Energy Efficient Air Conditioners Near You

An air conditioning system repair or tune-up can sometimes make it feel like new again. You’ll probably notice the difference right away because the air will feel fresh and constant throughout your home. Later, you might notice a difference in your utility bills because the fault was increasing the unit’s energy usage. So, how will you know if your unit needs a repair or AC maintenance?

Whether you’re looking for a replacement air conditioner, a repair, or a tune-up, it’s best to hire a company with experience. A trusted contractor’s technicians will be able to identify the cause of every strange noise, smell, or leak.
They’ll know how to fix them and only use high-quality parts that last longer than cheap alternatives. If the problem’s a malfunctioning thermostat, the technicians will know what the fault is and how to fix it.

If it’s a tune-up, they’ll spot potential issues, make necessary adjustments and ensure your system works at its best. Whatever the issue, look for a company that’s a member of the Air Conditioning Contractors of America (ACCA). Its members are held to a high standard of excellence, so you’ll know you’re dealing with a respected contractor.

Frequently Asked Questions

Q: What SEER rating should I look for when buying a new air conditioner?

A: SEER stands for Seasonal Energy Efficiency Ratio and measures how efficiently an air conditioner uses energy. A higher SEER rating means lower monthly operating costs. TR Miller carries a range of central AC units from 13 SEER single-stage models to 20 SEER variable speed dual compressor systems. For most Greater Chicago homeowners, a 16 SEER or higher unit offers the best balance of upfront cost and long-term energy savings. Our technicians can help you select the right efficiency tier for your home and budget.

Q: What are the signs that my air conditioner needs to be repaired or replaced?

A: Common signs your AC needs professional attention include weak airflow from the vents, the home not cooling to the set temperature, unusual noises or strange odors from the system, and a noticeable increase in monthly utility costs. A repair or tune-up can often restore an underperforming system to like-new condition. However, if your unit is more than 15 years old or repair costs are adding up repeatedly, replacement with a newer energy-efficient model is likely the more cost-effective long-term decision.

Q: Are there rebates available on new air conditioner installations?

A: Yes. TR Miller carries several AC models with Home Comfort Rebates available, including the Speed Platinum 20, Speed Platinum 18, Gold 17, Silver 16, Silver 14, and Silver 13 units. Rebate availability and amounts can change seasonally, so contact TR Miller to find out which current rebates apply to the system that fits your home and budget.

Q: What is the difference between a central air conditioner, an air handler, and a ductless mini split?

A: A central air conditioner cools your entire home by distributing conditioned air through a ductwork system. An air handler works alongside a central AC or heat pump to circulate that conditioned air through the ducts. A ductless mini split system has no ductwork — it uses an outdoor compressor connected directly to one or more indoor units, allowing for zone-by-zone temperature control in specific rooms. Mini splits are ideal for homes without existing ductwork, room additions, garages, and spaces that are difficult to cool with a central system.

Q: How often should I have my air conditioner serviced?

A: Once per year — ideally in spring before cooling season begins. An annual AC tune-up keeps your system running at peak efficiency, extends its lifespan, and gives a technician the opportunity to catch developing problems before they cause a breakdown on the hottest day of summer. TR Miller recommends scheduling maintenance before the first heat wave so your system is fully inspected and any repairs can be addressed while parts and scheduling are readily available.
