Furnace Repair : Common Problems & How to Fix Them


Most of us know that furnace repair and installation in Winnipeg isn’t exactly a weekend do-it-yourself project. Not only are winters here unforgiving, new high-efficiency gas furnaces are a lot more complicated than they used to be.

One mistake can leave you and your family without heat at a crucial time. This can also impact the cost of your homeowner’s insurance. When in doubt, make sure that only certified Winnipeg heating repair professionals make any changes to your home or commercial HVAC system. With that being said, it helps to know how to identify common furnace problems and which ones you can attempt to fix yourself.


What to Watch Out For

Some of the most common HVAC issues can include:


  • Problems with the Blower: If you turn your furnace on and hear it start, but the air never makes its way to the vents, you may have a blower problem. This can involve complicated motors and other parts that only a HVAC expert should try and navigate. The only remedy that you should try for this is to change the filters as they can sometimes block the airflow and impact switches within the furnace mechanism.
  • The Air Never Heats Up: This can have several causes such as problems with the pilot ignition or cracked heat exchange. Both of these fixes can cost a pretty penny and could be avoided with regular professional maintenance. 
  • Broken Thermostat: This could be either very simple, or very complicated. The DIY fix is simply to check and replace the batteries in the box. If this doesn’t work, it could indicate a problem with the thermostat’s sensor and the electrical wiring between the box and the furnace. It can be difficult to pin down this problem and it needs to be properly investigated by a professional.
  • High-Pitched Distressing Squeal: If turning your furnace on means covering your ears, you could be dealing with a broken, slipping or torn blower belt. Just like a vehicle, there are belts powered by small engines that cause your furnace to blow out air. If this belt breaks, so will the blower. This is always something that needs to be taken care of by a certified technician.
  • Inconsistent Heat: Check the pilot light. If it’s flickering unevenly or burning inconsistently, then you could have a gas flow problem. Again, this isn’t a problem that you should attempt yourself. Carbon monoxide is highly toxic and can be deadly when handled incorrectly. Professionals will have the tools and the knowledge to repair this safely.
  • Constantly Blowing: A furnace that never stops blowing can have a defective limit switch. If you aren’t absolutely sure what this is and what it does, then call in an experienced HVAC company to help.

First time using East Side Ventilation after searching for a reliable duct cleaner for a long time. Previously, had tried to hire another contractor but he failed to show two times and professionalism was questionable. From booking the appointment to the service personnel who came to do the job, to the efficiency of the work and the customer service/payment process at the end, working with East Side was an all-around great experience. Would definitely recommend and use again.

Madison Doerksen


Amazing service! I definitely recommend them!

Lisa Lab


By far the most reasonable prices and great service from the service manager to the service guy that came to fix our furnace. I would highly recommend them to anyone. I got a couple quotes and they were double of what I actually paid for with East Side Ventilation. Thanks again !!

Randall Dembowski


Great service all around! November 2022 my furnace was showing an error code and I thought I was looking at a huge expense. The technician did some troubleshooting and discovered a loose connection. Promptly fixed. Probably saved me $100s over others that may have just started replacing parts until it worked. This was my second great experience with East Side Ventilation

Trevor Winzoski


The technicians came into our home, they were very diligent, courteous and efficient at the duct cleaning! Highly recommend their service!!

David Ward-Nightingale


Had a Cold Climate Heat Pump and Air Handler installed in my home by East Side and it was a great experience. The salesman was knowledgeable and thorough, the installers were friendly and got the job done right, the admin team was helpful with Grant applications, and the product has been a HUGE upgrade from my old unit. All around great company to work with.

Erin Dupuis


The motor went on my furnace and Sam was here later on the same day I called. He went to get the new part and had it installed within a very short time-frame. I was thrilled with the service and would definitely recommend East Side Ventilation!

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value We just had our Furnace and Ducts cleaned and I just had to write up a review on Eastside Ventilation because it was amazing. From Dan D who accommodated a last min date change and set up the appointment to Scott and Paul who did everything right! A quick call 20 min before coming with a heads up. When they got here they introduced themselves right away to me and my wife and even our dogs liked them. They were Quick, Friendly professional, clean, covid friendly and bottom line good guys. Afterwards Scott gave me a recap of what they did what they found and even put in my new filter (one of those ugly accordion ones that take forever) then they both said it was nice to meet us and were gone... thanks guys and thanks Eastside.

This company did all the ductwork in our home when we built it 18 years go. They also installed our furnace and air conditioner. We hired them because the general contractor (Walter... can't remember his last name, sorry) who we hired to organize the building of our home said they have good pricing and do good work.
Anyway, Walter was right. And because of that, East Side Ventilation has been my go-to company any time I need anything done with my HVAC system for the past 18 years. The staff is professional, friendly, on time, and does excellent work. I highly recommend them. :) In case that loyalty makes it sound like I know them, I figure I ought to mention that I do NOT know the owners or staff on a personal level. It's just that I was really happy with their work when we built our home, and I see no reason to try anyone else and risk being unhappy with the workmanship. Some reviewers have mentioned that they couldn't get an exact quote ahead of time... I'm guessing that's because they bill based on how long it takes them to do the job, and they don't know that until they've done it. And I'm guessing they have enough business that they don't have to spend their time doing free in-home estimates anymore - and frankly, I don't blame them - I wouldn't do free in-home estimates either if I had enough business to avoid having to waste time on that. In any case, I've never worried about their pricing because like I said, they do good work and they're honest.

