Nothing is more frustrating than entering your Raleigh, NC home and finding your heating or air conditioning not working as it should. Is the air not cooling as much as you'd like? Is your furnace blowing cold air? When comfort issues arise, the typical question on a homeowner's mind is: "Is it my thermostat, or is there a bigger issue with the HVAC system itself?" Pinpointing the culprit will save you time, money, and unnecessary stress.
At Ultra Air Heating & Cooling, LLC, we understand these frustrations. We make our business offering affordable, quality HVAC repair and replacement to the people of NC, and that includes master diagnosis of both thermostat and system problems. Whether you need furnace repair in Raleigh, NC, or an AC repair, knowing some basic troubleshooting steps can help you identify the problem before you call an expert.
Your thermostat is the brain of your heating and cooling system. It's what detects the indoor temperature, receives your desired settings, and informs your furnace or air conditioner to start or shut off. Due to its central position, a malfunctioning thermostat can very easily mimic the symptoms of a much larger system problem, creating confusion and unnecessary alarm.

A new thermostat or thermostat repair may be all you need to regulate temperatures in your home or office, but first, let's see if it's the source of your troubles.

No, a smart thermostat can optimize your system operation and make it more efficient, but it will not fix mechanical, electrical, or refrigerant issues within the HVAC unit itself. It is a control system, not a repair tool.
It's a wise decision to change your thermostat batteries at least once a year, normally during your spring or fall HVAC maintenance, even when the low battery light is not yet on.
If your AC is blowing hot air, it could be due to a clogged air filter, tripped circuit breaker, frozen evaporator coil, or refrigerant leak. This is generally a system issue that must be professionally diagnosed.

The Thermostat: Your HVAC's Command Center
Your thermostat is the brain of your heating and cooling system.

Common Heating and Cooling Issues and Initial Checks
When you have an issue, start with these simple checks to allow you to narrow down if it's a system issue or a thermostat issue:
1. No Heating or Cooling At All
Thermostat Check
- Is the thermostat switched to "Heat" or "Cool" (depending on the time of year) and at a temperature that would actually require heating or cooling (i.e., set to 70°F when the room temperature is 75°F for cooling)?
- Is the fan on "Auto" (as it normally should be in operation) or "On"? If it is on "On", and there's no air movement, that's a problem.
- Are batteries dead? Most digital thermostats, including wired thermostats, use batteries for display and programming. A blank or "low battery" indication is a strong clue.
System Check
- Go to your indoor (furnace/air handler) and outdoor (AC condenser) units. Is the power switch in the "On" position?
- Inspect your home electrical panel. Has the circuit breaker for your furnace or air conditioner tripped? Reset it once. If it trips again immediately, do not reset it again; this is a serious electrical issue.
- For the outside AC unit, is it clear of excessive debris (leaves, grass clippings, overgrown bushes) that could be blocking airflow?
2. Uneven Heating/Cooling or Individual Rooms Uncomfortable
Thermostat Check
- Consider its position. Is the thermostat in a place where it's exposed to direct sunlight, near a heat-producing appliance, or located in the vicinity of a drafty door/window? It will cause it to read inaccurately, leading to unbalanced comfort elsewhere.
- If you're using a zoned system, ensure the thermostat for the concerned zone is correctly set and the zoning dampers are functioning.
System Check
- Are all the supply and return vents in the affected rooms open and unobstructed?
- How long has it been since you changed your air filter? A clogged filter restricts airflow to certain areas.
- Is your ductwork physically damaged, disconnected, or leaking? Leaking ducts can lose conditioned air along the route to its destination. Ultra Air Heating & Cooling, LLC offers effective and reliable air duct repair services.
3. System Constantly Running (Short-Cycling or Long Cycles)
Thermostat Check
- Is the thermostat correctly set? Has it been accidentally set to a very low or high temperature?
- If you have a learning thermostat, has it just gone through a learning phase that might be inaccurate?
System Check
- A system that's too big or too small will cause short-cycling (too big) or long cycles (too small).
- Low refrigerant in an AC system will result in constant running but no cooling.
- A dirty indoor evaporator coil or outdoor condenser coil will make the system work harder and longer.
4. System Not Responding to Settings
Thermostat Check
- Does the display work but the unit just won't respond to temperature changes or mode changes? It could be an internal thermostat fault.
- Are the thermostat's internal wires corroded or loose? (Only examine if you know basic electric safety, and turn off power first).
System Check
- This is generally a control board issue in the HVAC unit itself, or a faulty sensor in the primary system.
When It's Likely to Be a Thermostat Issue
Having performed the preliminary checks, the following are all good indications that your thermostat is at fault:
- Blank or Flashing Display: Dead batteries are usually the cause.
- Unresponsive Buttons: Buttons don't respond to being pressed.
- Inaccurate Temperature Readings: The thermostat temperature reading differs considerably from other thermometers in the same room.
- AC/Heat Cycles On/Off at Random Intervals: Despite programming correctly, the system operates at random intervals.
- System Runs Continuously: The unit does not shut off even after the programmed temperature has been attained.
- No Power to Thermostat: For a wired thermostat without batteries, a blank display can also mean a wiring issue or a tripped circuit breaker for the thermostat circuit specifically (less common).
- Self-Fixable Check: The easiest do-it-yourself repair is to replace the batteries. If that doesn't work, ensure that it is clean and free of dust. If it is still not functioning correctly, professional installation or thermostat repair may be required. Ultra Air Heating & Cooling, LLC can perform this.
When It's Likely a System Issue (and Time to Call Ultra Air Heating & Cooling, LLC)
If your thermostat appears to be functioning properly (showing information correctly, responding to instructions) but your heating or cooling issues remain, the problem almost definitely is with your HVAC system itself. This is the time when it is important to get a professional for heating and cooling repair in Raleigh, NC.
Some indications of a system problem are:
- Unusual Sounds: Grinding, banging, squealing, or constant humming coming from the indoor or outdoor unit.
- Burning Smells: Dusty or electrical burning smells from the vents or unit.
- Water Leaks: Unusual water pooling around your indoor furnace/air handler unit.
- Ice on Coils: Ice on the outdoor AC lines or indoor evaporator coil.
- Repeated Breaker Trips: If your circuit breaker trips every time your system tries to start.
- No Airflow: The fan is running, but no air or very little air comes out of the vents.
- Warm Air from AC/Cold Air from Furnace: The system is operating, but not delivering the intended conditioned air.

Frequently Asked Questions (FAQs)
1. Can a smart thermostat eliminate all my HVAC problems?

3. What does it indicate if my AC is blowing warm air?
If your AC is blowing hot air, it could be due to a clogged air filter, tripped circuit breaker, frozen evaporator coil, or refrigerant leak. This is generally a system issue that must be professionally diagnosed.
4. Is uneven heating/cooling always a system issue, or can it be my ducts?
Uneven heating or cooling can be a system problem (i.e., incorrect sizing, low refrigerant) but is very often the result of issues with your ductwork, such as leaks, blockages, or poor design. Ultra Air Heating & Cooling, LLC offers air duct repair.
