Central AC Installation & Services in El Cajon, СА

Many of us have likely observed the rising summer temperatures or a reduced tolerance for heat as we grow older. This often leads to a desire to replace noisy and drafty window air conditioning with efficient and quiet whole-house central air conditioning systems.

Nonetheless, this concept often remains unexplored. Homeowners who already have forced furnace air conditioning installed express concerns about potential costs and reduced efficiency when modifying their heating systems. For those without existing, the idea of adding them without extensive home renovations and substantial expenses can be intimidating. Nevertheless, the process of adding central air conditioning is more straightforward and cost-effective than one might expect. So, what is the price of central air conditioning installation?

A team of two technicians can usually complete this installation in just two to three days, often requiring minimal or no modifications to the existing airwork.

For homes that necessitate air installation, both the costs and project duration double. However, an experienced contractor with retrofitting expertise can skillfully conceal within walls, closets, and the attic, necessitating only minor incisions in walls and ceilings and leaving minimal mess.

The initial and, perhaps, the most crucial step in getting central air conditioning installed in your home is selecting the right equipment.

Heat Gain Calculation

When it comes to evaluating your home’s cooling requirements, every HVAC professional should kick off the process with a Accord Air in El Cajon, CA, load calculation. This approach is specifically designed to gauge the degree of heat gain that your household might be susceptible to. It’s a straightforward procedure that helps determine the right cooling unit size needed. If the contractor you’re considering relies solely on their experience for sizing the unit, it’s a good idea to explore other alternatives. While the geographical location plays a significant role in this calculation, there are various factors that need consideration when determining the ideal unit size. These factors include the amount of insulation in your walls and attic, the type and location of your windows and doors, as well as your home’s positioning concerning the sun. This calculation can also highlight the potential advantages of improving your home’s insulation. By enhancing energy efficiency, you might be able to reduce the size of the air conditioner required.

Determining the Right Size for Your Central Air Conditioner

When it comes to selecting the appropriate size for your central air conditioning system in your home, it’s crucial to adhere to the following recommendations.

Determining the Correct Size:

• Your HVAC contractor will utilize a heat-gain calculation to advise you on the suitable air conditioning installation size, typically expressed in tonnage or British thermal units per hour (Btu/h). To clarify, one ton represents a specific cooling capacity per hour. But why is it of utmost importance to ensure you get the right-sized unit?
• An undersized unit will struggle to efficiently cool your living spaces, especially on scorching days. This can lead to higher operating expenses because the unit will need to run for extended periods compared to a properly sized one. Conversely, an oversized compressor can also escalate your operational costs since it consumes more electricity to operate a larger system. Additionally, an oversized unit fails to effectively dehumidify. This happens because it cools the air too rapidly, causing it to shut off before enough AC  has passed over the coils to extract the necessary moisture. Consequently, this can leave the room feeling less comfortable than the temperature indicates, often resulting in a sticky and damp environment.

Unit Categories

• To begin with, the first step is to determine the kind of HVAC system you want to buy, and there are two primary categories to consider. The “package system” combines the condenser, which is responsible for cooling the refrigerant and expelling warm air, with the fan-and-coil system that cools and circulates the AC. This unit is directly connected to the airing and somewhat resembles a large wall-mounted conditioner with airs. However, it’s important to mention that package systems are relatively uncommon.
• On the other hand, the “split system” positions the condenser unit outside the house, while the fan-and-coil system is situated indoors. These components are linked through pipes that carry refrigerant. If you have a forced furnace, these refrigerant pipes connect to a cooling coil system that is integrated into the furnace air handler.
• In certain situations, the refrigerant pipes can be directed into the existing plenum. If space limitations make this impossible, the HVAC contractor will create a separate sheet-metal plenum. When forced air is not an option, the fan-and-coil system is typically placed in the attic, from where it can distribute cool AC through air. The lengthy refrigerant pipes, which can extend for 20 to 30 feet, are cleverly concealed to resemble downspouts.
• If You Need Air Installation. When it comes to retrofitting air conditioning systems, particularly those with the fan-and-coil unit located in the attic, the primary challenge revolves around establishing the supply and return air. These airs need to connect to the ceiling registers in the rooms situated on the first and second floors below. The air responsible for delivering air to the second-floor rooms typically follows a path across the attic floor before descending between the joists, ultimately connecting to the ceiling registers. Meanwhile, the serving the first-floor rooms are directed downward through closets on the second floor, whenever it’s feasible.

What can you anticipate in terms of disruptions when air installation is necessary? 

In most cases, the integrity of wall and ceiling surfaces remains largely intact. Openings will need to be made in the ceilings of the first and second floors to accommodate the registers, and there may be minor adjustments to the floors of second-floor closets to accommodate the new airs. However, these modifications are relatively small in scale, and any resulting mess can be effectively managed.

Even if your home doesn’t currently have airwork, if you wish to enjoy more comfortable summers with the addition of air conditioning, it’s advisable to consult HVAC contractors to discuss the associated costs and methods. Selecting the right professionals and equipment ensures years of comfort, and the process is often less expensive and disruptive than one might initially assume.
