HVAC Do’s and Don’ts Before Summer Hits
It’s that time of year when many families are preparing for summertime fun. But it’s also a critical time to see to it that all of your home systems are ready to handle the added workload that comes with hot temperatures.
Certainly, a home’s heating, ventilation and air conditioning (HVAC) system is one mechanism that does an awful a lot of work during the summer. Here, a Service Experts specialist shares seven strategies to keep in mind when preparing your HVAC system for summer.
Do Get an HVAC Tune-Up
A twice annual HVAC tune-up can act as protection against future breakdowns. While anything can happen when a system is running a lot during extreme weather, getting your AC, furnace and other HVAC components tuned up before repair crews get busy during the sweltering summer season can certainly help you head off costly repairs down the road. Plus, it also offers a status check for how your system is currently functioning. Regular maintenance also may help keep your valuable manufacturer’s warranty effective, which aids you in case a key component fails during the warranty period.

“Tightening electrical components, cleaning condensate lines, cleaning the outdoor and indoor coils, and lubricating necessary components, it’s all part of the annual checkup we do,” said Service Experts Field Operations Manager Mike Carson. “And, we’ll change your air filters and answer any questions you may have too. It’s the best small investment any homeowner can make this time of year.”
Don’t Put Off Repairs
When a specialist advises repairs during a tune-up or if they happen unexpectedly, some homeowners think they can extend the use of the part or component for “just one more summer.” This reasoning, however, only leads to more pricey repairs later on.

“Clogged lines, dirty filters, low refrigerant (Freon), loose or broken parts, you name it, it all contributes to how efficiently your system runs. It’s always best to address problems when they arise to keep it operating to its full potential,” Carson explained.
Do Upgrade Your Thermostat
If you haven’t already done so, upgrading to a smart thermostat could decrease wear and tear on your HVAC system. Ponder this: Energy savings estimates can run from as low as 12% a year to more than 20%. Your best bet is to go with an Energy Star®-certified thermostat, Carson said, and ask an HVAC pro about how to set cooling times that match with your daily habits. In some locations, you also may be able to take advantage of reduced electricity rates during off-peak hours.
Don’t Use an Overly Restrictive Air Filter
Consistently switching out your air filter is critical; however, there are a lot of different filters to choose from. Certain types can be very restrictive, promising to catch or eliminate all viruses and contaminants. While they may successfully remove many contaminants, these highly restrictive filters might also significantly reduce airflow and potentially make your unit work harder. When you arrange your tune-up, it’s a good plan to ask the technician for a recommendation, Carson added.
Do De-Clutter and Remove Obstructions
This is not merely a recommendation about household clutter, but more about removing the airflow obstacles inside and outside of your home. First, indoors, if air vents are hindered by furniture or household items, that can restrict airflow into that room or location. That means your cooling system will be forced to run longer to get the air temperature to the level set on your thermostat.
The other location where obstructions can cause trouble is around your condenser coil outside the house. Some residents see these as an eyesore and attempt to cover them up with shrubbery or even build structures or other landscaping. Not a good idea!

“Obstructions to units and vents on the inside and outside of the home can be both an efficiency and safety concern,” Carson noted. “Covering up or blocking return air vents, where the system draws in the air inside the home is another common problem we see. These things can be like asking your system to work harder while wearing a very heavy face mask.”
Don’t Neglect Your Air Ducts
Clean air ducts are vital to the condition of your residence—and the people who are living in it. Pollen and airborne contaminants from sprays, cooking, candles, fireplaces and off-gassing items can all stay inside your air ducts and cause problems for people who have asthma and allergies.
Here are some signals your home may be ready for an air duct cleaning:
- Mold is in the home or inside the air conditioner.
- Dust comes from vents when the blower is turned on.
- A renovation that generated considerable dust has recently been done.
Do Consider a High-Efficiency HVAC Upgrade
If your HVAC equipment is close to the end of its life, replacing it with a modern, high-efficiency system before summertime is here can be better than waiting for “just one more summer.” Although that has always been the case, it’s more true now than ever before.
