The Importance of Annual AC Tune-Ups

You likely wouldn’t drive your car for years without routine oil changes and maintenance. It’s just as important to get yearly tune-ups for your home AC system. Our Whole House Comfort Plan provides an annual 20-point tune-up, saving you 15% off regular repair rates if issues later occur.

Benefits include:

Improved Efficiency: A well-maintained unit runs more efficiently, keeping electricity bills lower. Studies show yearly tune-ups can reduce costs by as much as 40%.

Extended Equipment Life: Routine maintenance identifies minor problems before they become major repairs, adding 5-10 years to the system’s functional lifespan.

Increased Capacity: Dirty components reduce airflow and functionality. Cleaning improves cooling capacity. Tune-ups ensure your AC works its best when you need it most.

Fewer Repairs: Catching small issues early on avoids system failures in peak summer. 60% of AC repairs are preventable through regular maintenance.

Better Air Quality: Changing filters and cleaning components improves indoor air quality for a healthier home. 

Peace of Mind: Knowing your AC is regularly assessed for proper and efficient operation provides comfort and confidence heading into warm weather. 

By investing just a little now in preventative maintenance, you save substantially over time in avoided repairs and replacements.

Common AC Problems

Central Georgia’s hot, humid climate puts home AC systems to the test. While robust units can last over 15 years with proper maintenance, repairs are sometimes unavoidable. Here are some of the most common issues our experts address:

Low Refrigerant: Over time, refrigerant can slowly leak out, reducing cooling ability. We can test levels and top off the R-410A refrigerant 

Drainage Problems: Clogged condensate drains prevent humidity removal, causing AC coils to freeze with reduced airflow. We clear buildup for proper drainage.

Dirty Filters & Coils: Dust and debris lower efficiency and use more energy. Cleaning improves capacity. Checking filters should be part of regular maintenance.

Electrical Issues: Faulty capacitors, contactors, fuses or wiring connections disrupt the AC system. Our techs are adept troubleshooters.

Noisy Operation: Unusual noises like grinding, squeaking or banging indicate mechanical problems. We identify the origin and recommend fixes.

Compressor Failure: At the heart of the AC system, compressor breakdown is serious. Depending on the system’s age, we offer replacement or new AC installation options.

With deep expertise in central and ductless AC systems, our team has seen it all. We’ll accurately diagnose even complex repair issues and clearly explain recommended solutions. You can feel at ease knowing the job will be done right.

Frequently Asked Questions

What are the common signs that indicate my commercial HVAC system requires professional attention?

Several signs can indicate issues with your commercial HVAC system. These include:

  • Unusual Noises – Strange sounds like banging, clanking, or hissing could indicate mechanical problems.
  • Inconsistent Temperature – If certain areas of your commercial space are warmer or cooler than others, it may signify a problem with the distribution of air.
  • Increased Energy Bills – A sudden spike in energy costs without changes in usage patterns could indicate inefficiency or a malfunctioning component.
  • Poor Air Quality – Dusty or stale air, unpleasant odors, or increased allergies among occupants may suggest problems with air filtration or circulation.

If you notice any of these signs, it’s advisable to schedule a professional inspection to identify and address potential issues before they escalate.

Are emergency commercial AC repair services available, and how quickly can a technician be on-site?

Yes, Air Conditioning Services understands the urgency of commercial HVAC issues, especially during extreme weather conditions. We offer 24/7 emergency commercial AC repair services to ensure minimal disruption to your business operations. When you contact us for emergency repairs, our team prioritizes your request, and a certified technician will be dispatched promptly to assess and address the issue. Our goal is to restore your HVAC system to optimal functionality as quickly as possible, helping you avoid downtime and maintain a comfortable work environment.

How often should I schedule commercial AC maintenance, and how does it differ from repairs?

Regular commercial AC maintenance is crucial for preventing unexpected breakdowns and extending the lifespan of your HVAC system. We recommend scheduling maintenance at least twice a year, ideally before the start of the cooling and heating seasons. Maintenance involves tasks such as cleaning coils, checking refrigerant levels, inspecting ductwork, and ensuring all components are in optimal condition.

On the other hand, commercial AC repairs are necessary when your system malfunctions or exhibits issues. The frequency of repairs depends on factors such as the age of the system, usage patterns, and how well it’s maintained. If you notice unusual sounds, uneven cooling, or increased energy bills, it’s advisable to schedule a professional inspection for potential repairs.

How can I optimize energy efficiency in my commercial HVAC system to reduce operating costs? 

Optimizing energy efficiency in your commercial HVAC system is crucial for cost savings. Here are some tips:

  • Regular Maintenance – Schedule routine maintenance to ensure all components are clean and functioning optimally.
  • Programmable Thermostats – Install programmable thermostats to regulate temperatures based on occupancy and usage patterns.
  • Seal Leaks – Ensure that your building is well-insulated and free of drafts to prevent energy wastage.
  • Upgrade to Energy-Efficient Systems – Consider upgrading to newer, energy-efficient HVAC systems that comply with industry standards.
  • Employee Training – Educate staff on energy-saving practices, such as closing doors and windows when the HVAC system is running.

Implementing these measures not only reduces operating costs but also contributes to a greener, more sustainable business environment.

How can I tell if my commercial HVAC system needs immediate repair or replacement?

Identifying whether your commercial HVAC system needs repair or replacement depends on several factors. If your system is relatively new and the issues are minor, repairs might be the most cost-effective solution. However, if your system is outdated, requires frequent repairs, and struggles to meet your business’s heating and cooling demands, it may be more economical to consider a replacement.

Signs that immediate repair is necessary include strange noises, inconsistent temperatures, increased energy bills, and visible leaks. Our certified technicians at Air Conditioning Services conduct thorough assessments to determine the most suitable course of action for your specific situation.
