AIR MAX HVACR LLC We take great pride in our experience, expertise, quality, and customer service that we provide to meet our consumer's needs. In order to understand expectations of our customers, we take great care to work and communicate with everyone in a professional manner. Our reputation is based on service, safety, and quality, regardless of how large or small the job.

"I have used this company twice. I first gave them a call over the summer for an emergency central AC issue. They were able to quickly come out, ID the problem and fix it the same day for a very reasonable price. They did so well that I called them again a couple of weeks ago when I tried to flick my furnace on for the first time and nothing happened. When it rains, it pours, right? Once again, Air Max was able to quickly respond and found a simple sensor problem and the whole visit took less than an hour and cost me under $100. I feel like I would have been out at least a grand calling another company. I TRUST these guys!"

FAQs for thermostat installation and replacement projects in Severn, MD

Smart thermostats may be worth it for many homeowners. They come with various features, including voice control and smartphone apps. Vacation mode can help lower energy usage when you’re out of town for an extended period. Alert warnings let you know about major spikes or drops in temperature. Smartphone apps can track energy usage, and smart thermostats can learn your routine over time to adjust your temperature and reduce wasted energy consumption automatically.

You typically do not need more than one smart thermostat. While it’s common to see multiple mechanical thermostats throughout a large home, multiple smart thermostats may try to override each other. This can lead to problems with the HVAC system. Ensure the unit you buy has the option for dual- or multi-zoned systems to avoid compatibility issues.

Installing a programmable or smart thermostat may save you $180 per year in utility costs. A big part of this comes from a smart thermostat’s ability to learn and adapt to your regular routines. With smartphone apps or web-based interfaces, you also have the option to control your thermostat when you’re not home.
