When your system quits on a sweltering August afternoon or during a Nor’easter, you need hvac emergency repair you can trust. This guide explains what counts as an emergency, what to do before you call, and how our 24/7 team gets you safe and comfortable again in Greater Boston and Metro West. If you are dealing with burning smells, leaks, or no heat in winter, read this first, then call (617) 203-6133.
What Counts As an HVAC Emergency vs. a Next‑Day Repair
Not every breakdown needs a 2 a.m. truck roll. Use this simple filter:
- Safety risks. Treat these as emergencies.
- Burning smell from vents or equipment
- Sparking, tripping breakers, or smoke
- Natural gas or refrigerant odor, or a hissing line
- Water leaking onto ceilings, electrical panels, or finished floors
- Health and property threats.
- No heat during a freeze, or no cooling during dangerous heat
- Indoor humidity that causes ceiling leaks or mold risk
- Frozen evaporator coil and ice buildup on lines
- Comfort and efficiency issues. Often same‑day or next‑day.
- Short cycling, weak airflow, hot and cold spots
- Thermostat inaccuracies or Wi‑Fi connection problems
If you are unsure, call. Our dispatcher will triage symptoms in minutes and slot you for emergency or priority service.
First Steps You Can Take Before the Technician Arrives
A few safe checks can protect your home and may restore comfort faster.
- Power and breakers
- Check the HVAC breaker at the main panel. If it tripped, reset once. If it trips again, stop and call.
- Thermostat and settings
- Confirm mode, set point, and fan setting. Replace batteries if applicable.
- Airflow and condensation
- Replace a severely clogged filter. Look for water around the air handler or ceiling below it. If a safety float switch trips, do not bypass it.
- Outdoor unit
- Clear leaves or snow within two feet of the condenser or heat pump. Do not chip ice off coils.
- Water and gas
- If you smell gas, leave the home and call the gas utility and 911, then call us from a safe location.
If anything looks hazardous, do not troubleshoot. Our EPA‑certified technicians carry stocked parts to fix most issues on the first visit.
The Most Common Emergencies We See in Greater Boston
Boston housing has unique HVAC stressors. Triple‑deckers and brownstones often have tight returns and long refrigerant line sets. Coastal humidity and salt air speed corrosion. Here are the fast‑action issues we fix most:
- No heat during a freeze
- Failed igniter or pressure switch, inducer motor water intrusion, control board faults
- AC not cooling during a heat wave
- Failed capacitors or contactors, low refrigerant charge from a leak, seized fan motors
- Water where it should not be
- Clogged condensate drains, frozen evaporator coils that thaw and overflow, cracked drain pans
- Heat pump stuck in the wrong mode
- Reversing valve failure or defrost control issues
- Mini‑split head leaking or unresponsive
- Blocked drain lines, failed communication wiring, sensor calibration problems
We service central AC, heat pumps, ductless mini‑splits, packaged units and RTUs, air handlers, and evaporator coils across most major brands.
How We Triage and Fix Emergencies Fast
Speed without guesswork is the goal. Our process is designed for first‑visit resolution.
- Live triage and arrival window
- Our 24/7 team prioritizes true safety risks. You get updates by text with the tech’s ETA.
- Certified diagnostics
- We use pro‑grade meters and refrigerant tools to pinpoint failures. That includes leak detection, motor testing, and control board analysis.
- Upfront options
- You get a plain‑English diagnosis with good, better, best options and pricing before work begins.
- First‑visit repairs
- Service vehicles are stocked with common capacitors, contactors, motors, igniters, and drain materials to reduce return trips.
- Photo and video documentation
- We show you the issue, the fix, and any risks we see coming, so you can plan confidently.
Two hard facts that matter to your safety and performance: our HVAC technicians are EPA‑certified for refrigerant handling, and we maintain licenses that include Master Electrician, Master Plumber, and Sheet Metal. That combination is critical when electrical, condensate, and ventilation systems intersect in tight Boston homes.
Signs You Should Call Right Now
Call immediately if you notice any of the following:
- Electrical
- Breaker trips repeatedly, burnt smell, or visible arcing at equipment
- Odors
- Sulfur or rotten egg odor near fuel appliances, or chemical odor near refrigerant lines
- Water
- Active ceiling leak under an air handler or mini‑split cassette
- Ice
- Thick ice on the outdoor unit or insulated copper lines indoors
- Performance
- No heat below 35°F outdoors, no cooling during a heat advisory, or humidity over 60% inside
If in doubt, power the system off at the thermostat and call (617) 203‑6133 for rapid dispatch.
