Fast & Reliable AC Installation in Highland Park
At some point, repairing your AC unit becomes cost-prohibitive, and it makes financial sense to replace your failing Air Conditioner with a NEW, high-efficiency system with a 10-year warranty. Extreme Comfort Advisors are trained to explain the cost-benefit analysis of repairing vs. replacing your existing Air Conditioning System and are happy to help you review all the options, even if that means repairing your existing system to get “just one more summer” out of it. We understand. We want to help you make the best decision for your family. Call an Extreme Comfort Advisor today for a FREE, no-obligation estimate for a new system.
Selecting A New Air Conditioner
Most of the time, when people refer to their air conditioner, they talk about the entire AC system, including the outdoor condenser, the furnace, and the indoor coil. These three components make up a complete Air Conditioning system.
Selecting a NEW AC System can be overwhelming, but we are here to help make it simple. There are three main areas to consider when choosing a new system:
- Efficiency: measured by a SEER rating. SEER stands for Seasonal Energy Efficiency Ratio and measures how efficiently an air conditioning system uses electricity. It is like a miles-per-gallon rating on new cars. The key to a SEER rating is that it measures how efficiently the matched AC system uses electricity. In other words, installing a new 22 SEER outdoor condenser with an older indoor coil and furnace will not achieve a 22 SEER rating.
- Features: New AC Installations range from a conventional single-stage system to a variable-speed system that can increase comfort and reduce energy costs.
- Budget: We respect that you work hard for your money, so we always have your family’s best interests in mind when we make repair or replacement recommendations. If you have a budget in mind, we will always try to work within those parameters.

How does the $5000 rule help with AC decisions?
The $5000 rule is simple: multiply the cost of the repair by the age of the unit. If that total exceeds $5000, it might be time to consider a replacement. We’ll provide an honest assessment so you can decide what’s best for your home and budget.
Do you have an Air Conditioning Emergency in Highland Park?
If you are experiencing any of the air conditioning issues described below, call Extreme Comfort right away, and we will dispatch an AC Repair technician to help fix your problem.
- Unusual or loud noises from your outside AC unit or furnace: A properly functioning air conditioning system makes a smooth, consistent noise when it is running; however, clanking or banging sounds from your system indicate a loose or damaged part. Address this issue IMMEDIATELY. Failing to repair a damaged part could lead to a more costly repair or a full AC system replacement.
- AC Blowing Hot Air: The first sign of trouble usually appears when your AC system no longer cools and only blows hot or warm air. Most of the time, this is a simple refrigerant or Freon issue that an AC repair service call can easily fix.
- Leaking Air Conditioners: A little condensation around your outside AC unit on a humid day is not unusual; however, standing water or pebbles collecting under your HVAC system can signal a refrigerant leak that may need repair. With refrigerant (Freon) prices, the sooner you fix a leak, the less expensive the AC repair will be.
- Unresponsive Thermostat: Is your thermostat blank or reading 72°, but your home is hot and humid? This can signal a failing thermostat, but the good news is it is usually a quick repair.
- Unpleasant or Burning Smells: Burnt wiring is a sign of a potentially dangerous issue that could lead to an electrical fire. If you smell something burning coming from your air conditioning system, shut off your AC immediately and call for emergency service.
Save Money With Preventative Maintenance
Manufacturers require annual check-ups to keep your warranty valid because a properly maintained AC system often outlives the warranty, unlike a system that goes unchecked year after year. Therefore, air conditioning and heating system check-ups twice a year not only help maintain your manufacturer’s warranty, but they will help identify minor problems before they become expensive repairs. You can rest easy as the summer heat melts Highland Park, knowing your investment is protected by the Comfort Club.
