Proactive Plumbing and HVAC Maintenance for New Hampshire Homes
Proactive maintenance on a home's plumbing, heating, and cooling systems consistently produces the best outcome for the lowest total cost. Most major HVAC and plumbing failures are predictable. The water heater that floods the basement at 2 AM, the boiler that quits on the coldest night of the year, the AC that fails in the first heatwave: nearly all of these have warning signs that show up months earlier on a routine inspection.
At A.J. LeBlanc Heating, we work with NH homeowners across Manchester, Bedford, Concord, Nashua, Salem, and Auburn on practical proactive schedules. Below is what we recommend.
Monthly homeowner tasks
Things any homeowner can do, ideally with a reminder on the calendar:
- Check the furnace or air handler filter. Replace 1-inch filters at least every three months; check monthly. Media filters last six to twelve months.
- Look around water-using appliances (washer, dishwasher, water heater, ice maker) for any moisture, rust stains, or warped flooring. Catch a slow leak before it becomes a fast one.
- Test smoke and CO detectors. CO detectors are especially important in homes with fuel-burning equipment.
- Run rarely used fixtures. Run water through guest bathroom drains briefly each month so the P-traps stay full and sewer odors do not enter the home.
Seasonal tasks
Spring (before cooling season)
- Schedule an AC or heat pump tune-up before the first hot day. Late March through May is ideal.
- Rinse the outdoor condenser or heat pump coil gently with a garden hose, after disconnecting power.
- Test outdoor hose bibbs for leaks once the freeze risk has passed.
- Check the condensate drain on the indoor AC coil; clear any obvious algae or debris at the access port.
- Open windows briefly on a dry, low-humidity day to refresh indoor air.
Fall (before heating season)
- Schedule a heating system tune-up. Late summer through October is ideal.
- Drain and disconnect outdoor hoses. Shut off the hose bibb supply if your system has interior shut-offs.
- Test the operation of your sump pump if you have one.
- Inspect the chimney or flue if you have a fireplace, wood stove, or pellet stove.
- Replace CO and smoke detector batteries as you head into heating season.
- Confirm where your main water shut-off is located, in case of a winter pipe burst.
Annual professional service
Heating system annual service
A standard heating tune-up includes:
- Combustion analysis with measured CO and CO2 readings (especially important for oil systems)
- Heat exchanger inspection
- Cleaning and adjustment of the burner
- Inspecting and replacing the oil filter, nozzle, and pump strainer (oil systems)
- Testing safety controls, thermostat operation, and aquastats or limit switches
- Verifying expansion tank pressure and relief valve operation (hydronic systems)
- Replacing the air filter (forced-air systems)
Cooling system annual service
- Cleaning the outdoor condenser coil
- Inspecting and replacing the indoor air filter
- Checking refrigerant charge against manufacturer specs
- Measuring indoor coil and supply-air temperatures
- Verifying electrical connections, capacitor health, contactor condition
- Confirming the condensate drain is clear and the safety switch works
Water heater annual service
- Flushing the tank to remove sediment
- Testing the T&P (temperature and pressure) relief valve
- Inspecting the anode rod (replace every 3 to 5 years)
- Verifying combustion or heating element operation
- For tankless: descaling and verifying flow sensors and gas connections
Generator annual service (if you have one)
- Oil and filter change
- Spark plug and air filter inspection or replacement
- Battery test
- Full load test
- Verifying weekly self-test schedule and reviewing fault codes
Service contracts vs. one-off service
For homeowners who prefer not to think about scheduling, many HVAC contractors offer service contracts that bundle annual maintenance, priority service in emergencies, and a discount on repair parts. The math varies by home, but for households with multiple systems (boiler, AC, water heater, generator), a contract often pays for itself in service-call avoidance alone.

Frequently Asked Questions
How often should I schedule HVAC maintenance?
Annually for each system: heating in fall, cooling in spring, water heater in spring or fall. Generators also need annual service. Most homes do this through a single contractor that handles everything.
Is annual maintenance required for warranty coverage?
For most major brands, yes. Manufacturer warranties typically require documented annual professional service to remain valid. Keep service records.
What is the average cost of proactive maintenance?
Varies by system and contractor. A typical NH single-system tune-up runs $150 to $300. Multi-system service contracts often bundle several visits at a lower per-visit cost.
What happens if I skip annual service?
Equipment does not last as long, runs less efficiently, and is more likely to fail at the worst possible time. Most large failures we respond to (cracked heat exchanger, compressor failure, water heater leak) had warning signs that would have been caught during routine service.
Can I do annual maintenance myself?
Homeowner tasks (filter changes, visual inspection, sump pump testing) yes. Combustion analysis, refrigerant work, and safety control testing require licensed professionals.
