Helpful HVAC information
What to know before your service visit.
Before you request service
Check that the thermostat is set to the right mode (heat/cool) and temperature.
Check for a tripped breaker or a switched-off furnace/air handler service switch.
Look at the air filter — a heavily clogged filter can restrict airflow.
Note any sounds, smells, error codes or water around the equipment.
What to expect at the visit
A technician reviews the symptoms you described.
The system is inspected and the likely cause explained.
Options, scope and any costs are discussed before work is agreed.
Ask questions — next steps should be clear before anyone leaves.
Seasonal maintenance tips
Replace or clean filters regularly; many 1″ filters need changing every 1–3 months.
Keep outdoor units clear of leaves, snow and debris (about 2 ft of clearance).
Keep supply and return vents unblocked by furniture or rugs.
Consider a professional checkup before peak heating and cooling seasons.
Safety first
If you smell gas, leave the home and call your gas utility or 911 from outside.
Install and test carbon monoxide detectors near sleeping areas.
Don’t open sealed equipment panels or handle refrigerant yourself.

A few helpful answers
Before we visit.
Have a different question? Include it in your service request.
How do I schedule HVAC service?
Call (419) 428-2108 or send an inquiry. Sending an inquiry does not book an appointment; availability is confirmed by phone.
Which areas do you serve?
We serve Defiance and the surrounding area UNCONFIRMED. Include your service address so coverage can be confirmed before arranging a visit.
Can I request emergency HVAC service?
Yes—describe the urgency in your request or call the company to ask about availability. Emergency service availability is not guaranteed.
How do estimates work?
Tell us about the issue or installation you are considering. The scope, estimate process and any fees will be discussed and confirmed before work is agreed.
How can I change or cancel an appointment?
Contact the business directly, or use the appointment links provided with your confirmation when available. A new time must be confirmed.
How often should HVAC equipment be serviced?
A common recommendation is a checkup once a year for each system — heating before winter and cooling before summer. Your equipment manufacturer’s guidance may differ.
What information helps with a service request?
The type of system (furnace, heat pump, central AC, boiler), its approximate age if known, what you are noticing, when it started, and your preferred contact time.
Repair or replace — how do I decide?
Age, repair frequency, efficiency, comfort and cost of the repair versus a new system all matter. Ask for both options to be explained so you can compare.
