What is two-stage heating?

With two-stage heating, furnaces may operate on two different levels: high and low. Since you can heat your home on the low setting a majority of the time, a two-stage furnace can run longer and more efficiently. Two-stage heating also works more quietly than traditional furnaces and can provide more even heat distribution and fewer temperature swings.

What is Precise Comfort technology?

Lennox’s Precise Comfort™ technology is an operating and control system that allows a furnace to adjust heat and airflow by amazingly small amounts, as low as a 1 percent change. The system is automatic and operates similar to cruise control, making adjustments gradually to meet your comfort demands with energy efficiency.

Will my new furnace work differently than my old one?

Depending on how old your previous furnace was, you could experience a variety of differences. Furnaces today are designed to offer more even and efficient heating than ever before. Modern furnaces also better regulate temperature and air flow, moving more air over the heat exchanger than older furnaces.

Additionally, new furnaces are crafted to integrate with other high-efficiency HVAC products, such as air conditioners. The air conditioner blowers provide your heating system an extra bump so it can deliver cool air around your home efficiently. Special features like variable speed motors will also help reduce noise associated with operating your equipment and easily meet your family’s airflow needs.

What is the energy efficiency standard for air conditioners?

The Department of Energy recently increased the minimum efficiency levels for air conditioners, heat pumps and packaged units made after Jan. 1, 2015, since heating and cooling contributes significantly to a home’s total energy usage. The requirements vary by region, so call Air Today Heating & Cooling for the efficiency standards for the North Dallas area.

How can I reduce my energy costs?

Heating and cooling makes up a large portion of your monthly utility bill. Purchasing HVAC equipment with high efficiency ratings, such as SEER for air conditioners and AFUE for furnaces, is a simple step that can go a long way in lowering energy output. Beyond these ratings, also think about:

  • Routine maintenance – regularly having a pro tune-up your equipment will keep it running at its highest potential.
  • Adding a zoning system – by focusing your heating and cooling on the rooms you use most frequently, you won’t have to pay to heat or cool areas of your home that aren’t routinely used.

Installing a programmable thermostat – the Department of Energy estimates that a programmable thermostat can lower heating costs by up to 35 percent and cooling costs by up to 25 percent. Leave it up to your thermostat to turn down the heat when you’re away and return to your preferred temperature when you’re home.

How can I improve my home's indoor air quality?

Increasing your home’s indoor air quality starts with four basic strategies:

  • Eliminate – poor indoor air quality leaves your home full of with air pollutants floating around your home, so to improve IAQ, the first step is to eliminate as many pollutants as possible. You can easily do this is by cleaning and vacuuming at least once a week, frequently washing linens and storing cleaning products safely.
  • Ventilate – proper insulation is great for keeping your home warm in the winter and cool in the summer, but it also makes it harder for airborne pollutants to escape. Products like our Healthy Climate® ventilation system help exchange stale air for fresh, filtered outside air.
  • Clean – good ventilation and frequent cleaning are a start, but Healthy Climate® air filters, germicidal lights and PureAire™ purification systems take your IAQ to the next level by holding microscopic particles, killing germs and removing particles and germs while destroying chemical vapors.
  • Monitor – programmable thermostats will help you keep an eye on the humidity levels and temperature to help prevent particles and germs from building up and keep your home comfortable.
How do I know which indoor air quality product will work best for my home?

Our Healthy Solution Finder lets you select details specific to your family and home and will help you find equipment best suited to meet your needs. You may also consult with Air Today Heating & Cooling pros who can make a recommendation based on their evaluations of your home and current indoor comfort system.

How does an air conditioner work?

You may be surprised to learn that air conditioners don’t technically make your home cooler; they actually remove the hot air and transfer it outside. This hot air is pushed across a refrigerant coil on the indoor unit and then is sent to the outdoor unit where it is released. Your air conditioner transfers as much hot air outside as is necessary to reach the temperature you have set on your thermostat.

What is the minimum energy efficiency standard for air conditioners in my state?

Different regions have different minimum energy efficiency standards. Additionally, air conditioners, heat pumps and packaged units made after Jan. 1, 2015, have higher minimum efficiency levels than HVAC products manufactured prior to that date. The team at Air Today Heating & Cooling can help you determine the minimum requirements for the North Dallas area, let you know if your current equipment meets those requirements or help you find a replacement air conditioner that does.

How can I confirm the model and serial numbers of my cooling unit?