Chris came out to make it possible for our new dryer to be bottom ventilated. The existing hole was not in the right place. We were very impressed by his professionalism and attention to detail. He thought outside the box, anticipating issues the dryer installer might have and gave us extra ducting and a different elbow than the one we had. I had asked him to cut the duct flush with the bottom of the dryer, as that's what the installer said the night before, but Chris left it 1/4 inch higher as he didn't think the installer would be able to connect it easily otherwise. The installer came just as Chris was about to leave, and confirmed that it was a good thing that Chris left the extra margin of metal for him. Chris also said he added a brace to the ducting under the floor so that it was more solid than before. Our reno guy, who was also there doing work, took a look at it and said it looked really good. Chris was polite and prompt as well, and the man answering the phone, whom I talked to about 3 times, was always polite and helpful, giving me confidence. I would definitely recommend this company.

Needed emergency support for an air conditioner that stopped working on the weekend. The technician was able to come out the next day when most other places were closed all weekend. He was crazy knowledgeable and his initial thoughts on the problem was replacing a $35 part. Turned out he was right! I highly recommend them for AC repair and will look to try them out for furnace maintenance this fall.

S Adam


One of my daughter's and her husband just bought their first house. What better house warming gift than a duct cleaning... I know brilliant right!
I had the fine folks at East Side Ventilation clean my ducts many months ago and they did an honest great job. They were friendly and very professional. Their tech took the time to explain why the A/C was having a hard time cooling the second floor. This 100+ year old house was not built with A/C in mind. I asked my daughter how they were? She couldn't stop saying again how great they were. Definitely 5 star and 2 thumbs up!

Debbie Fedak


Called East Side. Came down the next day and fixed "immediately". Jason and I believe Manny, thank you so much. There is good service out there!!! Great work ethics, hard to find now days but we sure did. Merry Christmas to you all. Will rebook the cleaning and HRV balancing in January with you! Merry Christmas All. Brian & Debbie

Gerard and Daryl


Great service! Slight mixup in booking initially however when tech came he was quick, clearly knew what he was doing and fixed the issue. Would recommend them.

I have to thank east side and their technician Kevin for the service call he did to get my furnace back up and running in short order. Was very happy with the service and would definitely use their company again in the future.

Marshall Broeska


From my original request to book services for duct cleaning and HRV servicing the process was seamless and very effective. With colder temperatures upon us here in Winnipeg Manitoba it was perfect timing for duct cleaning and a HRV tune up. Booking was nearly instantaneous when speaking with the Service Manager Dave Megaw who had the duct specialists arrive within 36 hours of the request; both gentlemen, Russell and Scott, arrived promptly on time at 8 am and within an hour and a half and sound advice on when to perform next services they had completed the cleaning. Both were highly personable and moved efficiently through the house while maintaining absolute cleanliness. Within an hour afterwards the tech arrived for the HRV servicing. Again, working effectively assessing and sleuthing by process of elimination our home's heating system, it was deduced that a damper motor was in need of replacing. Not only was the problem solved but a temporary fix to allow colder air to flow into the HRV was suggested while the new motor was to arrive. Calls were made expeditiously to various source contacts for the replacement and within 15 minutes a new motor was located locally and to be installed in the next 24 hours. I am grateful for the team at East Side Ventilation for their quick action and collaborative approach to alleviating my concerns over excess moisture and our home's entire heating system. I will rest assured knowing the team has and will be there for any concerns related to the ventilation and air quality of my home. Sincere thanks to East Side. MRB.

Kirsten Belgioioso


Our furnace broke down and Eastside was very quick to come service it. The technician was friendly and professional. He took the time to break down our options for us. He explained what types of repairs were needed and also the option for a new furnace, if we wanted to replace it. There was no pressure to choose either route. We decided to replace the furnace and it was done very quickly. I would strongly recommend Eastside Ventilation if you need service on your ventilation system. You can feel confident you will be given honest feedback, a fair price and a quick turn around once you make your decision.

Roger Brown


Kevin replaced the steam canister in our Aprilaire Humidififier and was extremely professional and did an excellent job. I will use East Side Ventilation and Kevin for all of my heating and air conditioning work in future.

Bruce Waldie


East Side was very professional throughout the process. A different company tried to scare us with "all 5 parts of the heat exchanger are cracked". East Side gave us accurate details (with photos) and clear explanations. They came when they said they were going to come. They did exactly what they said they were going to do. Neat and clean. Very satisfied.

Douglas DeJong


East Side did a great job of installation. They found and corrected problems as they progressed in the installation. Thanks guys!

Peter Jacobs


From the recommendations to the quote and installation of a new 2 stage furnace, the whole process was represented by honesty and integrity. They never tried to sell me something I didn’t need. From the duct cleaning to the installation of the new furnace the representatives of EastSide Ventilation were personable, professional and willing to do whatever it takes to get the job done right. After service concerns were addressed immediately and completed in a timely fashion. I have no hesitation in recommending this company for their Home heating/Cooling/Ventilation needs. Thanks EastSide

Bram Strain


They truly went above and beyond to make sure all our needs were met. Very professional and stuck to fair quote. Very pleased and I recommend them.

Rick Fickes


I could go on and on, but the short version is this: THE most honest, trustworthy company I've ever dealt with. Dave in Service is outstanding; knowledgeable, prompt, upfront, and fair. I could not be happier. I continue to use them, and recommend them the instant anybody mentions looking for an HVAC company. 5 Gold stars!
