Testing & Remediation from One Team, Under One Warranty
If something feels off in your home or business, the air you’re breathing may be part of the problem. Cornerstone Services provides indoor air quality testing for residential and commercial properties in Salem, NH and throughout southern New Hampshire and northern Massachusetts. What sets us apart is what happens after the test: if a problem turns up, we handle the fix. HVAC, electrical, plumbing, cleaning, and handyman work all run through the same team, under the same pricing and warranty structure.
Salem sits in Rockingham County, which carries an EPA Radon Zone 2 designation due to the region’s granite bedrock and glacial soils. That alone is reason enough for any homeowner to schedule a professional assessment. Add the EPA’s finding that indoor air can be two to five times more polluted than outdoor air, and the case for testing becomes hard to ignore.

What Professional IAQ Testing Identifies
A professional indoor air quality assessment goes well beyond what a boxed DIY kit can screen. Calibrated instruments measure the actual concentration of pollutants in your space and produce documented findings you can use for real estate transactions, insurance claims, or your own peace of mind.
Professional testing covers the full range of common contaminants:
- Mold spores and biological allergens
- Volatile organic compounds (VOCs) from building materials, finishes, and household products
- Carbon monoxide from combustion appliances
- Radon from soil and foundation entry points
- Particulate matter (PM2.5) and airborne dust
- Pet dander and other allergens
- Airborne bacteria and viruses
Radon and carbon monoxide are colorless and odorless. Without testing, there’s no way to know they’re present. Professional testing is especially recommended after water damage, a renovation, HVAC changes, or when a property is changing hands.
Signs Your Salem Home or Business May Have an IAQ Problem
Not every air quality problem announces itself with visible mold or a carbon monoxide alarm. Some indicators are subtler.
- Physical Symptoms: Persistent coughing, congestion, eye or throat irritation, headaches, or fatigue that ease when you leave the building are common signs. These symptoms often point to ongoing exposure rather than a short-term illness. Households with children, elderly residents, or anyone with asthma or a respiratory condition tend to feel these effects more acutely.
- Visible and Structural Signs: Musty odors, condensation on walls or windows, visible mold growth, or a history of water intrusion all suggest elevated biological contamination worth investigating.
- Situational Triggers: Recent renovations, new flooring or furniture, or changes to your HVAC system can spike VOC levels significantly. Tightly sealed, energy-efficient construction, common in newer New Hampshire homes, can trap pollutants that older, draftier buildings would vent on their own.
IAQ Solutions Cornerstone Services Delivers After Testing
Most IAQ companies hand you a report and stop there. We don’t. Once testing identifies what’s driving your air quality problem, our team handles the remediation, whether that means HVAC work, duct cleaning, electrical installation, or a combination of all three.
The EPA points to three core strategies for resolving indoor air quality problems: source control, improved ventilation, and supplemental filtration. Depending on what your assessment finds, we may recommend:
- Whole-home air purifiers to continuously filter contaminants from circulated air
- UV germicidal lights installed inside the HVAC system to destroy mold and bacteria at the source
- High-efficiency or HEPA filtration upgrades to capture fine particulate matter
- Whole-home dehumidifiers or humidifiers to hold humidity within the EPA’s recommended 30–50% range, where conditions for biological growth are less favorable
- HVAC duct cleaning to remove accumulated dust and contaminants that recirculate with every cycle
- Energy Recovery Ventilators (ERVs) or Heat Recovery Ventilators (HRVs) to introduce fresh air in tightly sealed structures without sacrificing efficiency

Frequently Asked Questions
How Often Should a Salem Home Be Tested for Indoor Air Quality?
For most properties, testing every three to five years is a reasonable baseline. Schedule sooner after water damage, a renovation, persistent occupant symptoms, or before buying or selling. If your home is tightly sealed or has an older HVAC system, more frequent testing gives you a clearer picture over time.
Can Poor Indoor Air Quality Affect My Heating and Cooling System?
Yes. Contaminated ductwork forces your HVAC system to work against buildup with every cycle, reducing efficiency and increasing energy costs. Addressing the source of contamination and cleaning the duct system often improves HVAC performance alongside air quality, making them worth solving together.

We do. Cornerstone Services handles indoor air quality testing and solutions for both residential and commercial properties in Salem and the surrounding region.
