Repair or Replace My HVAC? | Signs That Indicate It’s Time


Does your furnace or air conditioner need to be repaired? Or, is it time to look into a replacement system? New equipment will easily replace the poor performing HVAC unit with a more efficient, dependable system, but it must be done immediately. You should not have unexpected repair bills nor increased utility costs in the existing system, if it occurs then it’s time for a new HVAC system.

Loud or unusual noises

When you start up and shut down the heating and cooling unit it’s normal to hear the low-level sounds. But if you hear unusual noises such as grinding, grating, and whistling then it’s time to replace your HVAC. The buzzing or rattling sound indicates that your heating and cooling system may have a loose part. If you hear any uncommon noises immediately take action and call your technician to inspect the system.

Foul odors

If you get any foul odors from the HVAC system it’s an indicator of serious issues. Musty smells from your air conditioner vents, is a sign of mold or mildew growing in the ventilation ductwork. If you can sense the odor of burning metal or melting plastic it’s a sign of a serious HVAC malfunction. Just turn off your AC unit and call the experts.


Heavy drainage or leaks are the warning signs of serious issues. A drainage tube is the major element of your HVAC that draws condensation outside of your home. If the condensation drain is clogged, then it may overflow causing water damage to ceilings or walls. If there’s an issue in your refrigerant it can lead to water leaks. Refrigerants are the chemicals which control the heat and keep your home cool always. If the refrigerant doesn’t work then overheating could occur.

High energy bills

If your energy bills spike suddenly it could be an indicator that your system is working harder. If the heating and cooling system is overworked then it’s a fault i.e (less efficient HVAC system= higher utility bills). Don’t overuse your cooling system, if it works constantly then it leads to costly repairs in the future. Call a professional to evaluate the system, if they suggest replacing it as much fast as possible.

Humidity in the home

An air conditioning system should keep moisture levels under control. If the interior space of your home is just as humid as the weather outdoors,then it needs a recalibration. If the HVAC systems fail to pull humidity out of your home then replace it. 

Poor air flow

If the airflow from the AC return vents are barely pushing out cool air, then it’s a sign of a problem. Poor air flow may be due to a broken motor, blower fan, or an even more serious problem. If your HVAC is not performing well, then the utility bills will spike.

Frequent repair bills

If you’re frequently spending money to repair an aged HVAC unit, then a new more energy-efficient system will be the best option. Contact the experts to evaluate the condition of your system, by the way, they will guide you in the most efficient heating and cooling system for your home.
