What to Expect When Switching to a Heat Pump Unit

Posted On: March 26, 2026

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.



🌬️ A Different Way of Heating and Cooling

The first thing to understand is that a heat pump doesn’t generate heat like a furnace—it moves heat.


That means:


  • In winter, it extracts heat from outside air
  • In summer, it removes heat from inside your home

Because of this, the way your home feels may be slightly different.



🌡️ 1. More Consistent (But Gentler) Heat

One of the biggest changes homeowners notice is how heat is delivered.


With a furnace:


  • You get short bursts of very hot air

With a heat pump:


  • You get a steady flow of warm (not hot) air

This results in:


  • More even temperatures
  • Fewer hot and cold swings
  • A more comfortable overall environment

At first, some people think it’s “not heating enough”—but it’s actually working exactly as intended.



🔄 2. Your System Will Run More Often

Heat pumps are designed to run for longer periods at lower intensity.


So don’t be surprised if:


  • Your system runs more frequently
  • It stays on longer than your old furnace

This is normal—and actually more efficient.



💸 3. Changes in Your Energy Bills

Your energy costs may shift when you switch to a heat pump.


What to expect:


  • Lower overall energy usage in many cases
  • More reliance on electricity instead of gas
  • Greater efficiency during mild weather

Your exact savings will depend on:


  • Your home’s insulation
  • Your current system
  • Local energy rates in Ontario

❄️ 4. Cold Weather Performance (and Backup Heating)

Modern heat pumps are designed to handle cold climates—but Ontario winters can still be demanding.


Depending on your system, you may have:


  • A cold-climate heat pump that works efficiently in low temperatures
  • A backup heating system for extreme cold

This ensures your home stays comfortable even during the coldest days.



🔧 5. Installation May Vary by Home

Every home is different, so the installation process can look different depending on your setup.


You might experience:


  • Integration with existing ductwork
  • Installation of new indoor units (for ductless systems)
  • Electrical upgrades if needed

Most installations are completed relatively quickly, but proper sizing and setup are critical for performance.



🧹 6. Maintenance Is Still Important

Heat pumps are efficient, but they still require regular care.


Routine maintenance includes:


  • Cleaning or replacing filters
  • Keeping the outdoor unit clear
  • Scheduling professional tune-ups

The good news? Maintenance is typically straightforward and helps keep your system running efficiently for years.



🌬️ 7. Improved Comfort and Air Quality

Many homeowners notice a difference in how their home feels—not just in temperature, but in air quality.


Benefits can include:


  • Better airflow
  • Reduced humidity in summer
  • Cleaner air when filters are maintained

This creates a more comfortable living environment year-round.



🔊 8. Quiet Operation

Heat pumps are generally quieter than traditional HVAC systems.


You may notice:


  • Less noise during operation
  • Smoother startup and shutdown
  • Quieter outdoor units

This is especially noticeable if your old system was aging or loud.



⚠️ 9. A Short Adjustment Period

Switching to a heat pump can take a little getting used to.


Common adjustments include:


  • Trusting the system’s steady operation
  • Avoiding frequent thermostat changes
  • Understanding that “warm” air won’t feel as hot as a furnace

Once you adjust, most homeowners find the comfort level is actually better.



🌱 The Benefits Become Clear Over Time

After the initial transition, the advantages of a heat pump really start to stand out:


  • Lower energy consumption
  • Consistent comfort
  • Year-round heating and cooling
  • Reduced environmental impact

It’s not just a new system—it’s a different, more efficient way to manage your home’s comfort.



🏡 Final Thoughts

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.

by Dorothy on Twintech Heating and Cooling

Had furnace and air conditioning unit put in. They did an excellent job great price and everything clean as can be, I was very pleased

by Barry on Twintech Heating and Cooling

All winter I have had an issue with very little heat reaching the 2nd floor of our home. After this past winter ended I decided to look into this. I found Twintech Heating and Cooling on line and started the process. After explaining my problem I had a call form Twintech and the tech came out and walked through things with me. The problem was the heating vent pipe had been dropped down in size by someone years ago causing little heat reaching the 2nd floor. Further into checking out the older furnace and AC they found a few things not properly installed by the last install of the old furnace and also that the AC was on it's last legs. I asked for a quote and waited a few days and we decided to go ahead with Twintech. They called a few days before to set up an installation time and date. The day of the install the guys were a half hour early which was a plus. The day of the install was great, the guys worked away removing the old furnace and AC.After which they installed the new furnace and AC. After they cleaned up the basement with all their tools and scrap metal etc. they came back inside to walk thru what they did. They also tested both the furnace and cooling systems to make sure everything worked and I the customer was happy. I now have heat on the 2nd floor for next winter. The guys from Twin tech were very professional. Their work habits and knowledge of the job was excellent. Their workmanship was just excellent, it was just up there with my standards as a homeowner. I am very pleased to have chosen Twintech for my new furnace and AC.. If I had to rate this experience with Twintech this company is a 10 in my books.Product,workmanship and customer care says it all.

