Why Does My Furnace Need So Many Repairs?
If your furnace keeps needing repairs, it’s a sign that something deeper might be going on. Here are the most common reasons:
Lack of Regular Maintenance
Just like a car, your furnace needs routine checkups. Skipping annual inspections or filter changes can lead to dirt buildup, worn-out parts, and poor efficiency — all of which cause breakdowns.
Old Age
Furnaces typically last 15-20 years. If yours is nearing that range, parts start wearing out more frequently, leading to repeated repairs.
Improper Sizing or Installation
A furnace that's too small works overtime, and one that's too large cycles on and off too quickly. Both scenarios cause extra wear and tear on components.
Clogged or Dirty Filters
A dirty filter restricts airflow, making your furnace work harder. This strain can cause overheating, blower motor failure, or even a cracked heat exchanger.
Thermostat Issues
A malfunctioning thermostat can cause short cycling or make the furnace run longer than necessary, putting extra stress on the system.
Wear and Tear on Components
Blower motors, belts, bearings, and igniters naturally wear out over time. If multiple parts start failing, it may be more cost-effective to consider replacement.
Electrical Issues
Frequent on/off cycling or power surges can damage electrical components, leading to ignition problems, pilot light failures, or motor malfunctions.
Airflow Problems
Blocked vents, leaky ductwork, or even an improperly balanced system can cause uneven heating, making the furnace work harder than it should.
Pilot Light or Ignition Problems
Modern furnaces often use electronic ignition, which can fail due to sensor issues, dirt, or electrical problems.
Manufacturer Defects
Rare, but possible — some furnaces come with faulty parts or poor design that causes repeated failures.
When Should You Consider Replacing It?
If your furnace is over 15 years old, and repairs are becoming frequent and costly (especially major parts like heat exchangers or blowers), a replacement might save you money in the long run — plus, newer models are more energy-efficient.
Twintech promptly responded to request for quotation. They were thorough and helpful in explaining options. The quote was very competitive. Installation of new furnace was very professionally completed. Excellent work.
When our old oil furnace finally broke down we decided it was time to finally convert to natural gas and finally install central air conditioning at the same time. Knowing it was going to be a significant investment for us, we wanted to make the right choice. Twintech came highly recommended by a friend and we were not disappointed. From the first contact with the salesperson, until the final touches on the installation, we were so pleased with their service. Everyone from the company was so friendly, efficient and a pleasure to deal with. Best of all, the cost was very competitive. We would certainly recommend Twintech to anyone requiring HVAC work in their home.
Mitch from Twintech came out for our annual furnace inspection. We found him to be friendly, conscientious & he left the work area clean. We were also very impressed with the thoroughness of the job he did. This is the 2nd job weve had Twintech do for us & have been very happy with the results for each. We highly recommend this company. Thank you, Mitch, Dave & Greg.
Work was done on schedule, professionally, according to quote and with minimal inconvenience to building users. Very happy with the end result. The only area for improvement from my experience - need more timely quoting process.
The team was great! Very knowledgeable, professional and extremely helpful. A few days after install the unit didnt seem to be working, user error, but within minutes of contacting them..on a Saturday.. a tech was on the phone troubleshooting with us. I highly recommend Twintech for your cooling or heating needs. They stand by their products and a pleasure to deal with.
During the hottest week in the summer our old A/C decided to call it quits. I called Twintech Heating & Cooling after receiving a referral from a family member; came highly rated for being an honest, family-run business, who appreciates their customers. Dave was able to accommodate my hectic schedule and book a late evening appointment to walk through the specifics. Greg and Mitch arrived exactly on time a few days later, were very polite and friendly, and within a couple of hours had a new unit up and running. I also received a follow-up call to ensure we were happy with the Amana.
They were on time and very professional. I'm so glad I decided to go with Twintech, thanks!
Timely and appreciated - this was during the hottest days this year when our Air and Furnace way.
Efficient. Professional. No BS or overselling. What was promised, was delivered at a cost-effective price point.
Down to earth.
Professionally done and took care to cover all entry floors to the house for the installers to remove the old furnace and install a new furnace.
I also made recommendations of the tankless water heater that we had installed and items to address. We did not know they also installed tankless water heaters.
Price was not the cheapest nor the most expensive of my quotes. It's the quality of the installation that makes for a good AC system. The twins' knowledge & professionalism was evident in the small details:
Very clean work. Greg made sure that the refrigerant level & temperature were correct. They reinstall the insulation & vapor barrier around the wall. The outside electrical cords were secured to the wall. Proud to support this local company. Thank you.
