Integrity, Transparency & Honesty: The cornerstones of a reputable HVAC installation 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 HVAC installations are started, we discuss the estimate with you and wait for your approval.
3. What kind of makes and models do you use?
The quality of makes and models used can drastically affect the longevity and efficiency of your HVAC system. Nowadays many cheaper systems are produced in China and do not come with any type of warranty. We recommend to look for services that use American quality systems, 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 HVAC installation 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.

When you need a new HVAC system, time can be of 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.’.
6. Do you offer a warranty?
A reliable HVAC service provider stands behind their work. Always inquire about warranty options for parts and labor. We protect all our HVAC installations with robust warranty options, because your peace of mind is our commitment. We generally offer a 2-year labor warranty and 10 year parts warranty under the premise ‘Love it or we fix it’.

Frequently asked questions about HVAC installations in Phoenix
1. How do I know it's time to replace my HVAC system?
If your current HVAC system is over 10-15 years old, requires frequent repairs, or is no longer providing consistent comfort, it may be time for a new HVAC system installation. Oftentimes a retrofit installation is sufficient. When we do retrofit HVAC installations, we always check your ductwork to ensure maximum lifespan and efficiency of your new system.
2. What type of HVAC system is best for Phoenix’s climate?
While central AC and heat pumps are generally effective for Phoenix's hot climate, the best choice depends on your specific needs and property constraints. We provide personalized solutions tailored to your home, budget and comfort.
3. How long does HVAC installation take?
Typically, retrofit HVAC installations can be completed within one day. Though complex new setups may require more time. Especially commercial projects that require more unit and bigger ductwork can take several days to a week.
4. Is financing available for HVAC installations?
Absolutely, we offer a variety of financing options in cooperation with our financing partner Synchrony. Transparency and honesty in pricing are key aspects of our service.
5. Do you offer any warranties or guarantees?
We provide a 100% customer satisfaction guarantee along with manufacturer warranties on most equipment. All of our new HVAC installations and retrofit installations come with a 10-year parts warranty and a 2-year labor warranty. For an additional fee, the labor warranty can be upgraded to 10 years.
6. Will a new HVAC system save me money?
New HVAC systems are generally more energy-efficient, which can lead to savings on your utility bills. This depends mostly on your energy-consumption behavior. If you maintain the same temperatures with your new system throughout the house, you should experience reasonable savings on your energy bills. Our EPA certified HVAC technicians can help you find a new HVAC system with the best return on investment.
7. How do I choose between a heat pump and a traditional furnace?
Heat pumps are typically more energy-efficient and are ideal for moderate climates like Phoenix. Furnaces, on the other hand, offer powerful heating for colder nights. We can help you assess which option is best for your needs.
8. Why should I choose Comfort One for my HVAC installation?
We offer American Quality Service with genuine care. As a family-owned & operated business, our commitment to your comfort is backed by integrity, transparency, and a 100% customer satisfaction guarantee.
