Your Questions Answered
Modern thermostats do more than just control temperature – they learn your schedule, adjust automatically for weather changes, and can be controlled remotely from your smartphone.
Updated September 2026.
Can I really save enough money with a new thermostat to justify the installation cost? A
Absolutely – most homeowners save $150-300 annually on energy bills with a properly installed programmable thermostat, meaning it pays for itself within the first year. Smart thermostats with learning capabilities and remote access can save even more by automatically adjusting when you're away and optimizing your system's performance based on your actual usage patterns.
Why should I hire a professional instead of installing a thermostat myself?
Incorrect wiring can damage your HVAC system's control board, resulting in expensive repairs that cost far more than professional installation. NexLvl Services technicians ensure proper compatibility, correct wiring, accurate placement, and optimal programming for your specific system – plus we provide warranties on both the equipment and installation that protect your investment.
What’s included in NexLvl Services AC maintenance service?
Our comprehensive maintenance service includes a full system inspection, filter replacement, coil cleaning, refrigerant level check, thermostat calibration, and performance testing to keep your system running at peak efficiency.
What's the difference between basic programmable and smart thermostats, and which should I choose?
Basic programmable models allow you to set schedules and can save 10-15% on energy costs, while smart thermostats offer app control, learning algorithms, energy reports, and integration with home automation systems for 20-25% savings. We help you choose based on your lifestyle, technical comfort level, and budget – both options provide significant savings compared to old manual thermostats.
How often should I schedule AC maintenance?
We recommend professional AC maintenance at least once a year—preferably in the spring before peak usage. Regular service helps extend the life of your unit, maintain energy efficiency, and reduce the risk of breakdowns.
