How We Respond to Emergency Calls
When you call us, you’ll speak with someone who understands how urgent your situation is. We’ll ask a few quick questions to understand what’s happening, then coordinate a technician to come out as soon as possible. Our service trucks are fully stocked, so we can diagnose and resolve most issues during the initial visit.
Our emergency HVAC process includes:
- A straightforward phone consultation to assess the situation
- Prompt arrival with the tools and parts needed for most common repairs
- Clear communication and updates throughout the visit
- Respect for your property and time, whether residential or commercial
Financing, Payment Plans & Warranty Coverage
We get it; emergencies rarely show up when the timing or budget feels right. That’s why we offer financing options and payment plans that make unplanned HVAC repairs easier to manage. If your system is still under warranty, we’ll walk you through what’s covered and help you make the most of it.

What Counts as an HVAC Emergency?
Not every issue is urgent, but some problems require immediate attention, especially in Florida’s climate. If your system has completely shut down, is blowing hot air in cooling mode (or vice versa), or is leaking refrigerant or water, it's time to act. We’ve handled everything from failed thermostats to burnt-out compressors, and we show up ready to get to the bottom of it.
We commonly respond to:
- Total system failures during extreme heat or cold
- Electrical burning smells or buzzing noises
- Refrigerant or water leaks near air handlers
- Commercial HVAC outages during business hours
- Broken thermostats or non-responsive units
- Furnace shutdowns during cold snaps
We also get calls about non-emergency issues that still need a quick look. If you’re unsure, give us a call and we’ll help you sort it out.

Not Just a Quick Fix—We’re Here for the Long Haul
While emergency calls are all about speed, we also take the time to explain what caused the issue and how to prevent it in the future. If your system is nearing the end of its service life, we’ll talk you through options for AC replacement or ongoing service plans, depending on what makes sense for your situation.
Need help beyond an emergency? Ask us about:
- Preventive AC inspections and maintenance
- Full HVAC system replacements
- Commercial HVAC upgrades or zoning adjustments
- Ductwork and indoor air quality solutions
