"Roger is fantastic- he came out to fix my furnace, and I couldn't be happier with his service and his willingness to go above and beyond!"

"We woke up to our furnace not working, in December. They had a service person out here the same afternoon (within hours). They were able to diagnose, attain and install the proper part to get us back up and running. We have used this company several times with nothing but positive outcomes. Local company, responsive, and competitive pricing. Definitely recommend and will use again."

Frequently Asked Heating Questions

Here are a few answers to the most common questions we hear from our Springfield customers.

What are common warning signs that my furnace needs repair?
The most common signs are strange noises (banging, rattling, or whistling), inconsistent heating or cold spots, a sudden spike in your energy bills, or the system frequently turning on and off (called "short-cycling").
Should I repair or replace my aging furnace?
We'll always give you an honest, transparent assessment. Generally, if your furnace is over 15-20 years old, needs frequent repairs, and you're facing another high-cost fix, replacement is often more cost-effective. We'll help you compare the repair cost vs. the long-term energy savings of a new, high-efficiency system.
How often should I change my furnace filter?
This is the easiest way to help your system! We recommend checking it monthly and replacing it at least every 90 days. During the peak heating season, a monthly change is even better to ensure good airflow and efficiency.
Are annual tune-ups really necessary for safety?
Yes, absolutely. For gas furnaces especially, this is a critical safety check. Our technicians inspect the heat exchanger for cracks (which can leak carbon monoxide), check all gas connections, and test safety controls to ensure your system is running safely for your family or employees.
