Air Conditioning


As you know, living here in the Tinley Park, IL, and surrounding South Suburbs area, it gets hot and muggy during the summer months. For most of us, living without an air conditioner (AC) in our homes seems unthinkable. For the highest degree of comfort throughout the high temperatures, you want to be sure your cooling system is operating at peak performance.

Our professionals are highly trained in cooling systems, no matter if you are looking for a repair, a new air conditioner, or maintenance.

We are both US Environmental Protection Agency (EPA) and North American Technician Excellence (NATE) certified as well as factory trained, meaning we have the knowledge we need to meet your needs. And with as many years as we have been in the heating, ventilation, and air conditioning (HVAC) industry, you can believe we have the experience that goes hand in hand with our knowledge.

When You Need Air Conditioning Repairs

The majority of air conditioning systems require a repair at least once in their lifetimes, even with the most diligent of regular maintenance. Sometimes, due to normal wear and tear, parts simply need replacing. When this situation happens to your air conditioner, you want to be sure you have the best professionals for the job.

And if you require emergency service, once again, you can rely on us. We are always here for you. In fact, we feel so strongly about being here for you in emergencies, we will have one of our trusted team members answer the phone.

You can also trust our comfort experts will install the correct part effectively when you need a repair. At Doornbos Heating and Air Conditioning, we guarantee our work. Our team will fix it right the first time, getting your cooling system back on track so you can enjoy the comfort of your home once again.

When You Need a New Air Conditioner

If you are in the market for a new air conditioner, whether you are moving to a new Tinley Park and surrounding South Suburbs home or if your current system needs replacing, our knowledgeable professionals will help you design a new system perfectly suited to your needs. We work hard to calculate the appropriate size for your cooling system to precisely cool your home when and where you need it.

Our professionals recognize that to get the highest-efficiency systems requires using the best equipment and materials. That is why we choose to work with the top HVAC manufacturers in the industry. From our experience, we know installing high-efficiency air conditioners gives the most reliable cooling and the biggest cost savings. The higher the efficiency, the less energy being used, which translates to money savings for you.

And when we are working in your home, we will treat it with the respect it deserves. Our professionals will leave the working site in the same condition, or better, it was in when we arrived. We always speak to and treat you with respect.

When You Need Air Conditioning Maintenance

When you care for your air conditioner on a regular basis, you will reap the benefits. Having one of our HVAC experts inspect and clean your air conditioning system at least once a year, typically prior to using it at the start of the season, keeps your system operating at its highest efficiency and saves you energy costs.

By also having consistent maintenance, we can alert you of any needed repairs. This prevents those unexpected and costly emergency situations in most cases.

Even when you plan on scheduling HVAC maintenance for your system, many times it falls through the cracks. We are all so busy these days. One of our strategies to help you with this is our maintenance agreement plans.

When you participate with one of our plans, we will remind you when it is time for your appointment. We will then send out one of our qualified and highly trained professionals to fully inspect and take care of your system. Knowing this is such an important job, any of our professionals performing this job must have a minimum of six years experience. Not just anyone can do this job. You can always trust we will take the greatest care of you and your home.

With one of our maintenance plans, you will also receive additional perks like preferred scheduling for seasonal maintenance appointments, discounts on services, and priority service. There are many advantages to leaving your heating and air conditioning maintenance in our hands. Call us for more details.
