HVACR Replacement

HVAC systems are crucial for maintaining the ideal climate in commercial spaces, especially restaurants, where comfort and efficiency are paramount. Even the most robust HVAC systems need replacement eventually.

Turn to Sun State HVAC for your next commercial HVAC installation. We specialize in HVAC repair services and are proficient in setting up a wide array of systems suited to commercial environments. If you’re unsure whether it’s time to replace your restaurant’s HVAC system, consider these indicators:

  1. System Age: If your HVAC unit is over 10-15 years old, it’s probably time for an upgrade. Older systems are not as energy-efficient and are more likely to encounter operational issues.

  2. Repair Frequency: Constant repairs can be costly and disruptive, especially in a busy restaurant setting. Replacing an old system can be more cost-effective and less troublesome in the long run.

  3. Energy Expenses: An increase in energy bills is often a sign that your HVAC system is losing its efficiency, which can significantly impact operating costs in a restaurant.

  4. Temperature Consistency: Inconsistencies in temperature can affect customer comfort and food safety regulations in a restaurant. If your current system struggles to maintain a consistent temperature, it may be time to consider a replacement.

Locating skilled AC Repair Technicians can be challenging, and those proficient in this domain rightly command respectable compensation.

AC Repair

It is a well known fact that summer temperatures in our ‘Valley of the Sun’ often soar above 115 deg F and often cross above the 120 deg F area!   This kind of heat can feel devastating to those who have never experienced it before and many valley residents even experience forms of anxiety as a result.

Winters in the area are for the most part quite mild. Because of this newcomers to the Phoenix area valley often don’t realize how important it is to have a properly maintained well operating air conditioning system until the summer hits and we get the seasons first really hot weekend.   Read More…

Heating Repair

Dear friends in Phoenix, Scottsdale and Valley areas (service areas).   It is true that in the Valley of the Sun winters are mostly mild, in fact they are mostly gorgeous, full of sunshine with the smell of desert sage.

In fact normal winter temperatures rarely fall below the low 30’s, and sometimes into the high teens but even so, because of the area’s low humidity, 30 degrees can actually feel much, much colder and again when it is really dry you can feel bone-shivering chills even at temperatures up into the 40’s and above!  Read More…

HVAC Maintenance

Sun State HVAC has been the forerunner in HVAC maintenance services since it’s inception in 1979.  In fact we practically invented the whole HVAC preventative maintenance process before a  few other companies even realized the importance and value of HVAC maintenance to the customer. Because of the bigger companies greedy focus on unit sales, what they do is use high dollar advertising to pull unsuspecting customers into sales funnels and then create sales tactics to close high dollar sales deals.  Read More…
