01Indoor air quality
Expert indoor air quality services in Sacramento — The air inside
isn’t guaranteed.
Sacramento homes are sealed tighter than ever, which traps everything in: VOCs, dust, smoke, dander, biological growth. Wildfire season layers on top.
We test particle and VOC levels first, then recommend the equipment that actually addresses what’s in your air. No ionizer-type cleaners — those produce ozone gas as a byproduct.
02When to call
Common indoor air quality issues in Sacramento — Symptoms in the house — cause in the air.
If you’re seeing any of these, an IAQ assessment will tell you whether it’s the air, the equipment, or something else.
Filter neglect
Filters not replaced in over a year — or no filters installed at all. Common in inherited or rental homes.
Persistent symptoms
Congestion, headaches, fatigue, or allergy-like symptoms that worsen indoors and ease outdoors.
Smoke or odors
Lingering second-hand smoke, cooking smells, or chemical odors that don’t clear with windows open.
Wildfire season
Smoke event in the area, and your HVAC isn’t pulling fresh air the way it should.
03Solutions
Indoor air quality solutions we install — Right tool.
Right contaminant.
Different problems need different gear. Particles, microbes, VOCs, humidity — each one has a specific solution.
- Solution 01
Air cleaners
Mechanical filtration that traps particles on filter fibers — dust, dander, allergens, smoke particulates.
- Solution 02
Air purifiers
CARB-certified low-ozone electrostatic and PCO units. Smaller particles, microbes, and VOCs.
- Solution 03
UV germicidal lights
Inline UV that disrupts bacteria and viruses at the DNA level so they can’t reproduce in your air.
- Solution 04
Humidity control
Add moisture in dry winters (fewer respiratory issues), pull it in humid spells (less mold risk).
- Solution 05
IAQ testing
Particle and VOC testing tells us what’s actually in your air before we recommend equipment.
- Solution 06
Filter installs & changes
Right-spec filter for your system, installed correctly. We can set you up on a recurring change schedule.
04Know your contaminant
Know your indoor air pollutants — Three categories.
Three strategies.
Gaseous (VOCs)
Carbon monoxide, sulfur dioxide, and Volatile Organic Compounds from dryers, gas stoves, paints, solvents, and modern building materials.
Particulate matter
Dust, dirt, soot, dander, smoke. The stuff your HVAC system circulates back through the rooms you live in.
Biological
Dust mites, bacteria, fungi, viruses — what tightly sealed homes accumulate without proper ventilation and filtration.

Honest Professional Opinion
“Our AC went out and another company came out and did a 5-minute diagnostic for $89 and then quoted us $20,000 for a new system. We got a second opinion from Alpha Mechanical who suggested we just replace the failing component instead of the entire unit at a reasonable price.”
Great Local Service
“I am a real estate professional who has dealt with many different heat and air companies over the years. I found Alpha Mechanical to be very impressive. Andrey is who I dealt with for an inspection of an HVAC unit. He was prompt and did a great job explaining things to the home buyer. I will definitely use this company again.”

“Andrey at Alpha Mechanical installed an adapter on heating/AC to give more airflow to our office. The second time we called, they serviced our outside AC unit that needed more freon — and they stopped by the same day we called. We really enjoyed the prompt service and their honesty.”
