At Advent, we believe in quality, integrity and trust. One of the ways we express these values is by sharing information with our customers. Above all else, we want to ensure our customers are making informed decisions about their heating and cooling systems. So, on this page we’re sharing answers to some of the frequently asked questions about HVAC from our DFW customers.
Temperature Control Questions for HVAC SystemsHow does my thermostat work?
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.
Do I need a programmable thermostat?
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 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.
What temperature should I set my air conditioner or heater to?
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.
How can I save money on a new thermostat?
Oftentimes, there are rebates available for new thermostats. Rebates can make your new thermostat purchase more affordable. Check out our HVAC Rebates page for more info.
If I set my air conditioner to a lower temperature, will it cool my house faster?
Unfortunately, no. Setting your A/C to a lower temperature will not make your system work faster. It is a common misconception that your system will work harder the lower you set the temperature. Instead, it will work longer. The result is excessive cooling and unnecessary expense. If your air conditioner isn’t working properly, it may be time to call in a HVAC professional.
Air Conditioner and Furnace QuestionsHow big does my air conditioner need to be?
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.
What is a ton in HVAC?
The word “ton” is an expression of HVAC system size. It is the amount of energy a system can produce. 1 Ton is equal to 12,000 British Thermal Units (BTUs). Here’s a fun fact: one ton is equal to the amount of heat required (288,000 Btu) to melt one ACTUAL ton of ice in a 24-hour period.
How long should and HVAC system last?
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.
My heater turned on and it smells like something is burning. What do I do?
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.
Does my air conditioner or furnace qualify for tax credit?
As of 2019, there are no federal tax credits available for air conditioners. The residential energy efficiency tax credit expired on 12/31/2017. Fortunately, there are plenty of other ways Dallas/Fort Worth customers can save money on a new air conditioning system. Manufacturers and local utilities offer rebates and promotions for HVAC systems. Plus, you can combine these rebates with financing for an affordable monthly payment.
Indoor Air Quality and HVAC QuestionsHow often should I change my HVAC filter?
You’re not alone! A lot of people have questions about when to replace their HVAC filter. For the best performance, air filters should be changed every 3 months. If you have pets, or family members with allergies, you should change your filter more frequently. When you keep a dirty filter in an air handler, your system will have to work harder to pull the air through. The result? Your system will use more energy, which means a higher utility bill each month. Check out our online store to get a replacement air filter right now.
Should I open my windows when the weather is nice?
If the weather is nice, opening screened windows and doors can be a great way to get some fresh air into your space. But, make sure to close the windows if your space temperature starts to get uncomfortable. We recommend keeping your HVAC off when your windows are open, and using ceiling fans to help keep rooms comfortable and air flowing. If it’s raining or humid outside, windows should stay closed. Letting too much humidity in your space can cause other problems in your home, such as promoting the growth of bacteria.
How can I protect my home from carbon monoxide?
The first line of defense is a carbon monoxide monitor. You can purchase a CO monitor at any DFW home improvement store. They are very affordable and a must-have safety device. To help prevent carbon monoxide leaks, make sure to have your furnace serviced at least once a year.
