7 Signs You Need to Replace Your HVAC Unit
Summer is just around the corner and before you know it those 90 degree days will have your HVAC unit running at full blast all day long. Is your unit ready? If you’re unsure how to answer that question, here are some signs your HVAC unit may need to be replaced before those long hot summer days.
1. Frequent Repairs and/or Recharging
If your unit requires constant repairs or recharging of coolant you are likely delaying the inevitable. These issues almost always indicate the unit is at the end of its operational life. Not only is your unit near total failure, but the cost of operation could be increased up to 20%.
2. LOUD NOISES!
One of most obvious signs of an improperly functioning unit is excessively loud noise. This could mean anything from an off-balanced fan, loose ductwork, or condenser failure. These issues can sometimes be minor, but you should contact a technician for a proper inspection.
3. What’s that Smell?
Have you noticed an off or unusual smell when your HVAC unit is running? This could indicate your ductwork is loose and/or disconnected. However, if that smell is something burning it could be an indication something is seriously wrong and potentially hazardous. In the event you do sense a burnt smell, shut off your unit and contact an HVAC technician immediately.
4. Running Constantly
Be mindful of when your furnace or AC is or is not running. If you start to notice your unit is constantly running, but the exterior temperature is fairly consistent then it likely means the unit is not functioning properly. This can lead to dramatically increased costs.
5. Old HVAC Units
Older units are like a ticking time bomb, if your unit is over 15-20 years old then it is beyond its effective age suggested by the manufacturer. This unit could cease to function in the near future. Also, if your unit is over 10 years old then you are potentially wasting up to 20% in heating and cooling costs.
6. Cold/Hot Spots
Are there areas in your home which are either hotter or colder than the rest of your house? This could be an indication your HVAC unit is pushing a reduced volume of air or the ductwork in your home has become detached.
7. Heat Pumps
a. Stuck in single mode– If your heat pump only heats or only cools, it likely means you are in store for costly repairs and a new unit is recommended.
b. Icing– Ice build-up on the unit on your outdoor unit or interior lines could be a sign of a serious issue, you should contact an HVAC technician immediately.

A Hybrid heat system reacts to changing temperatures and automatically adjusts to the most efficient energy saving method available to heat or cool a home. It is a fuel-saving alternative to traditional heating and cooling systems in that it combines a furnace with a heat pump, rather than an air conditioner. A heat pump works as an air conditioner in hot weather, but can also reverse the process and heat the home when cold weather arrives.
The reduction on fossil fuels being used also reduces the systems “carbon footprint” making it a more environmentally friendly approach to heating your home. If you are looking for a way to manage your heating and cooling bills, our Hybrid Heat solutions can help.
