What Does Furnace Repair and Replacement Actually Include?

Furnace repair is the hands on work of diagnosing and fixing problems inside your heating system so warm air flows through your home again. Furnace replacement is the full removal of a worn out or failing unit and the installation of a new, properly sized furnace in its place.

Your furnace is built from parts that work together under pressure every time the thermostat calls for heat. The blower motor pushes air across the heat exchanger, which warms that air before it travels through your ductwork and into every room. The ignitor lights the burners. The flame sensor confirms the fire is safe. The control board runs the sequence. When even one of these parts breaks down, your house goes cold.

At Infinity Air Heating and Cooling LLC, our certified furnace technician team handles every type of residential furnace repair, commercial furnace repair, gas furnace repair, electric furnace repair, and oil furnace repair across the Phoenix Valley. We also perform complete furnace installation service and new furnace installation when your current unit is beyond saving.

Whether you need a quick furnace ignitor replacement, a full furnace heat exchanger replacement, or a brand new high efficiency furnace installation, we do the job right and stand behind it.

Warning Signs That Tell You Something Is Wrong With Your Furnace

Desert winters hit harder than most people expect. When your furnace acts up, you feel it fast. Here is what homeowners across Phoenix, Tempe, Chandler, Gilbert, and Mesa tell us right before they call:

  • “The furnace clicks but no heat comes out.” This usually points to a failed furnace ignitor replacement or a dirty furnace flame sensor. The system tries to start but cannot complete the cycle. Every failed attempt wastes gas and wears out other parts.
  • “My heating bill jumped and we did not change anything.” A drop in efficiency means something is forcing your furnace to run harder. A cracked heat exchanger, a weak blower motor, or a clogged furnace air filter can all drive up costs without you knowing.
  • “There is a strange burning smell when the furnace kicks on.” Dust buildup is normal at first startup each season. But a lasting smell could signal electrical trouble, an overheating motor, or worse. Do not ignore it.
  • “Some rooms stay warm but others feel freezing.” Uneven heating often comes from furnace ductwork repair issues, a failing variable speed blower, or a system that was never sized right for your home. A proper furnace diagnostic service will show exactly where the breakdown is.
  • “The furnace keeps turning on and off every few minutes.” Short cycling strains every part of the system. The cause could be a bad thermostat, a dirty sensor, or an airflow restriction. The fix is usually simple, but waiting makes it expensive.
  • “Our furnace is over 15 years old and repairs keep adding up.” At some point, another repair is just throwing money at a dying machine. That is when a furnace system replacement with a modern energy efficient furnace starts saving you real money.

If you recognize any of these, your furnace is asking for help. Call before a small fix becomes a full replacement.

How Our Furnace Repair Service Gets Heat Back in Your Home

When you call Infinity Air about a furnace problem, you speak to a real person who listens and books your visit right away. We offer same day furnace repair and emergency furnace repair because cold nights in the desert do not wait for business hours.

Thorough Furnace Diagnostic

Our furnace repair technician shows up on time with the tools and parts to handle most jobs in one trip. We run a complete furnace diagnostic service that checks your ignitor, flame sensor, heat exchanger, blower motor, thermostat connection, gas valve, control board, and ventilation path. We do not stop at symptoms. We track down the root cause.

Clear Answers Before Any Work Starts

After the diagnostic, we sit down with you and explain what we found in plain words. We show you the worn or broken part if possible. We give you a written price and let you decide. No clock pressure. No scare talk. That is how a real furnace repair company treats people.

Targeted Repairs for Every Component

We handle furnace blower motor repair, furnace ignitor replacement, furnace heat exchanger replacement, furnace thermostat repair, furnace pilot light repair, and forced air furnace repair across all makes and models. If your gas furnace, electric furnace, or oil furnace can be fixed safely, we will fix it.

Full Replacement When Repair No Longer Makes Sense

Sometimes a furnace is too old, too damaged, or too costly to keep running. When that happens, our team walks you through the furnace replacement process. We handle furnace capacity sizing, removal of the old unit, new furnace installation, connection to your existing ductwork, and full system testing. We install standard and high efficiency furnace models based on what fits your home and your budget.

Post Service Walkthrough

After every repair or installation, we test the system, check airflow in every room, and explain what we did. We also talk about annual furnace maintenance so the same problem does not come back next winter. Every job is backed by our warranty on parts and labor.
