Choosing the Right Furnace by Fuel Type
Your first decision is easy: choosing the fuel type.
The most common source is natural gas. Your local utility company supplies fuel to your home through an underground gas line. The price of natural gas is relatively stable, so you don’t have to worry about cost fluctuations. Plus, you never need to worry about storage.
- If you have access to a natural gas line, we strongly recommend a gas furnace. These furnaces have proven their value over the years for providing steady comfort on the coldest of days.
- Oil furnaces are a popular alternative in the United States, particularly in parts of the Northeast that do not have easy access to natural gas. These types of furnaces last longer than gas furnaces but do not operate as efficiently. Oil prices fluctuate more than natural gas prices, making it harder to gauge your monthly expenses. Plus, you will need a storage tank for the oil.
- Electric furnaces tend to last longer than gas furnaces and cost less to install. On the other hand, they are more expensive to operate and take longer to heat your home. Anyone living in a cold climate would enjoy more comfort with a gas or oil furnace.
Choosing the Right Furnace Speed
Furnaces run at different speeds. The operating speed you choose will impact your comfort, budget, and indoor air quality (IAQ).
Single-stage furnaces have just two settings, on or off. Your furnace switches on and continues to run to reach the desired temperature. Once it reaches the temperature, the furnace turns off. Single-stage furnaces are the most affordable models and easiest to install. But they are the least efficient and tend to create hot and cold spots in larger homes.
Two-stage furnaces run at full speed and half speed. This allows your furnace to heat your home more evenly, producing a more consistent temperature from room to room. In addition to producing better heating, the half-speed setting is much quieter.
Variable-speed furnaces are the gold standard of the heating world. These models adjust their speeds to provide precise comfort. They run longer at slower speeds, improving efficiencies while lowering your energy bills. Because they do not frequently cycle on and off, these systems tend to have fewer breakdowns.
Variable-speed furnaces are much more adept in maintaining your indoor air quality, catching harmful particles, and eliminating excess moisture that causes mold growth. Larger homes benefit tremendously from variable-speed furnaces.
Choosing an Efficient Furnace
The AFUE (annual fuel utilization efficiency) rating on your furnace indicates how much energy it converts. An energy-efficient furnace with an AFUE rating of 95 can convert 95 percent of the energy it consumes into heat.
The higher the AFUE rating, the more money you save on monthly utility bills. Energy-efficient furnaces emit fewer greenhouse gases and make less noise when they operate. If you want to reduce your home’s carbon footprint, the perfect place to start is with your heating and cooling equipment!
How Much Money Can a New Furnace Save You?

Furnace Installation & Replacement in Mesa
A furnace is due for replacement when repairs keep adding up, heating bills climb, rooms heat unevenly, or the unit is 15 to 20 years old. The team at McCall’s Air Conditioning and Heating sizes the new furnace to your home, installs it correctly, and checks the ductwork it depends on, with financing available for approved credit.
Be sure to ask about our convenient financing options (subject to approved credit) designed to make it easy for you to create your dream home.
Furnace & Heating Repair in Mesa
When a furnace won't heat, blows cold air, short cycles, or makes odd noises, the cause is usually a failed igniter, a dirty flame sensor, a worn blower motor, or an airflow problem. Technicians from McCall’s Air Conditioning and Heating handle furnace and heating repair across Mesa and the East Valley, find the cause first, and replace a part only when it's needed.
Common Furnace Problems We Repair in Mesa
- Furnace won't turn on: a tripped safety switch, a failed control board, a dead thermostat, or a closed gas valve.
- Blowing cold air: a dirty flame sensor, a failed igniter, or a limit switch shutting the burners off.
- Short cycling: restricted airflow, a blocked vent, or a flame sensor that keeps dropping out.
- Banging, squealing, or grinding: a delayed ignition, worn blower motor bearings, or a loose panel.
- Weak airflow or uneven heating: a failing blower motor, a clogged filter, or leaking ductwork.
- Rising energy bills: dirty burners and worn parts make a furnace burn more gas for the same heat.
- Gas smell or a carbon monoxide alarm: leave the house first and call your gas utility or 911 from outside. A cracked heat exchanger needs a technician before the furnace runs again.
Why Furnaces Fail in Mesa in the First Cold Snap
Mesa furnaces sit idle for most of the year while the AC runs through a long summer. When the first cold morning arrives, dust has settled on the burners and sensors, and a part that was weak last winter finally gives out. Having the furnace looked at before the first cold snap is cheaper than finding the problem on a cold night.
What to Expect From a McCall's Furnace Repair
- A technician checks the thermostat, filter, igniter, flame sensor, blower, and airflow to find the actual cause.
- You hear what's wrong and what your options are before any work starts.
- McCall’s Air Conditioning and Heating replaces a part only when it's needed, or when we can show you a real cost saving.
- If the furnace is old or the repair is large, you also get an honest look at replacement and what it would involve.

Mesa Furnace Repair & Replacement Questions, Answered
Why won't my furnace heat or turn on?
Start with what you can check safely: the thermostat is set to heat and above the room temperature, its batteries are fresh, the filter isn't clogged, and the breaker hasn't tripped. If those check out and the furnace still won't start or the air stays cool, don't reset it repeatedly. The system may have shut itself down for a safety reason that needs a technician.
Why is my furnace blowing cold air?
Check the thermostat fan first. If it's set to "on" instead of "auto", the blower pushes unheated air through the ducts between heating cycles, which feels like cold air. If the setting is right and the air is still cold during a heating cycle, the furnace needs a diagnosis.
Why does my furnace keep turning on and off?
Check the filter first, since a clogged one is the most common trigger and an easy fix. If the furnace keeps cycling after that, don't wait. Repeated short cycles wear out the igniter and blower faster and leave the house heating unevenly.
How much does a furnace repair cost in Mesa?
Cost depends on the part, the labor, and the furnace's age. A flame sensor or igniter sits at the low end, while a blower motor, control board, or heat exchanger costs more. Ask for the repair quote next to the cost of a replacement before you decide.
Should I repair or replace my furnace?
A common rule of thumb is to replace when a repair costs about half the price of a new furnace or more, especially on an older unit. Because Mesa winters are short, a furnace sees fewer hours than one in a colder climate, so its age and condition matter more than how much it has run.
How much does furnace replacement cost, and how long does a furnace last?
Cost depends on the home's size, the furnace's efficiency (AFUE) rating, single-stage, two-stage, or variable-speed operation, and whether ductwork needs work. Most gas furnaces last 15 to 20 years with regular care. Replacing before the first cold nights, rather than after a failure in December, gives you time to compare options.
Should I choose a gas furnace or a heat pump in Mesa?
A gas furnace heats quickly and holds up on the coldest nights. A heat pump heats and cools with one system and suits Mesa's mild winters, so it's worth comparing if you're replacing both the AC and the furnace. Which one costs less to run depends on your electric and gas rates, so ask for both options priced side by side.
Do you offer emergency furnace repair in Mesa?
Yes. A furnace that fails on a cold night doesn't have to wait long, and technicians from McCall’s Air Conditioning and Heating respond to heating emergencies across Mesa and the East Valley.
