How to Improve Heat Pump Efficiency Before Summer

As spring rolls into warmer weather across Ontario, your heat pump is about to switch from heating hero to cooling workhorse.
If it’s still carrying the wear and tear of winter, it’s going to work harder, cost more to run, and deliver less comfort.
The good news? A few smart adjustments now can noticeably improve your system’s efficiency before summer hits.
Here’s exactly what homeowners should do.
Why Spring Prep Matters for Heat Pump Efficiency
After months of cold weather, your heat pump has likely dealt with: Ice buildup and repeated defrost cycles Dirt, salt, and debris accumulation Extended runtime during extreme temperatures
All of that can reduce airflow, strain components, and lower efficiency right when you need cooling performance the most.
Think of spring as your reset button.
1.
Clean the Outdoor Unit (This One Actually Matters)
Your outdoor unit took a beating over the winter.
Leaves, dirt, road salt, and debris can block airflow and force your system to work overtime.
What to do: Turn off power to the unit Gently rinse coils with a hose (not a pressure washer) Clear at least 2 feet of space around the unit Remove any debris stuck in the fins
Why it helps: Better airflow = less energy used to move heat.
2.
Replace or Clean Your Air Filter
A clogged air filter is one of the most common (and preventable) efficiency killers.
What to do: Check your filter monthly Replace or clean it if it looks dirty Use the correct size and rating (don’t guess)
Why it helps: Proper airflow reduces strain on the system and improves overall performance.
3.
Check Your Thermostat Settings
Spring is the perfect time to optimize how your system runs.
What to do: Switch from heating mode to cooling mode at the right time Avoid drastic temperature swings Consider upgrading to a smart thermostat
Why it helps: Consistent settings prevent unnecessary cycling and energy waste.
4.
Inspect and Clean Vents & Registers
Blocked or dusty vents can disrupt airflow throughout your home.
What to do: Vacuum vents and registers Make sure nothing is blocking airflow (furniture, rugs, etc.
) Open all vents unless professionally advised otherwise
Why it helps: Balanced airflow keeps your system running efficiently and evenly.
5.
Look for Warning Signs Early
Small issues in spring can turn into expensive breakdowns in summer.
Watch for: Weak airflow Strange noises Unusual smells Higher-than-normal energy bills
If something feels off, it probably is.
6.
Schedule a Professional Heat Pump Tune-Up
This is where the real efficiency gains happen.
A professional HVAC technician can: Clean internal components Check refrigerant levels Inspect electrical connections Calibrate system performance
Why it helps: Preventative maintenance keeps your system running at peak efficiency and extends its lifespan.
7.
Seal Air Leaks in Your Home
Your heat pump can’t be efficient if your home is leaking cool air.
What to check: Windows and doors Attic insulation Drafty areas around vents
Why it helps: Less air loss = less work for your system.
8.
Upgrade If Your System Is Struggling
If your heat pump is older or constantly underperforming, spring is the ideal time to consider an upgrade.
Modern systems: Use less energy Provide better cooling performance Operate more quietly
And you’ll beat the summer installation rush.

