Unnecessary Strains You’re Putting on Your Heat Pump System

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.

by peter in Whitby on Twintech Heating and Cooling

Very impressed with this company. They show up on time , kept my place clean and after they left it looks like they were never there. Very professional team. Those people know what they doing . Their installation was on the highest standard. They are very knowledgeable especially they're worker Peter. I strongly recommend this company to everybody. After the installation I receive the call making sure I'm satisfied with their products and their job. Bravo!!!

by James in Bowmanville on Twintech Heating and Cooling

Greg and his brother were referred to us by a friend. They arrived when they said they would, did an exceptional job and left the place as tidy or tidier then they found it. Their professionalism is only surpassed by their kind and friendly demeanor. Even after several calls to help me with my high tech thermostat I feel that I could always call with any concern (No one responds to my texts as quickly as Greg) and have a friendly helpful response. I found out their grandfather started the company and now as a 3rd generation company, they are doing their grandfather proud. I would highly recommend Twintech over any other hvac company out there.

by RJW in Ajax on Twintech Heating and Cooling

Thanks to the guys at Twintech Heating for a great job installing a new hot water tank. They set a time and day to remove the old tank and install the new one. They were on time and had the work done quickly and cleaned up after they were finished. Excellent work and great value.

by Marilyn in Milton on Twintech Heating and Cooling

In November, we contacted Twintech for a quote on a high efficiency furnace plus installation. Dave, the sales representative for the company was very friendly and informative. Upon arrival at our home, he willingly showed us his company licenses, clearly explained the operation of a high efficiency furnace and answered all our questions to our satisfaction. As well, Dave was the only sales representative that we contacted that was willing to make the arrangements for an energy audit. For us, this was a big plus as we found the government rebate program somewhat confusing to navigate. The furnace was installed on the date that was arranged in an efficient and professional manner by Greg (the owner) and Peter. Both men worked diligently, throughout a long day to complete the job and upon finishing, left the job site immaculate. When a neighbour raised concerns about the furnace venting location, Greg located an alternative location and resolved the situation with diplomacy. We chose the Napoleon furnace for its excellent warrant;y on the heat exchanger and because it was made in Canada! In addition, to the furnace warranty, Twintech offered us a 5 year warranty on labour which speaks to the quality and pride this team has in their workmanship. It has been over a month now (with some of the coldest January days on record) since we have had the furnace installed. The furnace runs quietly and distributes heat more evenly throughout our 90 year old Toronto home. We can't speak highly enough of the Twintech team and are very satisfied with their workmanship and job ethics. We have no hesitation about recommending them.

by Barry in Toronto on Twintech Heating and Cooling

What more could you ask for! Grant and Greg Dainty provided a professional,diligent and thorough approach to the installation of my furnace. I would highly recommend there services.

by Hector in Scarborough on Twintech Heating and Cooling

Last week our Furnace failed overnight. We called Twintech to help us get it running again. They did a really thorough check on it, and got it running in less than an hour. Given that it was an old Furnace (+20 years old), we were giving two options: repair it or replace it. Instead of doing a repair on it that could break in a week or two, they recommended us to change it. I like that they were honest on the recommendation, not forcing a new furnace on us. At the end we went with a new Furnace. Twintech solutions service & salesman gave us recommendation on the size of the unit and many options that could work for our home. They ended up doing an excellent work in our furnace, replacing the filter to a better option and replacing some pieces that had water damage. They cleaned after themselves and leave everything even better than what they found. They even went far and beyond tiding up the hose connections that we had on the basement.

by Ryan Doherty in Whitby on Twintech Heating and Cooling

I am in the process of finishing my basement and wanted to make sure I got the low hanging duct work fixed in advance. After reviewing 5 quotes I selected Twintech to award the contract to. The price was competitive however what won me over was Grant's (co-owner) attention to detail and his ability to focus on what my goals and priorities were for the project. His team completed the job over 3 days as there was significant duct work changes and the relocation of all of the equipment. They also completed the job with little downtime so we weren't left overnight without heat during freezing winter temperatures.

by Private User from Oshawa on Twintech Heating and Cooling

My father woke up to no heat one Saturday morning. We had a few names that friends had recommended but while checking out the companies' ratings on HomeStars, we found Twintech with great ratings too. The other companies either didn't get back to us or didn't have time to come at such short notice. TwinTech made the time in their schedule for what they judged to be an emergency: no heat in the home of an elderly person. At no extra fee for a short notice, weekend visit. They recommended an upgraded furnace unit and explained that we would qualify for a rebate that would bring the price down to that of a lower model. They set us up with the rep from the MNR that covers the rebate so that we didn't have to deal with the paperwork & phone calls ourselves. Installation was quick, efficient, & smooth. We were so pleased with their service we ordered a new water heater too. Both are working great (efficient & quiet!) & my father is safe & comfortable. We can't say enough about how pleased we are with their service. We have already recommended them to others.

by joe calabro in Pickering on Twintech Heating and Cooling

Twintech Heating & Cooling. I just want to say thanks for helping me . My Furnace stopped working. And l phone Dave Getgley he set me up with Greg. What an amazing team they did a great job in setting me up with a new Furnace. Anyone that needed a new Furnace these are the guys to call. Thanks again for a job well done.

by Peter from Ajax on Twintech Heating and Cooling

Our home has had poor heating and air conditioning the past couple of years. Dave recommended a Goodman solution with more power than we had. Grant and Greg installed the units in late November. Heating is better than ever. We have a warm home again and look forward to the winter. Can't wait to see how the AC runs in 2018. Job was super clean and professionally done. Highly recommended.

by Aaron on Twintech Heating and Cooling

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.

by Linda on Twintech Heating and Cooling

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!

by Robert Rogers on Twintech Heating and Cooling

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.

by Robert Mizuno on Twintech Heating and Cooling

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!

by Ruth on Twintech Heating and Cooling

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!
