Home DIY: HVAC Troubleshooting Step by Step
If you want to make sure that you maintain a healthy HVAC system and prolong the life of your unit for as long as possible, there are some things that you should attend to immediately when they occur and some that can be tackled seasonally or annually.
It is always best practice to hire a HVAC company who have insured technicians and know how to put things right, but there are some simple maintenance tasks that you can do keep things running smoothly between scheduled visits.
Sorting out the tasks
Using a HAVC to carry out inspection and maintenance on your system is a good idea because they can do things like inspect and clean the wiring and check the mechanical aspects of your unit, which often requires skills that the average homeowner might find challenges their skills and knowledge.
This still leaves plenty of tasks that you can tackle in order to contribute to the smooth running and efficiency of your HAVC system.
To keep your HVAC in prime condition, you should consider buying a high-efficiency pleated air filter if you don’t have one already. Also ensure that AC and Heating units are kept free of any leaves, grass or pollen.
It will also help if you make regular checks to ensure that you have a clear 2 feet of space around any outdoor units, so that they function as efficiently as possible and help reduce the prospect of debris causing damage.
Monthly and annually
Although you may be using an HVAC maintenance company to perform seasonal and annual checks, there are some tasks you can carry out in line with these timings too.
Preferably on a monthly basis or at least seasonally, inspect refrigerant lines and look to replace your air filter at least every 90 days. Turn off the water supply to the furnace humidifier in the summer months and in the fall, aim to replace the humidifier filter and turn on the water.
Replace your carbon monoxide detector battery at least once a year and clean the AC condensate drain with a suitable bleach and water mixture.
Before you call the technician
If there is something wrong with your HVAC system, it is worth trying some basic DIY before you call in a professional to sort out your problem.
It might sound very basic, but if the air conditioner does not start, do check whether there is a power supply to the unit. If the central air conditioning unit stops working on a very hot day, it is worth checking whether a high-pressure limit switch has been activated. Pressing the reset button and checking the thermostat settings might just save you a call-out charge.
If the air conditioner frequently turns on and off, check to see if there is a build-up of dirt that is preventing the unit to perform properly and make sure there is no blockage to the air flowing to the condenser unit outside.
