When it comes to your air conditioning system, there are some things you can fix yourself, while certain issues are better left to the pros. For example, can you replace your thermostat yourself? In today’s post, we provide an answer.
Can I Replace My Thermostat Myself?
Yes, in general, replacing a thermostat is a relatively straightforward task that can be done by anyone with medium-to-advanced DIY skills. However, you should always remember to observe basic precautions, follow the instructions in your user manual, and be ready to call a pro if you need assistance.
The process of replacing a thermostat usually involves the following general steps (refer to your manual for details):
- Shut off power
- Test all wires to make sure no power is present
- Remove old thermostat
- Pay attention to the wiring (take notes and snap a photo with your phone)
- Install the new thermostat hooking the wires according to your notes
You should always be extremely careful when electricity is involved. So one of the most important things you should do when replacing your thermostat is to turn off the circuit breakers for the thermostat, furnace, and air conditioning.
Even if replacing a thermostat is a relatively simple job, there are some situations where you should consider calling an AC pro. In the next section, we’ll take a look at some of those scenarios.
When To Call a Professional
In some cases, it makes sense to call an AC pro to have your thermostat replaced. For example:
- If you’re not confident you can do it yourself. As mentioned early, electricity is no joke, so if you are not 100% confident in your ability to handle electrical stuff, don’t hesitate: call the professionals and let them take care of replacing your thermostat.
- In some cases, you might need to run a new set of wires in order to install a new thermostat. This is not as straightforward as your typical thermostat replacement job and it may require the assistance of a professional.
- You want to ensure the job is done properly. One of the upsides of calling a professional is that you get the benefit of years of experience. A pro can make sure that the thermostat replacement process goes off smoothly and may even offer some tips to keep your home comfortable. And why not? You may even schedule an HVAC inspection while you’re at it.
