Dusty, dirty homes at any temperature can mean discomfort in Eureka. The air in today’s tightly-sealed, well-insulated homes can become stale as the same indoor air is circulated and re-circulated. In fact, indoor air quality is among the Environmental Protection Agency’s top 3 health concerns. The agency reports that with dust, pollen, pet dander, mold, skin flakes, chemical fumes, cigarette smoke, and more, the air inside your home can be 2-5 times dirtier than the air outside.

Although we usually can’t see them, air pollutants are all around us, already inside our homes, and waiting to come in from outside. From our yards to our kitchens, dangerous air pollutants threaten our home air quality. Plus, each season brings its own dangers, from mold in the fall and winter to pollens and high humidity in the spring and summer.

Fortunately, Aprilaire® offers a wide range of dependable air quality solutions, including humidifiers, ventilators, UV lamps, air purifiers, and electronic air cleaners that together can eliminate up to 99.9% of the pollutants threatening your home’s health.

Learn more about how the pollutants in and around our homes affect our indoor air quality and what you can do to improve yours.

What our customers are saying
Five-Star Customer Reviews

Evans Mechanical is an excellent service committed to customer satisfaction and guaranteed quality workmanship. Our water heater burst and they were very responsive. They sent a technician out the same day and it was determined the heater was beyond repair.

Everything was super professional. They showed up on time.kept me informed of what they were going to do and finished ahead of schedule. Work was impeccable! Highly recommended!

Martin R.

Excellent service from start to finish. Joe came out to give us an estimate on what we would need for a new furnace, never pressured us to buy the top of their line just giving us options on what we would need for our home. Then the date set for installation Thomas and Ryan came out on time and did a great job.

Kathi J.

All three technicians worked well together. They treated each other kindly and were thoughtful and courteous with me. They did a final and complete cleanup after the installment of my new heater. They were respectful of my home. I’m grateful I used this company.

Kathy T.

The installers are finishing up. We expect to have great results with the new furnace & the newly installed dehumidifier. We applaud the professionalism of the installers.
