Your HVAC system provides year-round comfort in your home, but occasionally it may experience problems that need professional assistance. Knowing how to troubleshoot these issues quickly may allow you to get them fixed before they become more severe. We have prepared a detailed troubleshooting procedure guide for HVAC systems to ensure your home runs smoothly. Moreover, we will highly recommend that you contact an experienced HVAC professional for the troubleshooting process to make sure your HVAC system gets the best possible care.
No Power to the HVAC System
One of the most frequently experienced HVAC issues is when the system won’t power on. This usually indicates a power issue; therefore, technicians should start inspecting the breaker/fuse box to address this problem.
- If a breaker or fuse has tripped, your unit may shut off.
- To restore power to it, just flip back the switch.
- If necessary, try replacing the fuse for more efficiency.
- Usually, this should solve your issues, though if not, it might require professional assistance to resolve.
Thermostat Not Working Properly
The thermostat is at the core of any HVAC system and is essential in creating an ideal indoor climate. Issues related to it could range from power issues or sensor malfunctions to simple thermostat settings errors or simply being outdated. A thermostat that’s not functioning as expected is often due to power source issues.
To rectify this situation, try swapping out batteries and making sure the circuit breaker has not been tripped. Remember that your thermostat may not be compatible with your HVAC system, leading to communication problems between devices and improper heating or cooling. In such a case, professional service should be hired to inspect and repair the thermostat.
HVAC Unit Not Heating or Cooling
Homeowners frequently discover that their HVAC unit isn’t heating or cooling efficiently. Various issues, including clogged air filters, thermostat issues, or refrigerant leakage, could cause this inadequate cooling. Most often, though, this HVAC problem can be fixed through routine maintenance.
Electrical problems, such as tripped circuit breakers or wiring issues, may prevent your system from working effectively and require resetting to restore functionality. In such instances, resetting may be necessary to get things back in working order.
Another common problem is when the power switch of your unit isn’t on, making for an easy fix that may save money in service calls.
Uneven Airflow in Different Rooms
If some rooms feel cooler while others seem warmer, this could indicate that your HVAC system is mis distributing air. Uneven temperatures cause hot and cold spots throughout your house, increasing energy costs. Make sure all vents are open and unblocked. This may seem obvious, but how quickly people close (fully or partially) vents without realizing it can be surprising!
Check your air filter regularly. A dirty air filter restricts airflow and could prevent your forced-air system from operating efficiently, so make sure it remains clean by periodically replacing or cleaning it out. This will allow your furnace and AC systems to run more efficiently while helping lower energy costs.
Unusual Noises from the HVAC Unit
Winter nights can be filled with the comforting sound of an HVAC system’s familiar hum, yet if it makes any strange sounds, this could be its way of communicating that something is amiss and requires attention.
Roaring noises could be caused by loose screws or panels, debris in the blower or worn-out motor belts hitting metal objects. If it sounds similar to a tapping noise instead, this could indicate wear on one or both motor belts and even signal that one has come loose from its seat in your motor vehicle.
In these instances, calling in a professional HVAC technician for diagnosis is typically the best course of action; however, performing some basic troubleshooting steps yourself may help identify the source of your issue and take necessary measures to address it.
Air Filter Clogged or Dirty
Air filters are essential components of HVAC systems. They help ensure optimal operation by filtering out dust, dirt, and other particles that could otherwise compromise system components and create discomfort in your home. Filters that become dirty restrict airflow, forcing your system to work harder than necessary, leading to higher energy bills and reduced efficiency.
Reusable filters should be vacuumed or submerged in soapy water to remove debris, then rinsed and dried before replacement. If your filters seem to get clogged more frequently than normal, this could be a telltale sign that duct leaks or improper airflow dynamics require professional attention. These issues need professional treatment to be solved successfully. Here’s a complete guide for clearing the clogged air filters.
Leaking Water from the HVAC System
When running, air conditioners generate condensation, or water. This runs down the indoor evaporator coil into a drain line outside for disposal; if it becomes blocked or clogged, it could lead to severe flooding within your home and damage.
Many systems utilize a condensate heat pump that collects water in a drain pan and pumps it outdoors. If this pump fails, it can cause leakage into your home and overflow into other rooms.
If your HVAC system is leaking water, it is critical to check and clean up any visible signs of moisture as quickly as possible. Next, contact a professional HVAC maintenance company, Green Street HVAC.

Underestimating your HVAC skills or knowledge could prove dangerous and lead to injury, property damage, or the nullification of equipment warranties. Always consult a licensed technician before performing repairs on an HVAC system.
Methodical troubleshooting should be employed to effectively pinpoint their sources; when looking into each potential source, make sure you look carefully into each potential cause before ruling them all out until you find your actual issue. To get started, read on for some valuable tips for troubleshooting common HVAC issues.
