Questions & Answers
Frequently Asked Questions
Why is my furnace blowing cold air?
It may be a thermostat setting, a dirty filter, a faulty ignitor or flame sensor, or an overheating issue that shuts off the burners. Check your thermostat and filter first. If it is still blowing cold, call us for a diagnosis.
What are signs my furnace needs repair?
Watch for strange noises, short cycling, uneven heat, a burning smell that does not go away, or higher energy bills. A furnace that will not start or keeps shutting off also needs attention. Catching problems early can prevent a bigger repair.
Should I repair or replace my furnace?
If the repair is minor and the furnace is in good shape, repair usually makes sense. If your system is older and needs frequent or costly fixes, replacement may save money long term. We will give you an honest recommendation based on your system.
How soon can you fix my furnace?
Most appointments are available within 24 to 48 hours. For emergencies, we offer same-day service whenever possible. Many repairs can be completed on the first visit.
