What We Install in Southern NH
Whole-Home Air Filtration
Media filters and electronic air cleaners that remove dust, pollen, mold spores, and other particles from your home's air. Far more effective than standard 1-inch filters across Southern NH homes.
Air Filtration ServicesWhole-Home Humidifiers
Aprilaire bypass, fan-powered, and standalone ducted humidifiers that protect woodwork, instruments, and skin from dry Southern NH winters. We size and integrate every unit with your HVAC system.
Humidifier ServicesWhole-Home Dehumidifiers

Lifebreath Energy Recovery Ventilators (ERVs) and Heat Recovery Ventilators (HRVs) bring fresh outside air in while recovering the energy from outgoing air. Important in tightly built or recently weatherized NH homes.

Not all smart thermostats are plug-and-play, especially with heat pumps and multi-stage systems.

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?
For most Southern NH homes, yes. A high-efficiency media filter or electronic air cleaner removes significantly more particles than a standard 1-inch filter, which helps people with allergies and keeps your HVAC equipment cleaner and more efficient.
Do I need a dehumidifier if I have central A/C?
Central A/C removes some humidity as a byproduct of cooling, but it cannot control humidity independently of temperature. If your home still feels clammy when the A/C is running, or if you have a basement that gets damp in summer, a dedicated Aprilaire whole-home dehumidifier is worth considering.
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 Southern NH homes where natural air infiltration is low. We install Lifebreath HRV and ERV systems.
