Difference Between Professional vs. DIY HVAC Repairs
Changing Filter
When it comes to fixing things around the house, there are a lot of DIY projects that you can do yourself. Learning how to DIY simple tasks saves you both time and money. On the same token, trying to repair a heating or air conditioning issue without the expertise or knowledge of a HVAC professional isn’t a good idea. Keeping your heating and air conditioning unit running at peak performance means knowing which repairs you can tackle on your own and which ones you need to leave to professional.


If you're handy around, you may have already considered how you can service your heating and air conditioning unit. Below are a few of the most common DIY services most homeowners can do on their own.

Change the Filter

The easiest and most affordable way you can extend the life of your unit is by keeping the air filter clean. Swapping out the air filter every couple of months before it gets clogged also improves indoor air quality. If you have pets, you might need to change the filter once a month.

Clean the Outside Unit

In addition to keeping the air filter clean, you can also make sure that the outside unit is free of debris. Keep trees, shrubs and other types of vegetation at least two feet from the unit. Routinely inspect that nothing is caught in the fan blades as well. This is particularly important after a storm. However, make sure the unit is turned prior to inspection.

Replace Insulation

If the insulation inside your home is old and needs replaced, your monthly electric bills will reflect it. Replacing the insulation is a quick and easy DIY job most homeowners can do. You can also seal and cracks you see around windows and doors as well.

When to Call a Professional

Simple jobs like the ones mentioned above can save you money, however, it’s important to know when you need the help of a HVAC professional.

Seasonal Maintenance

You should always schedule regular maintenance, preferably with the change of seasons. Annual inspection and cleaning can catch small problems before they become major repairs, which can include cracks in the condenser, leaking refrigerant and improper air flow.


Unless you are HVAC certified, it’s always best to leave repairs to the professionals. Never try to troubleshoot why your unit is blowing cold air or leaking water. Troubleshooting a problem with your HVAC unit can do more damage than good.

New Installation

Installing a new HVAC unit warrants the help of a skilled qualified HVAC professional. Together, they can determine which unit would work best in your home, help you save money and require low maintenance. If you're still not sure which heating and air conditioning tasks you should leave to a professional, we're here to help. Contact Ductworks Heating & Air Conditioning today for more information.
