Evaporative Cooler Service

Because you live in an arid area like Carol Stream, you get access to another eco-friendly cooling option. Operating off of the same principles as perspiration, evaporative or 'swamp' coolers use a moist pad to bring down the temperature inside your home. Typically perched on roofs, they can be difficult for your typical homeowner to maintain. Luckily, whether you need to replace or repair your swamp cooler, Gray's is here for you. Call (630) 283-7981 to schedule swamp cooler service in Bloomingdale or Carol Stream.

Air Handler Service

If you're fortunate enough to live in Carol Stream, you can probably get by without a dedicated heating system. But, without a furnace or blower, the cool air your AC unit generates would just fall right inside your home. Air handlers are added to existing cooling systems to allow for air distribution. And, at Gray's, we know how to install, repair, and maintain them.

Service Your Air Handler

Whole House Fans

When spring and fall hits, Carol Stream can be pretty mild. In those times, turning on your AC unit is just overkill. That's where whole house fans come in. Typically installed at the peak of a home, these high-powered fans pull air from the outside and push it through your home. It can help to think of them as hidden ceiling fans. To get a quote on installing a whole house fan in Glendale heights or Bloomingdale, give (630) 283-7981 a call.

Things to Look for in an AC Contractor

When it comes time to pick a good HVAC company in Glendale heights or Carol Stream, 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 Bloomingdale get and stay cool since we opened our doors in 2019.
  2. Good Reputation: What do people on Facebook, BBB, and Google 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 Carol Stream, 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 Gray's Heating & Cooling, we always stand behind our work and go out of our way to satisfy our clients.
  4. Active Licenses: Are they licensed or certified to work in Illinois? We are! Though you may save up front with a local handyman, insurance may not cover issues related to the system. Many handymen 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 DuPage County trust us to handle their comfort problems.

Other Air Conditioning Options

In Carol Stream, not every situation can be solved by a traditional central air conditioning system. That's where alternative cooling solutions come into play, catering to specific niche circumstances. Let's take a look at some of these cooling options

  • Heat Pump: Gone are the days when heat pumps were only suitable for temperate climates. Thanks to modern technology, heat pumps are now a fantastic choice even in colder areas. The magic lies in their efficient ability to provide both heating and cooling. With advanced inverters, newer heat pumps keep your home comfortable regardless of the weather outside.
  • Ductless Mini-Splits: If your home lacks ductwork or you want a more flexible way to regulate the temperature in a new addition, ductless mini-splits are an excellent option. Offering both heating and air conditioning capabilities, these systems provide a level of adaptability that traditional units simply can't match.
  • Swamp Coolers: For those residing in arid areas, swamp coolers can be a worthy consideration. Also known as evaporative coolers, these AC alternatives work on the principle of evaporative cooling, much like how sweating cools our bodies. If you want more information on swamp coolers in Carol Stream, don't hesitate to reach out to us at (630) 283-7981.

At Gray's Heating & Cooling, we're well-versed in all these cooling solutions and can guide you towards the best option for your specific needs. If you're looking to explore alternative cooling methods for your home, simply schedule a service or get in touch with our team. With our expertise and dedication, we'll ensure you find the perfect cooling solution to keep your home comfortable all year round.

Frequently Asked AC Questions

How much will AC service in Carol Stream cost me?

A lot of customers in Carol Stream ask for pricing over the phone. They think of AC service like a commodity—something with a pre-determined price. But we can’t provide accurate diagnoses remotely. There are a number of factors involved in Bloomingdale AC service and replacement. And, until we’re on-site, we can’t take all of them into account. We want to provide a firm and accurate price. Rest assured, our local HVAC contractors won’t start work until you agree to our plan and charges. Give us a call at (630) 283-7981 to get started.

Major AC repairs in Carol Stream, like condenser replacements, can easily run into the thousands. Prices like that can make it hard to decide if a new AC installation or a repair is the better option. The right answer depends on a number of factors including the age of your unit. If your air conditioner is over ten years old, we usually suggest replacing it. As time goes on, it’s only going to get less efficient. Putting off the replacement, in those cases, almost always costs you more in the long run. For newer AC units in Carol Stream, repairing them is typically the better, more economical route.

Your home feels like a sauna because your AC is out. Don't suffer, worried it's going to cost an arm and a leg for AC service in Bloomingdale or Glendale heights. It may be something simple. First, verify that your breaker hasn’t tripped, and your thermostat is set to cool. If you haven’t swapped filters in a while, it might be time to take a look. Lastly, if debris clings to your outdoor unit, hose it off. If none of these work, give our Carol Stream HVAC service company a jingle at (630) 283-7981.

For people in Carol Stream who want to keep utility bills low, set the thermostat to ‘Auto’. This means your air conditioner's fan only turns on when the thermostat reaches a certain temperature. If you prefer consistency—and don’t mind spending more to climatize your space—On is ideal.

The AC service experts at Gray's are qualified to fix any brand or model of air conditioner. This includes all major brands such as Amana, Daikin, Comfortmaker, Mitsubishi, Carrier, Bryant, Rheem, American Standard, and Trane. Even if your AC unit in Carol Stream is from some obscure manufacturer, we’re equipped to diagnose and repair it. Reach out to us at (630) 283-7981 to schedule an appointment.

Removing humidity is one of your air conditioner’s major functions. So, you shouldn’t be surprised to see a little condensation on your ductwork. If you find huge puddles or notice a constant drip something’s wrong. Typical causes of leaks include a lack of refrigerant, initial AC installation issues, dirty filters, and clogged condensate lines.

Reducing HVAC energy consumption is a great way to save on energy bills. Consider upgrading your AC system to a newer, more efficient unit, as it often pays for itself over time. Opting for ENERGY STAR-rated units can also lead to substantial savings and potential rebates. Keep the area around your AC unit clear of debris and vegetation, and keep your curtains and windows closed during the summer to limit heat entering your home, allowing your air conditioner to work more efficiently.

I’ve had the pleasure of working with Gray's both personally and professionally. They’ve handled my regular furnace and AC maintenance for many years, always to my satisfaction.

Jacqulin Goodlove-Schroeder
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.
Jonelle Salinas
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.
