Indoor Air Quality
The air inside your home should be cleaner than the air outside. We help make that happen.
In North Carolina, indoor air quality challenges include pollen, mold spores, dust mite allergens, crawlspace moisture, and VOCs from building materials. During peak pollen season, indoor concentrations can actually exceed outdoor levels in poorly filtered homes. Junior Collins HVAC assesses your home's specific IAQ issues and recommends practical solutions matched to your actual situation — not a one-size-fits-all product pitch.

Pro Tips for Homeowners
During NC's spring pollen season (March–May), keep windows closed and run your HVAC fan to filter indoor air. A MERV 13 filter captures 90%+ of pollen particles — a standard 1-inch fiberglass filter captures almost none.
Check your air handler coil for mold if you smell a musty odor when the system runs. NC's humid summers create ideal mold growth conditions on evaporator coils — a UV-C light installed on the coil eliminates this.
Crawlspace moisture is a significant IAQ driver in NC homes. A damp crawlspace introduces mold spores and elevated humidity into the living areas above — it's often the hidden source of persistent musty odors.
Your home should maintain 40–50% relative humidity year-round for optimal comfort and to inhibit mold growth. Above 60% consistently is a mold risk. A whole-home dehumidifier maintains this automatically.

FAQ
Common Questions
Does a standard air filter handle indoor air quality?
Standard 1-inch fiberglass filters are designed to protect the equipment — not to filter fine particles for health. They capture large debris but do little for pollen, mold spores, bacteria, fine dust, and allergens. Upgrading to a MERV 13 media filter or adding a UV system is where real IAQ improvement begins.
What's the most common IAQ problem in NC homes?
In our experience, high indoor humidity and the resulting mold growth — especially on evaporator coils and in crawlspaces — is the most prevalent issue. NC's summer humidity creates persistent conditions for mold. Pollen filtration is a close second during spring.
How do I know if I have a crawlspace moisture problem?
Look for: musty odors in the home (especially in first-floor rooms), visible condensation on floor joists or ductwork in the crawlspace, soft or springy subfloor, or visible mold on wood in the crawlspace. We assess crawlspace conditions as part of our IAQ evaluation.
What's the difference between an air purifier and a UV light?
UV-C lights neutralize biological contaminants (mold, bacteria, viruses) on coil surfaces and in the airstream using light energy — no chemicals, no ozone. Air purifiers may use filtration, UV, ionization, or a combination. We recommend UV-C coil lights for most NC homes because coil mold is so prevalent in our humid climate.
How much does indoor air quality equipment cost?
UV-C coil light systems typically run $300–$600 installed. Whole-home dehumidifiers run $1,000–$2,000 installed depending on capacity. MERV 13 filter upgrades are the most affordable option — typically under $200 for the filter housing modification. We'll assess your situation and recommend what provides the most benefit for your home and budget.
Can my HVAC system handle a MERV 13 filter without problems?
Most modern systems handle MERV 13 media filters well — but they need to be changed on schedule (every 3–6 months, not annually). A MERV 13 filter that isn't changed regularly becomes more restrictive than a standard filter and can cause the same problems as a clogged filter: reduced airflow, coil freezing, and system strain.
