Explore Our Cooling Systems

We offer a variety of cooling systems to suit your home:

Our professional technicians at DNM will assist you in choosing the right-sized furnace, taking into account factors such as:

Central Air: These systems use a network of ducts to deliver cool air throughout your home, ensuring a consistent temperature in every room. Central air conditioners are ideal for larger homes or those with existing ductwork, as they can efficiently cool multiple areas simultaneously. By utilizing a single central unit, they provide even cooling and are often more energy-efficient compared to multiple window units.

Ductless Split: Installed outside, these units cool your room directly and quietly, with the flexibility to control the temperature in individual rooms. Ductless split systems are perfect for homes without existing ductwork or for adding cooling to specific areas like new additions or converted spaces. They are highly efficient, easy to install, and offer zoned cooling, allowing you to set different temperatures in different rooms, enhancing comfort and energy savings.

Heat Pump: Heat pumps transfer heat from the air or ground, cooling your home efficiently by extracting heat from indoors and expelling it outside during summer. Heat pumps are versatile systems that can provide both heating and cooling, making them a year-round solution. They are particularly energy-efficient and environmentally friendly, as they move heat rather than generating it, which can result in lower energy bills and reduced carbon footprint.

By evaluating these factors, we provide tailored recommendations to maximize your energy efficiency and comfort.

Understanding How Central A/C Works

Central air conditioners are designed to work seamlessly with your existing furnace system, drawing warm air from your home into a network of ductwork. This air travels over an evaporator coil where it encounters a refrigerant. The refrigerant absorbs the heat from the air, effectively lowering its temperature before it is recirculated back into your home. This process ensures that every room receives a consistent and comfortable level of cooling, maintaining a pleasant indoor environment even during the hottest days.

The heat absorbed by the refrigerant is then transported outside to the condenser unit. Here, the heat is expelled into the outdoor air, allowing the refrigerant to cool down and return to the evaporator coil inside your home to repeat the cycle. This efficient transfer of heat not only cools your home effectively but also helps in maintaining energy efficiency, as the refrigerant continuously cycles through the system without needing to be replaced. With this method, central air conditioners provide a reliable and steady cooling solution that keeps your home comfortable and your energy bills in check.

In addition to its efficiency, the central air conditioning system also offers benefits such as improved indoor air quality. As the air circulates through the ducts, it passes through filters that can capture dust, pollen, and other airborne particles, contributing to a cleaner and healthier indoor environment. This dual function of cooling and air purification makes central air conditioners an excellent choice for those looking to enhance their home’s comfort and air quality.

Benefits of Central A/C

Thinking about central air conditioning for your home? Here’s why it’s a great choice:

Efficient Cooling: One of the standout advantages of central air conditioning is its ability to cool multiple rooms simultaneously. Unlike window units or portable air conditioners, which can only cool a single area at a time, a central system distributes cool air evenly throughout your home using a network of ducts. This ensures that every room maintains a comfortable temperature, eliminating hot spots and providing consistent cooling no matter where you are in the house. This efficiency is particularly beneficial for larger homes or spaces with multiple rooms that need to be cooled.

Humidity Control: Central air conditioning systems not only cool your home but also help control indoor humidity levels. High humidity can create an uncomfortable living environment and promote the growth of mold and mildew. By reducing the moisture in the air, central air conditioners help prevent these issues, making your home more comfortable and healthier. Lower humidity levels also protect your furniture, walls, and other belongings from moisture damage, preserving your home’s interior.

Improved Air Quality: Another significant benefit of central air conditioning is the improvement of indoor air quality. As the air circulates through the system, it passes through filters that trap dust, pollen, pet dander, and other airborne particles. This filtration process removes contaminants from the air, providing cleaner and healthier indoor air for you and your family. This is particularly advantageous for individuals with allergies or respiratory conditions, as it can reduce symptoms and promote better overall health.

Longevity: Central air conditioning systems are known for their durability and long lifespan. With proper maintenance, these units can last between 10 to 15 years, providing reliable cooling for many years. This longevity means that once you invest in a central air conditioning system, you can enjoy its benefits for a significant period without the need for frequent replacements. Regular servicing and prompt attention to any minor issues can help extend the life of your system even further.

Cost-Effective: While the initial installation cost of a central air conditioning system might be higher compared to other cooling options, it proves to be cost-effective in the long run. Central systems are more energy-efficient, which can lead to lower utility bills. They are designed to cool your home more efficiently, reducing the amount of energy required to maintain a comfortable temperature. Over time, the savings on energy bills can offset the initial investment, making central air conditioning a financially sound choice.

Low Maintenance: Maintaining a central air conditioning system is relatively straightforward and requires minimal effort. Regular maintenance tasks, such as changing filters, cleaning ducts, and having annual inspections by a professional, can keep your system running smoothly. These routine checks help identify and address any potential issues before they become major problems, ensuring that your system operates efficiently and effectively with minimal downtime.

Increased Home Value: Installing a central air conditioning system can significantly enhance your home’s value. Prospective buyers often view central air conditioning as a desirable feature, especially in regions with hot summers. A well-maintained and efficient central cooling system can make your property more attractive to buyers, potentially increasing its market value and appeal. This investment not only improves your current living conditions but also adds long-term value to your home.

