When you replace your air filter, pick the right one for your furnace. Think about the filter’s MERV rating, size, and material. A good air filter can make your furnace work better, cut down on air filter problems, and lessen furnace maintenance needs.

- Reduced energy bills
- Minimized risk of air filter problems and furnace maintenance issues
By following these tips and keeping up with air filter care, you can make sure your furnace works well. This means your home stays warm and cozy.

Medium | 5-8 | 16×25 |
High-Efficiency | 9-12 | 20×25 |
Examining Your Furnace’s Pilot Light or Ignition System
The pilot light or ignition system is key to your furnace’s performance. A bad pilot light or ignition system can make your furnace blow cold air. This leads to less heat and higher energy bills.

Fixing these issues quickly is crucial. It prevents high costs, system damage, and safety risks like carbon monoxide or fires.
