1. Change Your Air Filters
Replacing or cleaning air filters is the simplest but most impactful step on your pre-winter HVAC checklist Las Vegas. Dirty filters restrict airflow, causing heating systems to work harder, which increases energy usage and wear on components.
During the winter, run times increase, so change filters every 1–2 months. Choose high-quality pleated filters rated MERV 8-11 to balance efficiency and airflow.
2. Test and Calibrate Your Thermostat
Thermostat accuracy is crucial. An uncalibrated thermostat can cause your system to run inefficiently or turn on/off at the wrong times—draining energy and compromising comfort.
When preparing your pre-winter HVAC checklist Las Vegas, check that your thermostat responds accurately. If it’s old or malfunctioning, consider upgrading to a smart thermostat. Smart units learn your schedule, improve efficiency, and provide energy reports.
3. Check Heating System Operation
Before the chill hits, test your heating system in stages:
- Set your thermostat to heating mode and raise it a few degrees.
- Confirm the blower runs, the burner engages, and warm air flows through vents.
- Listen for unusual noises like rattling or whining—and watch for odd odors or delays.
- Monitor startup time; significant lag can indicate ignition or airflow problems.
Step 3 is a critical part of your pre-winter HVAC checklist Las Vegas—and a test you’ll appreciate when winter arrives.
4. Inspect Ductwork and Vents
Leaky or poorly insulated ducts waste heated air—costing you comfort and money. On your pre-winter HVAC checklist Las Vegas, inspect accessible ducts for noticeable gaps, disconnected seams, or insulation issues.
Tighten loose connections with foil tape or mastic sealant. Also, vacuum or brush vents to remove dust and ensure unobstructed airflow.
5. Clean Coils and Plan Preventative Maintenance
Clean evaporator and condenser coils improve heating efficiency even in the winter.
As part of your pre-winter HVAC checklist Las Vegas, schedule a professional HVAC inspection. Our service covers coil cleaning, blower inspection, refrigerant checks, safety switch testing, and full performance evaluation.
6. Test Safety Shutoffs and Carbon Monoxide Detectors
Safety features are non-negotiable. Your pre-winter HVAC checklist Las Vegas must include a test of safety shutoff switches, emergency float switches, flame sensors, and carbon monoxide detectors.
Replace batteries in detectors and ensure they’re within 5–15 feet of sleeping areas. Faulty sensors or detectors pose serious safety risks—especially when furnace use increases.
7. Check and Clean Condensate Drain
Though heating produces less condensate than AC, condensate from the indoor coil still needs attention. Blocked drains can overflow and cause water damage.
When completing your pre-winter HVAC checklist Las Vegas, inspect condensate lines, clear drain pans, and flush with a vinegar solution if needed. Ensure safety switches function properly.
8. Review Airflow Balance and Temperature Consistency
Assess temperature balance across rooms. Cold spots or uneven heating indicate airflow imbalances—often due to duct or damper issues.
On your pre-winter HVAC checklist Las Vegas, manually open dampers in registers or schedule a duct balancing service to ensure even distribution throughout your home.
9. Seal Windows, Doors, and Insulation Gaps
Your HVAC performance depends on a tight building envelope. As part of a thorough pre-winter HVAC checklist Las Vegas, inspect windows and doors for drafts. Apply weatherstripping and caulk to seal air leaks.
Address attic and wall insulation if needed—proper insulation reduces heater runtime and energy use.
10. Schedule Professional HVAC Tune-Up
After completing DIY items, schedule a professional tune-up for your pre-winter HVAC checklist Las Vegas. A certified technician will perform leak tests, refrigerant inspection, safety control calibration, airflow balancing, and system diagnostics.
Our team also updates filters, logs operating data, and offers recommendations or repairs before heavy winter use begins.
11. Consider Upgrades for Enhanced Winter Performance
If your furnace is older than 10 years or less efficient, winter prep offers a smart opportunity to upgrade. Your pre-winter HVAC checklist Las Vegas may include:
- A high-efficiency furnace (90%+ AFUE) or heat pump
- Zoning for customizable warmth levels
- Smart thermostat upgrades
- Insulation improvements or duct sealing
The added comfort and energy savings you’ll gain all winter long justify these upgrades.
12. Make a Plan for Emergency Service
Winter breakdowns happen. Planning ahead is part of your pre-winter HVAC checklist Las Vegas. Here’s what to prepare:
- Save Mr. Gates Heating and Cooling contact information
- Know your system make/model and warranty details
- Keep professional filter and button supplies on hand
- Ask about 24/7 emergency service plans
- Learn basic system reset procedures
