Emergency Service
A-1 Heating, Air Conditioning & Electric installs and services whole-home indoor air quality systems for homes across Meridian, Boise, and the greater Treasure Valley. From HEPA air purifiers and air scrubbers to whole-home humidifiers and ventilation systems, every IAQ system we install ties directly into your existing HVAC ductwork so filtered, conditioned air reaches every room. As a 15-time Dave Lennox Award winner and Lennox manufacturer-direct dealer since 1956, A-1 Heating carries the full Lennox Healthy Climate indoor air quality product line, including the PureAir S air purification system that removes particles, allergens, and chemical vapors down to 0.3 microns. Every Lennox IAQ system freshens air without producing ozone, a toxic gas that some competing products generate as a byproduct.
Call (208) 343-4445 to schedule an IAQ assessment at your Meridian or Boise home.
Wildfire smoke is the Treasure Valley’s most acute IAQ threat. When fires burn across central Idaho, smoke settles into the Boise basin and pushes fine particulate matter (PM2.5) into homes even with windows and doors sealed. The Idaho Department of Environmental Quality regularly reports “Unhealthy” AQI readings in Boise and Meridian during peak fire months. Standard 1-inch HVAC filters cannot capture PM2.5 particles. Whole-home air purifiers with HEPA-grade or electronic filtration are the most effective residential defense, filtering particles down to 0.3 microns before the air recirculates through your home.
The Treasure Valley is one of the fastest-growing metro areas in the western United States. New homes release volatile organic compounds (VOCs) from paint, flooring adhesives, and cabinetry for months after construction. Older homes collect dust mites, pet dander, and pollen, with Idaho’s sagebrush and grass pollen seasons running from March through June. Whole-home air purifiers and activated carbon filtration systems reduce both particulate and chemical contaminants at the source, before they circulate through your ductwork.
Treasure Valley winters are cold and dry. Indoor humidity in Meridian and Boise homes can drop below 15% in January when furnaces run constantly, well under the 30 to 50% range the EPA recommends. At those levels, skin cracks, sinuses dry out, static electricity builds, hardwood floors shrink, and respiratory infections spread more easily. A whole-home humidifier installed in your HVAC system adds moisture to the heated air as it circulates, keeping every room in the target humidity range without portable units cluttering bedrooms and hallways.
Whole-home air purifiers install inside your HVAC ductwork and filter every cubic foot of air that passes through the system. They capture dust, pollen, pet dander, mold spores, bacteria, and smoke particles. A-1 Heating carries the full Lennox Healthy Climate air purification lineup:
The Lennox PureAir S is the top-tier option. It uses photocatalytic oxidation (PCO) technology to combat all three classes of indoor contaminants: particles, biological contaminants like mold and bacteria, and volatile organic compounds (VOCs) including chemical vapors from paint and cleaning products. The Carbon Clean 16 filter inside captures particles as small as 0.01 microns.
For homes that need strong filtration without the full PureAir system, Lennox Healthy Climate media air cleaners (the Carbon Clean 16, HC13, and HC11) offer tiered protection at lower price points. The Carbon Clean 16 is rated the number-one professionally installed whole-home media filter by a leading consumer testing organization. The HC13 targets virus and bacteria protection, while the HC11 is built for pet owners and everyday allergen reduction.
A-1 Heating also installs the Lennox Healthy Climate HEPA filtration system for hospital-grade particle removal and the Healthy Climate in-duct air purifier for homes that need targeted air cleaning without a full system replacement.
Air scrubbers go beyond standard filtration by actively sending charged ions or oxidizers into the air and onto surfaces to neutralize contaminants. They reduce airborne and surface bacteria, viruses, odors, and VOCs. A-1 Heating installs Lennox air scrubbers that integrate with your existing heating and cooling system. They’re a strong choice for homes with pets, cooking odors, or family members with compromised immune systems.
