Book a Home Air Quality Assessment

What You Get

One visit. A complete picture of your home's air.

Most homes are never measured. In one appointment, you get real numbers, a professional HVAC inspection, and a clear plan. No guesswork, no pressure.

01

Air Quality Measurement

Calibrated sensors measure the pollutants that affect how your family breathes: fine particles, chemical vapors, carbon monoxide, CO₂, humidity, and more.

02

Full HVAC Inspection

Filter condition, ductwork, airflow room by room, system age and configuration. Your HVAC system is the engine of your air. We inspect all of it.

03

Scored Report & Plan

Your home scored across ventilation, filtration, and humidity, with a prioritized action plan walked through with you on-site. You keep the report either way.

"I started Baseline after testing my own home and finding radon at four times the EPA limit. My kids had been breathing it for years. Nobody had ever measured."

Bryan HestermanFounder, Baseline

Baseline is a local, founder-led company. The person who measures your home is the person whose name is on the license. No call centers, no commissioned salespeople, no franchise playbook.

We are a licensed HVAC contractor, but we lead with measurement: we test first, then recommend. If your air is in good shape, your report will say so.

"Bryan came out to take a look at our place and I was impressed. He actually measured what was going on (particulates, VOCs, CO2, all of it) and walked us through what it meant for our family, not just what to buy."

Raina B.Google review

"I never knew I was living in a not-so-perfect condition in my house until Baseline's Bryan walked in."

Parag S.Google review

"Most HVAC companies show up, sell you a system, and disappear. Bryan is building something completely different with Baseline Home Health."
