The dust on your surfaces keeps coming back faster than it should in Covina. Your energy bills have been creeping up without any obvious reason in Covina, CA. Someone in the household has had allergy or respiratory symptoms that are noticeably worse inside the home than outside in Covina.

The answer to that last question is almost always yes. And the answer to the first two is often much longer ago and much more than you would expect in Covina.
