Air Conditioner Maintenance Checklist

Maintaining your air conditioner is essential for ensuring it operates efficiently and has a long lifespan.


Here's a comprehensive maintenance checklist for your air conditioner:


Monthly Maintenance.


Check Thermostat Settings Ensure the thermostat settings are accurate and set to a comfortable temperature when you’re home.


Consider programmable thermostats for better energy management.


Inspect and Clean Air Filters Check air filters every month, especially during peak usage times (summer and winter).


Replace or clean the filters if they are dirty.


Typically, this should be done every 1-3 months.


Seasonal Maintenance (Spring and Fall).


Clean Evaporator and Condenser Coils Inspect and clean the coils to ensure they are free from dust and debris, which can reduce efficiency.


Clean around the coils to improve airflow.


Inspect and Clean the Drain Line Ensure the drain line is clear of blockages and algae.


Flush with a mixture of bleach and water to keep it clear.


Check Refrigerant Levels Check the refrigerant level and top it up if necessary.


Low levels can indicate a leak that should be repaired.


Examine Ductwork Inspect ductwork for any signs of leaks or damage.


Seal any leaks with appropriate duct tape or sealant to improve efficiency.


Annual Maintenance.


Professional Tune-Up Schedule an annual professional maintenance service to inspect and tune up your system.


Inspect and Clean Fan Blades and Motor Clean the fan blades to remove any dirt and debris.


Lubricate the motor if necessary to ensure smooth operation.


Inspect Electrical Connections Check all electrical connections and tighten any loose ones.


Inspect the wiring for any signs of wear or damage.


Check and Clean Blower Components Clean the blower components to ensure efficient airflow.


Inspect the blower belt for any signs of wear and replace if necessary.


Inspect Insulation Check the insulation on refrigerant lines leading to the house.


Replace if worn or damaged.


Additional Tips.


Clear Debris from Outdoor Unit Keep the area around the outdoor unit clear of leaves, grass, and other debris to ensure proper airflow.


Trim back any vegetation that may obstruct airflow to the unit.


Test the System Run the system for a short period to ensure it’s cooling or heating properly.


Listen for any unusual noises or vibrations that could indicate a problem.


Check for Air Leaks Inspect windows and doors for air leaks and seal them to improve efficiency.


Ensure that there are no obstructions blocking the vents inside the home.


Regular maintenance of your air conditioner will not only improve its efficiency but also extend its lifespan, providing you with reliable comfort throughout the year.

by Private User on Twintech Heating and Cooling

It was a refreshing experience interacting with the Twintech team. From Bob, the sales consultant, who articulated in layman's terms all the options available and reasons for making any selection. This was done without the prevailing pressure tactics so commonplace today.

Before proceeding Mitch, the technician, at our request conducted a service check on our 30 yr old furnace. His report was positive indicating no urgency to replace it. Again no pressure tactics.

Three days after first meeting with Bob, the installation team of Greg and
Spencer completed the installation within the planned time frame.

A very professional, courteous and transparent team which delivered on their promise. I highly recommend Twintech.

by Private User on Twintech Heating and Cooling

Initial contact with sales resulted in an immediate response, which led to a timely installation. Both sales and installers were all very professional. I have no hesitation in recommending TWINTECH.

by Private User on Twintech Heating and Cooling

I had a great experience with TwinTech. The company offered a reasonable quote, and performed a quick and clean installation. The installer Greg was experienced, professional and courteous. He explained the services he performed and gave recommendations on maintain the new furnace.

The salesman Bob was honest
and professional and educated me on how to achieve optimal performance.

All communication from them was quick and they came the following day. I was pleased with the service and would recommend them.

by Lousan, Ajax on Twintech Heating and Cooling

From quote, to installation, to follow up, Twintech provided excellent service. I would highly recommended their services.

by John, Pickering on Twintech Heating and Cooling

I had a really great experience with these guys. The salesman Bob was clearly very knowledgeable about everything to do with heating and cooling a home, spent a lot of time with us going over the details of the job, never rushed us and came back after the install to make sure we were happy. The installation crew was excellent, they covered the floors all the way from outside down to the basement furnace room, kept the place clean, got the work done on time and we’re very friendly. I’ve got 15 years in the contracting/ construction industry and these guys are one of the most professional company’s I’ve dealt with. Great company!

by Debra Robertson on Twintech Heating and Cooling

Had great service and clean-up was good. Was happy with my salesman. They were very friendly and helpful. I needed a new furnace as our was over 20 years old. The furnace and air-conditioner work great and they are very quiet. I am very pleased with the service and product I received.

Reviews for Twintech were good, and they did not disappoint. After an initial visit to discuss the suitable AC unit for replacement, an installation date was available in just a couple of days, and everything was installed without a hitch. Highly recommended

by Private User on Twintech Heating and Cooling

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.

by Darren, Pickering on Twintech Heating and Cooling

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.

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!
