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.

Fantastic team. Completed the job as per the specifications and in under 3 hours. Highly recommended Twintech.

During the summer, I previously hired TwinTech to replace my air conditioner when it failed. They did an excellent job so when I decided to proactively replace the furnace I contacted them. The furnace I had was 22 years old and showed signs of internal leakage. It still worked but rather than wait to have it fail in cold weather, I decided to purchase a higher efficiency model before it failed and take advantage of energy efficiency rebates. TwinTech offered very useful advice on the make and model of furnace to choose including high efficiency and variable speed motor. The price was reasonable, TwinTech arrived at the allotted time, installed the new furnace (including some re-routing of exhaust lines since the existing ones were too close to other vents), removed the old furnace, tested the installation and cleaned everything up. Overall, it was a good experience, they did a great job and the new furnace is working well.

Greg came over at 9:30pm to rescue my daughter and I from a horrible experience with Enercare that evening. He was professional. Kind. And got us what we needed quickly and at an afford price. I would 100% recommend calling on Greg and his team for any of your heating and cooling needs in the future!!

Installed a great hot water heater when our old one failed. When my furnace died during cold weather they showed up quickly and my house was warm before my wife got home. :)

I dont usually right reviews but when you receive service like this I felt it was a must. Honest and fair. I Have 4 children and on Xmas eve my furnace stopped working and a gentleman came out and got me up and running so at least we would have heat for the holidays. As promised he would replace my furnace early in the new year. The job was completed on time, great price for quality furnace and extremely clean and professional job. Would have never known anyone was in the house. Not a spec of dust or mess from lugging out an old rusty furnace. If you have any ac or heating concerns twintech is your only option. I was royally impressed with and Im sure you will be too.

Class Act ! These guys were professional right from the quote stage through to installation. They know their stuff and took their time to help educate me. They take pride in their work and it shows. I would recommend TwinTech Heating and Cooling to anyone. Keep up the great work !!!

This Company is terrific. No high pressure sales and they deliver exactly what they promise to deliver. The new furnace is great and we now get consistent temperatures throughout the house. The installers were great and very efficient and completed the work on schedule on the promised day. Everyone representing this company was very aware of their presence in our house and worked diligently to keep our home as uninterrupted and as clean as was humanly possible. We did not need to go around the house to clean up after they left, what a nice surprise. We have had follow up by the company to ensure everything is to our satisfaction. How unusual in today's environment. The impression left by Twintech is that they care about us and our home. This is so refreshing in today's high tech world. Out thanks go out to Dave in sales and G, G, and P (the installers).

Dec 23, 2018
The entire process was prompt and professional, from the initial quote to the installation of the new furnace. The team installed the new furnace and removed the old one in approx. 4 hrs. The guys were very knowledgeable and gave me lots of information. I have used Twintech before for a new A/C installation and new I was in good hands.

The overall experience dealing with this company was great from start to finish when getting a new furnace and ac this year. Everything was clearly explained to us during our consultation with Dave and there were no surprises with added costs. The work was done as expected and their response time to inquiries were very timely generally within a few hours or less. They are all very professional and was a pleasure to do business with them. Highly recommend to anyone looking for honest quality professional service.
