Because of Arizona’s excessive heat and sometimes high humidity in the summer months through mid-fall, efficient cooling units are especially important. So, what can happen when two types of vital air conditioning fins located on the outdoor AC unit aren’t working properly to keep your home cool? Let’s explore what AC fins do and what can go wrong with these vital components.

What are fins?

The outdoor AC unit actually has two types of fins doing almost the same type of work to help air flow smoothly in and out of an air conditioner. Evaporator coils remove heat from the air passing through using refrigerant running through copper tubing. This thermal energy exchange is assisted by the evaporator metal fins where the air is cooled down and moved along from the outside AC unit to indoor rooms via ducts and vents.

The second type of fins, called compressor fins, can be found near the AC compressor on the outdoor unit which looks like a metal grill. The AC compressor fins help to move heat away from the air conditioner, so the heat clears out quickly. Clean fins keep the air flowing and result in efficient cooling.

Fins Issues

When the fins don’t work properly, your air conditioner will eventually malfunction. The two primary types of issues with fins are:
Bent Fins
Fins can be prone to bending over time. When the fins become bent, air flow is immediately restricted to the AC unit. The resulting reduction in efficiency levels means your AC has to work harder to create cooler air. This can eventually cause the air conditioner to wear out faster due to overuse.

Dirt & Dust

Dirt and dust particles floating in the air are circulated along the exterior portions of the evaporator and compressor and eventually can cause an excessive buildup of these particulates. This buildup can eventually cause airflow to drop due to clogged fins. Higher electricity bills can be one of the first signs of this issue. Monsoon thunderstorms preceded by a haboob (dust storm) can exacerbate this issue.

It may be the official end of summer, but your AC is likely continuing to work hard to maintain the ideal indoor temperature. With your system still running, there’s bound to be an occasional, unusual sound or two. While not all odd noises from your HVAC are reason for concern, some are. We’ve compiled a list of four sounds to be aware of for homeowners in the Valley of the Sun.

Humming

All HVAC systems make humming sounds, but if the hum is increasing in volume, it may be an indicator that your capacitor is failing. The capacitor is the component of your AC unit that turns the motor on and off. If that hum is accompanied by delays in your unit turning on or random shut offs, it’s time to call your technician for a diagnosis.

Continuous Whirling

If a loud whirling sound is continuous while the AC is running, there could be multiple causes. It may be that the AC unit that’s installed is actually too large for your home. Damaged air ducts inside your house can also produce this type of sound. Dirty condenser fins and even an air conditioning unit that’s past its lifespan can make those irritating noises. To find out the actual cause, don’t delay and call your technician.

Squealing

When an air conditioning compressor is damaged, it can make an annoyingly high-pitched sound. This may be the most bothersome of all AC noises. The compressor is known as the “heart” of the AC unit, and it’s the component keeping your house cool during hot weather. The compressor is busy pumping refrigerant through the unit. When the compressor is broken, you’ll know it not only by the squeals, but also because the air indoors will not be cold. Best to shut off power to the AC unit and immediately call your technicians at Cool Blew for help.

Clunking

A loud, clunking sound can be an indication that a motor needs lubrication. When the AC unit continues to run without fixing this problem, you may start to hear a grinding noise. Even though DIY videos show how to lubricate a motor, it’s a job best left to the professionals.

Contact Cool Blew

Ignoring noises can turn minor issues into expensive repairs. The sooner the unusual sound is identified, and the problem resolved, the better it will be for the performance of your AC unit. Our talented team of technicians at Cool Blew are only a call away. Schedule an appointment today – 623-872-2900.

Labor Day was declared a national holiday in 1894 and is celebrated on the first Monday in September. It’s America’s annual celebration of our workers and their achievements and contributions. It’s also the symbolic end of summer and a good time to think about your AC unit. Here’s a helpful Labor Day weekend AC checklist of items before you start your holiday.

Program the Thermostat

A programmable thermostat is the simplest way to keep your home cool and comfortable. Whether you’re planning on going away on vacation or staying at home, you can save money by programming the thermostat. Set the thermostat up to 10 degrees higher if you’re going to be away from home for more than four hours. It’s your cruise control to monitor indoor conditions and keep your home at a consistent temperature until you return. Of course, if you have pets, temperature sensitive plants and home furnishings, keep the thermostat set at a comfortable energy saving temperature of 78 degrees.

