With two-stage heating, furnaces may work on two different levels: high and low. Since you can heat your home on the low setting most of the time, a two-stage furnace can operate longer and more efficiently. Two-stage heating also works more quietly than traditional furnaces and can give you more even heat distribution and fewer temperature swings.
KDM Service Corporation offers a selection of different brands and models that incorporate advanced technology to cool and warm your home more efficiently. Technology in the newer HVAC systems provides more precision when it comes to supporting your home comfort needs. If you want more information, please reach out to our experts at 205-208-8090.

Depending on how old your previous furnace was, you could experience a variety of differences. Furnaces today are designed to give 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 give your heating system an extra lift 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.

The Department of Energy recently increased the minimum efficiency levels for air conditioners, heat pumps and packaged units manufactured after Jan. 1, 2015, since heating and cooling contributes significantly to a homes total energy usage. The requirements vary by region, so call KDM Service Corporation for the efficiency standards for Tuscaloosa.

There are several ways to decrease your energy costs and one of the best ways is to make sure you have an energy-efficient HVAC system. KDM Service Corporation offers many highly efficient products that will help lower the amount of energy you are using and save you money. In addition to looking for products that have the Energy Star® certification, high SEER ratings for air conditioners or AFUE ratings for furnaces, here are some other things to consider:

  • Remember to book ongoing maintenance and have an experienced professional take a look at your system to make sure its running efficiently.
  • If you have clear areas of your home that you need to heat or cool, you could consider a zoning system. This allows you to target that area and reduces wasted energy on heating or cooling areas that aren't used.
  • Programmable or smart thermostats make it a breeze to maintain your home comfort while not consuming energy to heat or cool your space if you aren't home. It is an easy way to decrease energy costs and once you set it, you can walk away and be confident its going to take care of your indoor comfort.

There are four things to review when increasing your indoor air quality:

  • The indoor air quality in your house starts to suffer when the air begins filling up with air pollutants. The biggest concern is removing these pollutants. Some to-dos to put on your weekly checklist is vacuuming, washing your linens and making sure any cleaning products are stored properly.
  • Especially in newer homes, the insulation is installed so well that it might be challenging for these pollutants to leave the home. While it helps to keep your home warm or cool, depending on the season, its important to get some fresh air inside.
  • Make sure that you have good ventilation and perform routine maintenance on your system. And while that's very beneficial, you can also take your IAQ even further by using air filters, germicidal lights and purification systems to get rid of particles while eliminating chemical vapors.
  • Smart or programmable thermostats can help control humidity levels as well as the temperature. This can help prevent germs and other particles from collecting while maintaining your home comfort.
Each house brings a unique situation, which is why we recommend that you contact our team at KDM Service Corporation to find out which solution will be best for your space. Our experienced technicians will conduct a review of your current system and chat about what your ideal home comfort looks like. That will help us determine which products will be most effective.
You may be surprised to learn that air conditioners don't technically make your home cooler; they actually remove the hot air and direct it outside. This hot air moves across a refrigerant coil on the indoor unit and then is sent to the outdoor unit where it is released. Your air conditioner pushes as much hot air outside as is necessary to reach the temperature you have set on your thermostat.
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 KDM Service Corporation can help you determine the minimum requirements for Tuscaloosa, let you know if your current equipment meets those requirements or help you find a replacement air conditioner that does.
Your systems service panel should have a white label on it, with your systems model and serial numbers at the top. M/N stands for model number and S/N is the serial number.
Since equipment size needs vary by home, the best way to determine the correct size equipment for your home is to have a technician from KDM Service Corporation come out to perform load calculation tests. The tests take factors such as square footage, insulation value and amount, and more into account to determine your homes HVAC equipment needs.
Yes debris can limit your systems ability to function effectively. Its common for heat pumps to have frost or ice on them in the winter, but many include defrost controls so they can work efficiently regardless of the weather conditions.
When a cooling systems has two-stage cooling, it means that there are two levels of operation. This lets the system work more efficiently since there is one level for milder weather and another for harsher weather that demands the system work harder. Two-stage cooling also enables almost unnoticeable temperature changes so you don't experience extreme differences in temperature. Aside from better efficiency, other benefits of two-stage cooling include quieter operation and better humidity control.
When your cooling unit freezes up, there are a number of reasons why it could be doing so. The most typical 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 fixed by a professional like those at KDM Service Corporation. Contact them at 205-208-8090 with any other questions.
KDM Service Corporation has 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 KDM Service Corporation to hear about which thermostats you can choose from. Our team will help you find one thats right for your system, your family's needs and your budget.
A heat pump takes care of both your homes 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 moving 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 used.
At KDM Service Corporation, 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 the most efficiency. When you replace just one of your systems, you may not see the same energy efficiency levels as if you had replaced them together.
  • Thanks to technological improvements, newer systems mean improved efficiency. This is also true for HVAC systems. While the advancements focus on higher 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 adding to your energy costs 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 reduce your energy bills and keep your home more comfortable.
Your home energy system may have a communication module that directs performance stats to an online site or portal. You can visit this to check your system's status, the amount of energy being produced and the positive influence you are having on the environment. You can also take a look at your owner's manual for recommendations on monitoring performance.
Rain will clean the modules automatically in most areas; however, if you live in a dusty area, you may see improved performance after periodically spraying the modules with water. Please note that high-pressure hoses and detergents should never be used to clean solar modules, as they can harm the product.
KDM Service Corporation can help suggest the right thermostat for you based on your home and current heating and cooling equipment. We have a number of programmable and nonprogrammable thermostats, which can help enhance the efficiency of your homes furnace and/or air conditioner. Browse our thermostats or give us a call at 205-208-8090 for more information.

A significant portion of your monthly energy costs can be attributed to your heating and cooling system. It makes sense, because our home comfort is a vital aspect of our day-to-day lives. Fortunately, there are high-efficiency solutions from KDM Service Corporation that can keep you comfortable while also decreasing energy costs. When it's time for you to shop for a new HVAC system, there are a couple things to consider. You'll want to find air conditioners with high SEER ratings and furnaces with high AFUE ratings. These ratings measure efficiency, so the larger the number the better off you'll be when it comes to saving on energy costs. You can also consider these tips:

  • Keep your system operating to its best ability by booking routine maintenance. It helps uphold efficiency and make sure everything is functioning properly.
  • Consider a zoning system if you only have targeted rooms that need to be heated or cooled. There is no need to use energy regulating the temperature in a room that is never, or rarely used.
  • The U.S. Department of Energy states that programmable thermostats can save up to 35 percent on heating costs and 25 percent on cooling costs. There are a lot of programmable and smart thermostat options that are easy to use and vary in the type of features-so you can find an option that you are comfortable with.
A zoning system allows you to divide your house and heat or air condition each area differently. While these systems work well for houses that have parts that are rarely occupied, they could also be helpful in situations where you and your family argue about the temperature in certain parts of your residence. There are a collection of additional benefits of zoning systems, such as efficiency and comfort. View our selection of zoning systems or give KDM Service Corporation a ring to see how a zoning system could benefit your home.
