Central AC Installation

Choosing the Right Central AC System for Your Home

Summer in Chicago can turn a comfortable home into an uncomfortable one within hours. If your old air conditioner struggles to keep up during a July heat wave, cycles on and off constantly, or drives your energy bills higher every year, it may be time to consider a new central AC installation. Replacing an aging or undersized system is one of the most effective ways to restore reliable comfort, and getting the installation right from the beginning makes all the difference in performance and longevity.

At All Temp Heating & Air Conditioning, we approach every central AC installation as a complete project rather than a simple equipment swap. A modern central air conditioner is designed to work with your ductwork, your thermostat, your insulation, and the layout of your home. When each of these pieces is matched correctly, you get even cooling, quiet operation, and lower operating costs. When they are mismatched, you can end up with hot and cold spots, excess humidity, and a system that wears out years before it should.

Central air conditioning distributes cooled air through a network of ducts, using a matched outdoor condenser and an indoor evaporator coil. The refrigerant cycle removes heat from the indoor air and releases it outside, while the blower motor pushes conditioned air throughout the living space. Because so many components must operate in harmony, the quality of the installation directly affects how well the equipment performs for the next 12 to 15 years.

Why Correct Sizing Is the Foundation of a Good Installation

Many homeowners assume that a bigger air conditioner will cool a home faster and better. In reality, an oversized unit cools too quickly and shuts off before it can remove moisture from the air. The result is a home that feels cold and clammy, with the compressor short-cycling in a way that shortens equipment life. An undersized unit, on the other hand, runs constantly and never quite reaches the desired temperature on the hottest days.

To avoid both problems, we perform a load calculation before recommending any equipment. This process, often referred to as a Manual J calculation, evaluates the specific characteristics of your home so we can specify the exact cooling capacity you need. Factors we consider include:

• Square footage and ceiling height: The total volume of air that must be cooled throughout the day.
• Insulation and window quality: Poorly insulated walls and older windows allow more heat to enter, increasing the cooling demand.
• Sun exposure and orientation: Rooms facing west or south often carry a heavier cooling load in the afternoon.
• Ductwork condition and layout: Leaky or restrictive ducts reduce delivered airflow and affect capacity.

Central AC capacity is measured in tons, where one ton equals 12,000 BTUs of cooling per hour. Efficiency is measured using the SEER2 rating, with higher numbers indicating lower energy use. We help you weigh the upfront investment of a higher-efficiency system against the long-term savings on your monthly cooling costs, so the equipment fits both your comfort needs and your budget.

Our Central AC Installation Process From Start to Finish

A smooth installation depends on careful planning and skilled workmanship. When you schedule a central AC installation with All Temp Heating & Air Conditioning, we follow a consistent process designed to protect your home and deliver a system that performs as promised.

1. In-home assessment: We evaluate your existing equipment, ductwork, electrical service, and the location for the outdoor condenser, then complete the load calculation.
2. Equipment selection: We present matched system options, explain the efficiency and capacity of each, and help you choose the right fit for your home and budget.
3. Removal of old equipment: Our technicians safely disconnect and remove the existing condenser and evaporator coil, recovering old refrigerant in accordance with environmental regulations.
4. Installation of the new system: We set the condenser on a level pad, install the new evaporator coil, connect refrigerant lines, and integrate the system with your ductwork and thermostat.
5. Startup and testing: We charge the system to the manufacturer’s specifications, check refrigerant pressures, verify airflow, and confirm that the thermostat controls the equipment correctly.

Throughout each step, we pay attention to the technical details that separate a lasting installation from a rushed one. Refrigerant lines are properly sized and sealed to prevent leaks. The evaporator coil is matched to the condenser so that the two components operate at peak efficiency. Condensate drainage is routed correctly to prevent water damage, and the electrical connections are secured to code. These small details protect your investment and keep the system running quietly for years.

Applications Across Chicago-Area Homes

No two homes cool the same way, and our experience across Chicago, Bolingbrook, Skokie, Evanston, Lincolnwood, Morton Grove, Niles, Park Ridge, Woodridge, and Darien, IL has taught us how to handle a wide range of situations. Classic Chicago bungalows often present challenges with retrofitting central air into homes that were originally built for radiator heat. In these cases, we design duct routing and equipment placement that respects the character of the home while delivering even cooling to every room.

Newer suburban homes with existing forced-air heating are usually well suited for a straightforward central AC replacement, since the ductwork and blower are already in place. Larger multi-level homes sometimes benefit from zoning solutions that allow different floors to be cooled independently, reducing energy waste and improving comfort where the family spends the most time. For homes with humidity concerns, we can pair a properly sized system with dehumidification and ventilation upgrades that make the indoor air feel noticeably fresher.

We also install air purifiers and humidifiers alongside cooling equipment for homeowners who want to improve overall indoor air quality. Because we sell and service furnaces, air conditioning, boilers, air purifiers, humidifiers, ventilation, and water heaters, we can address your entire comfort system rather than a single component. This whole-home perspective helps us recommend solutions that work together instead of against each other.
