Getting your HVAC system regularly maintained is important, but it’s also important to make sure that it’s working properly at the right time of year. Even the best-maintained system can still fail at the wrong time. There are several things that you can do to keep your system running smoothly, and you can additionally seek help if it malfunctions.

Being clueless about a problem with your air conditioning, heating, or ventilation system can be frightening. If you feel it’s beyond your ability, it is always practical to call in a professional. First Response Heating and Cooling provide the most reliable and cost-efficient air conditioning service in Lakeland, FL.

Let’s begin by understanding your HVAC system

The term HVAC refers to heating, ventilation, and air-conditioning. Your air conditioner, heat pump, and furnace are all components of a complete system.

While it’s important to have an experienced HVAC professional diagnose and solve most issues, many simple problems can be easily solved.

First Response heating and cooling experts have listed a few tips for troubleshooting HVAC.

1) Start with The System Reset: One of the first steps to fix a problem is to reset the system. There are different methods for different types of heating and cooling equipment, such as air conditioners, heat pumps, and furnaces. Check your owner’s manual for the correct reset method.

2) Check The Power Supply and Switches: If your air conditioner is not working, it should be first checked to make sure that it is still getting power. It should also be looked into if the breaker is tripped or if it has a fuse blown. A faulty motor or compressor might be preventing the unit from properly running. Although it may seem unlikely, many HVAC problems can be solved by just a simple switch. Try to identify a potential issue by checking your system’s power supply. If it’s not working, try turning it back on by waiting a couple of seconds.

3) The Thermostat Setting: A faulty thermostat can cause various issues with your home’s heating and cooling system. One of the first steps to prevent this issue is to make sure that the device has power. Changing the batteries will also help prevent the system from going completely off.

Check for any setting changes in the thermostat. It could be caused by a child accidentally pressing the wrong button, or it could be because your device has reset. Also, make sure that all your settings are set correctly before you start using your new thermostat.

4) Cleaning or Replacing Filters: If your HVAC system is not working properly, it could be time to replace your air filters or maybe the filter is clogged. Try cleaning the filters or replacing them if they are really old. Doing so could help improve the quality of air in your home and prevent you from experiencing issues with your system. Having dirty or old filters can also lead to inefficient airflow.

While you may be able to replace your air filters yourself, it’s important to have an experienced technician come out to check them. This will allow them to spot potential issues and perform maintenance.

5) Cleaning The Air Ducts and Vents: It’s important to check your home’s vents to make sure that they’re working properly. Sometimes, they can get covered or shut off without you even noticing. Also, make sure that the vents are free of dirt and foreign objects that could block the flow of air.

6) Avoid Prolonged or Continuous Use: During the summer, your AC might be on for an extended period, which can cause its components to freeze. If this happens frequently, it’s time to call in the experts. Turning off the fan and letting the unit cool down for a couple of minutes will help prevent the components from freezing.

7) Check The Wired Connections: Sometimes, wires get damaged or disconnected. This can happen while your AC unit is being used outside, and it can be caused by landscaping equipment. Before you start your system, make sure that all of its wires are properly secured. Also, make sure to avoid touching any exposed wires, as they could carry shock.

8) Refrigerant Level Could Be Low: If your refrigerant level is low, it could lead to a leakage from the system. Adding more Freon will not fix the issue, and it can also harm the environment. It’s important to note that a leak can be prevented by having a trained technician inspect and repair the system.

9) Faulty Compressor and Blower: If an AC unit is too big, it could cause it to turn on and off too frequently, which could lead to issues such as the compressor and fan eventually wearing out. Having an experienced technician inspect the wires and terminals of the unit can also help prevent corrosion.


Sometimes, diagnosing a problem with your HVAC system can be simple. However, it’s important to call in the professionals if the issue is not resolved quickly or if it is complex. Doing it yourself could lead to costly repairs and voiding your warranties. Most problems with heat pumps, air conditioning units, and furnaces require extensive training.
