As West Texas temperatures rise, having a reliable air conditioning system in your home is essential. Whether you’re trying to stay cool at home or keep your business running smoothly, knowing how to maintain, troubleshoot, and repair your AC unit can help you stay ahead of costly summer repairs.
If you have questions about air conditioning or want to learn more about how it works, you’ve come to the right place. At Lowery Plumbing, Heating, and Air Conditioning, we’re here to answer common questions about heating, ventilation, and air conditioning (HVAC) systems, so you can stay informed and keep your cool all summer long.
1. How Often Should I Replace My Air Filter?
For most homes, we recommend replacing your air filter every 1 to 3 months. But here in Lubbock, with heavy wind, dust, and allergies, we recommend checking your air filter monthly and replacing it as needed.
A dirty filter doesn’t just affect airflow. It forces your air handler and compressor to work harder, which increases your energy bill and reduces the lifespan of your AC. Plus, a dirty air filter can reduce indoor air quality, affecting your health. If you’re unsure about the type of air filter that’s best for you, our technicians are happy to help.
2. When Should I Schedule Air Conditioning Maintenance?
At a minimum, we recommend scheduling air conditioning service once a year. Spring is the ideal time for an HVAC inspection, as it allows your technician time to diagnose and make repairs before the high summer temperatures hit. Regular HVAC maintenance helps avoid surprises and keeps your home running in top shape.
A standard tune-up from Lowery includes:
- Coil cleaning (condenser and evaporator)
- Checking refrigerant levels and capacitors
- Inspecting thermostats, circuit breakers, and ducts
- Testing airflow and carbon monoxide detectors
Proactive care reduces HVAC breakdowns and helps your system run at peak efficiency.
3. How Long Does an Air Conditioner Last?
A well-maintained central air conditioner can last 10 to 15 years. Factors like Lubbock’s dry climate, dusty air, and usage patterns all play a role in your air conditioner’s lifespan.
If your system needs frequent AC repair, it might be time to consider completely upgrading to a new heating and air conditioning system. Upgrading often comes with better efficiency, longer warranty terms, and potential rebates for energy-efficient models.
4. How Much Does Air Conditioning Repair Cost?
We get this question often: How much does air conditioning repair cost? It depends on the issue, but typical repairs range from $150 to $600.
Smaller fixes—like a blown capacitor or clogged drain line—tend to be on the lower end. Larger issues involving the compressor, ductwork, or blower motor will run higher. Call us for a same-day quote on AC repair nearby.
5. What Can I Do If My AC Isn’t Working?
Before calling for emergency air conditioner repair, try this quick checklist:
- Is your thermostat set to “cool” and a lower temp than the room?
- Has your circuit breaker tripped?
- Is your air filter dirty?
- Are there any obstructions around the outdoor condenser unit?
If everything checks out and you still don’t have cool air, it could be a refrigerant leak, frozen coil, or electrical issue. That’s when it’s time to call the HVAC pros.
6. Why Is My Air Conditioner Freezing Up?
If your air conditioner is running but you notice ice forming, you may have:
- Low refrigerant
- Blocked airflow (dirty filter or clogged ducts)
- Issues with the evaporator coil or air handler
- Poor ventilation or humidity control
Letting the ice melt is a good start, but it won’t fix the problem. If you notice this issue, call a professional for HVAC troubleshooting to address the underlying cause and avoid water damage.
7. What’s the Best Temperature for Summer Comfort?
The ideal temperature for your air conditioner in the summer truly depends on your personal preferences and energy efficiency goals. Most people find a temperature between 72°F and 78°F comfortable.
To get the most energy savings without sacrificing comfort, aim for 78°F when you’re home. A smart thermostat can raise the temperature automatically while you’re away, helping you save as much as 10% a year on heating and cooling costs. If you need help programming your smart thermostat for the summer, we can assist during your next HVAC service visit.
8. What Size Air Conditioner Does My Home Need?
Air conditioner size isn’t one-size-fits-all. It depends on:
- Home square footage
- Window placement
- Insulation
- West Texas climate conditions
If your AC is too small, it runs constantly. Too large, and it short-cycles. A Manual J load calculation from a licensed HVAC contractor ensures your system fits your space.
9. How Much Does a New Heating and Air Conditioning System Cost?
Central air conditioning systems typically cost between $3,300 to $7,800 installed. This will vary depending on brand (Carrier, Daikin, American Standard, etc.), ductwork, system type, and installation complexity. A mini-split or ductless system may cost a bit more upfront, depending on how many units you need, but offers greater long-term energy savings. Be sure to ask your HVAC technician about financing options or local rebates for energy-efficient installations.
10. What’s the Best HVAC System for My Home?
The best system depends on your budget, space, and goals. In Lubbock, heat pumps, variable refrigerant flow (VRF) systems, and radiant heating and cooling systems offer energy savings and comfort.
At Lowery, we carry high-efficiency units from trusted manufacturers and help you find the right match for your home or business.
