Spring can have a big impact on indoor air quality, especially for homeowners running their air conditioning more often. Warmer temperatures, blooming plants, and increased humidity all play a role. Here are a few of the main ways spring affects air quality:

🌿 1. Pollen Increase

Trees, grasses, and flowers release pollen in the spring. This pollen can easily enter homes through open doors, windows, and even the HVAC system. Once inside, it can circulate through the air and trigger allergies or respiratory irritation.

💨 2. More Dust and Debris

Spring winds and outdoor activity stir up dust, dirt, and debris. When the air conditioner begins running regularly again, these particles can be pulled into the system and spread throughout the home if filters are dirty.

💧 3. Higher Humidity

Spring often brings increased moisture in the air. Higher humidity levels can create conditions where mold and mildew may grow in ductwork, drain lines, or around HVAC components.

❄️ 4. First A/C Use After Winter

When homeowners first turn on their air conditioner after winter, dust that has settled in the system may circulate through the home if the system hasn’t been serviced or the filter hasn’t been changed.

🏠 How Homeowners Can Improve Air Quality

Replace or clean HVAC air filters regularly

Schedule a spring A/C checkup

Keep vents and returns clean and unobstructed

Consider indoor air quality solutions such as air purification or UV lights

For homeowners, a spring HVAC inspection helps ensure the system is clean, running efficiently, and improving the air quality inside the home rather than circulating pollutants.

As you are aware, we will be having a major weather event starting Friday. Now is the time to prepare your a/c system. With the type of weather predicted, power outages are common. Below is information on how these outages can affect your system.

**********************

Power outages can affect air conditioners in a few important ways, both during the outage and when the power comes back on:

# # # During a power outage

* **The system shuts off immediately.** Your A/C can’t run without electricity, so cooling stops right away.
* **Indoor comfort drops.** In hot weather, indoor temperatures and humidity can rise quickly.
* **No active damage usually occurs** while the power is out, as long as the system was operating normally beforehand.

# # # When power is restored (this is the critical part)

* **Power surges can cause damage.** When electricity comes back on, voltage spikes can harm sensitive components like circuit boards, capacitors, and compressors.
* **Hard starts on the compressor.** If power cycles on and off quickly, the compressor may try to restart before pressure equalizes, which puts extra strain on it and can shorten its lifespan.
* **Tripped breakers or blown fuses.** A sudden surge can cause the system to shut down for safety, leaving the A/C not running even after power returns.
* **Thermostat issues.** Smart or digital thermostats may lose settings or need to reboot.

# # # Common symptoms after an outage

* A/C won’t turn on
* Outdoor unit runs but no cool air inside
* System keeps tripping the breaker
* Thermostat is blank or unresponsive

# # # How to protect your air conditioner

* **Install a surge protector** designed specifically for HVAC systems.
* **Turn off your thermostat** (or set it to “off”) during extended outages and wait 5–10 minutes after power returns before turning it back on.
* **Regular maintenance** helps ensure components can handle electrical stress.
* **Consider a hard-start kit** if your system is older or you experience frequent outages.

❄️ Should You Check Your Air Conditioning in Winter?

Absolutely — and here’s why.

Even though you won’t be using your A/C much during the winter, it’s still a smart idea to make sure everything is in good shape before spring hits. A winter A/C check helps:

✅ Prevent surprises when warm weather returns

When the first hot day shows up in March or April, you want your system ready to cool without problems.

✅ Spot small issues before they become expensive repairs

Belts, capacitors, refrigerant levels, and electrical components can wear down even while your system is off.

✅ Extend the life of your system

Routine checks keep your HVAC system running efficiently year-round.

✅ Keep your comfort high and energy bills low

A well-maintained system doesn’t have to work as hard — which saves money.

🔧 What McGilberry Mechanical checks during a Winter A/C Tune-Up

Inspect coils & blower components

Test electrical connections & capacitors

Check refrigerant pressures (weather permitting)

Inspect ductwork & airflow

Ensure the outdoor unit is clean and protected

Verify thermostat operation

Check drain line & pan for clogs or algae

🏡 Tip for Homeowners

If you have a service agreement with us, this check is already included! If not, winter is a great time to schedule — beat the spring rush and get peace of mind early. Call us today at 936.291.2640.

🥵 vs 🧊

Welcome to every Texas household in July:

🔁 One person turns the temp down to 68°
🔁 The other turns it back up to 74°
🔁 Nobody admits to touching it 🤷

We call it the Thermostat Wars.

(Need help settling the battle? Zoning systems and smart thermostats might just save the day!)
