What Is Considered an HVAC Emergency in Hanover, NH?
Living in Hanover means dealing with real weather extremes. Our hot, humid summers can make you desperately miss your AC, and our frigid, snowy winters make a working furnace a matter of safety. When your home comfort system fails, it's not just inconvenient—it can be dangerous. So, what counts as a true emergency? If you have no heat during a winter storm when temps drop below freezing, that's an emergency. If your AC quits during a dangerous heatwave and you have elderly family members or young children at home, that's an emergency. Other urgent signs include smelling gas or a burning electrical odor from your furnace, your carbon monoxide alarm going off, or seeing a major leak of water from your indoor AC unit. In these situations, you need emergency HVAC service right away.
Local Climate, Housing & Equipment Challenges
Hanover's beautiful four-season climate is tough on HVAC systems. Our humid summers push air conditioners to their limits, while our cold, damp winters strain furnaces and boilers. Many homes in the Hanover Historic District and near the Dartmouth campus are older and have aging equipment that needs more attention. You might have a classic gas furnace or an oil-fired boiler. Newer homes in areas like Etna or along Lyme Road often use efficient heat pumps. No matter your system—central AC, a furnace, a heat pump, or a ductless mini-split—the local weather will test it. Dust and pollen in spring, humidity in summer, and road salt corrosion in winter all add wear and tear.
Common HVAC Problems Homeowners See in Hanover
We see the same issues pop up year after year in local homes. In the summer, a common call is for an AC that's not cooling. Often, it's a frozen coil from a clogged air filter or a failing capacitor. We've helped many families in the West Lebanon area get their cool air back during a July heatwave. In the winter, furnaces that won't ignite are a top problem. This can be due to a dirty flame sensor, a faulty igniter, or even a clogged exhaust vent from heavy snow. Another frequent issue, especially in our humid climate, is a clogged condensate line. This is the drain that removes water your AC takes from the air. When it clogs, water can leak inside your home, causing damage to floors and ceilings. We responded to one such call in a home near Storrs Pond, where a simple cleaning prevented major water damage.
Emergency HVAC vs Same-Day vs Routine Service
Understanding when to call for help is key. For true safety hazards—like a gas leak, CO alarm, or no heat in a freeze—you need emergency HVAC service immediately. For urgent but non-dangerous problems—like an AC failure on a hot day or a furnace that's making strange noises—same-day HVAC service is the perfect solution. We schedule these calls to get to you quickly during normal business hours. For everything else, like an annual tune-up, a strange smell you want checked out, or planning a system replacement, routine HVAC service is the way to go. This is how we help most homeowners in Hanover maintain their systems and avoid bigger problems down the road.
HVAC Service Cost Breakdown for Hanover Homeowners
We believe in being upfront about costs. For a standard service call during business hours, there is typically a diagnostic fee. This covers the technician's time to identify the problem. For emergency or after-hours calls (nights, weekends, holidays), there is an additional emergency call-out fee. After-hours labor rates are also higher, usually 1.5 to 2 times the standard rate. You pay for the parts needed for the repair, plus the labor time. For major projects like a new furnace installation, there may be permit costs from the town. As estimates for our area: a diagnostic fee might range from $89 to $129. An emergency call-out fee could add $75 to $150. A common repair like replacing a capacitor might cost $200-$400 total, while a more complex repair like fixing a refrigerant leak could be $500-$1,500. Every job is unique, and we provide a clear estimate before any work begins.
Signs You Need Immediate HVAC Service
- No heat during freezing Hanover winter weather.

Homeowner Safety Checklist (While Waiting for Help)
- If you smell gas, evacuate the house immediately and call your gas utility from outside.
- If your CO alarm sounds, get everyone, including pets, outside into fresh air and call 911.
- If it is safe to do so, turn off your HVAC system at the thermostat and at the circuit breaker.
- Keep away from any electrical components that are sparking or smoking.
- Move children, elderly relatives, or anyone with health issues to a safe, temperature-controlled location if possible.
- Never attempt to repair gas lines or high-voltage electrical components yourself.
Local Codes, Permits & Why Licensed Service Matters
In Hanover and throughout New Hampshire, HVAC work must meet strict codes for your safety. Furnace and boiler venting must be installed correctly to prevent carbon monoxide poisoning. Handling refrigerants in AC systems requires an EPA 608 certification—it's the law. For major work like installing a new furnace or heat pump, a permit from the town is often required. This ensures the installation is inspected and meets all safety standards. Hiring a licensed, insured HVAC service provider protects you, your home, and your family. It also ensures your system runs efficiently, saving you money on energy bills.
