What to Expect When Switching to a Heat Pump Unit

Switching to a heat pump is one of the smartest upgrades Ontario homeowners can make—but it’s also a big change. If you’re used to a traditional furnace and air conditioner setup, a heat pump works a little differently.
So what should you actually expect?
In this guide, we’ll walk you through everything—from installation to day-to-day use—so you can feel confident about making the switch.
The first thing to understand is that a heat pump doesn’t generate heat like a furnace—it moves heat.
That means:
Because of this, the way your home feels may be slightly different.
One of the biggest changes homeowners notice is how heat is delivered.
With a furnace:
With a heat pump:
This results in:
At first, some people think it’s “not heating enough”—but it’s actually working exactly as intended.
Heat pumps are designed to run for longer periods at lower intensity.
So don’t be surprised if:
This is normal—and actually more efficient.
Your energy costs may shift when you switch to a heat pump.
What to expect:
Your exact savings will depend on:
Modern heat pumps are designed to handle cold climates—but Ontario winters can still be demanding.
Depending on your system, you may have:
This ensures your home stays comfortable even during the coldest days.
Every home is different, so the installation process can look different depending on your setup.
You might experience:
Most installations are completed relatively quickly, but proper sizing and setup are critical for performance.
Heat pumps are efficient, but they still require regular care.
Routine maintenance includes:
The good news? Maintenance is typically straightforward and helps keep your system running efficiently for years.
Many homeowners notice a difference in how their home feels—not just in temperature, but in air quality.
Benefits can include:
This creates a more comfortable living environment year-round.
Heat pumps are generally quieter than traditional HVAC systems.
You may notice:
This is especially noticeable if your old system was aging or loud.
Switching to a heat pump can take a little getting used to.
Common adjustments include:
Once you adjust, most homeowners find the comfort level is actually better.
After the initial transition, the advantages of a heat pump really start to stand out:
It’s not just a new system—it’s a different, more efficient way to manage your home’s comfort.
Switching to a heat pump unit is a big step—but it’s one that comes with long-term benefits for comfort, efficiency, and sustainability.
Knowing what to expect helps you avoid surprises and get the most out of your system from day one.
At Twintech Heating & Cooling, we guide Ontario homeowners through every step of the transition to a heat pump—from system selection to professional installation.
If you’re considering making the switch, we’re here to help ensure it’s done right and built to last.
Great service and great people to deal with, from sales to installer. I highly recommend this company.
Twintech replaced our aging furnace and air conditioner recently. I highly recommend this company. Their quote was competitive, they were on time and respectful of our home and extremely professional. From the salesman to the installers and the owner who followed up afterward to ensure we were satisfied, we are very pleased with the service. We are looking forward to working with this company for all of our HVAC needs for the years to come. Excellent workmanship and service!
We wanted to get our AC replaced as it was 22-years old and added to this our furnace was costing more and more to repair. So, we decided to get both the furnace and AC replaced.
After going through a few quotes and product reviews we decided to go with Twintech. The three-men crew arrived early in the morning, wasted no time and got to work right away. By 2:00 pm, they were all done. Ive found their work to be top notch and they were completely professional. I had all my questions answered to my satisfaction both during the progress of their work and at end.
I have pleasure in recommending Twintech to anyone who is looking to get their furnace or Ac replaced

Our air conditioner died On a Saturday and within hours Dave came out to take a look and discuss replacement/repair options.
The new air conditioner was installed on the Wednesday. The new unit was installed quickly. The installers were friendly and cleaned up afterwards.
We noticed a slight leak around the furnace that night and they came out the next day and fixed the issue. It has been working great and is quieter than our previous unit.
Very satisfied and would highly recommend TwinTech.
I contacted TwinTech to replace my 20-year old A/C. Dave, their service rep, promptly replied and was at my home within 2 hours. He was friendly and knowledgeable and didn't try to upgrade or oversell their A/C units but suggested the best fit for my small 1000 feet bungalow. Although this was during a heatwave and very busy, they were able to fit me in 2 days later. The TwinTech crew installed a 1.5 ton Ducane A/C unit that is now running smoothly while maintaining a constant cooling temperature. The crew were very courteous, professional and efficient and I will definitely recommend TwinTech to family and friends. I much appreciated your great service.

We had a great experience. The guys who installed our a/c did a nice job. Cleaned up.
excellent crew, fast and efficient! Would call them again when I need a new furnace.
Professional, courteous and efficient, dont need to say more than that! Use them you will not regret it.
TwinTech was a pleasure to deal with from the estimate through installation. We replaced a 28 year old a/c unit with one recommended by TwinTech's sales representative Dave who took the time to go over the product with us and answer any questions. The warranty is for 10 years parts and labour and they will complete the registration for you. Installation was by Greg (owner) and Mitch and Spencer who were quick and efficient and left everything clean and tidy.
Very professional, from the sales consultation and inspection to the final installation. Met every expectations we had for the job. A local business with great client support. We highly recommend. Twintech is a blue chip! Thanks!

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!
