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!"

Beltway Air Conditioning & Heating is locally owned & operated out of Hanover, MD. We are Lennox Premier Dealers & are BBB accredited with A+ ratings & reviews - We provide services & installations within a 50 mile radius of home base. Our team specializes in installing and servicing heating, cooling & ventilation equipment, whether it is a small A/C repair or a commercial rooftop - our team is trained to take care of all your HVAC needs! We bring extensive experience and professionalism to every home and commercial building. Our work reflects our passion! The Best Price + The Best Work = Your Best Value. We have uniformed & well-trained staff that under goes background checks and drug screening upon hire and randomly. All of our service professionals are also licensed to work in the state of Maryland.

"We are a bit disappointed by Beltway. While we do appreciate some of their efforts in trying to remedy the situation, the overall experience has been quite negative. Please see reasons below: 1. A brand new HVAC system that was installed on Wednesday completely failed by Saturday morning - which was less than 3 days of installation. This calls into question the quality of Beltway’s product or job, or both. 2. Weekend messenger centers have been extremely frustrating and unhelpful, basically saying that Beltway does not serve customers during non-business hours and that customers just have to deal with Beltway’s issues on their own. We called 4 times this weekend out of desperation. Yet each time they showed no sympathy on the fact that our baby has been suffering through the 80 to 90-degree heat trying to nap. 3. A weekend technician was finally sent on late Sunday afternoon (thanks to owner’s stepping in); however his timing messed up weekend plan as one of us had to stay home and completely missed our good friend’s son’s high school graduation party (now people at the party learned about Beltway…). 4. Unfortunately, this weekend technical was unable to solve the problem and decided to leave us with 2 portable cooling units, which, unfortunately, were extremely loud and inefficient in cooling down, so most of us weren’t able to sleep, just like the night before. Felt like all of their products that we’ve coped with in the past 5 days have been nothing but disappointing. 5. Finally, the full crew came on Monday. But their timing here again messed up the baby’s nap schedule - as the upstairs system was right next to the nursery. This is our first time hiring Beltway. The amount of inconvenience and frustration that they had created in the past 3 days was unbelievable. The experience has been quite negative from multiple aspects, calling into question not only their customer service ability/arrangement but also quality of their products and jobs. We don’t know if we can trust Beltway again or hire them again."

Thermostat installations and replacements FAQs

It's often worth replacing your old thermostat with a newer model that can enhance your home's comfort and energy efficiency. Upgrading to a programmable or smart thermostat can save you up to $200 per year on energy bills. Plus, smart thermostats offer convenient features like remote control and learning capabilities, making your home more comfortable and easier to manage.

Signs of a bad thermostat include your HVAC system not turning on when it's supposed to or failing to reach the desired temperature. If the thermostat's display is blank or not functioning properly, it could be malfunctioning. Another indicator is the HVAC system running continuously without shutting off or cycling on and off too frequently. You might also notice uneven temperatures throughout your home, with some rooms being too warm or too cold. These issues suggest that the thermostat is failing and may need repair or replacement to ensure your HVAC system operates efficiently.

A thermostat should last between 10 to 20 years, depending on its quality and how well it's maintained. Over time, dust, wiring issues, and general wear can affect its performance. Even if a thermostat is still functioning after 10 years, you might choose to replace it to take advantage of newer energy-saving technologies and smart home integrations. Upgrading to a modern thermostat can improve efficiency, offer more control over your home's climate, and potentially lower energy bills.

The number of thermostats you need depends on your home's size, layout, and heating and cooling zones. In a standard single-zone HVAC system, one thermostat controls the temperature for the entire home. However, larger homes or those with multiple floors might benefit from multiple thermostats linked to a multi-zone HVAC system. This setup can offer better comfort and energy efficiency: It lets you customize the temperature in different areas, so you're only heating or cooling the spaces you're using.

Replacing a thermostat typically takes a professional technician about one to two hours to complete. If you're swapping out an existing thermostat for a similar model with compatible wiring, the process can be done in less than an hour. However, installing a new thermostat that requires additional wiring, such as a smart thermostat, or moving the thermostat to a new location can extend the time to two hours or more. Complex installations may also involve cutting into drywall or integrating with other home systems, which can add to the duration.

There are a few things that can cause your home thermostat to fail. The most simple one is age and cleanliness. Dirt, grease, dust, and other small particles can clog sensors and cause malfunctions in readings. You may also have a failing power supply and loose connections, and the simplest cause is that it isn't installed in the right place in your home so it can't properly sense air temperature. Repairing a thermostat costs around $210.
