What You Should Know About Central AC

Though tons of Sacramento families have air conditioning in their homes, not many people know much about their central air conditioning. Today on the blog, our HVAC Techs share all you need to know about central AC.

What You Should Know About Central AC

Though air conditioning is something that many people have in their homes, many of our customers don’t know much about these systems. Today on the blog, our Sacramento AC Replacement experts share all you need to know about central air conditioning.  

Variety of Shapes & Sizes

The first thing our Sacramento HVAC Technicians want you to know is that there is a variety of shapes and sizes. As follows, the condenser and compressor are housed in an outdoor metal cabinet, while the evaporator is housed in an indoor metal cabinet in a split-system central air conditioner. Additionally, this indoor cabinet often houses a furnace or the indoor portion of a heat pump in several split-system air conditioners. Then, the evaporator coil of the air conditioner is mounted in the furnace or heat pump’s cabinet or main supply conduit. A split-system air conditioner is the most cost-effective central air conditioner to install if your home already has a furnace but no air conditioner.

The evaporator, condenser, and compressor are all housed in one cabinet in a packaged central air conditioner, which is normally mounted on the roof or on a concrete slab next to the house’s base. Additionally, our Cooling Company Sacramento explains that small commercial buildings use this form of air conditioner. Air supply and return ducts are connected to the packaged air conditioner, which is normally installed outside, via the home’s exterior wall or roof. However, electric heating coils or a natural gas furnace are often used in packaged air conditioners. Indoors, this air conditioner and central heater combination removes the need for a separate furnace. 

Choosing or Increasing the Efficiency of Your Central Air Conditioner

Room air conditioners are inefficient compared to central air conditioners. Furthermore, they are out of the way, quiet, and simple to use. You should try to purchase an energy-efficient air conditioner and reduce the energy usage of your central air conditioner to save energy and money. Thus, if you’re thinking about installing central air conditioning in your house, the need for ductwork may be the deciding factor.

If your central air conditioner is older, you might want to consider replacing the outdoor compressor with a more modern, high-efficiency model. If you do so, make sure the new compressor is appropriately fitted to the indoor unit by consulting a local heating and cooling contractor. However, given recent improvements in refrigerants and air conditioning designs, replacing the entire system could be the better option.

The Benefits of High Efficiency Models

The best air conditioners today use 30% to 50% less energy to generate the same amount of cooling as air conditioners from the mid-1970s. Our friends over at McQuillan Bros, Saint Paul Cooling Company, explains that, even if your air conditioner is just ten years old, replacing it with a newer, more powerful model will save you 20% to 40% on cooling energy costs.

The importance of proper sizing and installation in assessing air conditioner performance cannot be overstated. A device that is too big would not be able to extract enough humidity. On the hottest days, a device that is too small would not be able to maintain a comfortable temperature. Inefficient duct installation, improper unit placement, and lack of insulation can all reduce performance.

When shopping for an air conditioner, look for one that has a high efficiency rating. The seasonal energy efficiency ratio is used to score central air conditioners (SEER). The SEER rating indicates the amount of energy required to provide a given cooling output. SEER ratings of 6 or less are common in older systems.

When purchasing an air conditioner, look for the following features:

  • For new ventilation systems, a variable speed air handler is needed.
  • A system that runs quietly.
  • A fan-only switch, which allows you to use the unit for nighttime ventilation and save money on air conditioning.
  • After a set number of operating hours, a filter check light will illuminate to remind you to check the filter.
  • An automatic-delay fan switch that switches the fan off a few minutes after the compressor shuts down.

Air Conditioner Installation and Positioning

If your air conditioner is properly installed, or if major installation issues are discovered and corrected, it will run reliably for years with only minimal routine maintenance. However, several air conditioners are improperly mounted. As a consequence, new energy-efficient air conditioners will perform nearly as poorly as inefficient older models.

Should I Repair or Replace My AC?

If your air conditioning unit breaks down, you’ll have to decide whether to fix it or replace it. This can be a challenging decision for many homeowners, which is why we are all about making your life easier here at Gilmore. Our AC replacement Sacramento company explains the main factors to help you determine whether to repair or replace your AC. Read on to learn more. 

Age of the Air Conditioning Unit

The age of your air conditioning unit should be the first factor when determining whether to fix or replace it. Is the air conditioner more than twelve years old? Typically, AC units older than twelve years should usually be replaced with newer, energy-efficient models.

As follows, this is explained by the fact that newer models are more modern. Older units have lower Seasonal Energy Efficiency Ratios than newer models. Thus, they operate less effectively. This can result in a higher energy bill for you, as your older system may be working harder to cool your home.

Our emergency air conditioning replacement Sacramento experts explain that you can also use the 5,000 rule to help you determine if that isn’t enough. This rule states that if the age of the air conditioner is greater than $5,000 and the cost of repair is greater than $5,000, the air conditioner should be replaced. If it’s less than that, the unit should be fixed.

Repairing Air Conditioning Systems

Repairing your air conditioner on a regular basis can indicate that it’s time to replace it. If your air conditioner is continually breaking down, never properly cooling your house, and still running loudly, it’s time to fix it. If important components like the compressor or condenser malfunction, our Folsom AC Company recommends replacing the unit. Keep in mind that air conditioners can work well simply by having a Sacramento AC tune-up each year. As follows, it’s natural if your air conditioner needs minor maintenance now and then. If you’re unsure, talk to your HVAC technician.

Performance of Air Conditioning Units

If your air conditioner is twelve years old or older, works constantly, fails to adequately cool your house, and causes your energy bills to be higher than they should be, it is most likely inefficient. If this is the case, Gilmore Heating, Air and Plumbing recommend removing it. We see this in every residential home, regardless of the state you are in. Our friends at McQuillan Brothers, Twin Cities AC Company, explain that newer air conditioners will save you around $200 a year on energy costs, despite their high replacement costs. In addition, the latest units provide high-efficiency features such as smart thermostat compatibility, dehumidifiers, variable-speed motors, and scroll technology.

If you’re still not ready to get rid of your old air conditioner, there are a few upgrades you can make to improve its efficiency:

  1. Install a programmable thermostat to improve overall efficiency and control. 
  2. Install a dehumidifier. This will help keep your home cool and comfortable.

Recommendations for Air Conditioning Units

Always check with a reputable residential AC company to see if your air conditioner can be fixed or if it needs to be replaced. Depending on the issue, the technician might be able to address it without the need to replace the device. However, if the issue is beyond repair, or if the device is too old or unreliable to repair, replacement might be your only choice.

 

It can be difficult to decide whether to fix or upgrade your air conditioning unit. However, you can feel more confident in your decision if you consider the unit’s age, maintenance history, and performance, as well as professional recommendations.