Change the Air Filters

To help ensure your indoor air quality stays pristine and the AC runs smoothly, change out the air filters. This easy tip makes a difference not only with monthly utility bills, but also helps the entire system running at the highest efficiency levels. Keep in mind that when an air conditioning air filter is clogged by an overload of dust, dirt, and debris from Arizona’s monsoon thunderstorms and haboobs, the airflow inside your home is obstructed. A dirty air filter uses up to 15% more energy than a clean filter. Eventually the dirty air will flow back inside the AC unit and clog the evaporator and condenser coils helping to keep your house cool.

Tune Up

Scheduling an HVAC tune up now can help reduce the chances of a system breakdown so that you can have a hassle-free holiday weekend. HVAC systems are very complex with many moving parts. Our HVAC professionals will test your HVAC system to make certain it’s running efficiently, lubricate any moving parts, clean the system, make needed repairs, and perform a safety inspection. This will ensure your system is running smoothly and efficiently.

During the final weeks of summer, it’s important to keep a close eye on your air conditioning unit. Between days with temperatures over 110 degrees or powerful monsoon thunderstorms hitting the Valley of the Sun, your AC unit can struggle to keep your house cool. There are a number of problems that can occur warranting immediate professional attention. Here are some issues to watch out for:

Filter Failure

High on the list of issues resulting in AC repairs is from a clogged air filter. The AC unit needs the filter for its air handler. The Sonoran Desert offers the perfect conditions for dust, dirt, pollen, debris, and other contaminants to clog the unit. A clean filter keeps particulates from entering the AC unit and your home’s air ducts. It’s better to check and change the AC air filter at least monthly during Arizona’s monsoon season to help your unit operate efficiently all summer long. Fresh air filters will extend the lifespan of your HVAC system and decrease the chances of expensive repairs from damaged parts.

AC Freeze

There are a number of issues that can cause the AC to freeze up or stop working. The AC unit can shut down from a broken thermostat or a thermostat with improper settings. A fuse may have blown causing the circuit breaker to trip. The evaporator coils can freeze due to a damaged air handler fan, a clogged air filter, or a refrigerant leak. This is the time to call your local trustworthy Cool Blew technicians for immediate help.

Capacitor Down

AC units begin working earlier in the day and staying on longer in the evenings during Arizona’s brutal summers. The AC capacitor prevents the fan motor from continuously spinning at peak speed by turning off its charge. Similar to a storage battery, the capacitor turns on and off hundreds of times a day and can eventually wear out. Your highly trained technicians at Cool Blew know how to easily diagnose and fix this issue.

Hot Air

Is your AC unit only blowing out warm air from the vents? This can be the result of a malfunctioning thermostat, debris blocking the outside AC unit, low refrigerant levels, or the air filter is clogged.

Clogged Drain

Seeing water backing up near the AC unit drain? This can be a sign of a clogged drain. You’ll want to call for help before the backed-up water damages your home or AC unit components.

Help is on the Way

Your experts at Cool Blew are available 24/7/365 to get your AC unit back up and running at full speed. Call us today at 623-872-2900. We’ll make your home cool and comfortable again.

This summer has been a whopper when it comes to heat. If you’re like many homeowners, you’ve probably had a few “heated” conversations (no pun intended) about the best setting for your home’s thermostat.

Budget-focused friends may recommend a setting over 80 degrees while comfort-seeking family members might prefer a temperature in the low 70s. At the end of the day, it all comes down to what feels most comfortable for you and your family—and what works for your budget. The reality is you may just have to program your thermostat for different temperature preferences and varied schedules to make everyone happy. Let’s take a further look at some of the factors to keep in mind when you’re setting the thermostat to keep indoor temperatures in a comfortable range.

Ideal Temperature Settings for Energy Savings

The Department of Energy conducted extensive research and determined that the best setting is at 78 degrees even during the heat of summer. When the heat index is rising because of excessive temperatures and high humidity, you may be wondering if your goal is to set the thermostat at 78 degrees to limit monthly energy costs? What you want to avoid is setting your thermostat at a colder setting than normal before you arrive back home or wake up in the morning according to this study. The house will not cool down any quicker and it can result in the AC running longer than necessary costing you even more money.