What It Typically Costs to Fix Emergencies
Every home and brand is different, but these ranges help set expectations. You will always receive an upfront estimate.
- Electrical components
- Capacitors, contactors, fuses, relays: common same‑day parts
- Motors and fans
- Indoor blower or outdoor fan motors vary by size and brand
- Controls
- Igniters, pressure switches, sensors, and defrost boards are often in stock
- Refrigerant and leaks
- Leak search, repair, and precision charging depend on access and system age
- Drainage
- Clearing clogs, replacing cracked pans, and adding safety float switches prevent future floods
When repairs stack up due to age or corrosion, we will also price a replacement path and note any utility incentives that could reduce total cost. Many Massachusetts households qualify for Mass Save rebates or 0% HEAT Loan financing on eligible upgrades.
Emergency Readiness for Homeowners: A Quick Checklist
Stay prepared, especially in older housing stock or homes with finished attics.
- Know where the air handler, shutoff switch, and cleanout are located.
- Replace filters every 60 to 90 days or as recommended.
- Keep two feet of clearance around outdoor units. After a snow, clear vents and louvers.
- Install water leak sensors under air handlers and near condensate pumps.
- Enroll in seasonal maintenance to spot failing parts before peak weather.
Why Mini‑Split and Heat Pump Emergencies Happen in Winter
Cold climate systems work hard during Boston winters. Ice, wind, and defrost cycles stress components.
- Defrost control faults can leave the outdoor unit encased in ice.
- Reversing valves can stick, so the unit heats poorly or cools when it should heat.
- Blocked drains in wall cassettes can overflow onto plaster or hardwood.
Our team repairs communication wiring, sensors, and drains, then calibrates thermostats and controls so each zone behaves as it should.
How Preventive Maintenance Prevents Emergencies
Most after‑hours calls trace back to issues a tune‑up could have caught weeks earlier.
- Dirty coils lead to freezing and water damage
- Weak capacitors cause no‑cool calls during heat waves
- Loose wires overheat and trip breakers
- Low refrigerant charge strains compressors
Seasonal maintenance checks airflow, electrical, refrigerant levels, safety controls, and drains. The goal is to eliminate gotchas before the first 90°F day or the first deep freeze.
Brand‑Agnostic Expertise Matters
We service Carrier, Trane, American Standard, York, Goodman, Bryant, Amana, and more. That matters because control boards, sensors, and communication protocols differ. Our experience shortens diagnostic time and keeps your costs in check.
Service Area and Local Insight
We cover Boston, Cambridge, Somerville, Newton, Medford, Malden, Waltham, Everett, Revere, and Dorchester Center. Older two‑pipe or tight return air designs are common here, so we plan repairs with airflow and code compliance in mind. That keeps your fix safe, quiet, and durable.
When Repair Is Not the Smartest Move
If a system has a severe refrigerant leak in a corroded coil, a failed compressor on an older unit, or multiple control failures, repair may only buy a season. We will show you the math and the risks, then advise you candidly. If a replacement makes sense, we help you tap available rebates and financing to lower the total out‑of‑pocket cost.

Frequently Asked Questions
Is no heat always an HVAC emergency in Boston winters?
Yes if outdoor temps are near freezing or below and you cannot keep indoor temps safe. Turn the system off if it smells burnt and call for 24/7 emergency repair.
What should I do if my AC is leaking water from the ceiling?
Shut the system off, place a container to catch water, and call immediately. A clogged drain or frozen coil can damage drywall and wiring if left running.
Can I keep running a heat pump covered in ice?
No. Shut it off and call. Ice indicates a defrost or airflow problem. Running it can damage the fan, coil, or compressor.
How fast can you arrive for emergencies?
We provide 24/7 live answer and dispatch. Arrival depends on call volume and distance, but true safety risks are prioritized for immediate response.
Do you service mini‑splits and central AC from any brand?
Yes. We repair ductless mini‑splits, central AC, and heat pumps from most major brands. We carry common parts and provide brand‑specific diagnostics.
