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.

I had cold and hot spots all over my 70 yr old home. My furnace is quite new and Greg optimized the fan and furnace. The original installer just took it out of the box with factory settings and installed it- basically running at 50% of capacity. Greg also routed heat into my laundry room, yeah - so now I can renovate laundry room - thanks Greg. He is honest, professional and knowledgeable. I will be calling him back in the spring to optimize my AC as well.

Wonderful from beginning to end. I tend to fret and worry about home improvements but the excellent team at TwinTech put my mind as ease. They listen, they are patient and best of all ... the work they did is amazing! I chose the Goodman 80K BTU 2 stage furnace and the matching Goodman air conditioner. Greg, Grant and Poitr "Peter" arrived on time, took great care, explained everything to me and they answered all of my questions. They carefully adjusted the factory settings to optimize the furnace for my house and they also checked the duct work in the basement. Dave, the Sales Manager, came by to say "hello" and to see if I was happy. YES, I am happy with the work! The furnace is very quiet. I have it running on low just to circulate the air in the house and it's so much quieter than my old furnace. When I need new duct work for an upcoming basement renovation TwinTech will be my first choice. I highly recommend TwinTech. PS. They were even nice to my dogs.

Greg was prompt on the scheduled day of installation and the work was done well within the time estimated beforehand. Installation was neat and the equipment and scope of work was as specified in the quote. One item I must point out is that we were faced with a "No Heat" situation the day before the scheduled installation and Greg came out to address it free of charge. Not only that, but he also corrected an installation fault with our smart thermostat that was not part of the original job, again free of charge.

Greg came by to do a routine furnace checkup. He was very knowledgeable and professional, letting me know what's being checked/adjusted and giving me tips to ensure everything runs smooth. Very honest and upfront about what's working fine vs. what may need to be fixed/replaced. He didn't attempt to up sell anything that wasn't necessary. I'm glad to have finally found someone I can trust and rely on for all my HVAC needs - furnace, A/C, and hot water tank.

I'm very happy with the work that was done. Everyone from salesperson to the installers were friendly and professional. They were on time and cleaned up the job site after it was installed. They also answered all my follow up questions promptly. I wouldn't hesitate to work with them or recommend them again.

Thanks to the team at Twin Tech for a great job installing my new heat pump/ac unit. The guys were very polite and professional. When they left you would never have known they had been there except for the new Mitsubishi unit on the wall!! would highly recommend the Twin Tech team.

Very impressed with this company. They show up on time , kept my place clean and after they left it looks like they were never there. Very professional team. Those people know what they doing . Their installation was on the highest standard. They are very knowledgeable especially they're worker Peter. I strongly recommend this company to everybody. After the installation I receive the call making sure I'm satisfied with their products and their job. Bravo!!!

Greg and his brother were referred to us by a friend. They arrived when they said they would, did an exceptional job and left the place as tidy or tidier then they found it. Their professionalism is only surpassed by their kind and friendly demeanor. Even after several calls to help me with my high tech thermostat I feel that I could always call with any concern (No one responds to my texts as quickly as Greg) and have a friendly helpful response. I found out their grandfather started the company and now as a 3rd generation company, they are doing their grandfather proud. I would highly recommend Twintech over any other hvac company out there.
