The southeastern United States is set for another summer of sun, fun, and relaxation. But there’s a major drawback that Southerners are all too aware of: the damned heat.  

The summer’s merciful retreat last year made AC unnecessary for several months, but that time will soon come to an end. As such, you might think your AC unit is ready to go until things cool off again in the fall. But even though your system has been resting, it might have accumulated issues in its downtime. At the very least, it might run inefficiently when you start using it again. 

Nothing will change the scorching heat over the next few months, but there are a few steps you can take now to revamp your AC unit, and that’s what we’ll dive into today. Let’s get started!

Clean or Replace Air Filters

Cold weather can still clog air filters, and dirty filters can significantly reduce your HVAC system’s efficiency by restricting airflow. The result? A harder-working system that uses more energy. Before the heat cranks up, check your filters and either clean or replace them. This should be done every 90 days (or 3 months). 

Check Refrigerant Levels

Refrigerants are chemicals that travel through your HVAC; they change from liquid to gas as they absorb and release heat. And how does this happen? Simply put, refrigerant cycles between two coil sets in the system; one of these is indoor, the other outdoor. Inside, the refrigerant absorbs heat from indoors and cools the air. The chemical then shifts to the outdoor coil to release heat, and the process begins again.

Problems arise when low refrigerant levels inefficiently cool a living space; this strains your system and can even damage it. Since this is a technical repair, your best bet is to contact a trusted technician such as Cooper Mechanical Services to ensure your refrigerant levels are where they need to be.

Test Thermostat Accuracy

A malfunctioning thermostat can cause temperature inconsistencies and unnecessary energy consumption. To test it, you’ll want to set it to a specific temperature and monitor how accurately it maintains that level. 

To begin, you’ll need tape, a paper towel or paper napkin, and a glass tube thermometer. Once you have these, place the towel or napkin against the wall near the thermostat, set the thermometer on top of it, and tape it to the wall at the same height as your thermostat. 

Leave the thermometer for 20 minutes, then compare the temperature on the thermometer and your thermostat. If the thermometer and thermostat both have the same reading, your thermostat is accurate. If the readings are more than 3 degrees different, it may be time to schedule a service call. 

Seal Ductwork

According to Energy Star, the average home loses 20 – 30% of its conditioned air due to gaps, cracks, or loose connections in the ductwork. You can seal easily accessible ducts with visible damage using foil tape or mastic sealant. Despite its name, steer clear of duct tape—it doesn’t last very long or perform as well as other options.

That said, if you doubt your agility or mechanical judgment, give us a call! We’ll get your ducts sealed in no time and keep you from getting hurt or damaging materials. 

Clear Vents & Registers

At Cooper, we’re not into parental scolding. That said, we still have to stress keeping your household clutter-free, but for different reasons than you think. Namely, clutter can cause household items to gather around AC vents and registers, impeding their output and cooling capacity.

A foolproof way to cut your unit some slack is to clear items like clothing and furniture away from your AC outlets. Doing so will lead to better air circulation and a more comfortable space.
