Frequently Asked Questions
Do you service my specific neighborhood in Great Falls? Yes. We cover the entire 22066 ZIP code [1.31]. Our service vehicles are routed daily throughout Great Falls, from the custom riverfront properties along Georgetown Pike and River Bend Road to the acreage estates off Seneca Road, Beach Mill Road, and Springvale Road. Whether your property is located in The Reserve, Falcon Ridge, Black Riffles, or The Estates at Longwood, you are within our standard daily dispatch area and qualify for our full range of multi-zone repair, installation, and maintenance services.
Why is one zone in my house cold while the others are hot? This temperature imbalance usually points to a mechanical failure in your zone dampers, a broken zone control board relay, or a malfunctioning thermostat. Our technicians test the motorized damper blades to verify they are opening and closing properly and use electrical meters to trace communication signals between your thermostats and the main control board.
Can you service multiple separate heating and cooling systems during one visit? Yes. Our factory-trained field technicians are equipped to execute diagnostics, repairs, or preventative maintenance across multiple outdoor condensers, indoor furnaces, or ductless mini-splits on the same property during a single service call.
Do you offer flat-rate pricing or do you charge by the hour? We use upfront, flat-rate pricing. After conducting a thorough system diagnostic to pinpoint the exact failure, your technician will present a written explanation of the repair and the exact cost of parts and labor before any work begins—eliminating surprise diagnostic hours or hidden fees.
My large furnace is short-cycling. What does that mean? Short-cycling means your heating system is shutting off prematurely before reaching your thermostat’s set temperature. In multi-zone properties, this is commonly caused by restricted airflow from clogged filters, a fouled flame sensor, or a blocked pressure switch tripping safety limits. We run static pressure tests and check error codes to find the precise bottleneck causing the loop.
Do your repairs come with a warranty? Every paid repair executed by Falcon is backed by a 1-year workmanship warranty. If the replaced component fails or does not perform properly within 12 months, our team will return to resolve the mechanical issue at no additional cost to you.
How fast can you get a technician to my home? We reserve daily rapid-response dispatch slots specifically for active equipment breakdowns and no-heat or no-AC emergencies. Our team provides clear arrival windows and sends automated tracking alerts directly to your phone when your technician is en route.
Do you handle all types of heating and cooling systems? Yes. Falcon field technicians are factory-trained and certified to service all major brands, models, and heating and AC configurations. This includes traditional gas, electric, and oil furnaces, central air conditioning units, heavy-duty electric heat pumps, zoned dual-fuel hybrids, and ductless mini-split setups.
Can you fix my system on the same day as the visit? We resolve the vast majority of mechanical issues during the initial service call. Because our local fleet operates with vehicles fully stocked with diagnostic equipment and common original manufacturer (OEM) parts, we can replace components like failing capacitors, bad flame sensors, or blown control boards right on the spot without requiring a second trip.
Do you offer emergency services after regular hours? Yes. Heating and cooling failures rarely happen at convenient times. Falcon operates a dedicated 24/7 emergency service line to handle urgent system lockouts, extreme weather no-heat situations, and major electrical failures overnight, on weekends, and on holidays.
How do I know if I should repair or replace my system? If your equipment frequently drops mechanical lockout codes, requires repeated component fixes, or causes your energy bills to spike unexpectedly, a replacement is often the more cost-effective choice. We perform comprehensive load calculations and check major safety items—like the integrity of your heat exchanger—to give you a factual, data-driven report so you can compare the long-term value of a repair versus a system upgrade.
