    Frequently Asked Questions

    You probably already know that your thermostat uses a sensor to detect the temperature in the room. Next, you are able to pick a temperature setting. If your thermostat detects that the actual temperature is too far away from the desired temperature setting, it will turn on your air conditioning or heating system. Once the thermostat senses that the temperature in the space has reached one or two degrees beyond your set temperature, it will turn off your AC or heater. This is how a thermostat keeps your home comfortable.

    A programmable thermostat can save you money on your energy bills. Without a programmable thermostat, most people in DFW leave their HVAC at the same temperature all of the time. However, you really don’t need your home to be conditioned as much when you are at work or away from the home. When you use a programmable thermostat, you can set up your system to automatically change temperatures depending on the time of day. Changing the temperature just one or two degrees can have a major impact on your energy bills over time. So, the cost of a programmable thermostat often pays for itself quickly.

    This is one of the most common questions for HVAC. For air conditioning in Dallas, a good starting point is about 75 degrees. For heating, we recommend about 70 degrees. There are a lot of things that impact your thermal comfort. For example, the clothes you wear, whether or not you use ceiling fans, and how much heat your electronic devices give off. Ultimately, you should set your temperature to whatever makes you most comfortable.

    Air conditioners are sized based on how much energy your home needs to stay cool. The more heat your home has, the larger your air conditioner needs to be. For example, if your walls have poor insulation, your AC must have enough capacity to compensate. But, the most helpful indicator of what size your A/C needs to be is judging whether or not your current A/C is working properly and cooling your home to your desired temperature. A licensed professional can help you identify the right size of air conditioner.

    Just like a vehicle, the lifespan of a furnace or air conditioner depends on how well you have taken care of it. Regular maintenance is key to ensure system longevity. If you have properly serviced your equipment, you can expect an air conditioner to last 11-13 years and a furnace to last 18-20 years. However, technology evolves quickly. Just because a system is still working doesn’t mean it’s always the best choice for your home. An older system can be a real energy hog. Many times, you will be better off replacing your system once it’s older than 10 years. If you have questions about whether or not to replace your HVAC, give us a call. We’d be happy to evaluate your system.

    Don’t worry. A burning smell is normal if it’s the first time you’ve turned on your furnace in a while. In short, your furnace is simply burning off dust particles that have accumulated within the machinery while it’s been dormant. The smell should go away after a few minutes of operation. Still, if you’re concerned, don’t hesitate to call us.

    An Award-Winning HVAC Company That Takes Ethics Seriously

    Why are “ethics” so important in the HVAC industry? If you hire an HVAC company that doesn’t care about ethics, you might experience shoddy or unsafe repair work, hiked up or bait-and-switch products, under-educated technicians, poor customer service, a total runaround, or worse – a technician who isn’t licensed, hasn’t been background checked, and shouldn’t be doing work in your home.

    Fortunately for you, and our other customers, we win awards for ethics. In fact, we’ve been awarded the Torch Award for Ethics from the Better Business Bureau, which is awarded to companies in any industry, nationwide who exemplify ethical and conscientious business practices. We’re very proud of that alongside our other industry-leading awards from Carrier, local awards in our area, and more.
