HVAC General Maintenance Tips

Here’s a handy list of HVAC general maintenance tips to keep your system running smoothly and efficiently all year long:
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.
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.
Upgrade: Consider a programmable or smart thermostat for better control and energy savings.
Test: Make sure the thermostat is reading the temperature accurately.
Why: Clogs can cause water leaks and humidity issues.
How: Flush the line with a mixture of vinegar and water every few months.
Remove Debris: Keep leaves, dirt, and branches away from the unit.
Clean Coils: Gently hose down the coils to improve heat exchange efficiency.
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.
Why: Low refrigerant can reduce cooling efficiency and damage the compressor.
Pro Tip: Only a licensed HVAC technician should handle refrigerant checks and recharges.
Components: Motors, fans, and bearings may need periodic lubrication to reduce friction and wear.
Check: Your owner’s manual for guidance on lubrication points.
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.
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.
Very pleased with the installation of our new furnace and A/C unit. From quotation stage to the completion of the job Twintech was very professional.
Thank you for a job well done.
My old water heater quit on me. I called TwinTech. In less than 4 days, I had my new water heater installed and the old one taken away. The whole process was quick, easy, pleasant, and well done. This is the third time I've dealt with TwinTech and I've been satisfied each time.
I had them replace my furnace last year. When it came time for the air conditioner this year, I did not hesitate to call Twintech again. I will also have them perform regular maintenance on them.
We required a new HVAC replacement after running the old
system for 18 years.
Dave understood our requirements and gave us a quote that
covered all the necessary items.
Installation was fast and very tidy. Everything works as
it should. Our thanks to Greg, Mitch and others for their
excellent work. Recommend this family owned business to
anyone else, considering HVAC or other work.
I needed a new furnace and A/C to replace my 21 yr. old units, and went to the internet to view potential companies in May, I received 3 quotes,
and chose Twintech based on their salesman Dave who was very detailed and covered off everything on what Twintech was all about,
an extremely dedicated company with so many years of experience, and after reading the on line reviews I was sold on Twintech, who did not disappoint as the installation team were top notch with Greg leading,
I would highly recommend this company without any doubts, in my books they are first class all the way. Our new Amana furnace and A/C are working perfectly !
Flawless transaction. They did exactly what they promised, showed-up on time, cleaned-up, and were highly professional. Highly recommended.
Salesperson and 2 man installation team were all professional and
knew their stuff. All three were friendly and helpful, answering all
my questions. The quality of their work demonstrated their experience
and expertise in their field.
A dear late cousin of mine recommended this company and I have been happy with the service.
We are very pleased with the work done by Twintech. They were very professional from start to finish. Dave came to our home and gave us a very competitive quote for new high efficiency furnace and air conditioner. The installers were very courteous and professional. We would highly recommend them.
Great experience getting an old furnace replaced.
Sales Guy (Dave) was great - honest, responsive, and friendly.
The work itself was done quickly and we are very happy with the outcome, thank you! We recommend TwinTech!

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.
Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!
Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.
We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!
TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
