Is My AC Unit Overworked?
Posted On: May 31, 2024
If you're concerned that your AC unit might be overworked, there are several signs and factors you can consider to determine if it’s operating beyond its capacity or needs maintenance. Here’s a detailed guide to help you assess the situation:
Signs Your AC Unit May Be Overworked
-
Constant Running:
- If your AC unit runs continuously without cycling off, it could be a sign that it’s struggling to maintain the set temperature.
-
Inadequate Cooling:
- If your home isn’t cooling to the set temperature or if there are hot spots in certain areas, your AC might be overworked.
-
High Energy Bills:
- A sudden spike in your energy bills without a corresponding increase in usage can indicate that your AC is working harder than usual.
-
Frequent Breakdowns:
- If your AC unit requires frequent repairs or if parts are consistently wearing out, it might be overworking.
-
Strange Noises:
- Unusual sounds such as grinding, squealing, or rattling can indicate that the AC unit is under strain.
-
Ice Buildup:
- Ice on the evaporator coils or refrigerant lines can be a sign that the unit is overworking and not operating efficiently.
-
Excessive Humidity:
- An overworked AC might not dehumidify the air effectively, leading to higher indoor humidity levels.
Potential Causes of Overworking
-
Incorrect Sizing:
- An AC unit that is too small for the space it’s cooling will have to work harder to maintain the desired temperature.
-
Dirty Filters:
- Clogged filters reduce airflow, making the unit work harder to push air through the system.
-
Blocked Vents:
- Blocked or closed vents can restrict airflow and force the AC to work harder.
-
Dirty Coils:
- Dirt and debris on the evaporator or condenser coils can reduce efficiency and cause the unit to overwork.
-
Low Refrigerant Levels:
- Insufficient refrigerant can reduce cooling efficiency, causing the unit to run longer.
-
Poor Insulation:
- Homes with poor insulation lose cool air quickly, making the AC unit work harder to maintain the set temperature.
-
Thermostat Issues:
- A malfunctioning thermostat can cause the AC unit to run excessively.
Steps to Address an Overworked AC Unit
-
Regular Maintenance:
- Schedule annual maintenance to ensure the unit is clean and functioning properly.
-
Clean or Replace Filters:
- Check and replace filters regularly, typically every 1-3 months, depending on usage and filter type.
-
Inspect and Clean Coils:
- Clean the evaporator and condenser coils to improve efficiency.
-
Check Refrigerant Levels:
- Have a professional check and refill refrigerant if necessary.
-
Unblock Vents:
- Ensure all vents are open and unblocked by furniture or other objects.
-
Improve Home Insulation:
- Improve insulation in your home to reduce the workload on your AC unit.
-
Upgrade Thermostat:
- Consider upgrading to a programmable or smart thermostat for better control over cooling cycles.
Professional Help
If after these checks and adjustments your AC unit still seems overworked, it’s advisable to consult a professional HVAC technician. They can perform a thorough inspection, identify any underlying issues, and provide solutions to prevent your AC unit from overworking.

We couldnt have been more impressed with Twintech - from our first service call with Mitch who took the time to thoroughly diagnose the issue with our furnace, to Dave who proposed a well thought out solution to meet our needs and finally Greg and team who acted quickly to install given we had no heat.
We did our due diligence by soliciting quotes from alternate providers and were shocked and disappointed by the aggressive and manipulative tactics used.
Twintech was honest in their approach, detailed in their product knowledge, reasonably priced, diligent in their follow-up and valued our business.
Well done Twintech! You made this a positive experience for us and our new furnace works beautifully!

We recently purchased an Amana high efficiency furnace and humdifier through Twintech. The work was completed very professionally and the quality of the workmanship was high. There was some additional sheet metal work required to complete the installation, which they were able to complete themselves. Overall I am very pleased with the work and would highly recommend Twintech for a furnace replacement.

We would highly recommend them to whoever needed a recommendation

The blower on our furnace stopped working leaving us with a cold house. Dave from TwinTech responded immediately to our HomeStars service request. From beginning to end Dave was nothing but helpful, friendly and professional, he did a great job of walking us through the quote and scope of work.
The replacement of the furnace went smoothly. The Guys did a great job, everyone was very friendly and polite. There were no hiccups, or unexpected costs. The only surprise was they left the work area cleaner than it was before they started.
Was a great experience with the whole TwinTech team. Its been a couple of months since the new furnace has been installed and its working great!

I heard about TwinTech when researching new furnaces at furnaceprices.ca. After contacting them about my broken down furnace, Dave came to my house the next day to assess my situation and requirements for a new furnace. He recommended one that had stainless steel heat exchangers which sold me since my previous furnace had issues with a rusted secondary heat exchanger that had to be replaced. Dave also set me up with an appointment with an energy audit company so that I could take advantage of a rebate to help improve the energy efficiency of my home and get some money back. A few days later, Greg, Grant, and Mitch came to install the new furnace and remove the old one. When delivering and removing the furnaces, they were very careful not to damage my floors and walls, and even laid out red carpeting to protect the floors. They were very friendly and professional. The installation was completed in the time they said it would take and they cleaned up their work areas. Within a week, Dave called to follow-up to see how everything was going. I have already recommended them to several friends and family members who may need new furnaces soon.

Twintech did a great job, from Dave the Sales Rep to the Office staff and The Professional Technicians who did the installation. They were professional, courteous, knowledgable and informative. From beginning to follow up we were completely satisfied with everything. Thanks Again. Sincerely The Laytons

Great product, great service, great follow-up. The Twintech Heating and Cooling arranged removal of my existing oil tank and they installed the new gas furnace Amana (made in USA). I am very happy with the final result and support I received throughout the process. My thanks go to the entire Twintech team for their professionalism, great communication and follow-up.

We've had Twintech provide us with work in the past, for an inground pool heater and required rough-in for a new gas stove. More recently they provided the same friendly, professional, timely and clean installation of our new furnace.
