Questions, answered
Do you really offer 24/7 emergency service?
Yes. A real person answers our emergency line any hour, any day, and we dispatch a technician for true no-heat and no-cool emergencies as fast as possible.
How much does a repair cost?
We use upfront, flat-rate pricing. Your technician diagnoses the issue and gives you a firm price before any work begins, so there are no surprises on the bill.
How soon can you come out?
In most cases we offer same-day or next-day service. Emergencies are prioritized, and maintenance-plan members get priority scheduling.
Do you finance new systems?
Yes, we offer flexible financing on new installations with approved credit, so you can spread the cost of a new system over time.
What areas do you serve?
We serve Kennesaw, Marietta, Woodstock, and communities across Cobb, Cherokee, and North Fulton counties. See our service areas page for the full list.
Is regular maintenance really worth it?
Yes. Seasonal tune-ups lower energy bills, extend equipment life, prevent most breakdowns, and are required to keep many manufacturer warranties valid.
