There’s never a good time for an AC failure, but when the AC stops working during a heatwave? That’s the worst — and depending on how high the temperature climbs and how long it takes for the heat to break, it can even be dangerous. 

Why a Heatwave Can Cause System Failure 

The official definition of a heatwave is a period of abnormally hot weather that lasts for at least two days. The temperature has to rise above the historical average for the date in your area. 

The typical air conditioner can only lower the indoor temperature to about 20 degrees less than the outside temperature; trying to lower the temperature much lower can put excessive strain on the cooling system. Unfortunately, this also means that a heatwave will force the equipment to work harder, which can lead to a system breakdown.

Older or neglected air conditioners can also struggle to keep up with heatwave conditions. Regardless of why your AC stops working during a heatwave, you need to act quickly to get it running again and find ways to stay comfortable in the meantime. 

Troubleshooting an AC Failure 

When your AC stops working during a heatwave, the problem may be minor. For example, if the air conditioning puts more strain on your electrical system, it can trip a breaker switch and cut power to the unit, and all you need to do is turn it back on. 

Other quick fixes to try include:

• Confirming the thermostat is set to cool and the battery didn’t die
• Replacing the air filter, if necessary, is always strongly recommended
• Checking the outside coils for ice and allowing them to thaw if frozen. When this occurs, it’s best to call Forbes as there are likely additional underlying concerns. 

If these tricks don’t work, call an HVAC company for emergency repairs and focus on keeping cool. 

Keep Your Home Comfortable During an AC Failure 

If the air conditioner fails, prevent heat related illness by drinking plenty of water; avoid dehydrating beverages that contain caffeine or alcohol. Wear lightweight, loose-fitting clothing, avoid strenuous exercises, and soak your feet in ice water if you’re overheating. 

To keep your home cool, do the following:

• Invest in sun shades or vegetation that will reduce direct sun rays
• Close the curtains or blinds to block the heat from entering your home
• Avoid using heat-producing appliances
• Do NOT turn your AC off when you are out of town or at work. Turning the thermostat up no higher than 85 degrees will allow your home to avoid extreme heat that would otherwise overload your system when it needs to cool the space down again. 
• If your home has hard-to-cool rooms, mini split options may be an answer. 
• Complete a semi-annual HVAC maintenance to provide longevity to your system and catch issues before they arise. 

Arizona heatwaves are a constant in the forecast during our summer months. Take a few preventative steps to keep your home’s most essential systems working. Help your home find shade, set the thermostat a few degrees higher, keep the blinds closed, and avoid creating any excess heat to prevent overstressing the systems.

Above all, don’t forget your semi-annual maintenance!

If you own a Scottsdale, AZ home, you’re probably already well-equipped for the blazing hot weather that makes this one of the hottest states.

Whether it’s simply traditional air conditioners or a ductless mini-split, your cooling units keep your indoor climate from matching the outdoor 100+ degree temperatures that span May to October.

But should you also consider a unit for your hard-to-cool spaces?

Forbes Refrigeration & HVAC believes all residential rooms in constant use should feel comfortable, not only for those that reside within, but to aid your additional systems from working harder than they need to!

Below, our team explains the benefits of adding air handlers in these areas.

What Are the Benefits of Installing Mini Splits in Garages?

A garage is a place to park vehicles, store family memorabilia and likely additional refrigerators to hold hundreds (or thousands) of dollars of food, or gather family members around a pool table or outdoor theater system.

Whatever the case – garages aren’t as ventilated, leading to higher indoor temperatures and humidity.

Compact Sizing and Placement Options

Since the indoor part of mini-split systems comprises a compact evaporator unit while the condenser section rests on the grounds elsewhere, the system doesn’t take up too much of your storage space.

Moreover, choose your ductless mini-split placement depending on your layout. If most of your storage is on the floor, choose a wall or ceiling unit. Our team will be able to share options to optimize your new “cool” space by customizing your needs!

Favorable Costs and Energy Efficiency

Unfortunately, the heat adversely affects stored items, mechanics, and memorabilia, causing homeowners to believe they must choose between ruined objects or high cooling costs.

But because these systems don’t use ducts that consume 30% of cooling energy, mini splits prove more efficient. They also move heat rather than produce coolness, which burns less energy and keeps utility bills affordable.

Why Do Mini Splits Prove Beneficial in Guest Casitas?

If you’re considering mini splits for guest casitas instead, you and your guests or renters reap the following benefits:

Flexible Zoning for All

Everyone has their temperature preferences. While some may agree with the Energy Department’s 72-degree temperature suggestion, a mini-split can customize your environment, especially at different times of the day.

Because mini-split air conditioners allow you to set each air handler to a different cooling setting, you don’t have to worry about dictating your preferences. We all want to choose our own comfort level..

Noise Control for Absolute Comfort

Even with the right settings, individuals feel uncomfortable if a unit operates loudly, keeping them up at night or drowning out the TV or conversations.

Rest assured, the air handler fan also runs at low speeds, operating silently for absolute audible comfort.

Transform Rooms Outside Your Home with Optimal Cooling

Sometimes, the rooms that need some extra cooling TLC are not within your primary residence.

Whether you need to install a ductless mini split system or just a few more air handlers in your garage, home office, fitness room or guest casitas, call Forbes Refrigeration & HVAC and allow us to transform those hard to cool places into comfortable spaces!
