Heating Questions
Heating & furnace FAQ
Why is my furnace blowing cold air?
The most common causes are a tripped ignition, a dirty flame sensor, low gas pressure, a faulty thermostat setting, or a clogged air filter. Most are quick fixes — but a cold-air furnace can also signal a cracked heat exchanger, which is a safety issue worth diagnosing the same day.
How much does furnace repair cost in Grayson?
It depends entirely on the part and the problem — a flame sensor is a minor repair, while a blower motor or heat exchanger is far more involved. That's why we diagnose first, then give you a clear written price before any work begins.
Should I repair or replace my furnace?
As a rule of thumb, if your furnace is over 15 years old, has a cracked heat exchanger, or needs an expensive repair, replacement is often the smarter long-term call. We'll give you the honest math — not a sales pitch.
How often should I service my heating system?
Once a year — ideally in fall before heating season. An annual tune-up prevents most mid-winter breakdowns, keeps gas bills lower, and is often required to keep your manufacturer's warranty valid.
Is a heat pump worth it in Georgia?
Georgia's mild winters are nearly ideal heat-pump territory — efficient most of the year with a backup for the few cold snaps. They cool too, so one system covers both seasons. We'll size it correctly for your home and walk you through the energy-bill math before you decide.
