Reasons for AC Replacement

For many homeowners, the thought of having to replace their AC system can be frightening. It is a major household expense, and even though it’s an investment because it adds value to your home, it’s still intimidating. Most air conditioning systems will last for up to 20 years if they are installed properly and maintained well. If your AC has reached the upper age limit and is starting to malfunction, getting a new one is probably a good idea. Some of the signs that AC replacement is on the horizon include intermittent blasts of warm air during cooling cycles, loud noises when it is in use and struggling to reach the programmed temperature on the thermostat.

How to Find a Reputable Installer

If you are at the point that AC replacement is necessary, it’s imperative that the system is installed correctly. When you are looking for a service provider, try not to rush and don’t be afraid to ask questions. A local choice will offer greater accessibility, and you can ask questions such as how long they’ve been in business, if they belong to any trade organizations and you may even get to speak to past customers to get their views on the service.

Don’t Forget About Maintenance

When you do find the right installation team and your new air conditioner is securely in your home or business, don’t forget to schedule regular maintenance visits. You won’t need one until the second summer, but keeping all the components clean will extend the life of your air conditioner and make it more efficient during times of heavy use.

Installing New AC Units in Oak Park and Chicago Since 1988

Coping with summer in Chicago requires a dependable and functioning central AC system. It’s even better if that cooling unit is also clean and energy efficient. After all, no one likes throwing money out the window. But it’s difficult for an AC unit to perform its best when its original installation was flawed. That’s where TDH Mechanical comes in.

Our customer-focused HVAC company has been serving the Chicago area since 1988. In that time, we’ve replaced hundreds of old units with new, more-efficient ones. Through this, we’ve helped your friends and neighbors shave hundreds off their utility bills. In other words, if you’re in the market for an AC replacement, we’re the company you can trust.

We get the job done right the first time, and it’s not done until you’re five-star satisfied. If you receive anything less than perfect service, we invite you to call us at (630) 200-5399. We’ll set things right.

Signs It’s Time for a New AC

We understand the urge to put off AC replacement. It’s expensive and inconvenient. And the idea of helping your current unit hobble along a little longer is tempting. But, eventually, it’ll have to be replaced. Below are a few signs that your current AC unit is nearing the end of its service life:

  • Skyrocketing Utility Bills: Older air conditioning systems are inefficient and often struggle to reach peak efficiency. As time goes on, it’ll take more and more money to cool your home. If you notice a sudden uptick in cost, a major system breakdown is often on the horizon.
  • Old Refrigerants: Older refrigerants damage the climate and have been replaced with newer, more eco-friendly ones. Due to this, though that old unit may still be working, replacing the refrigerant in case of a leak may no longer be a cost-effective option. In some cases, you might not be able to find a refill at all.
  • The Unit Never Shuts Off: Though it’s normal for your AC unit to run more during hot weather, failing air conditioners often struggle to reach target temperatures. This often leads to them constantly running, even during mild weather.
  • We're on a First-Name Basis: Even though we love our customers, those who make more than one repair call a season may be better off replacing their unit. Like dominoes, components tend to fail in sequence. This often ends with a catastrophic failure or a recommendation for total AC replacement.
  • Age: With proper maintenance, the average air conditioner can last over 15 years. But if yours is nearing that age, it’s often more economical to replace it. The U.S. Department of Energy estimates utility savings of between 20 and 40 percent after replacing an old unit.

How We Determine and Install the Proper AC Unit

Before replacing your AC system, we conduct a load calculation to determine the proper size of the replacement unit. We also take a look at your duct work and determine if any repairs are needed. When the number crunching ends, we present you with an AC installation quote.

In it, we price out everything from new condensers to updated drain lines and updated thermostats. We will also take time to discuss your budget and explore rebate, financing, and coupon options.

When done, we’ll have a proposal that ensures the system installed meets you and your family’s needs. Once all the paperwork is signed, our HVAC expert will take down your appointment preferences and get you scheduled. We look forward to adding you to our list of satisfied customers in the Chicago area.

Exploring the AC Replacement Process

Many homeowners aren’t sure what happens on AC installation day. To help ease your concerns, here is a breakdown of our process:

  1. We’ll call to remind you of the appointment and request that your pets be put away
  2. Our technician pulls on booties and lays down dropclothes to protect your floors
  3. Any items in the way will be moved to prevent any opportunity for damage
  4. The AC installer will measure everything a second time
  5. We break down your old equipment and load it up for recycling
  6. Our technician will bring in your new equipment and install it
  7. Refrigerant lines are attached to your main power source
  8. The power switch is flipped and the unit tested

After the initial test, our HVAC technician will do a few temperature checks to make sure everything is performing as expected. When diagnostics are complete, they’ll pick up their tools and remove the drop cloth. Then you, in renewed comfort, can flop back in the armchair.

What if I Need AC in a Newly Built Home?

First, let’s start with a congratulations!

We hope your new home is everything you dreamed of. The process for installing a new AC system in the Chicago is similar to replacing a system. The same calculations are made and the same steps taken to prevent safety issues. The main difference comes during the set-up process.
