FAQs
Why should I consider upgrading my thermostat instead of keeping my current one?
Older manual or non-programmable thermostats can be off by several degrees, lack scheduling features, and cannot communicate with modern high-efficiency HVAC equipment. Upgrading to a programmable or smart thermostat helps you fine-tune temperature settings, reduce energy waste, automate comfort schedules, and remotely monitor your system through a phone or tablet. In Loudon, where summers are humid and winters can dip below freezing, these finer controls translate into lower energy bills and more consistent indoor comfort year-round.
What types of thermostats do your NATE-certified technicians install?
We offer and professionally install a full range of thermostats, including basic digital units, 7-day programmable models, Wi-Fi connected smart thermostats (Nest, ecobee, Honeywell Home, etc.), and communicating thermostats designed specifically for variable-speed or multi-stage HVAC systems. Our NATE-certified techs will evaluate your current heating and air conditioning equipment, electrical requirements, and preferred features to recommend the model that best fits your goals and budget.
How can a smart thermostat save me money in Loudon’s climate?
Smart thermostats use occupancy sensors, geofencing, and learning algorithms to adjust temperatures automatically when you’re away or asleep. They also provide detailed energy reports, suggesting efficiency tweaks. In Loudon’s mixed climate, you might see 8–15% savings on cooling costs in summer and 10–12% on heating costs in winter, according to ENERGY STAR studies. Over a few years, these savings generally offset the cost of the thermostat and professional installation.
Is it really necessary to have a NATE-certified technician perform the thermostat upgrade?
Yes. A thermostat seems simple, but wiring mistakes can short out control boards, disable safety circuits, or void equipment warranties. NATE certification verifies specialized training on HVAC controls, low-voltage wiring, and equipment compatibility. Our technicians ensure the thermostat is wired correctly, configured for heat pump or dual-fuel operation common in Loudon, updated with the latest firmware, and fully tested so your heating and cooling run safely and efficiently.
Will my existing HVAC system work with a new smart thermostat?
In most cases, yes. The majority of forced-air furnaces, air conditioners, heat pumps, and mini-splits installed in Loudon support 24-volt (low-voltage) thermostat control. During our free on-site evaluation, we check for the required C-wire (common wire), verify stage counts (single-stage, two-stage, or variable-speed), and confirm compatibility with features like dehumidification or dual-fuel lockout. If your system lacks a C-wire or has proprietary controls, we can usually add an adaptor or recommend an alternative thermostat that integrates seamlessly.
How long does a thermostat replacement take, and what should I expect to pay?
A straightforward thermostat swap typically takes 45–90 minutes, including wiring verification, mounting, programming, and user training. More complex jobs—such as adding a C-wire, relocating the thermostat, or pairing it with zoning equipment—may take 2–3 hours. Costs in the Loudon area range from $199–$299 for a basic digital or programmable model installed, and $349–$599 for Wi-Fi smart thermostats, depending on brand and feature set. All pricing is provided upfront, and every installation comes with a workmanship warranty and the thermostat manufacturer’s warranty.
