Sales. Service. Installation. Maintenance.
Those four words apply to every system below. Pick the one that is acting up, or the one you are planning to replace, and call (708) 717-2772 any hour.

Furnaces
Maintenance, repairs, installation and sales. An 80% AFUE furnace turns 80% of the gas it burns into heat. A high-efficiency gas furnace runs 90% or higher, up to a maximum of 98.5%.
Furnace repair, AFUE and installs
Air conditioning
Maintenance, repairs, installation and sales. Units come in SEER ratings from 13 up into the 20s, and a 20 SEER system gives you twice the efficiency of a 10 SEER one.
AC repair and SEER explained
Boilers
Maintenance, repairs, installation and sales. A boiler over 25 years old runs about 60 to 70% efficient. Yearly clean and checks help keep it from sliding there.

And the rest of the building.
Humidifiers and hot water tanks sit next to the furnace. Floors, ducts and pipes are the work around it.
Humidifiers
Whole-house units that ride on the furnace or air handler, for dry Chicagoland winters. Maintenance, repairs, installation and sales.
Hot water tanks
The water heater that shares the utility room with your furnace. Maintenance, repairs, installation and sales.
Radiant heat
Tired of cold floors and feet all winter long? Heat in the flooring keeps it warm and carries heat up into the room.
Custom sheet metal work
Remodeling or building a house, restaurant or store? We design the ductwork so each area is comfortable.
Piping
Leaky and rotten water pipes. Climaxx will be more than happy to help.

SEER stands for seasonal energy efficiency ratio. Air conditioners range from 13 SEER up into the 20s, and the higher the number, the more efficient the unit. A 20 SEER system gives you twice the efficiency of a 10 SEER unit.
AFUE is the share of the gas a furnace burns that becomes heat in your home. An 80% AFUE furnace turns 80% of its gas into heat. High-efficiency gas furnaces run 90% AFUE or higher, up to a maximum of 98.5%.
As a rough guide: a boiler over 25 years old runs about 60 to 70% efficient, a 20 year old boiler about 75%, and a 10 to 15 year old boiler about 80 to 85%. Yearly maintenance, cleaning and checks play a big role in keeping it there.
No. One reviewer wrote that Justin gave a fair price and did not try to sell him on replacing the entire unit. If a repair fixes it, that is what we recommend.
