6 Smart HVAC Upgrades That Pay Off by Summer

As summer approaches, ensuring your HVAC system is in top shape can make a big difference in comfort, efficiency, and energy costs. With a few simple maintenance steps, you can keep your air conditioning running smoothly during the hottest months. Here are our top 5 tips for preparing your HVAC system for summer.


1. Replace Your Air Filters


Your HVAC system relies on clean air filters to maintain proper airflow and indoor air quality. Dirty or clogged filters can reduce efficiency, forcing your system to work harder and consume more energy. Aim to replace your filters every 1-3 months, or more frequently if you have pets or allergies.

2. Inspect and Clean Your Outdoor Unit


Your outdoor condenser unit plays a crucial role in cooling your home. Over time, debris such as leaves, dirt, and pollen can accumulate around the unit, restricting airflow. Use a garden hose to rinse off dirt and ensure there is at least two feet of clearance around the unit for optimal performance.


3. Check Your Thermostat


Before summer hits, test your thermostat to ensure it’s working properly. Consider upgrading to a programmable or smart thermostat to optimize energy use. Setting your thermostat a few degrees higher when you're away can also help reduce energy consumption.

4. Clear the Condensation Drain Line


Your HVAC system’s condensation drain line helps remove excess moisture. A clogged drain line can lead to water leaks and potential mold growth. Pour a mixture of water and vinegar down the drain to keep it clear.



5. Clean the Condenser Fan and Coils


The condenser fan and coils play a key role in heat exchange. Use a soft brush or vacuum to remove dust and debris from the fan blades and coils. If you notice bent fins, a fin comb can help straighten them to improve airflow.

6. Switch to an R-32 Compatible HVAC System


If you’re thinking about replacing your air conditioner or heat pump, choosing a unit that uses R-32 refrigerant is a smart move. R-32 is a next-generation refrigerant that’s more energy efficient and has a much lower global warming potential than older refrigerants like R-410A.



Why Regular HVAC Maintenance Matters


Taking the time to prepare your HVAC system for summer offers several benefits:


  • Better Efficiency: A well-maintained system runs more efficiently, keeping your home cool while reducing energy costs.
  • Improved Air Quality: Clean filters and ducts help reduce allergens, dust, and mold.
  • Longer System Lifespan: Routine maintenance helps prevent breakdowns and extends the life of your HVAC unit.
  • Lower Utility Bills: A properly functioning system uses less energy, saving you money in the long run.
