Why Your AC Might Be Forming Ice in the Summertime


Phoenix metro summers are legendary for their relentless heat. But what happens when your air conditioner freezes up? This icy situation can occur for several reasons unique to Arizona’s scorching climate. Here’s why your AC might be forming ice and how to prevent these frosty meltdowns.

The Culprit: Restricted Airflow

Imagine your AC unit as a hardworking athlete. Just like any athlete needs oxygen to perform, your AC needs proper airflow to function efficiently. The most common reason for ice buildup is restricted airflow across the evaporator coils. The evaporator coil is responsible for absorbing heat from the indoor air. Restricted airflow can be caused by several factors:

  • Clogged Air Filter: Arizona’s dusty climate is notorious for clogging air filters with dust, pollen, and debris. A clogged filter reduces airflow causing the evaporator coils to become excessively cold. This leads to moisture in the air freezing on the coils, creating an icy buildup.
  • Dirty Ducts: Over time, dust and debris can accumulate within your air ducts. This buildup restricts airflow throughout your system, mimicking the effect of a clogged filter.
  • Blocked Vents: Furniture or objects placed too close to vents can restrict airflow into the system. This results in your AC unit having to work overtime to help air circulate throughout your home.
  • Malfunctioning Blower Fan: The blower fan is responsible for circulating air across the evaporator coils. A malfunctioning fan won’t provide adequate airflow, leading to potential ice formation.

Preventing the Icy Apocalypse

Here’s how to avoid these frosty situations and keep your AC running smoothly all summer long:

  • Change your air filter regularly: Check and replace your air filter monthly during Arizona’s monsoon season and every two to three months during other times.
  • Schedule regular AC maintenance: Twice yearly maintenance by a local qualified technician can identify potential problems like dirty coils or failing components before they cause ice buildup.
  • Invest in a programmable thermostat: Program your thermostat to adjust temperatures automatically when you’re away or sleeping. This reduces unnecessary strain on your AC system.

What You Need to Know about Your HVAC Air Ducts

If you live in Arizona, you know the summer heat is no joke. Temperatures routinely soar above 100°F, making air conditioning an absolute necessity rather than a luxury. But did you know that damaged or outdated HVAC ductwork could be forcing your home’s AC to work harder than it needs to? This increased strain can not only lead to higher energy bills; it can also shorten the lifespan of your HVAC system. The good news is, there are simple steps you can take to improve ductwork efficiency and lower those sky-high cooling costs.

Ductwork Leaks

The biggest issue with leaky, damaged, or aging ductwork is that it causes cooled air to escape before it can circulate through your home. According to Energy.gov, homes with ductwork leaks can lose up to 30% of the air moving through the system. Those leaks force your AC to run longer cycles to achieve the desired temperature, consuming more energy.

Hot Air and Dust

Improperly sealed ducts also create opportunities for hot attic air and dust to infiltrate the system. When that super-heated air seeps in, it makes the AC work even harder to cool your home’s air to the thermostat setting. The dust that comes in can also clog components like the air filter, further reducing efficiency.

Professional Inspection

So, what can you do to prevent duct leaks from driving up your electricity bills? First, have your local HVAC professionals inspect your ductwork to identify any leaks, disconnections, or other damage. They can then properly seal any openings using mastic sealant or metal tape. Insulating exposed ducts is another way to minimize cooled air loss and improve efficiency.
Another smart move is to ensure your ducts are the correct size for your HVAC system. Improperly sized ducts can restrict airflow, causing your system to underperform. During a duct replacement, your local contractor can calculate and install the ideal duct sizing for your home’s cooling needs.

Breathing Easy in the Desert


Phoenix metro might boast year-round sunshine, but when winter lingers, indoor air quality often takes a hit. Stagnant air, high ozone levels, blooming flowers and trees, and even everyday activities can contribute to a cocktail of pollutants that irritate lungs and impact overall health. Let’s explore the top culprits threatening your home’s air quality during late winter.

