Emegency HVAC in
Worcester, MA
No heat at 2am? AC down during a heatwave? Seven Hills HVAC answers around the clock — a licensed technician, not a call center, every single time.
HVAC failures don’t wait for business hours, so neither do we. Seven Hills HVAC has answered emergency calls across Worcester County since 2009 — no heat on the coldest night of the year, no AC during a July heatwave, or a system throwing off a smell that just isn’t right. A licensed technician answers the phone directly, every time, day or night.
Our average emergency response time is around 60 minutes across Worcester, Shrewsbury, and Auburn. There’s no overnight, weekend, or holiday surcharge — the same flat-rate pricing applies no matter when you call, and you approve the cost before any work begins.
When to call for emergency HVAC service
Not every issue can’t wait until morning — but these usually shouldn’t wait at all.
No heat in freezing weather
A cold house in winter is a health risk, not just an inconvenience — especially for children or the elderly.
No AC during extreme heat
Prolonged heat exposure is dangerous, particularly for infants, pets, and anyone with a health condition.
Burning smell or smoke
Shut the system off at the breaker and call immediately — this is always treated as urgent.
Carbon monoxide alarm
Leave the house, ventilate if it's safe to do so, and call us and your gas utility right away.
Water leak causing damage
A leaking indoor unit or frozen line can damage flooring and ceilings quickly if left alone.
Sparking or electrical burning smell
An electrical odor from your system's controls or wiring is a genuine safety concern.
Total system shutdown
No response at all, even at the thermostat, often signals a control or electrical failure worth same-day attention.
Gas smell near the furnace
Leave the area, don't flip any switches, and call from outside — we'll walk you through the next steps.
Dealing with one of these right now?
Call us directly — a technician answers, no matter the hour.
