Install, Repair & Maintain

We offer air conditioning service, repair, and installation for all your needs. Your air conditioner is one of the most expensive purchases you will make for your home, so make sure you use the best in the Fox Valley for your HVAC needs.

24-7 Repair services

We specialize in American Standard, but we service all makes and models. Our trained, skilled and certified technicians can accurately diagnose your A/C problem and repair it for you as quickly as possible.

We strive to reduce stress and inconvenience to our customers when their costly air conditioner needs repair. We will keep a clean work area, straighten up after a repair job, and take way old parts when leaving a repair call.

When your air conditioner breaks down in these hot, humid Midwest summers, you can trust your repair to our dependable veteran owned company. We offer 24/7 emergency service, so even on those hottest weekends of the year, we are there to keep you cool.

Regularly Scheduled Maintenance

Air conditioning maintenance is important to keep your system running at peak efficiency. If your air conditioning system has to work harder because it is dirty, then your energy bills will increase and your A/C will not work at its maximum efficiency.

Maintenance can prolong the life of your system. Call Leith Heating & Cooling to get regular maintenance and you can increase the life span of your A/C unit from 30% to 50%. An average unit has a life span of 12 to 15 years if not maintained annually.

Regular maintenance from Leith Heating & Cooling can save your air conditioner from frequent breakdowns. Improperly maintained air conditioners can lead to larger issues that could lead to expensive emergency repairs. We have trained technicians that can often predetermine the problems with expertise, experience, and advanced diagnostic tools. That way we can make sure your A/C is operating at its peak performance and ready for the hot, humid Chicagoland summers.
