The Most Common Indoor Air Quality Problems We Solve On a Daily Basis

Dust And Allergens:

The desert environment of Phoenix can mean higher levels of dust and pollen in the air. Without proper filtration, these substances reduce your indoor air quality.

Car Pollutants:

Cars, nitrogen oxides, carbon monoxide, volatile organic compounds, and particulate matter. These substances can significantly deteriorate your indoor air quality in Phoenix.

Odor Problems:

Pet dander and other contaminants can sometimes cause unpleasant odors which circulate throughout the home or building.

Humidity Issues:

While Phoenix is quite dry most of the year, it does have a monsoon season where humidity levels can rise dramatically. Higher humidity levels can cause mold to affect your indoor air quality.

Integrity, Transparency & Honesty: The Cornerstones of a Reputable Indoor Air Quality HVAC Service

Before you commit to a service provider, ensure that their practices are aligned with these three pillars. Below are the questions you should be asking.

1. Are You Licensed And Insured?

A reputable service provider should have a valid state license and insurance. These are non-negotiable credentials that protect both the technician and you in case of any mishaps or accidents. Comfort One is a licensed and bonded contractor by the State of Arizona (License #:308978)

2. Do You Provide Written Estimates?

Transparency starts with a clear, written estimate that outlines labor costs, parts, and other fees. At Comfort One, we provide detailed and written estimates that leave no room for hidden charges. Before any of our indoor air quality services are performed, we discuss the estimate with you and wait for your approval.

3. What Kind of Parts Do You Use?

The quality of parts used can drastically affect the longevity and efficiency of your HVAC system. Nowadays many parts are produced in China and do not come with any type of warranty. We recommend to look for services that use American quality parts, just like we do at Comfort One.

4. Are Reviews And References Available?

Customer reviews and testimonials give you insights into actual customer experiences. They help you understand if the indoor air quality HVAC service provider walks their talk. We are proud of our 100% customer satisfaction rate and openly share our customer reviews. Read our Google reviews here.

5. What’s Your Turnaround Time?

When your HVAC system is not performing top notch, time is of the essence, especially in the Arizona heat and cold. Check how promptly the service can attend to your needs. At Comfort One, we’re committed to being “On Time, Every Time!”. Some of our reviews even say ‘Jessica was the only one to actually answer the phone.’.

A reliable HVAC service provider stands behind their work. Always inquire about warranty options for parts and labor. We protect all our indoor air quality services with robust warranty options, because your peace of mind is our commitment. We generally offer a 90-day labor warranty and 1-2 year warranty on parts under the premise ‘Love it or we fix it’.
