The DIY Basics and Things You Can Do Today
Not every heating and cooling hack has to be done by licensed professionals. Check out these HVAC maintenance tips and DIY methods to increase efficiency at home.
Check air filters regularly
Check the air filters for dirt and buildup. Replace them at least seasonally to improve circulation. If you have the washable filters, take them out and clean them thoroughly as often as needed.
Clean visible vents
You can clean accessible vents at home. It saves you a professional visit and enhances comfort.
Set the thermostat
In summer, the HVAC system should be set to 75 to 78°F. In winter, it will be around 66 to 72°F. Do not overwork the unit with extreme temperatures. It helps the unit last longer while offering great comfort to you.
Let the HVAC unit rest
Every machine needs a little break to reset. Avoid leaving your HVAC running all day. You can turn it off in unused rooms and alternate. It gives the motors a chance to rest to prevent overheating.
Optimizing Your Environment
Aside from a powerful device, an optimized environment is also crucial. It builds the foundation for your HVAC to achieve its full potential. On top of that, it also reduces the energy bills. On the other hand, ignoring these environmental factors may reduce the unit’s lifespan.
Attic insulation
A well-insulated attic can save you a ton on heating bills. It makes the house much warmer and reduces mold. Not only does attic insulation keep the cold away in winter. It also helps keep the house cool in summer by insulating the heat out.
Keep vent exits clear
Do not block the vent exits with furniture. Blocked exits compromise the circulation, adding pressure to the machine.
Seal cracks
Sealing cracks at home is usually a simple and low-cost task. Yet, it helps every homeowner save. If you notice drafts coming through, follow the wind and find the cracks.
Manage humidity levels
A dehumidifier can manage the humidity levels better and create an ideal working environment for heating and cooling. High humidity levels usually add an extra burden to your HVAC system. It is not designed to act as a dehumidifier.
Manage usage and activities
Help the unit with conscious care. Do not leave the windows open when you set the output to the max. It forces the unit to run continuously without ever achieving the set temperature. It can cause significant damage to the core components.
When to Call the Pros and Get Professional Maintenance
If home DIY methods do not improve performance or address existing problems, contact Astera for professional HVAC maintenance.
Unusual utility bills
Most people notice that something may be amiss when they receive high utility bills. It means at least one appliance is not working as it should. With a smart system, you can diagnose the problem instantly. Otherwise, you have to locate the culprit manually.
Odd smells and sounds
If you notice weird smells or sounds, you should disconnect the power and stop using the device. A burning smell can indicate a serious internal problem and should be addressed right away.
Inconsistent HVAC cycles
Sudden system turn-offs can indicate wiring or sensor issues. Or worse, the engine is no longer functioning properly. Inconsistent cycles reduce home comfort and should be looked into.
Uneven temperature
If you have ruled out dirty filters as the reason, uneven temperature may suggest something more serious. It will require a professional look to determine the cause and solution.
In conclusion

While professional checkups are beneficial for enhanced results, there are still many small steps you can take to save money and maximize efficiency. Follow this homeowner’s checklist to enjoy the ultimate comfort in your home.