by Craig in Whitby on Twintech Heating and Cooling

I called Twintech during the Covid 19 crisis because our furnace was broken and it was still very cold during the nights. Dave answered all of my questions by phone but wanted to come have a look but only if our family felt comfortable having someone visit during the uncertainty surrounding the pandemic and was able to attend that very same affternoon.

He was very courteous and informative but most importantly he respected his and our safety by wearing medical gloves in our home and maintaining proper physical distancing. He reviewed the various options of the products that suited our needs going over not only price but quality of workmanship, warrantees and where the product was manufactured which were all important factors in making such a large purchase. You could tell that Dave had been in this industry for a very long time.

The installation was done by a fine young gentleman the very next day and we now have a toasty warm home to ride out this crisis in while humming along at 96% efficiency!

I would recommend this very professional, small family business for anyone in need of HVAC equipment or maintenance.

by Lucy in Markham on Twintech Heating and Cooling

My special thanks to Twintech teams! They had replaced my furnace and A/C, and installed a new humidifier for me 2 weeks ago. Dave, the sales manager, not only provided me with an honest quote on the best HVAC products with best quality and warranties, he also arranged portable heaters for me and sent supporting docs to energy company for energy audit. Above and beyond service!

Greg, Grant, Mitch had worked tirelessly and professionally to perform the HVAC installation. They worked with professional tools, and performed proper measurement readings after installation. They are very patient with all my questions, and very pleasant to communicate.

Great work guys! This company sure knows their products and they stand behind their services. My home comfort level has improved! I am glad that I can support an ethical and honest local family business.

by ddame on Twintech Heating and Cooling

Professional, flexible on price and delivered on time...well done. All you can ask for when getting a new furnace.

by nicole.el.thorn on Twintech Heating and Cooling

The work was done quickly and professionally. Workers were really polite and easy to work with.
Product works great!

by Gary in London on Twintech Heating and Cooling

Furnace broke down on a Wednesday, shopped around for prices and Friday Twintechs name came up from a referral from my wife's work. Called Dave 11 am, he came over around 1 pm. Gave me a very good price, I accepted. The guys were there two hours later to take the old furnace out and install the new one. All finished by 6:30pm. Finally heat.
They were very pleasant and helpful. As a result we are doing our A/C later this year with this company.

by Shawn L in Whitby on Twintech Heating and Cooling

After some extensive research, we settled on Twintech for our new furnace. The service - from Dave's initial visit - through to the installation was absolutely fantastic.

Dave was super-patient with our many questions, did not try to "up-sell" us into buying things we don't need, knowledgeable, friendly and all-around an excellent Advisor.

I've forgotten the names of the installers but they were superb as well. They showed up on-time, did all the work with no mess or intrusion, removed the old furnace and installed the new one in one day; all with no impacts to our day-to-day life.

I cannot recommend Twintech enough, especially over any of 'bigger guys' who tried to sell us a bunch of thing we don't need. Twintech were fantastic and my wife and I are very pleased with our purchase.

by Stephen from Pickering on Twintech Heating and Cooling

From the minute I met Dave and discussed my new furnace needs I knew I was in good hands. He was patient, knowledgeable and very professional through the quotation process.

Grant and Greg did an outstanding job on the install. They did a great job of explaining the defects with my old furnace. The quality of the installation was excellent and the attention to detail was on another level. The old adage “You get what you pay for” couldn’t be more true as I feel I received great value, skilled expertise and high quality customer service. I highly recommend Twintech for all your heating and cooling needs.

by Arthur on Twintech Heating and Cooling

Glad to have found a not-too-big local firm that provided the needed expertise, quality workmanship, and competitive pricing as well. In and out in one day, removed the old units, did a nice job installing all of the new units, and left no debris. Even have a service contract that far outshined the big company offerings. Would definitely recommend them.

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!
