INDOOR AIR QUALITY
CENTRAL MAINE
Maine's tightly built, energy-efficient homes trap indoor pollutants, allergens, and moisture. RG Mechanical installs whole-home air filtration, UV purification, ERV ventilation, and humidity control systems that make your home's air genuinely clean and healthy.
Air Quality Solutions
We install and service the full range of indoor air quality equipment — from simple filter upgrades to whole-home ventilation systems.
Whole-Home Air Filtration
High-efficiency media filters and HEPA filtration systems installed in-line with your existing HVAC system. Captures pollen, dust, pet dander, mold spores, and fine particles down to 0.3 microns.
UV Air Purifiers
UV-C light purification systems installed in ductwork neutralize bacteria, viruses, mold spores, and volatile organic compounds (VOCs) as air passes through your system.
ERV / HRV Ventilation
Energy Recovery Ventilators (ERV) and Heat Recovery Ventilators (HRV) bring fresh outside air into your home while retaining conditioned air energy — ideal for tight, well-insulated Maine homes.
Whole-Home Dehumidifiers
Standalone whole-home dehumidifiers control moisture levels throughout your entire living space, preventing mold growth and improving comfort during Maine's humid summers.
Duct Sealing & Cleaning
Leaky or dirty ductwork reduces air quality and system efficiency. We seal duct leaks and recommend professional duct cleaning when contamination is found during inspection.
Humidifiers
Whole-home humidifiers installed on your heating system maintain comfortable indoor humidity during Maine's dry winters — reducing static electricity, protecting wood floors, and improving comfort.
SIGNS YOUR HOME MAY HAVE
AN AIR QUALITY PROBLEM
Indoor air quality issues are often invisible — but they can significantly affect your family's health and comfort. These are the most common warning signs:
- Excess dust accumulating on surfaces shortly after cleaning
- Allergy or respiratory symptoms worse indoors than outside
- Stale, musty, or chemical odors inside the home
- Visible mold growth near vents or in damp areas
- Dry, irritated eyes or throat during winter months
- High humidity or condensation on windows in summer
- Recent home renovations generating dust and off-gassing
- Pets in the home causing dander accumulation
- Radon or carbon monoxide concerns in basement areas
- A newly constructed or very tightly insulated home
Maine Homes Are Tightly Built
Tighter homes may need planned ventilation to manage indoor pollutants and moisture. ERV and HRV systems provide controlled fresh-air exchange while recovering some heat energy. Evaluate ventilation using the home's construction, measured conditions, occupancy, and applicable standards rather than age alone.
Heat Pumps & Air Quality
Heat pumps include basic filtration in their indoor units, but for households with allergies, pets, or respiratory concerns, adding a supplemental whole-home filter or UV system to your heat pump installation significantly improves outcomes.

AIR QUALITY FAQ
Why is indoor air quality important for Maine homes?
Maine homes are built tight to conserve heat — which is great for energy efficiency but means less natural air exchange. Without proper ventilation and filtration, indoor air can accumulate pollutants, allergens, and moisture at higher concentrations than outdoor air. An ERV or HRV system provides controlled fresh air exchange without losing heat.
What's the difference between an ERV and an HRV?
A Heat Recovery Ventilator (HRV) is best for colder climates — it recovers heat from exhaust air and transfers it to incoming fresh air. An Energy Recovery Ventilator (ERV) also transfers moisture, making it better for humid climates or homes that need humidity control year-round. For most Maine homes, an HRV is the right choice for winter, though an ERV can be beneficial in summer too.
Can you add air filtration to my existing system?
Yes. We can upgrade your existing furnace or air handler with a high-efficiency media filter, install a UV purification system in your ductwork, or add a standalone air purifier. Most upgrades are compatible with existing HVAC equipment.
Do UV air purifiers really work?
UV-C light is effective at neutralizing bacteria, viruses, and mold spores as air passes through the system. Studies show properly installed UV systems in HVAC ductwork can significantly reduce airborne pathogens. They work best as part of a layered approach — good filtration plus UV plus ventilation.
How much does indoor air quality equipment cost?
Cost depends on the equipment, home layout, ductwork, electrical work, controls, and installation access. Request a written project-specific estimate and review current manufacturer information for proposed equipment.