Greg and team were amazing! All interaction via email and text 100% professional. From consult to product recommendation their service was phenomenal!
Installed a Napoleon furnace (ecm dc drive variable 2-stage) and it was a game changer for the whole house. Blended air temperature through and through the entire house and its saving us money by cutting down our utility bill by ALOT!
We purchased a new cooling & heating system from Twintech and the team was fantastic. From sales to installation, the team were great to work with. Friendly (our dog even enjoyed having them over), professional and accommodating. Id recommend Twintech in a heart beat to anyone. Superb customer service.
End to end service. From quote, overseeing installation, contacting and making arrangements for energy audit. Warranty program is comprehensive. Cleaned up mess of assistant walking through my place without proper indoor foot covering when I pointed out that I was not happy about footprints on my floors.
In April we hired Twintech Heating & Cooling to replace our 20 year old water tank & 35 year old air conditioner. We got 5 estimates for the job & decided to go with Twintech for the following reasons.
- The Sales Manager, Dave, was very personable & knowledgeable as all of our questions were answered. (We had a list of questions we asked each of the contractors when we got the estimates)
- We got 5 estimates for the job. All contractors verbally told us they had the required qualifications but Dave was the only one to physically show us their license & insurance documentation.
- Twintech carried the Napoleon air conditioner & we wanted to support Canadian industry as it is assembled in Barrie On.
Safety is important at Twintech as demonstrated when we discussed with Dave, the need to change our install date because of freezing rain. Access was required by navigating a set of outside steps & Dave identified that safety took precedence.
On the installation date, Greg, Peter & Grant showed up on time & methodically accomplished the removal & installation of both units. The guys did a great job cleaning up as well.
When the job was completed we mentioned to Greg that we were pleased with the work they had done & were going to have them come out & do our furnace inspection in Sept. Greg said we can save our money as he had inspected the heat exchanger on the furnace while doing the job & there was no need to have another inspection in Sept. We were very impressed with Gregs initiative. This is top shelf service. Thank you Greg.
As the weather was too cool to complete a functional test of the air conditioner on the installation date, Dave made a follow-up call to us to see how things were going & Greg also came out to check the operation. No problems.
We are very happy we hired professionals like Dave, Greg, Grant & Peter & have no hesitation in recommending Twintech Heating & Cooling. They will now be our "go to" guys.
These guys are the best. From start to finish they exceeded my expectations and delivered a great product. They accommodated the nuances of my 100 year old home which was really appreciated. The install was easy to schedule and done fantastically. Im so excited to have an efficiently heated and cooled home.
Twintech were fast and efficient contractors. It only took 48 hours between an initial home visit and complete installation. The workmen were polite and hardworking. The site was left clean with the old furnace etc. removed. They helped arrange an environmental assessment in order that I could receive the maximum rebate. They even called me within a week to determine if I was satisfied with their work and to reassure me that I could call them anytime I experienced heating difficulties or had any questions. I recommend Twintech for your heating problems.
Courteous and professional service from initial consultation through to the installation. We highly recommend Twintech for outstanding service in the industry. Competitive pricing, professional and accurate advice, attention to detail, respect for their client's home and cleaning up at the completion of installation.
Last night was the coldest day of the year so far and I woke up to my house being 54 degrees... I called Twintech at 2:45am and Greg was on site by 3:30am. The furnace required a part and he returned to his shop and came back to my home around 4:15am, furnace up and running by 4:30am. THANK YOU TWINTECH! Your service is second to none.
After much research & getting 4 quotes, we hired Twintech team for our new furnace installation, prices were fair, they carried great product brands & more importantly installation was expertly done by one of the owners (Greg & his assistant Peter) which gave me an added piece of mind. Dave was very organized & answered all my questions in great detail, especially re: the Enbridge & Govt. rebate program.
My old air conditioner was 20 years old and developed a Freon leak and it was more cost effective to replace rather than repair. There are a large number of heating and air conditioning companies available in my area so I contacted several for quotes. Twintech heating and cooling responded quickly to the inquiry I left on their website and their sales person Dave came by the following day. He was knowledgeable about the field and was able to show copies of the various refrigeration and gas fitting licenses along with workmens compensation, TSSA and other certifications. He also suggested a particular manufacturer and model of AC unit appropriate to my house and gave me a quote. Since the price was reasonable, service had been good and the reviews on the internet were also good, I decided to purchase an AC unit from them. Installation was quickly scheduled. They showed up on time, did a good job installing the new unit including some sheet metal work to get the new heat exchanger to fit in the furnace duct, and cleaned up afterward. In addition, they noticed that my existing AC was installed too close to the furnace exhaust (based on building code) and were able to mount the new AC the appropriate distance from the exhaust. Overall, they did an excellent job and were a pleasure to work with.

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!
