Tucson dust gets everywhere, and most of what people try first — a better filter, a plug-in purifier — treats the symptom. The air in your house moves through your HVAC system, so that's where we look first.
If return ducts leak, they pull in attic and crawlspace air along with everything in it, and no filter at the air handler fixes that because the dust is entering downstream. We find where the system is drawing from before recommending equipment.
Filtration matters too, but the wrong filter can choke airflow and make a marginal system worse. We match the filter to what the blower can actually pull through it.
Sometimes, but often not. If the system is pulling unfiltered attic air in through a leaky return, the dust bypasses the filter entirely. That's worth checking before you spend money on filtration.
Yes. A filter more restrictive than the blower is designed for reduces airflow, which hurts cooling and can freeze a coil. The right filter is the best one your system can actually breathe through.
We diagnose the HVAC system — airflow, duct leakage, coil condition, filtration. Laboratory air testing for specific contaminants is a different specialty, and we'll say so rather than pretend otherwise.
A service call is $120, or $190 after hours, and that gets a technician on site to actually diagnose it. You'll know what any recommended work costs before we do it.
Call or text and we'll look at where your system is pulling air from.
