Frequently Asked Questions

Why is my furnace acting up?
Short cycling, strange sounds, or inconsistent heating usually point to a mechanical problem. Higher utility bills and dusty air can also mean your system needs a check. Addressing these problems early can prevent major repairs later.

How often should I get furnace maintenance?
We recommend yearly maintenance before temperatures drop. That helps your system run efficiently when you need it most. During a visit, we clean the system, replace filters, and check for any hidden issues.

Why is my furnace blowing cold air?
Common causes include thermostat problems, dirty filters, or ignition failures. Our team can quickly find the issue and get your heat working again.

When should I replace my furnace?
If your furnace is 15–20 years old or breaking down often, a replacement may offer better performance and lower monthly costs. We’ll walk you through your options based on your home’s needs and your budget.

What does a furnace service include?
Our furnace services cover system inspections, thermostat checks, safety controls, and airflow analysis. We also look at fuel efficiency and duct performance to make sure everything works together.
