Signs You Might Need a New Heater

A lot of homeowners cross their fingers in hopes that their heater or heat pump can be repaired. Even a few hundred dollars for a repair is much easier to come up with than thousands for a total system replacement. But wishes don’t always come true. There comes a time in every HVAC system’s life when repairing it is no longer feasible or economical. This can be due to low parts availability, rust, or age. If you notice any of the following symptoms of a heater on its last leg, it might be time to start saving for a new heater:

  • Old age: Like cars, all heating systems degrade with time. While regular maintenance can extend the lifespan of your unit, it can’t do so indefinitely. If your unit was made more than 10-15 years ago, most HVAC experts will recommend replacing it.
  • Frequent Repairs: Are you now on a first-name basis with our HVAC technician? Have you called them out more than once or twice this season? Well, it might be a sign that a major repair (and likely replacement) is incoming. In many cases, it’s better to proactively replace the unit during a slower time of year than to wait for that last domino to fall. In more temperate times, rebates and special heating system discounts are often available.
  • High Energy Bills: As your heater ages, it may use more energy to achieve the same level of comfort. Over time, you’ll see this reflected in your monthly utility bills.

Fortunately, no matter the size or scope of the problem, Gray's can handle your heater repair or replacement. For prompt heating service in Carol Stream, Bloomingdale, or Glendale heights, give (630) 283-7981 a jingle.

How to Ensure You Get the Best Heater for Your Home

After you’ve decided to replace your old heating system, it’s time to consider what you want to replace it with. When estimating the total cost of installing a new system, you’ll need to take the following into account:

  • Energy Efficiency: Everyone knows using less energy and saving money is smart. Do you mind paying more upfront for a unit that saves you money over the long term? For people looking to save, we suggest installing a unit with an AFUE of above 90. The higher the energy efficiency, the less sting you'll experience in your heating bills.
  • Sizing: How large or how small is your home? This can have a huge impact on the cost of a new heater as well as how efficiently it runs. And, honestly, that makes sense. Heating a home with two or three stories takes a lot more power than a ranch-style house. While some homeowners think bigger is better, that’s not the case when it comes to HVAC. A unit that’s oversized often short cycles, which leads to loss of efficiency and puts more wear on parts. It’s sort of the same effect as highway versus city driving.
  • Fuel Source: The type of fuel your home uses can also impact the cost of your new heater. Electric heating units are the most affordable but also tend to be the most expensive to run. Gas heaters are cheaper and cleaner running than oil.

We know needing a new heater in Carol Stream gives you a lot of things to consider. But you won’t be making this decision alone. Our local HVAC experts will present you with a number of options that fit your budget and your home. Rest assured that our top concern is your comfort, not our bottom line or inventory. If affordability is a problem, check out our promotions and financing pages.

Don’t Waste Your New Heater Investment

Whether your unit is brand new or a few years old, annual heater maintenance will keep it operating at peak efficiency. When we install your new heater, ask if we’re offering any tune-up and maintenance incentives with it. During these regular preventive visits, our HVAC technician will run through an extensive checklist that includes everything from wiring inspections to burner cleaning and filter replacement. By ensuring all obstacles to operation are removed, we make staying warm easy and hassle-free. To learn more about our HVAC maintenance program in Carol Stream, give (630) 283-7981 a call.

Cost-Effective and Fast Furnace Replacement
Excellent experience with Gray's. They provided a very competitive quote to replace my furnace, and once I gave them the go-ahead, they had a technician on site within 15 minutes—that level of responsiveness is rare. The team was professional, efficient, and easy to work with throughout the process. Highly recommend Gray's for anyone looking for fast, reliable, and fairly priced HVAC service.

Excellent Residential and Commercial Furnace and AC Service
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. When it came time to replace my furnace, their expertise with our complex setup made it an easy decision to trust them with such a significant investment. Professionally, the company I work for also relies on Gray's to provide reliable and cost-efficient service to nearly 200 condo associations across the Chicagoland area. Their staff is friendly, knowledgeable, helpful, and patient — truly a pleasure to work with.
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.
