Comprehensive Air Conditioning Maintenance Services

Our air conditioning maintenance services are designed to keep your system running efficiently and effectively. During a maintenance visit, our technicians will:

  • Inspect and clean the condenser coils to ensure proper heat transfer and prevent overheating
  • Check and calibrate the thermostat for accurate temperature control
  • Lubricate moving parts to reduce friction and wear
  • Tighten electrical connections to prevent safety hazards and improve system reliability
  • Test the system’s overall performance to identify any potential issues before they become major problems

By regularly maintaining your air conditioning system, you can enjoy a range of benefits, including improved energy efficiency, reduced utility bills, and extended equipment lifespan. In fact, according to the U.S. Department of Energy, proper maintenance can help your air conditioner maintain up to 95% of its original efficiency, saving you money on energy costs and reducing your carbon footprint.

Our family-oriented business is large enough to service all makes and models of equipment, yet small enough to provide personalized attention to each and every customer.

Whether you need routine maintenance, repairs, or a new system installation, you can trust Guardian Heating & Cooling to get the job done right the first time.

The Importance of Regular Air Conditioning Maintenance

Just like your car requires regular oil changes and tune-ups to run smoothly, your air conditioning system needs regular maintenance to function at its best. Neglecting maintenance can lead to a range of problems, including reduced cooling capacity, higher energy bills, and even complete system failure. By investing in regular maintenance, you can avoid costly repairs and extend the life of your equipment, saving you money in the long run.

In addition to the financial benefits, regular air conditioning maintenance can also improve your home’s indoor air quality. Over time, dust, dirt, and other contaminants can accumulate in your system’s components, reducing airflow and potentially circulating harmful particles throughout your home. During a maintenance visit, our technicians will thoroughly clean your system, removing any build-up and ensuring that your home’s air is clean and healthy.

Guardian was a lifesaver - They came out on short notice for a quote and were able to come the next morning to install our new AC. Jonathan was a fantastic rep as well, very informative and helpful. Highly recommend.

I've used this company twice already and both times have been great! Last night, our A/C was not cooling our 3,000 sq ft house and with a toddler in the mix, we needed to get this fixed fast! With that being said, I called the next morning and they were able to be accomodating to my request of coming over to fix it. Less than an hour later, they called to mentioned they'll be over that day! Lisandro came over and figured out what the issue was a knocked it out in less than hour. Ironically enough, I had an A/C tune up scheduled for the follow day. So he was able to take care of that as well. Needless to say, with the temps in the 90's this week, we back to the A/C running on all cylinders. I highly recommend this business!

Guardian Heating and Cooling has been my heating and air conditioning contractor ever since I moved into my Chicago home 25 years ago. I have replaced/upgraded my furnace and air conditioner over the years, and, at the same time, followed regular seasonal maintenance on my units. All systems are good and running well, but my concern for my ever-increasing gas bills prompted a request to have Guardian come to my home and consult, evaluate, and advise me on possibly improving the efficiency of my home heating and cooling systems. Jasper and Jonathan arrived promptly, introduced themselves, and first, asked me about my concerns. After a thorough walk-through and accompanying explanations of possibilities, they advised me on how to improve the comfort levels, both heating and air conditioning. They explained everything clearly and completely, and there was never any pressure to change and/or update and then spend, spend, spend. They gave me honest advice which I understood and appreciated, and which ultimately did improve the comfort levels in my home for both heating and air conditioning. Jasper and Jonathan, thank you again. I am one happy Guardian Heating and Cooling customer!