Your system’s service panel should have a white label on it, with your system’s model and serial numbers at the top. M/N signifies the system’s model number and S/N is the serial number.

What size equipment do I need for my home?

Since equipment size needs are different for every home, the best way to determine the right size equipment for your home is to have a technician from Air Today Heating & Cooling come out to perform load calculation tests. The tests take things like square footage, insulation value and amount, and more into account to determine your home’s HVAC equipment needs.

Can frost, ice, dirt or other debris keep the outdoor unit of my cooling system from operating effectively?

Yes – debris can inhibit your system’s ability to function effectively. It’s normal for heat pumps to have frost or ice on them during the winter, but many include defrost controls so they can work efficiently regardless of the weather conditions.

What is two-stage cooling?

When a cooling systems has two-stage cooling, it means that there are two levels of operation. This allows the system to work as efficiently as possible since there is one level for milder weather and one for harsher weather that demands the system work harder. Two-stage cooling also enables more even temperatures so you don’t experience extreme differences in temperature. Aside from better efficiency, other benefits of two-stage cooling include quieter operation and improved humidity control.

Why is my cooling unit freezing up?

When your cooling unit freezes up, there are a variety of reasons why it could be doing so. The most frequent reasons include: dirty filters, low refrigerant, a dirty evaporative coil and a faulty blower motor or relay. A dirty filter is something you can take care of as a homeowner, but the others need to be completed by a professional like those at Air Today Heating & Cooling. Contact us at 972-881-1919 with any other questions.

What is the best thermostat to use for my cooling system?

Air Today Heating & Cooling offers a number of great thermostat options for your HVAC systems. The best thermostat for you will depend on variables such as whether you want one that’s programmable or not. No matter what kind of thermostat you’d like – or if you’re looking for something that can fit with a home automation system – call Air Today Heating & Cooling to hear about which thermostats you can choose from. Our team will help you find one that’s best for your system, your family’s needs and your budget.

What is a heat pump?

A heat pump can tackle both your home’s heating and cooling needs, offering you one HVAC system that can be used year-round. In the warmer months, heat pumps act like an air conditioner, capturing the hot air from inside your home and transferring it outside; in the cooler months, this process is reversed. Heat pumps can be very energy efficient and may produce two to three times more heat than the energy needed for the process.

When replacing the outdoor unit, should the indoor unit also be replaced?

At Air Today Heating & Cooling, we do recommend replacing both your indoor and outdoor units at the same time because:

  • Nowadays, outdoor systems are built to work with their matching indoor system for maximum efficiency. When you replace just one of your systems, you may not see the same savings on your energy bills as if you had replaced them together.
  • Thanks to technological advancements, newer systems mean improved efficiency. This is also true for HVAC systems. While the advancements focus on greater heating and cooling efficiency, they also include benefits such as better air handling, filtering and noise reduction.
  • If your heating and cooling systems are 10+ years old, they need to be replaced. Older models have outdated technology that is likely contributing to higher energy bills due to poor efficiency. So by replacing your indoor system at the same time as your outdoor equipment, both your systems will provide better energy efficiency that helps you decrease your energy bills and keep your home more comfortable.
How can I improve my utility costs?

Your heating and cooling equipment can contribute significantly to your monthly energy costs. However, these costs can be reduced with innovative and high efficiency products. You’ll want to look for high SEER and AFUE ratings when you’re ready to purchase a new air conditioner or furnace, respectively, as higher SEER and AFUE ratings signify higher efficiency products. If you’re not purchasing new heating and cooling equipment, consider factors such as:

  1. Maintenance: Furnaces, air conditioners and other HVAC equipment operate more efficiently when they are regularly maintained.
  2. Zoning: When parts of your home are rarely used, you’re spending more money to heat or cool them to the same temperature as the rest of the house. A zoning system allows you to section off different parts of your home and control the temperature by each area.
  3. Programmable Thermostats: Programmable thermostats may help you lower your heating costs by 35 percent and your cooling costs by 25 percent, according to the U.S. Department of Energy.
Why should I get a zoning system?

A zoning system allows you to divide your home and heat or cool each part differently. While these systems work well for homes that have areas that are rarely used, they may also be beneficial in situations where you and your family can’t agree on the temperature in certain parts of your home. There are a variety of additional benefits of zoning systems, including efficiency and comfort. View our selection of zoning systems or give Air Today Heating & Cooling a call to see how a zoning system could work for your home.
