ACE-Certified Assessment & Solutions for Upper Darby Homes

According to the EPA, indoor air can be two to five times more polluted than the air outside. In Upper Darby’s older housing stock, where row homes and attached dwellings dominate the streetscape, that gap can widen. Tighter construction, aging ductwork, and seasonal humidity swings all trap contaminants that standard HVAC maintenance won’t address on its own. McLoughlin Service Experts has served this community since 1965 and is part of the national Service Experts network, combining decades of local knowledge with the resources of a brand that’s supported homeowners since 1996.

Indoor Air Quality Solutions We Provide

Our ACE-certified technicians assess each home individually and recommend solutions matched to what’s actually happening in your air. We install and service five categories of equipment:

Air Filtration Systems: High-efficiency systems that help reduce allergens, pollutants, and contaminants circulating through your home.
Germicidal UV Lights: Advanced UV technology installed directly in your ductwork to address airborne microbes, including viruses, mold, and bacteria too small for standard filters to catch.
Humidifiers and Dehumidifiers: Whole-home systems that maintain optimal humidity levels, improving comfort and helping prevent issues caused by moisture imbalance in either direction.
MERV Rated Filters: Guidance on selecting the right furnace filter MERV rating for your specific system to support efficient operation and extend equipment life.
Ventilation Systems: Dedicated systems that bring fresh outdoor air in while exhausting stale indoor air, reducing contaminant buildup at the source.

Why Upper Darby’s Housing Stock Makes Air Quality Matter More

Upper Darby’s median home was built in the mid-1940s, and roughly 40 to 44 percent of its housing units predate 1940. Attached housing types, including row homes, duplexes, and townhouses, account for nearly 60 percent of local units. That combination creates specific indoor air challenges: airflow between shared walls is less predictable, original ductwork was designed before modern filtration standards existed, and infiltration points vary widely from home to home.

Delaware County summers can accelerate mold and dust mite activity. Cold winters can dry the air and concentrate combustion byproducts. The right indoor air quality solution depends on which of these pressures your specific home faces, which is why an assessment matters more than a one-size-fits-all recommendation.

Credentials That Back Every Installation

Our technicians hold ACE certification (Advanced Certified Expert), the industry’s recognized standard for HVAC competency. That credential shapes how we assess your home’s air quality challenges before recommending any equipment. Every technician is licensed, bonded, and insured, and all indoor air quality work is covered by the Service Experts Guarantee. McLoughlin Service Experts carries an average customer rating of 4.8.

Ongoing Maintenance for Your Air Quality Equipment

Filtration systems, UV lights, humidifiers, and ventilators all require periodic attention to perform as intended. Two membership options make that upkeep manageable.

The Service Experts Advantage Program provides new equipment with no down payment and includes parts and labor coverage, annual maintenance, and priority service scheduling. The Maintenance+ Membership covers annual tune-ups, priority service, and repair discounts for homeowners who already have equipment in place. Ask our team which option fits your situation when you call.

What’s Actually in Your Indoor Air

Most indoor air pollution comes from sources already present in the home. Dust, pet dander, mold spores, and pollen accumulate in living spaces and recirculate through ductwork. Volatile organic compounds (VOCs), gases released by cleaning products, paints, and building materials, add a chemical layer that particles alone don’t account for. Poor air quality can worsen allergy symptoms, trigger asthma episodes, and cause respiratory irritation even in otherwise healthy people.

Humidity plays a two-sided role. Excess moisture promotes mold growth and dust mite activity, both common concerns in homes without dehumidification during Delaware County’s humid summers. Air that’s too dry, typical during cold winters with forced-air heat, irritates skin and airways and can dry out the mucous membranes that help filter airborne particles. Managing humidity is as much a health consideration as it is a comfort one.

How Filtration, UV, & Humidity Control Work

MERV stands for Minimum Efficiency Reporting Value, a standardized scale that measures how effectively a filter captures airborne particles of different sizes. A MERV 8 filter stops larger particles like dust and pollen. A MERV 13 captures much finer particles, including some bacteria and smoke. Higher ratings aren’t always better, though: a filter with too high a MERV rating for your equipment can restrict airflow and reduce efficiency, which is why matching the rating to your specific system matters.

Germicidal UV light works differently from filtration. Rather than physically trapping particles, it disrupts the DNA of microbes as they pass through the treated section of ductwork, rendering bacteria, viruses, and mold spores unable to reproduce. The two approaches are complementary: filtration removes particles, UV addresses biological threats that filters miss. For humidity, the target range for indoor comfort and health is 30 to 50 percent relative humidity, a level that can discourage mold growth and dust mite activity while keeping airways comfortable.

FAQs We’ve Got Answers to Your Indoor Air Quality Services Questions

If an air freshener isn’t doing the trick, there may be microbes or contaminants nearby producing the unpleasant odor. They can be resolved with the sanitation properties of a germicidal UV light. They are particularly effective against odor-producing microorganisms.
Because carbon monoxide is colorless, odorless, and lethal in heavy concentrations, installing carbon monoxide detectors in central locations is the best way to alert you to its presence.
A carbon monoxide detector is like a smoke alarm, monitoring the air and notifying you if carbon monoxide levels are too high. If possible, you should have at least one detector near every bedroom on all floors in your home. Additional detectors can be placed near the kitchen, living areas or near combustion appliances. These detectors are best used in combination with our HVAC maintenance memberships, which keep your unit in good shape and may help you prevent carbon monoxide.
Prevention is the best place to start. A few safety precautions to take include:
- Don’t let your car idle in the garage. Cars are a significant source of carbon monoxide poisoning, so do not leave yours going in the restricted space of a closed garage. The same is true for gas equipment such as lawnmowers or snowmobiles.
- Don’t use ovens or grills as sources of heat. These appliances are safe when used right but can make carbon monoxide when used for an extended period in small spaces.
- Never operate a gas generator indoors. The fumes will have a much harder time dissipating.
- Have your chimney inspected by a specialist. This ensures chimneys and vents aren’t blocked and are connected appropriately.
- Confirm gas appliances are operating correctly, particularly your heater. You can ensure efficient, safe operation by booking routine furnace maintenance with McLoughlin Service Experts.
If carbon monoxide has been detected, you should immediately vacate the building and alert the fire department and utility provider. If a leak is discovered, you should then contact a trusted HVAC company for repairs.
Yes. Eliminating carbon monoxide should be a priority because of the danger it poses to your health and well-being. CO gas can be found in any U.S. home or commercial property, making safe ventilation and prevention strategies universally beneficial.
Initial symptoms such as nausea and fatigue are often mistaken as a result of the flu. But CO gas exposure can progress, potentially leading to confusion, organ damage, or even death. Other symptoms include:
- Headaches
- Dizziness
- Chest pain
- Vomiting
