Signs That It’s Time for a New AC in Carol Stream and Bloomingdale

We understand the urge to put off AC replacement. It’s expensive and inconvenient. It's also not something most people in Carol Stream 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 Bloomingdale 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 401A and R-22) damage the climate and have been replaced with newer, more eco-friendly ones. Due to this, though that old AC in Carol Stream 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 Bloomingdale 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 Bloomingdale or Carol Stream.
  • 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 (630) 283-7981 right away! Tackling the issue head on can mean you end up with a bill for AC repair in Carol Stream 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 Carol Stream could have been prevented with a little bit of forethought. That's why Gray's 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 Carol Stream. 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.

When done, you'll have a proposal that ensures the installed air conditioning system meets you and your family’s needs. After 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 Carol Stream area.

What if I Need AC Installed in a Newly Built Home?

First, let’s start with a congratulations! We hope your new home is everything you dreamed of. Our local HVAC company is proud to work with a number of home builders and remodelers in the Carol Stream area. So, we're often called upon to design and install new-build systems.

The process for installing a new AC system in Carol Stream is similar to replacing one. The same calculations are made and the same steps taken to prevent safety issues. The main difference comes during the set-up process. When a clean installation happens, we’ll also be responsible for designing properly functioning ductwork. Because it’s a new build, there’s open access and no old air conditioner requiring disposal. This process is the same if you live in a home in DuPage County without an existing cooling system.

Frequently Asked Questions - AC Replacement

It typically does! Replacing an old air conditioner in Glendale Heights 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 Carol Stream. 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 Bloomingdale 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 Carol Stream 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 Glendale Heights or Carol Stream. 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 Glendale Heights, 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 Glendale Heights to the HVAC experts at Gray's Heating & Cooling.

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 Bloomingdale 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:

There's no universal answer to this question. Every home in Carol Stream 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 Carol Stream 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 Carol Stream's AC service expertsGray's.

A simple AC replacement in Carol Stream 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 Carol Stream can enjoy the benefits of central air. But, before you call your local building contractor, give (630) 283-7981 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.

World-Class Furnace and Heat Pump Installation
My experience with Gray's was world class. From the initial estimate walk through in my home, to the installation of my new heat pump and furnace, the experience was pleasant the whole way through. The entire process with Gray's was efficient and effective, just like our new HVAC system. They've found the perfect combination of new school technology and old school relationship building. I feel like I'm in the right hands going forward!
Drew Doster
Friendly Late-Night HVAC Service
Gray's, thank you for sending Anthony to us. It was a late night emergency call. He was very friendly, courteous, knowledgeable and extremely professional. We will definitely keep your company in mind should we need any additional service. Thank you!
Hector R O
Respectful, Informative, and Fast AC Repair
We had Gray's come out to see why our AC unit wasn’t cooling correctly. They were able to come out right away, then figured out we had a small leak. We were given options by the tech that made me feel like I wasn’t being forced into a decision I didn’t want to make like I’ve felt from other companies. I wasn’t being talked into buying a whole new system, which was very important to me. Kirby was able to fix everything up that day and we had cold AC in under 3 hours. The office staff were easy to deal with. I also spoke to the owner, Dan, when he followed up with me and he was super friendly and professional.

Efficient AC Repair and Helpful Maintenance Tips
I recently had Sergio and Eric come over to update our AC unit for the summer, and I couldn't be more pleased with their service. From the moment they arrived, their professionalism was evident. They thoroughly inspected our unit and quickly diagnosed the issue causing it to shut off unexpectedly. Not only did they fix the problem efficiently, but they also provided us with excellent recommendations to prevent future issues. Their expertise and friendly demeanor made the entire experience seamless. I highly recommend Sergio and Eric for anyone in need of AC maintenance or repairs.
Marcus Howard
Effective Heat Exchanger Cleaning Fixed Furnace Fast in Sub-Zero Weather
We were in desperate need of help. Our furnace had stopped working and the sub-freezing temps were expected to drop to zero. Panic was setting in. But, Gray's was able to send their skilled technician, Sergio, who arrived almost two hours ahead of schedule. Sergio, diligently and expertly examined the furnace. Eventually, he diagnosed that a very dirty heat exchanger was causing poor airflow causing the system to shut down. He then spent a considerable amount of time in a very cramped space cleaning the suspect part. Eventually, he emerged, dirt smudged on his face with a bag filled with dirt. The system restarted and we are not in danger of suffering from hypothermia.
