Keeping Your HVAC System Free and Clear

After our heater stopped working altogether last winter, we realized that it might be time to consult with a professional. We called a family friend who is also an HVAC contractor and he came out right away to see what he could do. After taking a look at things, he told us that our vents were almost completely blocked with dust and dirt. He recommended a vent cleaning company to come out and help, and they removed loads of debris the next day with specialized suction tools. After that, our HVAC system ran almost perfectly. This blog is all about the importance of keeping your HVAC system free, clear, and functional.

A Handy Guide on Furnace Repair: Keeping Your Home Warm and Cozy

A faulty furnace can bring about significant discomfort, particularly when enduring the chilling winter season. While some furnace issues require professional help, there are others that you can troubleshoot and fix yourself. This guide will walk you through some common furnace problems and their DIY solutions.

Disclaimer: Always remember that safety comes first. If you're uncomfortable performing these tasks or if the furnace still doesn't work after your repair attempts, it's best to call a professional HVAC technician.

1. Check Your Thermostat

The problem might not be with your furnace at all. It could be a faulty thermostat causing the issue. If the thermostat runs on batteries, try replacing them.

2. Inspect the Circuit Breaker

If your furnace isn't turning on, it could be due to a tripped circuit breaker. Check your home's electrical panel and ensure the switch for the furnace is in the "on" position.

3. Replace the Air Filter

A blocked air filter can hinder airflow, putting unnecessary strain on your furnace and potentially resulting in overheating. However, if you have pets or allergies, you may need to replace them more frequently.

4. Clean the Furnace Flame Sensor

The flame sensor serves as a crucial safety device that automatically shuts down the furnace whenever it fails to detect a flame where it is supposed to be present. Over time, it can get dirty and send a false signal. To clean it, turn off the power to the furnace, locate the sensor (usually a thin, metallic rod located near the back of the furnace), gently remove it using a screwdriver, and clean it with a cloth or fine sandpaper.

5. Check the Pilot Light

For older furnaces with a pilot light, ensure the light is on. If it's out, follow your furnace's instruction manual to relight it. If the pilot light doesn't stay lit, it may indicate a problem with the thermocouple. This is a job for a professional.

6. Unblock Vents and Registers

Ensure that all your home's vents and registers are open and unblocked. Blocking these can cause an imbalance in your system, leading to pressure build-up and inefficient heating.

7. Regular Maintenance

Prevention is better than cure. Regular maintenance can help prevent many common furnace issues. This includes tasks like cleaning the blower, lubricating moving parts, checking the burner, and inspecting the heat exchanger for signs of wear or damage.

While this guide covers basic furnace troubleshooting and repairs, remember that not all furnace issues can or should be handled by homeowners. Furnaces are complex machines, and attempting to repair certain components without proper training can be dangerous or further damage the system. If the furnace still doesn't function correctly after trying these tips, or if you're dealing with issues like strange noises, persistent odors, or recurrent cycling, it's time to call in a professional.