Lennox Healthy Climate ventilation systems bring fresh outdoor air into your home while exhausting stale indoor air, all without losing the heating or cooling energy you’ve already paid for. In newer, tightly sealed Treasure Valley homes, the air can become stagnant because there’s little natural infiltration. A-1 Heating installs two types: the Healthy Climate Heat Recovery Ventilator (HRV), which is well-suited for Idaho’s cold winters and recovers heat from outgoing air to warm incoming fresh air while controlling wintertime condensation, and the Healthy Climate Energy Recovery Ventilator (ERV), which transfers both heat and moisture for homes in climates with humid summers. Both systems exchange air continuously, recovering 70 to 80% of the energy from the outgoing air stream, and both freshen air without producing ozone.
Excess moisture creates the opposite problem: mold growth, musty smells, and dust mite proliferation. Basements, crawlspaces, and tightly sealed newer homes in the Treasure Valley can trap moisture during spring snowmelt and summer irrigation season. A-1 Heating installs two Lennox dehumidification options: the Humiditrol whole-home dehumidification system, which uses patented technology designed to work with premium Lennox equipment, and Healthy Climate whole-home dehumidifiers that work with all brands of heating and cooling systems. Properly dehumidified air feels cooler, so you can set your thermostat higher in summer and still stay comfortable. According to the U.S. Department of Energy, setting your thermostat back 7 to 10 degrees for 8 hours a day can save up to 10% a year on heating and cooling.
A whole-home humidifier mounts to your furnace or air handler and adds moisture to the heated air before it enters your ductwork. Unlike portable humidifiers that serve one room and need constant refilling, a whole-home unit maintains consistent humidity across every room automatically. A-1 Heating installs Lennox Healthy Climate whole-home humidifiers in two configurations: power humidifiers for larger homes that need active moisture output, and bypass humidifiers that use your furnace’s airflow to distribute moisture with no additional energy. For Meridian and Boise homes, this means relief from dry skin, nosebleeds, cracked woodwork, and static shocks throughout Idaho’s five-month heating season.
The Lennox Smart Air Quality Monitor tracks your home’s air quality in real time and provides alerts when pollutant levels rise. It connects to compatible Lennox HVAC systems and can automatically trigger air cleaning when it detects poor air quality. For Treasure Valley homeowners who want visibility into what’s happening with their indoor air, especially during wildfire smoke season, the monitor pairs with PureAir and other Lennox IAQ systems to activate filtration on demand rather than running continuously.
Lennox Healthy Climate UV germicidal lights install inside your HVAC ductwork or near the evaporator coil and use ultraviolet light to kill mold spores, bacteria, and viruses as air passes through. They don’t filter particles. Instead, they sterilize biological contaminants that can colonize your coil and ductwork. Lennox’s UV germicidal lights deliver the highest UV light intensity on the market. For homes where mold has been found around vents or on the evaporator coil, a UV germicidal system prevents regrowth at the source. A-1 Heating installs UV systems as a standalone upgrade or combined with a whole-home air purifier for layered protection.
Every indoor air quality system A-1 Heating installs ties into your existing heating and cooling equipment. These are not portable plug-in units. They mount inside or alongside your furnace, air handler, or ductwork and treat the air as it circulates through the system. When your HVAC runs, air passes through the IAQ system before entering your living spaces.
This matters for two reasons. First, a whole-home system treats your entire house, not just one room. According to the U.S. Environmental Protection Agency (EPA), Americans spend roughly 90% of their time indoors, and indoor air can contain two to five times the concentration of pollutants found outdoors. A system that treats every room through the duct network is more effective than a collection of portable units.
Second, professional installation ensures the IAQ system is correctly sized for your home’s airflow. An undersized purifier restricts airflow and forces your furnace or AC to work harder. An oversized humidifier can push humidity too high and create condensation problems. A-1 Heating’s NATE-certified technicians calculate the correct size based on your home’s square footage, duct layout, and existing equipment before recommending a system.
Every Healthy Climate installation is situational. It depends on the job type and how your equipment is set up, and the configuration can vary up to five or more ways. That is why we look at your system in person before we quote.
The right IAQ system depends on the problem you’re solving. A-1 Heating, Air Conditioning & Electric provides IAQ assessments for Meridian and Boise homeowners to identify exactly what’s affecting your air and which system addresses it. Here’s a practical starting point.
