Commonly Asked Questions

What are the benefits of an AZTech AC maintenance inspection?

There are many benefits to a maintenance inspection from one of our qualified technicians.  Our extensive inspection can save you up to 30% on your energy bills as we ensure efficiency and proper component compliance.  A maintenance inspection can extend the life of your HVAC (heating, ventilation, and air conditioning) system.  We work hard to improve the comfort levels in your home, by making sure your HVAC unit is operating at peak efficiency.  AZTech maintenance inspections can catch small problems before they become big problems, helping you save money and headaches.  But perhaps the greatest benefit of an AZTech AC maintenance inspection is the peace of mind that comes with knowing your HVAC system is operating properly, to keep you and your family comfortable all year long.

How long does an AZTech AC maintenance inspection take?

That’s a difficult question, because at AZTech we don’t have a one-size-fits-all inspection.  We personalize as needed.  Each home is different, and we take pride in testing and checking multiple elements of your HVAC system.  With that in mind, we don’t have an exact answer, if we find some problems we take the time necessary to diagnose and address  those issues and we won’t rush just to get to the next job or to meet an arbitrary timeline.  We’re here to ensure your system is operating effectively and safely, not to meet a daily quota.

How often do I need to change my filters?

In order to keep your HVAC system running as efficiently as possible, we recommend replacing your AC filters once every 30-45 days.  The dust and debris that collects will, over time, make its way into the system past the filters.  This, in turn, causes your system to work much harder – costing you more money.  At AZTech we also recommend that you have your ductwork cleaned every 3-5 years, or when you are replacing your HVAC system.

What does SEER mean when I am choosing a new AC system?

SEER stands for Seasonal Energy Efficiency Ratio. The higher the SEER rating is, the more efficient the HVAC system is; the more efficient the HVAC system is, the lower the operating costs are. Since 2016, the minimum standard SEER for new air conditioners is 14.  Most modern air conditioners have a SEER rating that ranges from 14 to 21.

What is the warranty on a new AC system?

When installing a new HVAC system for your home, you want to make sure it is registered correctly, just in case any issues arise in the future. Most new HVAC systems come with a 10-year manufacturer’s warranty on all major components. AZTech provides an additional 2-year labor warranty for all new installations. AZTech will also register your new system for all customers for the manufacturer’s warranty, unless you request otherwise.

What refrigerant is in a new AC system?

All newly installed AC systems will have R410a refrigerant in them. There are still older systems in use that have R22 refrigerant (commonly called Freon). The EPA has placed restrictions on R22 and is no longer allowing production or importation of it as of January 1, 2020. This limits the number of repairs possible on older systems.
