HVAC problems aren’t always complicated. In fact, doing some basic troubleshooting can save you from booking unnecessary HVAC service appointments. Hwew local HVAC contractor Anthony’s Cooling & Heating shares a few things you should check before booking an HVAC service appointment.
No Cooling or Heating
If your HVAC system isn’t blowing warm or cool air, check to see if the system is turned on. If turning it off and back on again doesn’t help, the circuit breaker (there should be a dedicated breaker for your HVAC system) may be tripped. Resetting it should restore power back to your HVAC system. Reset your thermostat as well. If you have a mini-split system and only the indoor unit is running, turn off the thermostat controls for one to three hours. Certain models are designed to self-reset if turned off for more than one hour. If your HVAC system still doesn’t blow air after this, call for repair services.
High Utility Bills
In addition to maintaining indoor air quality, HVAC systems also maintain indoor temperatures. This means that if something is causing heat leaks–such as insufficient insulation or leaky windows–then the HVAC system increases its output to make up for the difference. Unfortunately, this results in higher utility bills. Incorrect thermostat settings may also increase your HVAC system’s energy requirements, so make sure your thermostat isn’t set to a temperature that’s too cold (or too warm).
If your HVAC system is turning on but you’re not getting any airflow from the vents, something may be blocking them. Check the air filters and make sure they’re not clogged. Air filters need to be replaced every three months, or even sooner during periods of heavy use. Air ducts require cleaning and resealing every three to five years. Keeping the air ducts clean helps prevent leaks and maintain good indoor air quality.
HVAC System Is Constantly Running
HVAC systems are supposed to automatically switch off when they sense the room has reached the desired temperature. If it seems to be running all the time, check your thermostat settings, as ithe thermostat may be set at a temperature that’s too low for the cooling season or too high for the heating season.