A study conducted by the American Society of Heating, Refrigerating, and Air Conditioning Engineers showed the preferred temperature range for home occupants dressed in summer clothing is between 73 degrees and 79 degrees. You can do some testing with your family by slowly lowering the thermostat by one degree until the most comfortable thermostat setting is found.

Energy Star has published guidelines for optimal air conditioning settings. Energy Star agrees with a setting no lower than 78 degrees when you’re at home, raising the temperature to 82 degrees when asleep, and 85 degrees when you’re out of the house. Keep in mind that high indoor humidity levels can make you feel even hotter.

During Arizona summers, we all learn to live with brutal heat, dangerous monsoon thunderstorms, and oppressive humidity. But that doesn’t mean that you have to struggle with the heat inside your home. To combat the heat, we have a few pro tips and tricks to help keep your home cool and comfortable throughout the hot summer months.

Keep It Running

Even with higher energy bills, relentless heat outside, and a constantly running air conditioner, it may be appealing to switch off the AC to save a bit of money. Don’t risk it as it’s better to keep your AC turned on. Consistently turning the AC on and off can absolutely cost you more hard-earned dollars because the AC unit actually has to run much longer to continue lowering the temperature inside. Use the programmable thermostat, or have one installed by our technicians, to maintain various temperature settings to keep cool and save money.

Keep It Clear

One area to keep free and clear is the outdoor AC unit. If the surrounding area is blocked by bushes, grass, weeds, branches, rocks, and other debris, it will result in restricted air flow that can cause the entire AC system to operate inefficiently and potentially cause damage to system parts.

The other area to keep clear is around room vents. Blocked indoor vents from home furnishings, carpet, boxes, or furniture will reduce the amount of cool air in the room. This causes the AC unit to stay on even longer and can eventually reduce its lifespan.

Think High Efficiency

One of the best investments in long-term savings for your home is to consider upgrading your AC unit to a high-efficiency SEER2 unit. Because we live in an area requiring air conditioning up to eight or even nine months a year, a newer unit will run quieter, keep your home cooler, save you even more money on utility bills, and take full advantage of new tax credits.

The 2022 Inflation Reduction Act provides a tax credit up to $600 per item including labor for installation. This doesn’t include other savings from state tax credits and potential product rebates. You can save up to 20% to 40% of your cooling energy costs by replacing an AC unit that’s only 10 years old with a newer, more efficient model according to Energy.gov.

During the Valley of the Sun’s extreme summer heat, you need your air conditioning system to be working at its best. The 2022 monsoon thunderstorm season of record rain and damaging winds resulted in widespread damage and power outages. The 2023 monsoon season is expected to be hotter and drier.

Peoria residents know that conditions can become less than desirable during the summer months when temperatures soar, energy usage rises dramatically, and monsoon conditions begin to take shape. High winds, walls of dust, downpours of rain and plenty of lightning and thunder can be exciting to view from a distance but also potentially damaging to your house. By preparing now, you can protect your house from severe weather and its potentially damaging consequences. Here are four ways to prepare your home for our monsoon storms expected to start after mid-July.

Secure Items Outdoors

Walk around your home and take inventory of items that may damage your house or blow away. Secure items such as table umbrellas, patio furniture, garbage cans, pool items, and other objects which may cause damage during a storm.

Protect Your Outdoor AC Unit

Falling trees, blowing branches, and flying debris are some of the greatest risks during a monsoon storm to your AC unit. One of the easiest ways to protect the unit is to trim back all nearby trees, bushes, and other landscaping. These can all be hazards that can both damage the air conditioning unit and potentially blow debris inside the unit or into your windows.

Install Surge Protectors

During monsoon thunderstorm season, severe storms may result in power outages or a direct hit from a lightning strike. If lightning hits your home, you could experience an electrical surge which can damage your electronic devices, appliances, and electrical systems including your AC system. Purchasing a whole house surge protector, you can protect your HVAC system, as well as all the important electrical equipment that you rely on.

Schedule AC Servicing

At Cool Blew, we recommend Peoria residents have their HVAC system serviced twice-yearly. If you haven’t already had maintenance this year, now is an ideal time to ensure your system is running efficiently and effectively. By scheduling AC system maintenance, you’ll be able to better manage summer energy bills, correct small HVAC system issues before they become costly repairs, and prevent breakdowns before they happen.
