Frequently Asked Heating Repair Questions
The most frequent culprits are clogged air filters, faulty ignition systems, malfunctioning thermostats, and worn blower motors or belts.

An annual fall tune-up catches most of these before they become a no-heat call.
We dispatch from two offices — Washington and Cedar City — so a technician is never far away. VIP Club members receive priority service scheduling, which moves them ahead of homeowners with similar needs. Call our office and we’ll give you the earliest arrival window we have open.
