Here’s Why Your Air Conditioner Can’t Keep Up on Hot Days


Posted by Spencer | July 10, 2023 | Reading Time:

During the hottest months of the year, your air conditioning system is especially important. However, even with a functioning HVAC system, you might notice that your air conditioner can't keep up on hot days.

There are many reasons your AC could be struggling to cool your home during a heat wave. Regardless, the best solution is to call for a top-rated, professional AC tune-up in Phoenix, AZ, from Rainforest Plumbing & Air. Our professionals can optimize your air conditioner for the summer heat.

1. Suddenly Increased Demand

When a sudden heat wave hits Phoenix, everyone knows that temperatures can rise to unbearable levels. While you may want to crank up the cool air, your air conditioner may not be ready to function at these high levels. It might be difficult for your system to achieve your desired temperature during intense heat since it will have to work much harder to achieve the same result.

2. Insufficient Window Coverings

Window coverings do more for your home than add a decorative element. Windows are one of the main influences on your home’s indoor temperature and energy efficiency. Without blinds or curtains to curtail the effects of the summer sun, you might notice your air conditioner can't keep up on hot days.

3. Incorrect Thermostat Settings

Thermostat settings help your unit identify when it has reached your desired temperature. However, cranking it down too far will overwork it and allow more heat into your property. Most technicians recommend keeping your thermostat set to 78ºF to optimize efficiency on hot days.

4. Inappropriate Sized Unit for Your Property

If your air conditioner is too small for your home, it doesn’t matter what tricks you try. An inadequately sized unit will be unable to cool your property, especially on very hot days.

5. High Indoor Humidity Levels

Excess moisture in your home’s air can make it feel much hotter within your property. Leaks, standing water, or other additional moisture sources will make the air feel thick and force your air conditioner to work harder. Call professionals to remove this water or use dehumidifiers to see if it resolves your air conditioner’s issues.

6. Mechanical Issues

Any mechanical issues with your air conditioner will decrease its efficiency and ability to cool your property. Problems with your blower motor, compressor unit, or condenser unit could not only cause temperatures to rise within your home but could also lead to an expensive HVAC breakdown. Call professionals to inspect your system and resolve these problems.

7. Refrigerant Leak

Leaking refrigerant can get into your air conditioner and cause many issues. From frosting to issues with your coils, leaking refrigerant can lead to expensive repairs. Furthermore, low refrigerant levels mean that your air conditioner won't be able to remove hot air as easily.

8. Dirty Evaporator or Condenser Coils

Dirty coils can create a range of issues for your air conditioner. As dirt and debris gather on your coils, their ability to cool the air flowing through your system decreases. Professionals will need to clean your coils before you can expect your air conditioner to function optimally.

9. Dirty Air Filters

Dirt and debris gathering within your system can also adversely affect your air filters. Neglecting to change your air filters for too long can cause issues for your air conditioner and limits its ability to cool your home. Changing your air filters could help address why your air conditioner can't keep up on hot days.

10. Inadequate Insulation

Your home’s insulation in walls and attic spaces plays a major role in your indoor temperatures. Inadequate insulation in the form of cracks or spaces between walls, windows, and doors can allow more heat to enter your home and impact your air quality and temperature.
