York and that thing is so noisy compared to my Goodman!! Thanks Twintech!!
Thank you, Twintech. They installed an A/C in my home in the middle of a heat wave which we appreciated very much. I found the team good, not overly friendly, other than the brothers. Dave, the salesperson was awesome, and, it's because of him that I was sold on using Twintech. I had other questions about additional work I am curious about and would have liked them to follow up and provide a quote. Other than that, which ultimately is not related to the great work they did, I would definitely recommend them, although I don't believe they go outside of Durham (check with them).
We have used this company a few times so I can't remember exactly what we paid but I do know that their fees are always very reasonable.
The first time we called Greg was when our furnace conked out while we were away. He came right away, showed me the problem and fixed it immediately.
The second time was when we needed an air conditioner moved and lifted to a platform. Again, he showed up on time, completed the job quickly (including a new gas line) and the fee was very reasonable.
We have received a quote from Greg to replace the air conditioner and furnace and when we are ready to move ahead, we will be calling him.
I have no hesitation in recommending TwinTech!
Our rating for Twintech is 5/5 stars. They are very professional and efficient, and the transparency they maintain right from the preliminary assessment till the day of the work is a testament to their experience in the field. We had Twintech replace our air conditioning and furnace, and we appreciate the efforts taken by Greg.
After 18 years my Air conditioner died in the middle of a heat wave. I entered my information on Home Stars and within the hour Dave from Twin Tech responded and offered to meet me as soon as possible depending on my availability. Dave was very knowledgeable about the products Twin Tech offered and even though this was the first quote I received . I felt very comfortable in giving Twin Tech my business. maybe it was the professional approach. Needless to say that the crew with Greg and Grant arrived promptly at the time they committed to were very professional and within a few hours had the place cool. They cleaned up and one would never know that I had work done . I know that the System is new and I probably wont need to worry about it for some time. However with the professionalism displayed by the crew I feel assured that should I need to call for service Twin Tech will respond. I also know that should I need a new Heating system I will go with Twin Tech. Keep up the good work.

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.
Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!
Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.
We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!
TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
