Have you ever experienced a furnace breakdown during the coldest day of winter? If you have, you know how frustrating and inconvenient it can be. Not only does it leave you and your family in the cold, but it also means unexpected expenses for furnace repair.

As homeowners, we all want to save money whenever possible. However, when it comes to furnace repair, cutting corners or making mistakes can cost you more in the long run. In fact, some common furnace repair mistakes could cost you an extra $1,000 or more.

To help you avoid these costly mistakes, here are some of the most common ones to watch out for: 

  1. Delaying Furnace Maintenance

Many homeowners need to pay more attention to regular maintenance for their furnaces, thinking that it's optional or they can save money by skipping it. However, this is one of the biggest mistakes you can make regarding your furnace.

Regular maintenance by experts similar to the ones at MieHi HVAC ensures that your furnace is running efficiently and helps catch any potential issues before they become major problems. By delaying furnace maintenance, you risk a breakdown or, even worse, needing a costly replacement.

2. Ignoring Small Issues

Have you noticed a strange noise coming from your furnace? Or it's taking longer to heat your home than usual. These may seem minor issues, but ignoring them can lead to bigger & more expensive problems.

It's important to address any small issues with your furnace as soon as they arise. This can save you from costly repairs or replacements in the future.

3. Attempting DIY Repairs

With so many online tutorials and guides available, trying and fixing your furnace yourself may be tempting. However, attempting DIY repairs can do more harm than good, especially if you need the proper knowledge and tools.

Furnaces are complex systems that require expertise to diagnose and repair properly. By attempting DIY repairs, you risk causing further damage or putting yourself in danger.

4. Not Checking Your Warranty

Did you know that most furnaces come with a manufacturer's warranty? This warranty covers the cost of certain repairs or replacements within a specified period.

Check your warranty to avoid paying for repairs that would have been covered. Make sure to read and understand your warranty to avoid any unnecessary expenses.

5. Skipping Professional Installation

If you're purchasing a new furnace, it must be professionally installed. While it may seem like an added expense, a proper installation ensures that your furnace runs efficiently and can save you from costly repairs in the future.

In addition, professional installers are knowledgeable about local building codes & safety regulations, ensuring that your furnace is installed safely and up to code.

6. Neglecting Filter Replacements

Another common furnace repair mistake is to need to replace your furnace filters regularly. Dirty filters can cause your furnace to work less efficiently, leading to potential breakdowns and higher energy bills.

Check and replace your filters every 1 to 3 months, depending on usage. This simple task can save you from expensive repairs in the future.

7. Overlooking Thermostat Issues

The thermostat is the control center of your furnace, and any issues with it can lead to problems with heating your home. Some common thermostat issues include faulty readings, incorrect temperature settings, or even a dead battery.

Make sure to regularly check and calibrate your thermostat to ensure that it's functioning properly. This can save you from costly repairs and keep your home at a comfortable temperature.

8. Skipping Professional Inspections

One of the biggest mistakes homeowners make concerning furnace repair is skipping professional inspections. While regular maintenance is important, a professional inspection can catch any potential issues that may have been missed.

Professional technicians are trained to spot and fix any issues with your furnace, ensuring that it runs efficiently and safely. Skipping these inspections could risk costly repairs or endangering your home and family.

9. Ignoring Unusual Sounds or Smells

If your furnace starts making loud or strange noises, it's important to address it immediately. These sounds could indicate various issues, from loose parts to a faulty motor.

In addition, any unusual smells from your furnace should not be ignored. A burning smell could mean an electrical issue or debris in the system, while a musty smell could indicate mold growth.

By ignoring these warning signs, you risk facing major repairs or even a furnace breakdown.


Taking care of your furnace and avoiding these common repair mistakes can save you from unnecessary expenses and ensure your home stays warm and comfortable during winter. Schedule regular maintenance with a professional  MieHi HVAC technician, promptly address small issues, and always read and understand your warranty. Remember, investing in proper care for your furnace now can save you from costly repairs in the future. So, always be proactive and mindful when it comes to your furnace!
