What to Expect When Switching to a Heat Pump Unit

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 Bill, Oshawa on Twintech Heating and Cooling

We are very happy with our new furnace. The service was excellent the guys worked 6 hours straight through and there was no mess at all they took the old furnace box’s etc with them they then explained everything to us they were very helpful and pleasant , when we need a new air conditioner we know who to call!

by Ken, Bomanville on Twintech Heating and Cooling

The crew from sales to installation was very professional and had great attention to detail

by Tracy, Pickering on Twintech Heating and Cooling

We couldn’t have been more impressed with Twintech - from our first service call with Mitch who took the time to thoroughly diagnose the issue with our furnace, to Dave who proposed a well thought out solution to meet our needs and finally Greg and team who acted quickly to install given we had no heat.


We did our due diligence by soliciting quotes from alternate providers and were shocked and disappointed by the aggressive and manipulative tactics used.


Twintech was honest in their approach, detailed in their product knowledge, reasonably priced, diligent in their follow-up and valued our business.


Well done Twintech! You made this a positive experience for us and our new furnace works beautifully!

by Skapoor, Ajax on Twintech Heating and Cooling

We recently purchased an Amana high efficiency furnace and humdifier through Twintech. The work was completed very professionally and the quality of the workmanship was high. There was some additional sheet metal work required to complete the installation, which they were able to complete themselves. Overall I am very pleased with the work and would highly recommend Twintech for a furnace replacement.

by Steve, Oshawa on Twintech Heating and Cooling

We were very pleased with every aspect of the work that was done. They were very professional and polite. They arrived when they said they would and job was completed on estimated time


We would highly recommend them to whoever needed a recommendation


We have a very large dog and they were very understanding and respectful of him being around

by Patrick, Toronto on Twintech Heating and Cooling

The blower on our furnace stopped working leaving us with a cold house. Dave from TwinTech responded immediately to our HomeStars service request. From beginning to end Dave was nothing but helpful, friendly and professional, he did a great job of walking us through the quote and scope of work.


The replacement of the furnace went smoothly. The Guys did a great job, everyone was very friendly and polite. There were no hiccups, or unexpected costs. The only surprise was they left the work area cleaner than it was before they started.


Was a great experience with the whole TwinTech team. Its been a couple of months since the new furnace has been installed and its working great!

by Ed, Whitby on Twintech Heating and Cooling

I heard about TwinTech when researching new furnaces at furnaceprices.ca. After contacting them about my broken down furnace, Dave came to my house the next day to assess my situation and requirements for a new furnace. He recommended one that had stainless steel heat exchangers which sold me since my previous furnace had issues with a rusted secondary heat exchanger that had to be replaced. Dave also set me up with an appointment with an energy audit company so that I could take advantage of a rebate to help improve the energy efficiency of my home and get some money back. A few days later, Greg, Grant, and Mitch came to install the new furnace and remove the old one. When delivering and removing the furnaces, they were very careful not to damage my floors and walls, and even laid out red carpeting to protect the floors. They were very friendly and professional. The installation was completed in the time they said it would take and they cleaned up their work areas. Within a week, Dave called to follow-up to see how everything was going. I have already recommended them to several friends and family members who may need new furnaces soon.

by Fred, Toronto on Twintech Heating and Cooling

Twintech did a great job, from Dave the Sales Rep to the Office staff and The Professional Technicians who did the installation. They were professional, courteous, knowledgable and informative. From beginning to follow up we were completely satisfied with everything. Thanks Again. Sincerely The Laytons

by Elle, Oshawa on Twintech Heating and Cooling

Great product, great service, great follow-up. The Twintech Heating and Cooling arranged removal of my existing oil tank and they installed the new gas furnace Amana (made in USA). I am very happy with the final result and support I received throughout the process. My thanks go to the entire Twintech team for their professionalism, great communication and follow-up.

by John & Linda, Ajax on Twintech Heating and Cooling

We've had Twintech provide us with work in the past, for an inground pool heater and required rough-in for a new gas stove. More recently they provided the same friendly, professional, timely and clean installation of our new furnace.

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!
