Winter often brings changes in how your HVAC system sounds, runs, or feels. You might notice longer run times, new noises, or rooms that don’t seem to warm evenly. For many homeowners, these changes immediately raise concern that something is wrong. The reality is that HVAC systems behave differently in winter, and many changes are completely normal. Cold weather affects airflow, materials, and runtime patterns in ways that don’t occur during warmer months.

If we had a dollar for every time we heard, “It just needs more Freon”, we could retire and spend our days on a beach somewhere cooler than Houston in August.

Summer in Texas hits hard — and when your A/C decides to start blowing hot air, it hits even harder.

At Velocity Air A/C & Heating, we hear this complaint all the time, especially once temperatures reach “walking into a sauna” levels.
