These machines control the weather inside your home. We have very simple hvac tips for homeowners today. We will show you exactly how to take care of this expensive equipment.

This guide is basic hvac for beginners who want to save money. You do not need to be a mechanical genius to follow these steps. A little bit of easy work prevents massive repair bills later. We will cover the easiest chores you can do yourself. You will also see when to call a trained worker for help.

Keeping Your Air Very Clean

Changing The Paper Filter

The most important job is changing your indoor air filter. This thick paper screen catches dust and pet hair safely. You must slide the old dirty screen out and put a fresh one inside. You should do this easy chore every single month. A dirty filter suffocates the motor and breaks the machine completely. Read our Furnace Filter Direction guide to see exactly how to insert the new screen.

Upgrading Your Screens

Some cheap filters only catch very large pieces of dirt. You might want to buy better screens if you have bad allergies. The EPA Air Quality Basics page shows how better filters clean your indoor air. Good filters cost a few extra dollars at the local hardware store. This small upgrade keeps the inside of your metal ducts perfectly clean. You will breathe much easier while you sleep at night.

Letting The Air Flow Free

Clearing Your Room Vents

Your machine pushes warm or cold air through metal pipes in your walls. This air comes out through metal grates on your floor or ceiling. You must never put heavy furniture on top of these floor grates. Blocking these vents makes your expensive machine work much too hard. The pressure builds up inside the metal pipes and ruins the fan motor. These are simple ac tips that save you thousands of dollars.

Opening Every Single Room

Many people close the vents in empty guest bedrooms to save money. This is a very bad idea for modern heating and cooling systems. The machine is designed to push air through the entire house evenly. Closing doors and vents confuses the system and causes massive pressure problems. You should leave all the interior doors open to let the air circulate. You will actually lower your monthly power bills by keeping everything open.

Washing The Outdoor Machine

Clearing The Yard Debris

Your outdoor machine needs plenty of empty space to breathe properly. You must cut down any tall bushes growing right next to the metal box. Rake away all the dead autumn leaves resting against the metal sides. The machine pulls massive amounts of air through its sides to work. A wall of dead leaves stops the air and overheats the internal pumps. These simple hvac tips and tricks prevent total system failure.

Rinsing The Metal Coils

You can wash the outside of the metal box using a regular garden hose. You just spray the metal sides gently to remove caked on mud and dirt. You must never use a strong pressure washer on this machine. High water pressure will bend the tiny silver metal fins completely flat. Flat fins trap the heat inside and destroy the expensive outdoor pump. Read the Energy.gov Air Conditioning guide to see how clean coils save electricity.

Calling A Professional Worker

Yearly Maintenance Checkups

This guide is great hvac for dummies but you cannot do everything yourself. You must hire a trained worker to check your system every single spring. A professional opens the metal boxes and tests all the dangerous electrical parts. They check the chemical gas levels to ensure the machine cools perfectly. Check HomeAdvisor AC Repair Costs to see local rates for yearly checkups. This yearly visit prevents sudden breakdowns on very hot summer days.

Spotting Serious Trouble

You should call a professional if you hear loud grinding noises outside. You also need help if your house stays hot while the machine runs constantly. Read our AC Fan Not Turning On guide to see what broken fan motors look like. You must never touch the colorful electrical wires inside the metal boxes. Touching these high voltage wires can give you a terrible fatal shock. Call our HVAC Services team to handle all the dangerous electrical testing safely.

FAQ

What are the most important things to know about hvac maintenance for a brand new homeowner?

The absolute most important maintenance task for any homeowner is replacing the indoor paper air filter every single month without fail. You must also ensure the outdoor metal compressor unit remains completely free of overgrown bushes and dead leaves so it can breathe easily.

How often should I call a professional technician to look at my heating and cooling system?

You should schedule a professional maintenance visit at least once every spring to prepare the cooling side and once every fall to test the heating side. The technician will safely test all the high voltage electrical components and verify that your chemical refrigerant levels are perfectly balanced.

Why does my system struggle to keep the house cool even though it runs all day long?

Your system is likely suffocating because a completely clogged air filter is blocking the massive blower motor from pulling enough air through the return vents. You might also have a slow chemical refrigerant leak that requires a licensed professional to find and repair with specialized welding tools.

Can I safely wash the dirt off my outdoor air conditioning unit using a standard garden hose?

Yes you can easily wash the exterior metal fins with a standard garden hose set to a very gentle shower spray pattern. You must never use a high pressure washing wand because the intense water stream will permanently flatten the delicate metal cooling fins.

Why is closing the air vents in empty rooms a bad idea for modern central air systems?

Modern central air systems are specifically designed to push a balanced amount of air through the entire house simultaneously. Closing individual room vents creates massive backward pressure inside the metal ductwork which forces the main blower motor to work too hard and fail prematurely.

Conclusion

Taking care of your home climate system is actually very easy. You just need to change the paper filters and keep the vents completely open. You must gently wash the outdoor box to remove dead leaves and sticky mud. These simple steps keep your expensive equipment running perfectly for many years.
