HVAC Do's and Dont's Before Summer Hits
It’s that time of year when many families are preparing for summertime fun. But it’s also an important time to see to it that all of your home systems are ready to handle the additional workload that comes with rising weather.
Undoubtedly, a home’s heating, ventilation and air conditioning (HVAC) system is one item that does some hard work during the summer months. Here, a Service Experts professional shares seven do’s and don’ts to consider when preparing your air conditioner for summer.
Do Get an HVAC Tune-Up
A biannual HVAC tune-up can act as an insurance plan against future failures. While anything can happen when a system is being used quite a bit, getting your air conditioner, furnace and other HVAC components tuned up before crews get busy during the scorching summer season can undoubtedly help you ward off costly repairs down the road. Plus, it also provides a status check for how your system is currently operating. Regular maintenance also may help keep your valuable manufacturer’s warranty valid, which aids you in case a key component breaks 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 the field operations manager at Service Experts, 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 Delay Repairs
When a specialist suggests repairs during a tune-up or if they occur unexpectedly, some homeowners think they can prolong the use of the part or component for “just one more summer.” This reasoning, however, only leads to more expensive 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 said.
Do Upgrade Your Thermostat
If you haven’t already bought one, upgrading to a smart thermostat can43 reduce wear and tear on your HVAC system. Think about this: Energy savings estimates can range from as low as 12% a year to greater than 20%. Your best choice is to go with an Energy Star®-certified thermostat, Carson advised, and ask an HVAC pro about how to set cooling times that line up with your daily schedule. In some areas, you also may be able to take advantage of cheaper electricity rates during off-peak hours.
Don’t Use a Very Restrictive Air Filter
Regularly changing your air filter is crucial; however, there are a wide variety of different filters to choose from. A few of these can be very restrictive, promising to remove all viruses and contaminants. While they may effectively remove many contaminants, these highly restrictive filters might also slow airflow and potentially make your unit work harder. When you set up your tune-up, it’s a good strategy to ask the mechanic for a recommendation, Carson added.
Do De-Clutter and Eliminate Obstructions
This is not only a hint about household clutter, but more about removing the airflow obstacles inside and outside of your home. First, indoors, if air vents are obstructed by furniture or household items, that can limit airflow into that room or location. That means your air conditioner will have to run longer to get the air temperature to the temperature set on your thermostat.
The other area where obstructions can be a concern is close to your condenser coil outside the home. Some property owners see these as an eyesore and make an effort to cover them up with bushes 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 remarked. “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 Overlook Your Air Ducts
Clean air ducts are crucial to the condition of your property—and the people who are living in it. Pollen and airborne toxins from sprays, cooking, candles, fireplaces and off-gassing items can all stay inside your air ducts and cause problems for people suffering from asthma and allergies.
Here are a few signs your home is due for an air duct cleaning:
- Mold is in the home or inside the air conditioning unit.
- Dust comes from vents when the blower is turned on.
- A renovation that generated significant dust has recently been done.
Do Consider a High-Efficiency Equipment Upgrade
If your HVAC equipment is nearing the end of its life, replacing it with a modern, high-efficiency system before the hot summer weather is here can be better than waiting for “just one more summer.” Although that has always been a good idea, it’s more true today than ever before.
