You can't see indoor air pollution, but it's real. Dust, pollen, pet dander, mold spores, bacteria, and volatile organic compounds (VOCs) accumulate inside your home—particularly in the sealed, insulated homes built today. Poor indoor air quality affects sleep, triggering allergies, asthma, and respiratory issues. At J&G Heating & Air Conditioning, we've been helping Lancaster County families breathe cleaner air since 1997. We install whole-home air filtration systems, UV germicidal lights, and humidity control equipment that work silently in the background.
When you’re investing in cleaner air for your family, the contractor matters as much as the equipment. Our experience, manufacturer certifications, and family-owned service all add up to one thing: an indoor air quality system installed right the first time, backed by people who’ll be here for maintenance and future service when you need them.
J&G Heating & Air Conditioning serves five communities across Lancaster County from our main office in Conestoga, PA. Each area receives the same quality installation workmanship, same-day emergency support if problems arise, and the same commitment to properly sized equipment and professional service.
Every indoor air quality improvement we do follows the same proven process — designed to deliver the right equipment for your specific air challenges, professional workmanship, and a system that performs from day one. Tap any step below to see exactly what happens.
We begin by asking about your concerns: allergies, asthma, dustiness, musty smells, dry air, or humidity issues. We perform a visual inspection of your current HVAC system, ductwork condition, and existing filter setup. For customers with health concerns, we may recommend air testing to measure particle count, mold spore levels, and humidity baselines. This data guides our recommendations.
During this visit, we also inspect your attic and basement to understand where equipment will be installed, check your electrical panel capacity, and ask about any past air quality issues. All of this data feeds into our equipment recommendation.
Based on the assessment, we design a solution. High particulate concerns call for a MERV 13+ media filter. Mold or bacteria concerns add UV germicidal lights. Humidity imbalances require humidifiers or dehumidifiers. Some homes need all three. We’ll present equipment options (brands, filter types, control systems) and explain the trade-offs: cost, maintenance, noise, and performance.
Before ordering, we confirm every detail with you: exact equipment specifications, installation location, ongoing maintenance requirements, and any ductwork modifications needed. This prevents surprises when the installation begins.
Before installing new filtration or UV equipment, we inspect your ductwork for leaks, blockages, or poor insulation. Air bypass (leaking from ducts instead of flowing through the home) wastes the filtration investment. We’ll seal significant leaks and address any obstructions. For UV light installation, we verify the placement location is safe and effective.
This step is critical for system effectiveness. Even the best air filtration equipment won’t work properly if air is bypassing the filter through duct leaks or if airflow is restricted by blockages.
Our technician installs the new equipment—filtration media, UV light assembly, or humidifier/dehumidifier—into your existing HVAC system. Connections are sealed to prevent air bypass. For UV lights, wiring is run safely to the furnace/air handler. Humidification lines are connected to the water supply (with proper shut-off valves). Every connection is pressure-tested and verified for leak-free operation.
Installation quality determines system performance. We take extra care to ensure all connections are sealed, wiring is safe and code-compliant, and water lines (where applicable) are properly installed with isolation valves.
The system is brought online and tested. Airflow is measured at multiple vents to confirm balanced distribution. Filter pressure differential is checked—if it’s already high, the filter is restrictive (higher efficiency but more maintenance). Humidity levels are monitored and thermostat controls are programmed. You’ll receive a full walkthrough: how to identify when filters need changing, how to adjust humidity setpoints, and how to monitor performance.
You’ll have a complete record of what was installed, serial numbers of all major components, and our contact information for any questions that come up during the first months of operation.
Most media filters need replacement every 6–12 months depending on use and indoor dust levels. We’ll send reminders before your filter is due. We can deliver filters to you or schedule a technician visit to replace them during a maintenance check. Many customers pair indoor air quality improvements with our HVAC maintenance plans to track filter needs and system performance together.
Ongoing support is what separates professional installation from DIY solutions. We’re here to answer questions, provide replacement parts, and ensure your system continues performing as designed.
