Smart Home Energy Efficient Thermostat Installation in Alexandria

What are the Benefits of Smart Thermostats?


You can control your thermostat from a cell phone and adjust the temperature inside your home before you walk in the door. Step into comfort that feels nice any time of the year.

Energy Savings

One of the biggest reasons to upgrade to smart thermostats is energy savings. Instead of running your heating and cooling system all day, you can efficiently choose the right temperature at the right time of day.


Smart thermostats can sense when you’re gone and automatically adjust the temperature in your home. You’ll never forget to set your thermostat.

How to choose the right smart thermostat to install in your home?

Most residential whole-home thermostats are either electromechanical, digital, or a combination of both, meaning there are many options available. Our experts will help you select one that is right for your needs and your home.

Customers With a NICE Experience

Customers With a NICE Experience

Barb N.

“I purchased my HVAC unit a year ago along with a Cozy Club maintenance plan. It's been running great and the customer service team is always quick to respond to questions. Today Rolando M. came by for the maintenance check and, as usual, he was neat, professional and maintained the COVID rules. He was also very nice, living up to the company name. I'm very happy with my experience with Nice.”

N. England.

“I can't speak highly enough of this company. I requested an appointment, and it was scheduled for the next day. The technician was polite, honest, and a pure delight to work with. He didn't try to overcharge or tell me to replace something I didn't need to. He made service recommendations that were in line with industry standard prices so I could make an informed decision as he went about his service visit. Would recommend and will be using them again in the future. ”

Lucas W.

“My technician arrived promptly at our appointed hour. He repaired a dirty and non-working gas fireplace. In addition, he found a small gas leak on our furnace line. Overall, exceptional service and quality work. I highly recommend their HVAC service.”

Rona G.

“Very impressive company! Nice responded to my call for a heating issue on very short notice. My tech, was right on time, extremely polite, and very hardworking. Customer service and satisfaction are clearly a priority.”

Kenny D.

“They treat customers like a valuable asset, not like a number. Business the old-fashioned way, that will never go out of style.”

Lois S.

“Superb customer service. Before a service appointment, you receive a text message notification with photo of the tech that will be at your residence followed by a phone call. During a service appointment you'll updated and educated. If there is a concern, management will contact you promptly and follow up until issue resolved. Awesome and attentive team!!”
