Can HVAC help with asthma and allergies in Tucson?

It can help with the part it controls: the air that moves through the house. Good filtration, sealed ducts and a clean system reduce the dust and particles circulating indoors. HVAC doesn’t treat asthma or allergies. For medical questions, talk with your doctor.

What goes into Tucson indoor air?

Desert dust is the common thread. The monsoon, June 15 to September 30, brings strong winds and dust storms along with extreme heat and flash flooding, and dust finds its way into filters, returns and attics. Pollen and smoke can add to it. Our guide to indoor air quality in Tucson covers sources in detail.

What helps the most?

  • A well-fitting filter changed on a regular schedule. Ask the pro what filter your system can handle, because a filter that is too restrictive can choke airflow. See the filter guide for Tucson dust.
  • Sealed ducts and return paths, so dusty attic or wall air isn’t pulled into the system. ENERGY STAR says a typical house can lose about 20% to 30% of duct air to leaks, a national figure.
  • A clean indoor coil and blower, which a maintenance visit covers.
  • Closed doors and good seals at windows in the worst dust.

Does duct cleaning help allergies?

Probably less than people expect. The EPA says duct cleaning has never been shown to prevent health problems, and it doesn’t recommend it on a fixed schedule. It suggests cleaning when there is substantial visible mold, vermin or excessive dust and debris in the ducts. See is duct cleaning worth it.

Are evaporative coolers a concern?

An evaporative cooler pulls outside air through wet pads. That means outside dust can enter the house. Tucson Water says hard water builds calcium deposits in evaporative coolers, and advises regularly changing pads and adding an in-line filter. During the monsoon, when dew points rise into the high 50s at the airport, a cooler also works less well. See swamp cooler vs AC.

Should you add an air purifier or ventilation?

Whole-home air purifiers and ERV or HRV ventilation are options. Ask a pro what suits your home and how it affects the system. See whole-home air purifiers and ERV vs HRV. Services: indoor air quality and duct cleaning. The Tucson HVAC hub lists areas we cover.
