Spring HVAC Maintenance Checklist

Here’s a Spring HVAC Maintenance Checklist to keep your system running efficiently as the weather warms up:


Indoor Unit Maintenance


Replace the Air Filters — Change filters to ensure better air quality and system performance (typically every 1-3 months).


Clean Vents and Registers — Dust and vacuum air vents to maintain good airflow.


Inspect the Thermostat — Ensure it’s working properly and consider upgrading to a programmable or smart thermostat for energy savings.


Check Drain Lines and Pan — Clear the condensate drain line to prevent clogs and water damage.


Test the System — Turn on the AC to ensure it cools efficiently and listen for unusual noises.


Outdoor Unit Maintenance


Clear Debris Around the Unit — Remove leaves, dirt, and branches from around the condenser.


Keep a 2-foot clearance.


Clean the Coils — Gently rinse the condenser coils with water (avoid high-pressure sprays).


Check the Refrigerant Lines — Ensure the insulation around the lines is intact.


Inspect the Fan and Blades — Look for signs of wear or damage.


Ensure the Unit is Level — A slightly tilted condenser can cause strain on the compressor.


Professional HVAC Tune-Up (Highly Recommended)


Check refrigerant levels — Low refrigerant can lead to inefficient cooling.


Inspect electrical connections — Loose or damaged wires can cause failures or hazards.


Lubricate moving parts — Prevent friction and wear on motors and belts.


Test system performance — Ensure everything runs smoothly and safely.

My old furnace had finally broken down for the last time when contacted twintech to have a new furnace installed…They were prompt, knowledgeable and very reasonably priced. They did such a great job i tell all my friends and family about this company.

by Damien McIsaac. Ajax on Twintech Heating and Cooling

To whom it may concern, I recently had TwinTech (Greg and Grant Dainty) replace my furnace and service both my gas fireplaces and air conditioning unit. They were professional, courteous and very fair in their pricing. I would gladly recommend TwinTech to anyone needing work done. I can be contacted at 905-626-XXXX.

by Blair N. - Toronto on Twintech Heating and Cooling

My Fiancé and I have relied on Twintech Heating and Cooling now for the better part of the last 10 years. In that time, Greg has installed a furnace, an air conditioner, and a heat-pump at our residence in Toronto. In each instance Greg and his team were a pleasure to deal with. They were courteous and professional throughout the whole process and the quality of their work is first rate. Our experiences have always been extremely positive and we have referred his services numerous times to our friends and family. Without hesitation, I would recommend Greg and TwinTech Heating and Cooling to anyone looking to service or replace their existing heat/AC equipment

by Ruth on Twintech Heating and Cooling

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!

by Anna Chin on Twintech Heating and Cooling

Amazing experience with TwinTech Heating & Cooling! Their team was professional, knowledgeable, and efficient from start to finish. They installed my new furnace quickly and left everything spotless. The technicians took the time to explain everything and made sure I was comfortable with the system before they left. Great customer service and fair pricing. I highly recommend them for anyone needing HVAC services!

by Connor Agnew on Twintech Heating and Cooling

Great experience all around. Bob was sharp and easy to talk to, and Greg handled the installation perfectly. Would hire them again in a heartbeat.
