HVAC General Maintenance Tips
Posted On: March 25, 2025
Here’s a handy list of HVAC general maintenance tips to keep your system running smoothly and efficiently all year long:
1. Replace or Clean Air Filters Regularly
-
Frequency: Every 1-3 months, depending on usage and filter type.
-
Why: Dirty filters restrict airflow, making your system work harder — leading to higher energy bills and potential damage.
2. Keep Vents and Registers Clean
-
Check: Ensure vents are open and unblocked by furniture or curtains.
-
Clean: Use a vacuum to remove dust and debris from registers for better airflow.
3. Check Your Thermostat
-
Upgrade: Consider a programmable or smart thermostat for better control and energy savings.
-
Test: Make sure the thermostat is reading the temperature accurately.
4. Clear the Condensate Drain Line
-
Why: Clogs can cause water leaks and humidity issues.
-
How: Flush the line with a mixture of vinegar and water every few months.
5. Inspect and Clean the Outdoor Unit (Condenser)
-
Remove Debris: Keep leaves, dirt, and branches away from the unit.
-
Clean Coils: Gently hose down the coils to improve heat exchange efficiency.
6. Inspect Ductwork for Leaks
-
Signs: Higher energy bills, uneven temperatures, or visible dust buildup.
-
Solution: Seal small leaks with duct tape or mastic sealant. For larger issues, call a professional.
7. Check Refrigerant Levels (For AC Units)
-
Why: Low refrigerant can reduce cooling efficiency and damage the compressor.
-
Pro Tip: Only a licensed HVAC technician should handle refrigerant checks and recharges.
8. Lubricate Moving Parts
-
Components: Motors, fans, and bearings may need periodic lubrication to reduce friction and wear.
-
Check: Your owner’s manual for guidance on lubrication points.
9. Test Your System Seasonally
-
Spring: Test cooling mode before summer hits.
-
Fall: Test heating mode before winter.
-
Listen: Unusual noises like banging, hissing, or grinding may signal a problem.
10. Schedule Professional Maintenance
-
Frequency: Ideally twice a year — once for cooling (spring) and once for heating (fall).
-
Why: A pro can inspect electrical connections, test system performance, and spot early signs of trouble.

I left a live chat message on their website that my air conditioning was not working. Within 1hr a representative called me to discuss my options.
The next day he came to the house to review my needs and give me a price for a new system. Price quoted was less than I expected and the installation was completed the following day. I found their salesman and the installers very knowledgeable and easy to deal with. All my questions were answered. Everything was properly explained in regards to what unit was needed and why, along with instruction where needed for use.
The installers made sure everything was working properly before they left.

This is to thank Twintech Heating and Cooling for their exceptional and timely service. Mitch, their technician was very courteous and generous with his time right from his first meeting with us. He not only took the time to check everything but also educated us on why we needed what he recommended. Greg and Mitch graciously accommodated us on our requested day and time for job to be done. They were both very courteous and responsive to our needs and special requests especially in a tight spot. The job was finished neatly and on time. Thank you Twintech for your great service !

Our furnace was rattling, as soon as we put our air conditioner on this past week. We had researched looking for a company that was Registered with Better Business Bureau, and this company TwinTech, had A+ Rating. Scott, was immediately helpful via text/phone and sent his technician as soon as he was able...Mitchell/technician provided great professional service. Thank you TwinTech.

I contacted various companies when looking to install a new furnace and I found Twintech to be transparent with their communication and approach. They had options to suit my various requirements and the price vs quality was very good. The after installation communication was also very good and they answered all queries I had.

My furnace broke down last month. The team was quick to respond, courteous, professional and mindful of COVID-19 concerns. I highly recommend them if you are considering replacing or servicing your HVAC equipment.
