Keeping your home cool during the scorching Las Vegas summers isn’t just about setting the thermostat and hoping for the best. The intense desert heat means your HVAC system works overtime to keep indoor temperatures comfortable. However, many homeowners unknowingly make costly mistakes that reduce efficiency, increase energy bills, and shorten the lifespan of their systems. At Air Duct LV Heating & Cooling, we’ve seen these issues firsthand and are here to help you avoid them.
As your local HVAC repair Las Vegas experts, we’re sharing the most common cooking mistakes homeowners make—so you can enjoy a cooler home, lower energy bills, and longer-lasting equipment.
Ignoring Regular HVAC Maintenance
One of the biggest mistakes homeowners make is skipping routine maintenance. Your cooling system needs regular checkups to function at its best. Over time, dust, dirt, and debris build up in your air ducts and components, causing your system to work harder than necessary.
Scheduling seasonal maintenance with a certified HVAC repair Las Vegas technician ensures your system is clean, efficient, and ready to take on extreme temperatures. Air Duct LV Heating & Cooling recommends scheduling a maintenance appointment at least once a year, ideally before the peak summer months.
Setting the Thermostat Too Low
Setting your thermostat too low won’t cool your home faster—it just makes your HVAC system work harder and longer. Not only does this waste energy, but it also increases wear and tear on your unit.
Most experts recommend keeping your thermostat between 74°F and 78°F when you’re at home during the summer. If you’re away, increasing the temperature by a few degrees helps reduce energy usage without sacrificing comfort.
Smart thermostats can help maintain a consistent temperature while reducing energy consumption. If you’re unsure which thermostat is best for your home, our Las Vegas HVAC pros can help with recommendations and installation.
Closing Vents in Unused Rooms
Many people believe that closing vents in unused rooms saves energy. In reality, doing so disrupts airflow and puts additional strain on your HVAC system. Your system is designed to cool your entire home based on a balanced flow of air. When you close vents, pressure builds up in the ductwork, which can lead to leaks and reduced efficiency.
Instead, keep all vents open and consider using zoning systems or programmable thermostats to control the temperature in different areas of your home more effectively.
Forgetting to Change Air Filters
A clogged or dirty air filter is one of the most common and easily preventable issues that can lead to HVAC repair in Las Vegas. Dirty filters restrict airflow, making your system work harder and increasing the risk of breakdowns.
Air filters should be checked monthly and replaced every 1-3 months, depending on usage and whether you have pets or allergies. Clean filters not only improve air quality but also help your system run more efficiently, saving you money over time.
Neglecting Your Air Ducts
Even if your HVAC unit is functioning perfectly, dirty or leaking air ducts can undermine your cooling efficiency. Leaks in the ductwork can cause up to 30% of cooled air to escape, especially in older homes.
That’s why air duct cleaning in Las Vegas is so important. At Air Duct LV Heating & Cooling, our team inspects and seals ducts to ensure your system is distributing air properly. This service not only boosts system performance but also helps improve indoor air quality by removing dust, allergens, and contaminants from your ducts.
Incorrect HVAC Sizing
Another issue we often encounter during HVAC repair Las Vegas visits is improperly sized systems. An HVAC unit that’s too small will struggle to keep your home cool, while one that’s too large will cycle on and off frequently, wasting energy and wearing out faster.
Proper sizing is critical for comfort, efficiency, and long-term durability. If your system doesn’t seem to be keeping up or runs constantly, it may be time for a professional evaluation. Our experts can assess your home’s needs and recommend the right system size to maximize cooling performance.
Relying Too Heavily on Ceiling Fans
Ceiling fans help move air around the room, but they don’t actually lower the temperature. Relying on fans alone won’t do much to cool your home if your HVAC system isn’t operating efficiently. That said, using fans in conjunction with a properly working AC system can help circulate cool air and reduce your energy bills slightly.
Just remember to turn off fans when you leave a room—fans cool people, not spaces.
Blocking Airflow With Furniture or Curtains
Homeowners sometimes unknowingly block vents with furniture, rugs, or curtains, limiting the airflow in their homes. This forces your HVAC system to work harder and less effectively.
Make sure all vents and registers are unobstructed to allow for even air distribution. During routine inspections, our Las Vegas HVAC repair technicians can help identify problem areas and offer suggestions to improve airflow throughout your home.
Skipping Professional Repairs
When your system isn’t cooling properly, DIY fixes can sometimes do more harm than good. Refrigerant issues, electrical components, and ductwork problems require professional attention. Delaying service or using temporary workarounds often leads to bigger and more expensive problems down the road.
Hiring a licensed and experienced HVAC company in Las Vegas ensures your system gets the repairs it needs—done safely, correctly, and efficiently.