1. Dust, Pollen, and the Dreaded Dust Storm:

As winter winds pick up, they can whip up dust and pollen, creating a potent respiratory irritant. Closing windows and doors might seem your logical choice, but it traps existing pollutants inside. Investing in an air purifier with a HEPA filter can trap these airborne particles, significantly improving indoor air quality.

2. Volatile Organic Compounds (VOCs):

These chemicals, emitted from household products like paints, cleaning solutions, and personal care items, can build up indoors, especially with closed windows. You’ll want to opt for low-VOC alternatives whenever possible, ensure proper ventilation during and after product use, and properly store strong-smelling products outside if possible.

3. Mold and Mildew:

Winter months with limited ventilation and potential moisture leaks can create a breeding ground for mold and mildew. These microscopic organisms can trigger allergies and respiratory problems. You’ll want to inspect for signs of moisture intrusion, address leaks promptly with your trustworthy local HVAC specialists, and use dehumidifiers to control humidity levels below 55%.

4. Pet Dander and Fur:

While your furry friends bring love and joy, their dander and fur can exacerbate allergies and asthma. Regular grooming, frequent vacuuming, and dedicated pet-free zones can minimize airborne pet allergens. You may want to consider buying air purifiers with HEPA filters specifically designed for pet dander.

5. Carbon Monoxide (CO):

This odorless, colorless gas, a byproduct of combustion, can leak from gas appliances, fireplaces, and even portable generators. Install CO detectors in your home and ensure proper maintenance of all combustion appliances. Regularly testing these detectors is crucial for early detection and prevention of CO poisoning.

Six Ways to Improve Indoor Air Quality During Monsoon Season

Summertime brings particular air quality issues for Arizona homeowners. Monsoon thunderstorm season brings extreme heat and high humidity levels which can create challenges for your HVAC system and indoor air quality. With windows and doors shut and the air conditioner on for comfort, indoor air quality can decline to unhealthy levels.

Here are six ways to maintain your home’s indoor air quality during monsoon season and beyond:

  1. Replace Air Filters

    The first line of defense to keep indoor air quality high is your AC air filter. During the summer monsoon thunderstorm season, haboobs (dust storms) can form generating huge amounts of dust and debris which can quickly overload your HVAC system. This excess dust and debris eventually get trapped in your air filters and ductwork. By getting in the habit of regularly replacing air filters, you can minimize much of the contaminants from entering your inside air. Ideally, filters should be replaced at least every 30 days during the summer months.

  2. Keep Indoor Dust Levels Down

    For family members with respiratory issues such as allergies, asthma, and COPD, summer dust storms can be very problematic. The American Lung Association recommends a regular schedule of dusting and vacuuming to help keep indoor dust levels down.

  3. Use Localized Ventilation

    Turn on range hoods and exhaust fans when cooking or showering to reduce indoor humidity levels. Using ceiling fans and portable fans can be useful to reduce heat levels in nearby rooms.

  4. Keep Out Mold and Mildew

    Fix any leaky indoor plumbing which can contribute to the growth of mold and mildew and decreased air quality. Regularly check and clean areas in your bathrooms where standing water or excess humidity may reside resulting in mold and mildew.

  5. Add Indoor Plants

    Adding more indoor plants can help clean indoor air of carbon dioxide. Plants can even reduce formaldehyde, benzene, and VOC toxins.

  6. Whole-House Air Purifier

    Your experienced air conditioning technicians at Bruce’s can provide you with an evaluation of your house’s air to let you know what particulates are circulating indoors. In some cases, a whole-house air purifier may be a wise decision to reduce your home’s air of dust mites, spores, mildew, fungus, bacteria, and other contaminants.

By incorporating these ways to improve your indoor air quality, you’ll be able to breathe a little easier during the hot months of summer. Call your professionals at Bruce’s Air Conditioning & Heating today at 480-968-5652 to schedule your appointment.
