Signs That It’s Time for a New AC in Lisle and Downers Grove

We understand the urge to put off AC replacement. It’s expensive and inconvenient. It's also not something most people in Lisle bother to budget for. The idea of helping your air conditioner 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 in Downers Grove 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 on the horizon.
  • Old Refrigerants: Older refrigerants (like R-22) damage the climate and have been replaced with newer, more eco-friendly ones. Due to this, though that old AC in Lisle 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. If you notice your air conditioner in Downers Grove staying on longer than usual, it's a good sign that AC maintenance or replacement is necessary.
  • We're on a First-Name Basis: Even though we love our customers, those who make more than one AC repair call a season may be better off replacing their central air system. Like dominoes, components tend to fail in sequence. This often ends with a catastrophic failure or a recommendation for a replacement air conditioner. Since quotes are free, there's no reason not to call for a quote on a new AC unit in Downers Grove or Lisle .
  • 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.

If you notice any of these symptoms, place a call to (708) 879-3531 right away! Tackling the issue head on can mean you end up with a bill for AC repair in Lisle and can put off getting a new unit a little longer. Waiting, meanwhile, is likely to lead to snowballing and worse issues down the road.

How We Determine and Install the Proper AC Unit

One of the biggest causes of wasteful air conditioners is improper sizing and installation. A lot of AC repair calls in Lisle could have been prevented with a little bit of forethought. That's why CPR takes time to properly determine your home's specific needs. This includes determining the correct size of your new air conditioner. Math is involved. We also will recommend things like air handlers, air filtration systems, ductwork repairs, and zoning up front to save you money on overall installation and operating costs.

After we're done, we'll present you with a quote on AC replacement in Lisle . In it, we list the prices of everything from new condensers to updated drain lines and new thermostats. We will also take time to discuss your budget and explore rebate, financing, and promotional options.

Frequently Asked Questions - AC Replacement

It typically does! Replacing an old air conditioner in Naperville can raise your home's value by as much as 10 percent. This value depends on the efficiency and features of the new unit. In some markets, you can't even sell a home that doesn't have a cooling system installed. So, even if you plan to sell in the near future, you might want to consider footing the bill for an updated air conditioner.

A lot of homeowners think that bigger is better when it comes to air conditioning in Lisle . But that's not true. While an oversized air conditioner will cool your house more quickly, it will use more electricity to do so. It'll also struggle to remove the humidity from the air. Though you might not like your AC unit in Downers Grove running for hours on end, long cycles are better for your wallet and home than short ones.

Air conditioners have both interior and exterior components. Some homeowners in Lisle think replacing just one of those is a great way to reduce AC repair and installation costs. It's not. Having mismatched components can lead to frequent repairs, higher energy bills, and reduced efficiency. Though the price tag might look scary, doing both sides of your cooling system will ultimately save you money.

We suggest you get multiple quotes on AC replacement in Naperville or Lisle . This is the best way to ensure you get a fair deal. Do note, however, that you need to be comparing apples to apples. Does the other HVAC company offer a warranty as good as ours? Is the unit from the same brand or as good? How long have they been in business? You will need to keep these things in mind as you make your decision. We invite you to check out our financing page and special offers page to see what deals we're currently offering.

While you might be tempted to repair or replace your own air conditioner in Naperville, you shouldn't. There's a lot that goes into sizing, installing, and testing an air conditioner. Beneath that shell, there are a number of electronic and chemical components. Tinkering with these can lead to injuries and even death. So, unless you have the proper certifications, we suggest leaving AC replacement in Naperville to the HVAC experts at CPR Mechanical.

As mentioned earlier, once your air conditioner gets past 10 or 15 years old, it's time to start budgeting for a new one. Like with a lot of other products, HVAC equipment pricing is cyclical. For better AC deals, start shopping early before summer hits its stride. When winter temperatures start breaking toward spring, a lot of local HVAC contractors may be slower and scheduling is a lot easier. It's also a period where many financing deals are offered. For Illinois, this means anywhere from February to April.

Shopping for a pair of shoes online is one thing. Trying to purchase a new AC unit in Downers Grove is another. You should always get a quote from a licensed HVAC contractor. They have the skills needed to properly measure your home to calculate the equipment that is optimal for your needs. There are a few things, however, we recommend to everyone:

  • Make sure the contractor installs AC equipment from a well-regarded brand
  • If you're not selling your home, invest in something more energy efficient
  • Ask about what their AC replacement includes warranty wise

There's no universal answer to this question. Every home in Lisle is different. Things like local codes, square footage, building materials, drafts, wall direction, and even homeowner association rules can affect selection of your new AC's site. For that reason, there's no secret formula to picking the right spot. We recommend looking for:

  • Shady Areas: In Lisle it's helpful to try and keep air conditioners cool as well. So, if possible, we typically place it on the north or east side of your home. If that isn't an option, it can also be placed under a leafy tree.
  • Somewhere Away from Pets: Dogs and other animals like to pee on air conditioners and chew on connections. The refrigerants and metals can be harmful to your pets. Over time, urine can eat through the fan blades. If you don't have a sheltered area, we recommend surrounding it with a fence or shrubs to limit animal access.
  • Places with Grass or Mulch: Most air conditioners are placed on concrete or PVC slabs. These radiate heat back up toward the unit. The added heat can make the unit work harder to cool your home. If there's no grass or mulch around the best location, we might recommend adding some.

At the end of the day, however, the best way to find the perfect spot is to reach out to Lisle 's AC service experts—CPR.

A simple AC replacement in Lisle typically takes between four and six hours. This estimate may increase if the installation team has to flush the line or add brackets. If you want a more accurate estimate of how long it'll take to put in your new AC unit, just ask our technician. They will be happy to walk you through the process.

If you're willing to invest in ductwork and design adjustments, any home in Lisle can enjoy the benefits of central air. But, before you call your local building contractor, give (708) 879-3531 a jingle first. We'll not only walk you through the installation process, but we'll help you explore alternative cooling options as well. Things like ductless mini-splits, whole house fans, evaporative coolers, and heat pumps may be able to give you many of the same benefits at a lower upfront cost.
