What We Install in Southern NH

Whole-Home Air Filtration

Media filters and electronic air cleaners can capture smaller airborne particles than a basic one-inch filter when the HVAC system supports the added resistance. We check the equipment and airflow before recommending an upgrade.

Air Filtration Services

Whole-Home Humidifiers

Bypass, fan-powered, and standalone ducted humidifiers that protect woodwork, instruments, and skin from dry New England winters. We size and integrate every unit with your HVAC system.

Humidifier Services

Whole-Home Dehumidifiers

During humid weather, some homes remain damp even while the air conditioner is cooling. A properly sized whole-home dehumidifier can work with the HVAC system to control moisture automatically at the selected setpoint.

Dehumidifier Services

HRV & ERV Ventilation

Energy Recovery Ventilators (ERVs) and Heat Recovery Ventilators (HRVs) bring fresh outside air in while recovering energy from outgoing air. They can be especially useful in tightly built or recently weatherized New Hampshire homes.

HRV & ERV Services

ecobee Smart Thermostats

ecobee smart thermostats offer remote-room sensors and flexible HVAC configuration. A $85 NHSaves rebate may be available when the thermostat is installed with a qualifying heat pump. Eligibility and the amount come from our shared rebate file.

ecobee & Nest Smart Thermostat Installation

A.J. LeBlanc Heating installs ecobee and Nest smart thermostats across Southern NH, including the wiring work required to make them compatible with your specific heating and cooling system. Not all smart thermostats are plug-and-play, especially with heat pumps and multi-stage systems. A smart thermostat can reduce unnecessary runtime through scheduling, remote control, and model-specific energy features. Actual savings depend on the home, equipment, settings, and how the thermostat is used.

Common Questions

Indoor Air Quality FAQ

Will a smart thermostat work with my heat pump?

Most smart thermostats are compatible with heat pumps, but the wiring is more involved. Heat pumps require an O/B reversing valve wire that standard thermostats don't use. A.J. LeBlanc Heating handles the wiring correctly so the system operates as intended.

Is a whole-home air filter worth it?

A properly selected whole-home filter can capture smaller airborne particles than a basic one-inch filter when the HVAC system has enough airflow capacity. The result depends on the filter, duct system, equipment, pollutant source, and how consistently the blower operates. We check the system before recommending an upgrade.

Do I need a dehumidifier if I have central A/C?

Central A/C removes moisture while it cools, but it may not fully manage humidity during mild weather or in a damp basement. If the home still feels clammy, we can measure the conditions and determine whether a dedicated dehumidifier is appropriate.

What is an ERV or HRV?

An Energy Recovery Ventilator (ERV) or Heat Recovery Ventilator (HRV) brings fresh air into your home while recovering the energy from the stale air being exhausted. They are particularly useful in tightly built or recently weatherized homes where natural air infiltration is low. We install Lifebreath and other HRV and ERV systems.
