Gas piping comes in a variety of materials, but the most common one in households is black steel. The length of the gas pipes may also affect gas flow - the longer the pipe, the lower the air flow. When in doubt, hire a home service pro to get the job done.
We had an issue with our furnace not working properly and Boonstra came in for a same day appointment and diagnosed the issue as an issue with the igniter. I was told the part would need to be ordered and...
Mart offered an excellent service, advice, thorough job.
He came 3 times to check, diagnose issues, and service our boiler.
We'll certainly recommend for a professional and great job!
