During an Illinois summer heatwave, the hot air gets trapped inside your home, and unless you have an effective air conditioning system, it isn’t leaving. Even at night with the windows open, the heat can be unbearable. If there is no breeze to offer any relief, you’ll be doing more sweating than sleeping. That is why it is so important to keep your system running efficiently all summer long.

Typical AC Problems

General wear and tear kind of damage can happen to any system, but it’s important to notice the signs before they end up shutting your system down when you are depending on it. Some of the signs that may precede an AC breakdown include leaking refrigerant around the evaporator coil, frozen coils, lukewarm air coming from the vents when it should be cold, knocking or banging noises coming from the main unit and jumps in your energy bill for no apparent reason. If you see any of these signs, don’t wait long before you call for help.

Why You May Need It Replaced

Once your air conditioning system gets up to around the 15-year mark, things will start going wrong just because the system is older and weaker than when it was younger. After so many years, there are also newer and more energy efficient models available that can save you quite a lot of money on your monthly cooling bills. If your system is older and you notice the repair bills are getting into the hundreds no matter what you do, replacing your system with a new one may be the best option. A consultation with your service provider should give you all the answers you need.

Why Work with Professionals?

To ensure your AC system has the best possible care, whether it is with repairs, maintenance or replacements, insist on using a professional, reputable company for all services. There are so many ways to cause damage to yourself and your home when repairing and installing air conditioning systems, it isn’t worth the risk.

Things to Look For in an AC Contractor

When it comes time to pick a good HVAC company in Lincolnwood or Chicago, there are a number of things to look out for. The signs of a skilled provider include:

  1. Knowledge and Experience: How long has the company been in business? Are their HVAC technicians experienced professionals? Our company has been helping Oak Park keep and stay cool since we opened our doors in 1988.
  2. Good Reputation: What do people on Facebook, Google, and BBB have to say about the company? How do they handle problems that arise? If their reviews show a bad reputation when it comes to AC repair in Chicago, go with someone else.
  3. Stated Warranties: Do they guarantee your satisfaction? What kind of warranty comes with their AC repair and replacement services? At TDH Mechanical, Inc., we always stand behind our work and go out of our way to satisfy our clients.
  4. Active Licenses: Are they licensed or certified with the state? We are! Though you may save up front with a local handyman, insurance may not cover issues related to the system. Many handyman also don’t fully understand the intricacies of duct load and air conditioning requirements.
As you might have guessed, our local heating and AC company fits all of these criteria. This is why so many people in Illinois trust us to handle their comfort problems.

Other Air Conditioning Options

Not every HVAC situation can be solved by a traditional central air conditioning system. There are niche circumstances where we’ll recommend another cooling solution. These alternatives include:

  • Heat Pump: These versatile pieces of equipment used to be only suited for temperate climates. However, with today’s technology they are a good choice even for the coldest areas. This is because of their ability to efficiently provide both heating and cooling. Thanks to their efficient inverters, newer heat pumps can keep your home comfortable all-year long.
  • Ductless Mini-Splits: If your home is too old for ductwork—or you need a way to better heat and cool your new addition—a mini-split can be a great option. When it comes to heating and air conditioning your home in Chicago, they provide a level of flexibility traditional units can’t match.
  • Swamp Coolers: If you live in an arid area, you might want to consider a swamp cooler. These AC alternatives, often referred to as evaporative coolers, cool your home in a similar manner to how sweat cools your body. For more information on swamp coolers in Chicago, give us a call at (630) 200-5399.

Frequently Asked AC Questions

How Much Will AC Service Cost Me?

A lot of clients ask us this question. They want to know how much a new system or repair will cost before we go inside. Because of the numerous factors involved in AC service and replacement, we can’t provide estimates until we are on site and able to diagnose the problem. Many issues present similarly. This can make it difficult to uncover the source of your air conditioner problem over the phone. And, the last thing we want to do is give you the wrong price.

Is Replacing or Repairing My AC the Better Option?

Major AC repairs, like leaks and condenser replacement, can run into four digits. Costs like these can make it a difficult to decide if it's time to bite the bullet and replace the unit, or if the investment in what you have is worth it. The answer to this question depends on the age and condition of your unit. If your unit is over 10 years old, or relies on old refrigerants, replacing it is often the better option. If new AC installation in Chicago is in your future, we invite you to reach out to us at TDH Mechanical .

What Do I Do If My AC Quits?

You get home from work, and your house's a hotbox. First, don't panic. It's not always because of a major component failure. Start by checking that your unit hasn’t tripped the breaker and your thermostat is set to cool. If it’s been over a month since your last filter replacement, see how dirty the membrane is. Finally, if your unit is dirty, try gently brushing it off. If none of these things help get your AC working, give us a call at (630) 200-5399.

Should I Set My Thermostat to Auto Or On?

For homeowners who want to keep their cooling costs low, we suggest setting the thermostat to auto. This means it only turns on when it's needed to maintain the selected temperature. If you want things consistent, and don't mind spending nore to cool your home, you can set it to on. Just remember to turn it off before your home becomes an ice box!

What Brands Do You Service?

You might love your current AC unit and want someone to fix it. Rest easy knowing our AC experts can handle it. Our Chicago-area HVAC company services all major AC brands including Trane, Goodman, Amana, Carrier, Bryant, Rheem, and American Standard.

Should I Be Worried If My AC Unit Is Leaking Condensation

One of your air conditioner's major functions is to remove humidity from the air. So, a little bit of condensation is to be expected. If you notice an unusual amount of water, however, something may be wrong. This could include a lack of refrigeration, a dirty filter, or a problem with initial installation.

How Can I Reduce Energy Costs?

With your typical HVAC system counting for roughly half of your energy consumption, you should always be looking for ways to cut down on energy consumption. If your electric or heating bills are giving you the blues, consider:
  • Upgrading Your AC System: Though this may seem like a counterintuitive way to save money, this move often pays for itself. Newer units not only cost less to run but also tend to be both more environmentally friendly.
  • Opt for an Energy Efficient Cooling System: Going for an ENERGY STAR unit can save you $3 to $4 per square foot according to data from the US Department of Energy. Rebates are often available to make new AC installation in Chicago more affordable.
  • Landscape Around Your Unit: Make sure that the area around your air conditioner is clear of brush and debris. Plants should be kept two to three feet away from the appliance. You should also turn off the unit every so often to wash it. These obstacles can make it more difficult for your unit to perform at an acceptable level.
  • Keep Your Curtains Closed: To limit summer cooling costs in Chicago, make sure to keep your curtains and windows closed. The less heat introduced into the system, the more efficiently your air conditioner can do its job.
