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.

When most homeowners think about HVAC problems, they think about summer. The air conditioner can’t keep up. The house won’t cool down. Energy bills spike. That’s usually when the panic sets in. But here’s the truth most people don’t hear often enough: HVAC systems rarely fail suddenly. Most breakdowns don’t start during summer heat waves — they start quietly months earlier. Winter is one of the most strategic times to pay attention to your HVAC system.

The holidays are a busy season for your home — and your HVAC system feels it more than you might realize. Extra guests, more cooking, frequent door openings, and constant thermostat adjustments all put additional strain on your heating system. While everything may seem fine once the decorations come down, January is often when small HVAC issues begin to surface. January is actually one of the best times to reset your HVAC system, catch minor issues early, and start the year

Houston may not have months of winter, but when cold snaps hit, they hit fast. Temperatures can drop 30 degrees in a matter of hours. Homeowners turn on heaters that haven’t run in months. Heat pumps struggle to keep up. Gas furnaces finally cycle on after long periods of inactivity. Whether your home suddenly feels cold, your heater won’t respond, or the system is blowing cold air, this guide walks you through the exact steps Houston homeowners should take when the heat goe

Most homeowners know they should budget for home maintenance, but HVAC costs often get overlooked until something breaks. In Houston—where systems run nearly year-round—HVAC planning is less about guessing and more about preparing for predictable needs. Whether you want to avoid surprise expenses, improve your home’s comfort, or simply be proactive, having a clear HVAC plan for 2026 can save you money and stress.

If you’ve ever hosted holiday guests, you already know the truth: getting the food right is easy compared to keeping everyone comfortable. One person runs hot, another is freezing, someone opens a window, someone else closes it, and suddenly your thermostat is at the center of a family debate. In Houston, the challenge gets even more interesting. You may have a 40-degree morning followed by a 78-degree afternoon. Add a full house and you’ve got yourself a Texas-sized comfort

If you’re a Houston homeowner, you know the drill: The weather drops below 60°, social media erupts with “winter is here” memes, and you finally switch your thermostat from “cool” to “heat — just for tonight.” But then it happens. Your heater kicks on and suddenly… your entire home smells weird. Burning. Musty. Metallic. A faint electrical tang. Sometimes it’s subtle. Sometimes it’s “did something just catch on fire??”

Drafts might feel like a small nuisance — that little chill you notice when you walk past a window or sit by the back door. But those tiny leaks? They’re actually one of the biggest reasons Houston homeowners waste money on energy bills. The U.S. Dept of Energy estimates that 25–40% of heating and cooling energy loss comes from air leaks. In Houston, where AC is practically a year-round utility bill and heaters make surprise appearances during cold snaps, sealing drafts pays

Here’s the thing about Houston winters: they’re mild compared to up north, but they’re also unpredictable. One week it’s 80°, the next week you’re wondering if the pipes will freeze. That constant up-and-down has Houstonians running their HVAC systems in weird patterns — heat in the morning, AC by afternoon. It’s also when energy efficiency myths start circulating faster than the neighborhood group text about the next cold front.

Buying a home is a big deal — equal parts exciting, nerve-wracking, and financially terrifying. Between inspections, appraisals, and trying to figure out if your couch will fit in the new living room, there’s one thing you cannot afford to overlook: the HVAC system. In Houston, where air conditioning is basically a life-support system, ignoring the HVAC is like buying a car without asking if the engine works.

Fall in Houston is… unpredictable. One day it’s sweater weather, the next you’re wondering why you ever put the shorts away. We get 50° mornings and 85° afternoons, sometimes in the same 24 hours. And while that’s mildly amusing when you’re trying to pick an outfit, it’s not funny when your HVAC system decides it’s not up for the challenge. That’s why fall is the perfect time to give your system some TLC. Here’s your ultimate fall HVAC maintenance checklist — Houston style.

Here’s a not-so-fun fact: the average home loses 20–30% of conditioned air through leaky ductwork. Translation? You’re paying to cool your attic, your crawlspace, and possibly your neighbor’s attic too. Your ducts are the hidden highways of your HVAC system, quietly moving air from point A (your unit) to point B (your living room). But when they spring a leak, those highways turn into toll roads you’re footing the bill for. So how do you know if your ductwork is betraying y

Smart thermostats are the fancy coffee makers of HVAC — everyone’s talking about them, they look sleek on your wall, and they promise to make your life easier. But do you really need one, or is this just another shiny gadget trying to take your money? Let’s break it down.

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. But here’s the deal — most of what you’ve heard about Freon (and other refrigerants) is about as accurate as a weather forecast from 1987. Let’s clear the air.

Houston summers are no joke. We’ve got heat that could fry an egg on your driveway and humidity that makes you question every life choice involving a blow dryer. But what happens when your AC decides it’s going to pull an all-nighter… every night? While it might seem like your system is just trying to help, an AC that runs nonstop can be a sign something’s not right — and it can run your energy bill higher than a Buc-ee’s billboard.

Summer in Texas hits hard — and when your A/C decides to start blowing hot air, it hits even harder. One moment you're standing in front of a vent expecting sweet relief, and the next you're wondering whether your A/C is working or if you're just imagining it. At Velocity Air A/C & Heating, we hear this complaint all the time, especially once temperatures reach “walking into a sauna” levels.

When it comes to your home’s HVAC system, size definitely matters — and not in the cheeky way you think. A system that’s too small will leave you sweating through Houston summers, and a system that’s too big will short-cycle, waste energy, and create hot-cold swings that drive homeowners crazy. Let’s break down how to choose the right size HVAC system — and why guessing based on your old system is one of the biggest mistakes homeowners make.

Ah, summer in Houston — when the humidity hugs you tighter than your grandma at Thanksgiving and your air conditioner becomes your best friend. But if you start noticing tiny, fuzzy bugs fluttering near your vents, your HVAC system might be hosting some uninvited guests: drain flies. Also called moth flies or sewer gnats, these little pests thrive in warm, damp environments — and your A/C’s condensate drain line or drip pan is the perfect vacation spot.

In the heating, ventilation and air conditioning industry, where trust and technical know-how are everything, Velocity Air A/C & Heating has quickly established itself as a reliable name for both commercial and residential services in Houston.

Your HVAC system works hard to keep your home comfortable through Houston’s wild weather — from scorching summers to chilly winter fronts. Without regular maintenance, though, your system can lose efficiency, break down unexpectedly, or shorten its lifespan. Following a seasonal HVAC maintenance checklist helps prevent costly repairs, improve energy efficiency, and keep your system running smoothly year-round.
