Over the past 30-plus years, we’ve had common questions homeowners ask us throughout western Nevada. Many of them have been asked enough times that I felt it important to share.
Does a bigger HVAC system provide better performance?
In short, the answer is no. The size of your HVAC system depends entirely on the total square footage of your home. A system that is too small will run nonstop trying to reach and maintain your desired temperature, whereas a system that is too large will heat and cool your home in frequent, short cycles. Either way, you may end up with a higher energy bill due to an inadequately sized system for your home.

- Consider using a programmable thermostat to control temperatures throughout the day. Or if you’re leaving for more than a couple hours and can remember, set your thermostat 10-15 degrees lower in the winter and 5-8 degrees higher in the summer. Energy Star estimates that users who do this can save 5-15 percent on their energy bill.
- Get your system serviced twice a year, once at the start of air conditioning season and once at the beginning of heat season.
- Make sure your vents are not closed, covered, or blocked by furniture.
- And last but not least, change your filters regularly.

How often should my filters be changed?
Your filters should be changed twice per year at least, during your summer and winter maintenance services. Even better—change them quarterly. Best—during high-use periods, change them monthly.
How long will my HVAC system last?
The length your system lasts is reliant upon how well the unit is maintained. You can expect your HVAC system to roughly last between 15-25 years—IF—the recommended service and maintenance are performed throughout the last of the system. Certain elements of your total system may have different lifespans.
