3 Things to Know About Central Air Conditioning

Understanding Central Air Conditioning Systems

Central air conditioning systems stand out for their efficiency, quiet operation, and ease of use. However, the effectiveness of these systems heavily relies on choosing the appropriate size and proper installation. Adequate insulation, strategic placement of the unit, and meticulous duct installation are crucial to maximizing the efficiency of your air conditioning system. Neglecting these factors can significantly reduce performance and increase operational costs.

Maximizing Home Comfort with Smart Air Conditioning Choices

Central air conditioners are built to last, typically offering a functional lifespan of 15 to 20 years. Manufacturers help extend this lifespan by keeping sock of replacement parts for older models. Investing in a central air conditioning system not only boosts your home’s comfort but also improves your overall indoor air experience. With the rising costs of energy, it’s crucial to choose air conditioning units that are both energy-efficient and cost-effective. Whether you’re facing urgent repair needs, planning a fresh installation, or upgrading your existing system, the upcoming advice will empower you to make decisions that optimize comfort while managing expenses wisely.

Emergency Air Conditioning Repairs

Air conditioning units do not always break down at a convenient time.  Trusted emergency AC services in Philadelphia offer 24-hour repair services for all major leading air conditioning brands.
Some of the common emergency repairs required for air conditioning systems include unresponsive unit, uneven cooling, refrigerant leaks, the air conditioning making persistent loud and strange noises, and coils getting frozen.
A certified technician will inspect all components associated with your air conditioning including insulation, ductwork, refrigerant piping, wiring, thermostat, condensate piping, filters, driers, grilles, registers, drain pipes, and evaporator coil and will suggest what repairs need to be carried out.
When expensive components like evaporator coils or compressors fail, it is better to replace the existing air conditioning unit rather than spend on extensive repairs.

Choosing The Right Central Air Conditioning System

Factors that you should take into consideration at the time of choosing the right AC equipment include:

A central air system that is too small for your home or office will not attain the desired temperature on hot days and will leave you uncomfortable.  An oversized unit will not remove humidity and will cost you more to purchase and operate.  Choose a size that caters to your requirements and is easy to install at your home or office.

Many variables such as local climate, existing installations, labor costs, equipment size, and efficiency affect the price of installation in Philadelphia. Trustworthy staff at HVAC services in Philadelphia provide clear upfront explanations and pricing information.

Central Air Equipment Warranty
Air conditioning warranties ensure that systems will last for many years.  Before deciding on purchasing a central air conditioning system, read its warranties, and understand its terms and conditions thoroughly.
Air conditioning warranties vary from manufacturer to manufacturer. It is important to register your new HVAC with manufacturer right after completion.

SEER Rating
The US Department of Energy has established minimum efficiency standards for air conditioners to reduce wastage of energy.  Every air conditioning unit is given an efficiency rating called a SEER. 
Efficiency of central air conditioning systems is expressed as Seasonal Energy-Efficiency rating or SEER.  The SEER is listed on the yellow Energy guide label posted on each air conditioning unit.
The higher the SEER, the greater the efficiency.  Higher SEER HVAC appliances tend to cost more but consume less energy over a period of time.  New systems must meet government regulated minimum guidelines for efficiency, while top efficiency models can reach a SEER of 26 or higher.

Central Air (AC) Installation and Maintenance

Only licensed HVAC technicians should perform air conditioning installations. If you install your central air unit according to codes and manufacturing guidelines and municipality codes, it should operate efficiently for many years with just minimal seasonal routine maintenance. Central AC appliances are complex and require experienced technicians for installation. Seek quotes from several locally licensed HVAC contractors with a stellar reputation and positive reviews.

The company you choose for installation can offer seasonal tune-ups to maintain your system for years to come. At the time of installing new central air conditioning and heating equipment, the HVAC contractor will:

  • Allocate adequate internal space for the installation, maintenance, and repair of the new unit.
  • Carry out the prep work before installation. In many instances, you must level the ground and place composite pads where the air conditioning unit will be set up. Composite pads are designed to withstand outdoor weather and last for the lifetime of your outdoor air conditioner.
  • Use duct sizing methodology according to the Air Conditioning Contractors of America (ACCA) Manual D.
  • Locate the condensing unit where it will not cause inconvenience to you or your neighbors. The outdoor condensing unit must have enough room around it to ensure designed air exchange through the coils.
  • Abide by state and manufacturer codes and regulations on clearances around your air conditioning unit.
  • Check and verify that the HVAC unit has the exact refrigerant charge and airflow as specified by the manufacturer.
  • Place the thermostat away from heat sources such as windows or supply registers.
  • Properly trained HVAC service managers will hire and constantly train the installation crew as an additional safety measure.

Environmental Compliance and HVAC System Maintenance

Before installing a new appliance, you must properly seal and remove old equipment containing refrigerant and oil. Releasing refrigerant into the atmosphere is unlawful. Technicians must recover old refrigerant and return it to a specialized facility. Additionally, any field technician handling refrigerants must have EPA certification.

Central air conditioning systems require regular maintenance for optimal performance. When negotiating your installation, it would be a smart move to negotiate a service plan that combines regular inspections with cleaning and defective parts replacement. You can carry out some of the maintenance on your own, like vacuuming vents, changing air filters, and clearing debris from around the condensing unit periodically. Checking the condensate drain pipe for blockages is also advisable. An HVAC service technician will ensure there are no issues and all components are functioning smoothly.
