Why Regular HVAC Preventative Maintenance Is Vital in Camarillo, CA


According to Consumer Reports, over 75% of homes in America use some form of air conditioning. 90% of all new homes have central air.

An HVAC system (heating, ventilation, and air conditioning) conveniently combines all your air needs into one unit using internal ducts. HVAC systems are especially necessary for people who live Camarillo CA where temperatures fluctuate from very hot to very cold throughout the year.

Like all systems, it’s necessary to perform preventative maintenance on your HVAC system. This way, your air conditioning won’t shut off when it’s 106º F in the shade.

If you’re still not convinced preventative AC maintenance is necessary, keep reading. We’re going to help you change your mind.


What an HVAC System in Camarillo CA Does

Your HVAC system performs more duties than you think it does. Here’s what HVAC technology can do for you and your home:

  • Cools your home
  • Heats your home
  • Cleans indoor air
  • Filters indoor air
  • Regulates indoor humidity levels

You’re also guaranteed that no matter where you are in your home, your hot or cold air is evenly distributed through the ducts and vents.


HVAC System Components

While this one system is used to heat, cool, and ventilate your home, there are different equipment and principles in play in order for each component to work correctly such as:



If you have a dual fuel system, both gas and electricity is generated using this system. Otherwise, you’ll either have a furnace or a heat pump generating your heat.



The furnace is the largest piece of the HVAC system. It also uses the most energy.

Most people store their furnace in an area not commonly used. There is an igniter and burners on the furnace that heats the air.

Once the air is heated, it moves from the heat exchanger through the air ducts and into the rooms of your home.


Heat Pump

A heat pump pulls air from the outside and transfers it inside. A heat pump can also remove heat from your home when it’s warm outside.

Since heat pumps move heat rather than generating it, they’re more energy-efficient.



Ventilation is important because it doesn’t just move air but it also removes excess moisture and harmful particles. The ventilation system includes:

  • Air ducts
  • Exhaust fans
  • Filters
  • Air vents

It works by moving air from the heating or cooling appliance throughout the home using air ducts. Rectangular covers are used to direct airflow back into the cooling and heating appliances. This is necessary for the ventilator to work correctly.


Air Conditioning

Air conditioners mainly cool the air and monitor temperatures using a thermostat. However, they also help control humidity.

Most HVAC systems have part of the unit outside the home and the other part inside the home. The condenser and compressor are kept outside, while the evaporator and expansion valve are kept inside.


Benefits of Preventative Maintenance

The biggest benefit to HVAC preventative maintenance is that is will save you money. Waiting until there’s a huge problem always costs a lot more than fixing minor issues. However, there are several other benefits for investing in preventative maintenance such as:


Extend the Life of Your System

When you buy a car, you know that to keep it running for a long time, you need to put gas and oil in it. You also need regular tune-ups.

It’s the same with an HVAC system. Regular maintenance means your whole system will make your unit working well for as long as possible.


Save Energy

When your heating and cooling units aren’t performing efficiently, they’re using more energy to try to work. That means you’re spending more money to get the same result as you would if your unit was in good shape.

A technician can ensure your unit is running as efficiently and smoothly as possible. You’ll rest easy knowing you’re saving energy and money.


Avoiding Unnecessary Repairs

Small repairs are inexpensive to fix. If you avoid bi-yearly maintenance, you open yourself up to costly repairs that could have easily been avoided.

If you want your contractor to show up less, invest in proper maintenance.


Keeping Your Home Safe

If you own a gas furnace, you leave yourself vulnerable to carbon monoxide leaks. You can’t smell carbon monoxide so you won’t know there’s a problem until you either feel the nasty side effects or worse, you die.

When your technician performs his or her maintenance checks, he or she can identify potential safety risks and fix them before they pose a risk to your family.


Healthy Air

Mold and bacteria thrive in dirty HVAC systems. Whether you or someone in your family suffers from allergy problems or not, dirty bacteria-laden air isn’t healthy.

A clean filter is necessary to trap air particles and prevent any contaminated air from being pulled in from areas such as the crawl space and attic. Clean heat pumps and AC coils also help to make for a healthier environment for you and your family.


HVAC Checklist

HVAC Maintenance Checklist

You should have your HVAC system checked twice a year to ensure everything is working correctly. Here is a rundown of what to expect.


Spring/Summer Checklist

Check with your HVAC service company to ensure these items on the preventative maintenance checklist are being performed.

  • Change batteries
  • Clean or replace air filters
  • Clean condenser and evaporator coils
  • Clear drain lines to ensure there’s no standing water to cause an overflow
  • Clean drain lines to ensure proper flow and clear any clogs
  • Check refrigerant charge and to find any leaks
  • Check electrical system and all connections
  • Check blades and blowers for proper airflow
  • Check outside unit for debris
  • Check fan motor
  • Inspect worn pulleys and belts
  • Inspect the cabinet for leaks
  • Inspect ducts for dust, debris, and mold
  • Inspect cabinet door to ensure it closely securely
  • Lubricate motor bearings and all moving parts
  • Observe humidity levels
  • Replace worn belts and pulleys
  • Test thermostat and controls to ensure timer functions and temperatures are set correctly

Having a technician follow this checklist will ensure that you can stay comfortable inside despite the heat and humidity that comes from a Camarillo CA summer.


Fall/Winter Checklist

When the months begin to turn colder and drier, it’s time for another checkup. Here’s what your technician should be doing:

  • Assess gas pressure
  • Check belts and pulleys
  • Check electrical connections
  • Check blower and fan operations, adjust as needed
  • Check controls and thermostats
  • Clear drain lines and pans
  • Examine heat exchanger or heating elements
  • Examine vents and duct work
  • Inspect ignition burner assembly
  • Inspect gas furnaces for any leaks
  • Inspect heat pump
  • Lubricate bearings, motors, and other moving parts
  • Replace filters on heating equipment
  • Study the flue system and make sure it’s securely attached to the furnace

Performing this checklist will ensure you stay warm all winter long.


What You Can Do to Take Care of Your HVAC System

You don’t need to rely on a technician to take care of your HVAC system. There are preventative measures you can take as well.


Immediate Preventative Care Steps

  • Start by purchasing a high-efficiency pleated air filter
  • Next, keep an eye on the parts of your HVAC system that are kept outside
  • Make sure they’re always free of leaves, sticks, pollen, grass, or pet hair
  • Remove any drapes or furniture blocking the supply and return registers

You should always keep items at least two feet away from your outdoor AC unit as well as your heat units. Remove or cut back any bushes or other items that may be encroaching on the unit. Keep the grass around the area cut short as well.


Monthly and/or Seasonal Preventative Care Steps

  • Inspect refrigerant lines every month
  • Every 90 days replace your air filters. Replace them more often if you smoke or have pets
  • Turn off water to furnace humidifier at the beginning of summer
  • In the fall, replace the humidifier filter and turn the water back on
  • Clean the condensate drain line every 90 days. A cup of bleach poured into the drain line near the AC unit kills algae in the pipe
  • Inspect the insulation of refrigerant lines every month. Replace any insulation that is deteriorating or missing immediately

To help you remember monthly or seasonal tasks, you can set an alert on your cell phone’s calendar.


Annual Preventative Care Steps

Fortunately, you only have to perform these tasks once per year. To help you remember, pick a specific date such as April 1st where you’ll do them every year.

  • Change the battery in your carbon monoxide detector
  • Make sure the ground hasn’t lifted or lowered outside where you keep your AC unit
  • Clean your vents and registers
  • Clean condenser and evaporator coils once or twice each year

Call in your professional HVAC technician once or twice a year to perform their own maintenance checklist.
