Signs Your AC Needs Repair

When your air conditioner stops working at the wrong time of year, your home can quickly become unlivable. Make sure you know the signs of air conditioner issues requiring repair, so you can call Comfort Zone Service as soon as something goes wrong:

  • You have frozen evaporator coils.
  • You’re getting lukewarm or warm air.
  • Water is draining where it shouldn’t be.
  • Your air conditioner won’t turn off.
  • You hear strange noises.
  • You have high humidity or poor air quality.

Need AC repair soon? Call (708) 403-3434 or contact us online to schedule a free service call as soon as possible.

Installing & Replacing Your AC Unit

Eventually, every air conditioner needs to be replaced. The average unit, cared for properly with annual maintenance, can last anywhere between 15 and 20 years if you’re lucky — but after 10 years, you might want to consider an upgrade for the savings due to energy efficiency and other technological improvements (to say nothing of potential lost efficiency as your unit ages).

When it’s time to install a new unit, make sure you have the Comfort Zone Service team to provide superior products, explain your options, and help you find the ideal air conditioner for your needs, preferences, and budget.

Furnace Installation & Replacement

When your furnace reaches the end of its life span — either by aging or due to a component failure that would be unreasonably expensive to fix — you want a team on your side that can guide you to the right replacement and install it with no fuss and no complications.

Whether you’re upgrading, replacing, or installing for the first time, Comfort Zone Service is ready to help you find and install the right furnace for your home.

Furnace & AC Tune-Ups

Without regular maintenance, you’re doomed to spend unnecessary money on your HVAC systems over time. That’s because maintenance keeps your systems running efficiently, controlling energy costs. It also lets you identify problems while they’re still cheap to fix, saving you on repairs or replacements.

Don’t let your systems go unnoticed over the years until you end up with an emergency; let our team perform annual maintenance on your furnace and air conditioner and keep them running well for their fullest life span.

Very quick response time! I noticed the failure of my hot water heater at 7 pm one evening and had a new hot water heater installed and ready to go by 11 am the next morning. Great communication, clear recommendations, and took the time to explain details about the equipment that was ultimately installed.

Ryan H.

We have worked with Comfort Zone for about 4 years and are completely satisfied with the quality of service they provide. They recommended and installed a new AC unit, and provide us an annual furnace and AC cleaning and inspection service. We highly recommend this company for residential heating and cooling needs.
