How does the $75 AC diagnostic work?
We send an HVAC technician to your home to inspect your AC system. Using professional-grade tools and experience, we identify what’s causing the issue — whether it’s a failing part, a refrigerant problem, electrical issue, or airflow restriction. You’ll get a full explanation and repair options with no hidden fees.
What if nothing is wrong with my system?
If your system checks out fine, we’ll still walk you through everything we inspected so you know it’s running safely and efficiently. We never upsell or push unnecessary work — just honest, expert advice.
Is repair included in the $75 diagnostic?
The $75 covers a thorough system diagnosis. If a repair is needed, we’ll explain your options and provide upfront pricing before any work begins. There’s no obligation to approve repairs on the spot.
How long does an AC diagnostic take?
Most diagnostic appointments take 30–60 minutes depending on the issue. We often offer same-day service, especially during peak heat.
Are you licensed and insured?
Yes — all of our HVAC technicians are fully licensed, bonded, insured, and trained to service all major AC brands. We’ve been serving local homeowners since 2017 with top-rated service.
