Simple Signs Your Furnace Needs Repair
A well-functioning furnace is essential for keeping your home warm and comfortable, especially during colder months.
However, furnaces can develop issues over time, leading to inefficiencies or even breakdowns.
Recognizing the signs that your furnace needs repair can help you avoid costly replacements and ensure your home stays warm.
Here are some common indicators that your furnace may need professional attention.
1) Unusual Noises
If your furnace starts making strange noises, such as banging, rattling, whistling, or screeching, it could be a sign of mechanical issues, loose components, or airflow problems.
Any unusual sounds should be inspected before they turn into serious repairs.
2 Weak or Uneven Heating
If some rooms in your home are colder than others or your furnace isn’t producing enough heat, it may be struggling due to clogged filters, ductwork issues, or a failing blower motor.
Inconsistent heating is a clear sign that your system needs maintenance.
3) Increased Energy Bills
A sudden spike in your energy bill without an obvious reason could indicate your furnace is working harder than usual.
This inefficiency may be due to a dirty filter, aging components, or failing parts that need repair or replacement.
4) Frequent Cycling
If your furnace is turning on and off frequently, it could be a sign of a malfunctioning thermostat, clogged filter, or improper airflow.
Short cycling puts stress on the system and reduces its lifespan, making prompt repair essential.
5) Strange Odors
A burning or musty smell when your furnace runs could mean dust buildup, electrical issues, or even mold in the system.
A persistent rotten egg odor could indicate a gas leak, which is an emergency requiring immediate attention.
6) Pilot Light Issues
For gas furnaces, a healthy pilot light should burn blue.
If it’s yellow, orange, or flickering, this may signal carbon monoxide issues or incomplete combustion.
Any changes in your furnace’s flame color should be inspected right away.
7) Poor Air Quality
If you notice an increase in dust, dry air, or allergy symptoms in your home, your furnace’s filter or ventilation system may be struggling.
Regular filter changes and maintenance can improve air quality and furnace efficiency.
Don’t Ignore Furnace Warning Signs
If you notice any of these signs, it’s best to schedule a professional inspection before small problems turn into costly repairs.
Regular maintenance and timely repairs will keep your furnace running efficiently and ensure your home stays comfortable all season long.
I was referred to Twintech by a neighbour and was not disappointed. Not only was the customer service excellent their workmanship was second to none. Greg and Grant work extremely clean covering the pathway to the furnace room, labeling the essential parts, left the area spotless and were efficient. They cleaned up the mess left by the previous installers (wiring, improperly installed AC coil, and gaps in venting etc). They also ran through the operation of the new furnace and gave me some maintenance tips. Greg and Grant are professional and all around good guys. I will definitely recommend their service to anyone without hesitation.
Very satisfied with service from Twintech , beginning with all the information provided by Dave , which helped make the decision much easier . Installation was very smooth & done on time as promised & cleanup was well done . Would definitely recommend this company & use them again for any future needs . Well done.
Twintech Heating & Cooling Inc. came in and replaced my 39 year old furnace with a beautiful Napoleon variable high efficiency furnace! Their work was efficient and professional and they were a pleasure to deal with, from sales to installation! I would highly recommend them.
After receiving numerous quotes to replace my old furnace and AC unit (which was 20 years old) I went with Twintech. Dave, in sales, answered questions professionally and promptly and worked diligently in order to secure my business. Installation was scheduled the week after and Greg and Peter showed up, as scheduled, and did a fine job installing both units. The site was left tidy and neat. I would highly recommend Twintech for your furnace and AC work.
I chose TwinTech because they installed my new furnace a few years ago and did a great job. When they installed my new A/C, they replaced all parts -- the copper pipes, the housing on top of the furnace and the wiring. (Apparently, the wiring for my old A/C was insufficient.) Their pricing was competitive. The sales representative came to see me within a few hours of my call. My new A/C was installed a few days later and I couldn't be happier with Twintech's professionalism and work. I would recommend TwinTech to any homeowner.
Had a great experience with this company. Great price and great customer service. You wont be disappointed with twintech. Discussed the job with Greg while he was installing who was extremely informative and obviously enjoys the work he does.
I needed my AC unit relocated due to upcoming landscape work. I reached out to the Twintech team through Homestars. Dave connected with me immediately to discuss the project and various options. We decided the best option was to mount the unit on the wall. Greg was in touch with me the same day as well and we scheduled the work for later that same week. This was a small job so I did not think I would get immediate attention. The Twintech team exceeded my expectations in every respect. They were very knowledgeable and friendly. The team arrived exactly on time on the scheduled day and worked efficiently to get the job done quickly. I would definitely use Twintech again for any Heating and AC projects.
I have used Greg Dainty for over 15 years in 3 different homes, for heating, cooling, pool heaters, appliances and bbq lines. Greg has always been so professional, friendly and the workmanship nothing short of fantastic. Greg has always discussed my options and fixing versus replacing, giving his honest opinion and what works best for me cost effective wise and long term. I have valued his opinion so much and have not trusted my gas needs with anyone since using him. I have also referred him to many of my friends and family and have always been so thankful with how well and quickly he looks after us all. I hold Greg in the highest regard and would recommend him to anyone with complete confidence!
Really nice honest guys. It was a pleasure to do business with a company that does exactly what they say theyre going to do! My basement was cleaner after they installed my new furnace and AC. Thanks again Greg and Grant and for doing such a great job.
5 star service!! I had twin tech install a high efficiency furnace and hot water tank at my home. I am taking time to write this review as a thanks for what I viewed as next level service that went above and beyond. Prior to installation they explained my specific options without pushy sales tactics and up front costs. Greg and Grant replaced a large portion of the duct work (built in their own shop) that had rusted over the years which resulted in a great looking job. It was a pleasure to work with people are passionate and take pride in their work. Following the installation they explained all aspects and maintenance of the new equipment. Products have worked flawlessly. Thanks again Greg and Grant! Highly recommend!!

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!
Amazing experience with TwinTech Heating & Cooling! Their team was professional, knowledgeable, and efficient from start to finish. They installed my new furnace quickly and left everything spotless.
