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.

Only Professional HVAC Services

Sun State HVAC is your go-to expert for AC Repair, Heating Services, Air Balancing, and Refrigeration. Our team is composed of seasoned professionals committed to excellence in every facet of HVAC repair and maintenance.

Locating skilled AC Repair Technicians can be challenging, and those proficient in this domain rightly command respectable compensation. Yet, a noticeable trend has emerged where many firms have diverted their focus from HVAC to plumbing, causing a scramble among customers seeking dependable HVAC expertise.

This trend includes companies originally focused on HVAC repairs pivoting to market themselves primarily as plumbing services, often emphasizing “Plumbing and Air Conditioning,” a switch that can dilute their commitment to HVAC excellence.

At Sun State HVAC, we champion the value of specialization: just as auto mechanics specialize in vehicles, and doctors in health, we believe HVAC technicians should focus on heating, ventilation, and air conditioning. This dedication ensures our team is not only highly trained but also supremely capable of addressing any HVAC challenge with unmatched precision and professionalism.

Choose Sun State HVAC for a difference you can feel and trust. Our dedication to professionalism and quality stands out distinctly. Reach out to us today and see why we are renowned for delivering top-tier HVAC services underpinned by integrity, where “Honesty Rules!”
