Getting Your AC System Ready for Summer in San Diego

Posted on: April 18th, 2017 by Precision Temperature No Comments

Spring is in full-swing in San Diego and it’s time to get your home ready for the year ahead. Think you’re done with your spring cleaning? Think again! Your air conditioning system probably needs some TLC before it is ready to help keep you cool all summer long. Follow these steps to get your AC system ready for summer:

Clean Your Outdoor Unit and Air Filter

Your central air conditioning system has two parts: an inside system that contains the evaporator coils and an outdoor unit that houses the compressor and condenser. Learn more about these parts and how they work here. Dirt and plant debris can impede the functioning of these outdoor parts, preventing your air conditioner from operating efficiently. You should keep plants near your outdoor unit trimmed back year-round and check periodically that nothing has become overgrown. Spring is a great time to give your outdoor unit a quick rinse with the garden hose to help clear any debris that may be stuck in it.

You should also clean or replace your HVAC system’s air filter in the spring to prepare your system for the heavy use of summer. Our easy three-step guide can walk you through this.

Give Your AC A Test Run

The hottest day of summer, with San Diego’s full heat in force, is a bad time to discover that your air conditioning isn’t working properly! Warm but not sweltering spring days offer a chance to test that your AC can do its job and keep you cool.  Turn on your AC now, before you need it, and you may be glad you did come summer.

Weatherize Your Home

Insulation and air sealing are equally as useful in the summer as they are in winter. Prevent hot air from leaking in to your home and cool, air conditioned air from leaking out and both your AC system and your wallet will thank you. A professional contractor can help you with determining what type of insulation you need and where you need it, while you can probably air seal your home on your own.

Have an HVAC Professional Perform a System Inspection

One of the best ways to be sure your heating, ventilation, and air conditioning system is functioning normally is to have it inspected by a professional. These inspections can help catch any issues before they become major expenses. In addition to looking for problems, the technician can perform any needed maintenance to help get your system ready for the summer months ahead. Preventative maintenance is key to improving your air conditioning system’s efficiency and longevity, saving you money in the long run.

How Your Air Conditioner Works

Posted on: March 6th, 2017 by Precision Temperature No Comments

Air conditioning is key to many people’s comfort and health during hot San Diego summer months. Yet for all its popularity, do you know how your air conditioner works? Let’s take a look inside the ubiquitous machine.

Primary Components

  1. Refrigerant

A chemical that easily converts from a liquid to a gas and back again

  1. Evaporator

The part of the air conditioning system located inside the house, often as part of the furnace. Where heat is extracted from indoor air and introduced to the air conditioning system, making the refrigerant into a gas

  1. Compressor

Usually located outside the house. Pressurizes the refrigerant in order to allow for more efficient transfer of heat

  1. Condenser

Usually located outside the house. Dissipates heat from the refrigerant to the outside environment, returning the refrigerant to a liquid

How Does AC Work

The Cooling Process

Air conditioning cools indoor air by taking advantage of the way in which liquid absorbs heat as it converts into gas. By forcing a refrigerant to evaporate into a gas and condense back into a liquid repeatedly in a closed system, the air conditioner regulates the temperature of your home. The process works like this:

  1. Hot air flows in

Fans direct hot indoor air over evaporator coils filled with cool, liquid refrigerant. The liquid inside absorbs heat from the air and is converted into a gas.

  1. Refrigerant flows into the compressor

Having absorbed some heat from the air, the refrigerant is now a fairly cool, low-pressure gas. This gas is directed into the compressor, where it is squeezed to raise the gas’s energy and temperature.

  1. Refrigerant enters the condenser

Now a hot, high-pressure gas, the refrigerant enters the condenser. Metal fins on the condenser dissipate the heat contained in the refrigerant into the environment outside the house. The refrigerant is returned to a cool liquid state and enters the evaporator to begin the process again until your desired indoor temperature is reached.

If your air conditioning system isn’t functioning properly, you could have an issue in any one of these areas.
