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.

Professionally done and took care to cover all entry floors to the house for the installers to remove the old furnace and install a new furnace.
I also made recommendations of the tankless water heater that we had installed and items to address. We did not know they also installed tankless water heaters.
Price was not the cheapest nor the most expensive of my quotes. It's the quality of the installation that makes for a good AC system. The twins' knowledge & professionalism was evident in the small details:
Very clean work. Greg made sure that the refrigerant level & temperature were correct. They reinstall the insulation & vapor barrier around the wall. The outside electrical cords were secured to the wall. Proud to support this local company. Thank you.
Great team of guys came to do the work. Very professional. Arrived on time worked very efficiently and were very clean. They answered any questions we had without hesitation. The air conditioner works great and is so quiet. I highly recommend them and they don't try to up-sell anything right from the start.
The service was prompt, professional and very courteous. Competitive price. Would highly recommend this company.
Excellent workmanship, and quick response. Would recommend Twintech to anyone.
My existing 15-yr old A/C went down on me during the first major heatwave of the season. Researched my options, as well as a few different installers, and decided on Twintech.
They gave me confidence right from the beginning. Extremely knowledgeable. Their communication was excellent - always responded to questions quickly. Given we were in a heatwave, they were fully booked. However, within days they were able to fit me in due to a cancellation. Upon learning that the Amana unit I was getting installed was on backorder, TwinTech went to bat for me with the manufacturer and was able to get me the next model up within a day, for the same price - Amazing!
As far as the installation was concerned, I couldnt be more impressed. These guys were clearly very experienced and did a fantastic job. Very clean, polite, timely & informative. They even thoroughly sealed all the exposed gaps in my ductwork. Ive had plenty of heating and cooling work done in the past and have never used the same contractor twice because Ive never been very impressed. However, from now on, Ill always be contacting Twintech first!
They were very friendly and took care of everything. The install looks great (and works great), they were very knowledgeable. Installed our a/c efficiently despite the difficult install location both inside and outside and they made it work.
Phenomenal service, so glad I found these guys a few years back after being "hosed" badly by 3 other companies. I've recommended them to so many, and they all are so thankful.
This company is fantastic. Dave came out and gave me a very honest and reasonable quote, unlike a quote received from another company. I had a bunch of questions that were easily answered and when I had questions regarding heating/cooling a previously unheated room above the Garage, Dave arranged for Greg to come out for an assessment of this new space and gave me his recommendation along with his professional thoughts on all of my options.
These guys have been nothing but Professional, honest and helpful along the way. I can't recall the two other guys doing the install, but they were great as well. Good workmanship, everything was cleaned up and everything functions as promised. I could go on and on about my experience, but it's all positive so what more could you want?
Give them a call, see for yourself. If I had to buy another furnace/AC or heat pump, they'd be my first call.
I hired twin tech to convert my townhouse heating from electric to gas and install a furnace and a/c unit. I had talked with many other vendors, and received several quotes, but chose them, and very happy I did. Here are some of the reasons why:
1. They were realistic about the timeline for the work, when they could start and how long it would take. (They said upfront, it was their busy season and would need to get back to me in 3 weeks, which they did):
2. They had a quote with options for me. They were clear about the entertainment of what they would and would not do (theyd build duct work, id need another contractor to box in ductwork). This allowed me to plan as I was my own general contractor for my renovations).
3. They spoke to me in a language I understood, neither too technical nor too simple. They answered all my questions as I had them. Everyone is so lovely to work with, the sales team and the contractors who are worked in my home.
4. Its been 4 m since the work was complete. They still answer my emails and my furnace is working very well!
I unabashedly recommend! Price, customer care and quality workmanship were all amazing!

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!