Ease of Use: Central air conditioning systems are designed to be user-friendly and simple to operate. Most systems come with programmable thermostats that allow you to set and adjust temperatures easily. You can create cooling schedules that align with your daily routines, ensuring that your home is comfortable when you need it to be without wasting energy. Advanced models even offer remote control options via smartphone apps, giving you the convenience of adjusting settings from anywhere.

Quiet Operation: Unlike noisy window units or portable air conditioners, central air conditioning systems operate quietly. The main components, such as the compressor and condenser, are located outside your home, reducing indoor noise levels. The indoor unit, typically housed in a basement or utility room, distributes cool air through ducts with minimal sound. This quiet operation ensures a peaceful indoor environment, allowing you to relax, work, or sleep without disturbance.

Types of Central Air Conditioners

Thinking about central air conditioning for your home? Here’s why it’s a great choice:

Split Systems: Split systems are a popular choice for central air conditioning and consist of two main components: an outdoor unit, which houses the condenser and compressor, and an indoor unit, which contains the evaporator. This type of system is particularly advantageous if your home already has a furnace with existing ductwork, as the evaporator coil can be integrated seamlessly into the furnace’s supply duct. The outdoor unit is usually placed on a concrete pad next to the house, while the indoor unit is typically located in the basement, attic, or a dedicated closet.

The split system design allows for efficient cooling of the entire home by distributing cool air through the existing ductwork. This setup not only provides consistent temperature control but also offers the flexibility to cool specific zones within the home, enhancing overall comfort. DNM Heating & Cooling specializes in installing split systems that maximize efficiency and performance, ensuring that your home remains comfortable even during peak summer heat. Our expert technicians will help you choose the right system and ensure it is installed correctly for optimal performance.

Packaged Systems: Packaged systems combine all the necessary components of an air conditioning system into a single, compact unit. This all-in-one solution typically houses the evaporator, compressor, and condenser in one cabinet, which is usually installed outside on the ground or on the roof of your home. This configuration eliminates the need for a separate indoor unit, making it an excellent choice for homes with limited indoor space or where installing a split system is not feasible.

The air ducts connect directly to the packaged unit, which simplifies the installation process and reduces the amount of indoor equipment required. Packaged systems are known for their ease of maintenance, as all components are housed in one location, making service and repairs more straightforward. Additionally, these systems are often designed to provide both heating and cooling, offering a versatile solution for year-round comfort.

Any questions?

Central air conditioning systems provide uniform cooling throughout your home, improve indoor air quality by filtering and dehumidifying the air, and can be more energy-efficient for larger homes compared to multiple window units. They also operate more quietly and are more aesthetically pleasing as they are integrated into the home’s existing ductwork.

It’s recommended to have your central air conditioning system serviced at least once a year, preferably before the cooling season begins. Regular maintenance helps ensure the system operates efficiently, reduces the likelihood of breakdowns, and extends the lifespan of the unit.

Signs that your central air conditioner may need repair or replacement include weak airflow, warm air blowing from the vents, unusual noises (like grinding or squealing), frequent cycling on and off, increased energy bills, and an inability to maintain a consistent temperature. If your system is over 15 years old and experiencing frequent issues, it might be time to consider a replacement.

Ductless mini-split systems consist of an outdoor unit connected to one or more indoor air handlers by a conduit. The conduit houses the power cable, refrigerant tubing, suction tubing, and a condensate drain. These systems provide zoned cooling by delivering conditioned air directly into different areas of your home, allowing for individual temperature control.

Ductless mini-split systems offer several advantages, including improved energy efficiency, flexible installation options, and the ability to provide zoned cooling. They are ideal for homes without existing ductwork and can be easier and less expensive to install. Additionally, they allow for individual temperature control in different rooms, enhancing comfort and potentially reducing energy costs.

Yes, a heat pump can be used for cooling in the summer. Heat pumps work by transferring heat from the inside of your home to the outside, effectively cooling the indoor space. They provide an energy-efficient alternative to traditional air conditioners.

Ductless mini-split systems are generally more energy-efficient than central air systems because they eliminate the energy losses associated with ductwork. According to the U.S. Department of Energy, duct losses can account for more than 30% of energy consumption for space conditioning, especially if the ducts are in unconditioned spaces like attics.

If your air conditioner is not cooling properly, check the thermostat settings first to ensure they are correct. Make sure the air filters are clean and not blocking airflow. Check the outdoor unit to ensure it is free of debris. If these steps don’t resolve the issue, it could be due to low refrigerant levels, a malfunctioning compressor, or other technical problems. Contact a professional HVAC technician for a thorough inspection and repair.

To improve the efficiency of your cooling system, ensure regular maintenance, clean or replace air filters regularly, seal and insulate ductwork, use a programmable thermostat to control temperatures, and keep blinds or curtains closed during the hottest part of the day. Additionally, make sure the outdoor unit is clear of debris and has adequate airflow.

The lifespan of cooling systems can vary depending on the type, quality, and level of maintenance. On average, central air conditioning systems and heat pumps can last 15-20 years, while ductless mini-split systems typically last 12-15 years. Regular maintenance and timely repairs can help extend the lifespan of these cooling systems.
