Types of Thermostats We Install

The right thermostat can make a noticeable difference in your home’s comfort and energy efficiency. At Semper Fi Heating & Cooling, we install a variety of thermostat options to match your home comfort system, lifestyle, and budget. Our team will help you choose a model that gives you the features and control you’re looking for.

Smart Thermostats

Smart thermostats let you control your home’s temperature from your smartphone, tablet, or other connected devices. Many models can learn your schedule, provide energy usage insights, and automatically adjust settings to improve comfort and efficiency.

Programmable Thermostats

Programmable thermostats allow you to create customized heating and cooling schedules based on your daily routine. By automatically adjusting the temperature throughout the day, they can help reduce unnecessary energy use while keeping your home comfortable.

Wi-Fi Thermostats

Wi-Fi thermostats provide remote access to your HVAC system from virtually anywhere with an internet connection. They’re a convenient option for homeowners who want greater flexibility and control over their home’s comfort.

Thermostat Replacement

If your existing thermostat is outdated, inaccurate, or no longer working properly, we can replace it with a modern model that’s compatible with your heating and cooling system. Our technicians will ensure it’s installed correctly and calibrated for reliable performance.

Should You Replace or Repair Your Thermostat?

A malfunctioning thermostat doesn’t always mean you need a replacement. In some cases, a simple repair or recalibration can restore accurate temperature control. However, if your thermostat is older, frequently loses its settings, displays incorrect temperatures, or isn’t communicating properly with your HVAC system, installing a new model may be the better long-term solution. Modern thermostats offer improved accuracy, smart home compatibility, and energy-saving features that many older units simply can’t provide. At Semper Fi Heating & Cooling, we’ll inspect your current thermostat, explain your options, and recommend the solution that makes the most sense for your home and comfort goals.

Isaiah did a great job flushing out my hot water heater. He was personable and professional while pointing out the reasons I needed to consider replacing my 18 yo unit. $49 was a great deal imo. I’d use Semper Fi again. ⭐️⭐️⭐️⭐️⭐️

They answered the phone on a holiday weekend, had a tech onsite in a few hours, brought in a temporary solution for the night and had people replacing the system the next day.

Same day service, technician was out to the house quick and diagnosed the problem. Within a few hours I had 2 technicians show up with all new equipment and started doing a whole system change. They stayed until the job was finished. Victor and Jason were very dedicated to ensuring the job was done correctly. So far a great experience with semper fi!

Brandon and Andrew were wonderful workers. They were extremely caring from the moment they came into my house till they left. They took time to make sure our unit was working at tip top shape and completely explained how my A/C works. They took before and after pictures of the places they worked on and were very proactive with Cleaning. As a senior on a fixed income the price for the tune up was extremely affordable. I cannot express how thankful I am to Brandon and Andrew for their mindfulness and honesty through this appointment. They are truly valued team members. Thank you Semper Fi for putting veterans/ military families first.
