24/7 Emergency Service

A furnace that runs past 15 years is working on borrowed time. The heat exchanger metal fatigues, the ignitor and flame sensor wear out more often, and efficiency drops as internal components lose tolerance. When repair bills start stacking up during a Skokie winter, replacement usually makes more financial sense than another patch. That is the point where All Temp Heating & Air Conditioning steps in to help you choose, size, and install a furnace built to last another two decades.

Signs Your Skokie Furnace Is Ready for Replacement

Many homeowners wait until a furnace fails completely before thinking about a new one. That approach often forces a rushed decision during a cold snap, when equipment demand is highest. Watching for early warning signs gives you time to plan the gas furnace replacement properly and select the right system for your home.

We encourage Skokie residents to pay attention to how their heating system behaves through the season. Small changes in performance often point to a system nearing the end of its service life. Below are the indicators we see most often when we evaluate an aging furnace.

  • Age past 15 years: Older furnaces lose efficiency and become harder to find parts for, especially discontinued models.
  • Rising energy bills: A furnace working harder to produce the same heat drives up your monthly gas costs.
  • Frequent repairs: When repair costs approach half the price of a new unit, replacement is the smarter investment.
  • Uneven heating: Cold spots in certain rooms often mean the furnace can no longer distribute air evenly.
  • Yellow burner flame or soot: A flame that burns yellow rather than blue can signal incomplete combustion and possible carbon monoxide concerns.

If several of these apply to your system, it is worth a conversation with our team. We give honest assessments and never push a replacement when a repair still makes sense for your situation.

Choosing the Right Gas Furnace for Your Home

No two Skokie homes heat the same way. Square footage, insulation quality, window count, ceiling height, and even the direction a house faces all affect how much heating capacity you need. A furnace that is too small will struggle on the coldest nights, while one that is oversized will short-cycle, wearing out components early and wasting fuel. Correct sizing is the single most important step in a furnace replacement, and we take it seriously.

Our technicians perform a heat load calculation rather than relying on the size of your old unit. The previous furnace may have been mismatched to the home in the first place, or your insulation and windows may have changed over the years. This calculation gives us the actual British Thermal Unit (BTU) output your home requires, so the new system runs efficiently and comfortably.

Once sizing is settled, we help you weigh efficiency ratings. Furnace efficiency is measured by Annual Fuel Utilization Efficiency, or AFUE. A standard modern furnace often falls in the 80 percent AFUE range, while high-efficiency condensing furnaces reach 90 to 98 percent. Higher AFUE units cost more upfront but return savings on gas bills across a Chicago-area winter. Other choices we walk you through include:

  1. Single-stage furnaces: These run at full output whenever they cycle, offering a dependable and budget-friendly option.
  2. Two-stage furnaces: These operate on a lower setting most of the time and switch to high output only on the coldest days, improving comfort and efficiency.
  3. Modulating furnaces: These adjust output in small increments to hold a steady temperature, delivering the most even comfort and quietest operation.

As one of Bryant’s highest-rated dealers in the nation, All Temp Heating & Air Conditioning offers quality equipment across all of these categories. We match the furnace to your comfort priorities and budget rather than steering you toward a single product line.

Our Furnace Replacement Process From Start to Finish

A furnace replacement is a significant project, and a smooth installation matters as much as the equipment itself. Even a top-tier furnace will underperform if it is installed poorly. Our approach follows clear stages so you always know what to expect and your new system performs as designed.

We start with an in-home evaluation. A technician inspects your existing ductwork, gas line, venting, electrical connections, and the space where the furnace sits. We check for issues such as undersized ducts or improper venting that could affect the new unit. This step lets us give you an accurate quote with no surprises later.

On installation day, our crew protects your floors and work areas, then safely disconnects and removes the old furnace. We handle the disposal of the old equipment so you do not have to. Next we set the new furnace, connect the gas supply, run the venting, and tie the unit into your ductwork and electrical system. For high-efficiency condensing furnaces, we also install the condensate drain line that carries away the water produced during combustion.

Before we consider the job finished, we test and calibrate the system. This includes verifying gas pressure, checking the flame sensor and ignitor, confirming proper airflow, and measuring temperature rise across the heat exchanger to make sure it falls within the manufacturer’s specified range. We also test safety controls, including the limit switch and pressure switches, and confirm your thermostat communicates correctly with the new furnace. Finally, we walk you through the operation of your new system and answer any questions you have.

Why Skokie Homeowners Trust All Temp Heating & Air Conditioning

Replacing a furnace is not a purchase you make often, so it helps to work with a company that has earned a long track record in the community. All Temp Chicago Heating & Air Conditioning has become the first choice for tens of thousands of families throughout the Chicago and suburban areas. That reputation was built one careful installation at a time, and it is something we protect with every home we enter.

We remain a family owned and operated company.

When you call us for a furnace replacement, you deal with people who live and work in the same area you do and who understand what a Chicago winter demands from a heating system.

Our services reach well beyond furnaces. We sell and service air conditioning, boilers, air purifiers, humidifiers, ventilation systems, and water heaters, and we provide expert installation, tune-up, and repair for all of them. That breadth matters during a furnace replacement, because we can spot opportunities to improve your whole comfort system at once. For example, pairing a new furnace with a whole-home humidifier can make your home feel warmer at a lower thermostat setting, reducing the dry air that comes with heating season.

Whether your furnace has failed unexpectedly or you are planning ahead for an aging unit, our team is ready to guide you through the options and complete the work correctly.

The best time to plan a furnace replacement is before you need it.

That said, we understand that furnaces often fail at the worst possible moment, and we respond quickly when they do.

Reach out to All Temp Heating & Air Conditioning to arrange an evaluation of your current system. We will assess your home, recommend properly sized options, and give you a clear, straightforward quote.
