Is This You?

Your System Is Down. Here's What Happens Next.

Most HVAC emergencies have a single, fixable root cause — a failed igniter, bad zone valve, tripped safety, seized pump, or low refrigerant. An experienced technician can usually diagnose and fix the problem in a single visit. The key is getting someone there fast with the right parts.

FAQs

Common Questions

Don't see your question here? Call us — we're happy to talk through your situation before you commit to anything.

Call Us

What should I check before calling?

For no-heat: check thermostat settings (set to Heat, above room temp), your circuit breaker, and the emergency shutoff switch (red switch near the unit or at top of basement stairs). For a boiler, also check water pressure gauge — should read 12–25 PSI. For no-AC: check thermostat mode and replace your filter if it's been a while. If none of this fixes it, call us.

How fast can you get to me?

We prioritize emergency calls across our service area. Call us and we'll give you a real ETA based on current dispatch — not a scripted promise.

Do you charge extra for emergency service?

We charge a diagnostic/call fee for emergency visits, which we'll tell you upfront. It's applied toward the repair if you proceed. No hidden fees.

What if my system needs a part you don't have?

We'll tell you honestly, give you an accurate timeline for the part, and discuss temporary heating or cooling options if needed.

Should I repair or replace an old system?

If your system is over 15 years old and a repair would exceed 50% of replacement cost, replacement usually wins. We'll give you the honest number — not the one that's most profitable for us.
