Common Heating Problems We Repair

No Heat or Cold Air

Furnace or heat pump runs but does not warm the home properly. 

Frequent Cycling

System turns on and off too often or cannot complete a normal cycle. 

Uneven Heating

Some rooms stay colder than others even while the system is running. 

Strange Noises or Odors

New sounds, burning smells, or unusual operation can point to a developing problem. 

Weak Airflow

Airflow feels weaker than normal or does not reach parts of the home properly. 

Thermostat or Electrical Issues

The system will not start, the thermostat is unresponsive, or the breaker keeps tripping. 

Furnace and Heat Pump Repair

Furnace Repair

Gas furnaces can develop problems with ignition, burners, airflow, venting, or system controls. If the furnace is blowing cold air, failing to ignite, cycling too often, or shutting down unexpectedly, we inspect the system to find what is causing the problem before recommending a repair. 

Heat Pump Repair

Heat pumps work differently from furnaces and can have issues with electrical components, refrigerant, defrost operation, airflow, or the outdoor unit. If the system is blowing lukewarm air, running constantly, or not keeping up, our team can trace the problem and explain what needs attention. 

When Should You Call for Heating Repair?

If the house is not warming the way it normally does, it is usually better to have the system checked before the problem gets worse. A heater that keeps running, turns on and off repeatedly, blows cool air, makes new noises, or suddenly uses more energy than usual is giving you a reason to take a closer look. 

Call for service if you notice: 

  • No heat or weak heat 
  • Cold air from the vents 
  • Frequent cycling 
  • New noises or odors 
  • Uneven room temperatures 
  • Breaker trips 
  • Thermostat problems 
  • Longer run times

Heating Problems That Need Immediate Attention

Some heating problems should not wait. Stop using the system and call for professional help if you smell gas, a carbon monoxide alarm goes off, a gas furnace will not ignite safely, or the heating system repeatedly trips a breaker. 

What to Expect During Heating Installation

A heating repair should leave you with a clear answer, not more questions. We start by listening to what the system has been doing, inspect the equipment, and test the parts most likely connected to the problem before recommending any work. 

 

1. Tell Us What You’re Noticing

We start with the symptoms you have noticed, such as cold air, short cycling, unusual noises, or trouble keeping the home warm. 

2. System Inspection and Testing

The new system is selected around your home, not just the size of the old unit. We consider the heating load, existing setup, fuel source, efficiency options, and how the equipment needs to work with the rest of your HVAC system. 

3. New System Installation

Our team installs the new furnace, heat pump, or complete HVAC system and completes the connections required for that setup, including ductwork, electrical, gas, refrigerant, venting, and controls where applicable. 

4. Startup and Performance Testing

Before we consider the job finished, we start the system and check that it is operating properly. That includes airflow, thermostat response, heating performance, and the safety controls tied to the equipment.

Repair or Replace Your Heating System?

A repair is often the right call when the system is otherwise in good condition and the problem can be fixed at a reasonable cost. Replacement may be worth discussing when the equipment is older, breakdowns are becoming more frequent, or a major repair would mean putting a significant amount of money back into a system that is already declining. 

Our team can explain what we find and give you a clear picture of both options. If replacement makes more sense, we can also help you compare furnaces, heat pumps, and other heating installation options without pushing you toward equipment you do not need.

5 Stars ⭐⭐⭐⭐⭐
​Alabama Climate Control truly prides themselves on quality customer service. As a customer who was overly frustrated because my AC went out at the most hotest time of the season; they immediately understood my needs and concerns. They treated me with the utmost respect, genuine concern, and care.
​Not to mention, I contacted their after-hours department, and before I could even leave a message, someone was already returning my call—that’s award-winning customer service if you ask me! The original HVAC tech who answered assured me he’d have the office contact me first thing in the morning, and they proved they are a company of their word when I received that phone call right on schedule as promised.
​I was greeted with a prompt call from Ms. Nori—again, customer service above reproach—followed by the technician, Jeremy, who called prior to arriving and communicated every single step of the way. Jeremy went above and beyond, which clearly shows how passionate he is about his profession.
​If you’re searching for a reputable company, look no further. Alabama Climate Control treats you like more than just a customer—they treat you like family! 😉

Get Your Heat Working Again

A heating problem rarely gets more convenient with time. If your furnace or heat pump is not keeping the house comfortable, let us take a look before a small issue turns into a larger repair. We will inspect the system, explain what we find, and give you a clear path forward. 

Frequently Asked Questions

A furnace blowing cold air can point to several issues, including a dirty or failing flame sensor, an ignition problem, an overheated system that has tripped a safety limit, or a gas valve issue. A clogged filter can also contribute to overheating and shutdowns. If the system keeps blowing cold air, our technicians can inspect it and find the cause. 

If the burner will not ignite, the problem may be a dirty or failed flame sensor, a faulty ignitor, or a pressure switch issue. Modern furnaces go through several safety checks before ignition, and if one of those checks fails, the system may lock out and refuse to fire. A technician can test the ignition sequence and identify what is stopping the furnace from starting properly. 

A faint burning smell when you first turn the heat on for the season can be normal. Dust can collect on heating components during months of inactivity and burn off once the system starts running again. If the smell is strong, does not go away, or smells like burning plastic or electrical wiring, turn the system off and call for an inspection. 

Yes. A cracked heat exchanger can be a serious safety concern because it separates combustion gases, including carbon monoxide, from the air circulating through your home. If a crack is found, the furnace should not be operated until the issue has been properly addressed. 

Heat pumps usually produce air that feels warm rather than intensely hot because they move heat instead of creating it through combustion. That can be completely normal. If the system is struggling to maintain the thermostat setting, however, the issue could involve refrigerant, the reversing valve, backup heat strips, or another system component. 

A furnace that repeatedly trips the breaker may have a blower motor drawing too much current, an overloaded circuit, or a problem with the breaker itself. You can reset the breaker once, but if it trips again, do not keep resetting it. Call a technician to inspect the furnace and electrical supply so the cause can be identified safely.
