DIY air conditioner repair is costly and, in most cases, complicated even for a tools savvy well-versed homeowner. There is no way around it. However, there are some less complicated issues homeowners can handle on their own. Having worked in the HVAC industry for the last five years, today, I decided to share some tips for DIY air conditioner repair and maintenance, especially for homeowners living in Dallas. Since air quality in Dallas often goes below the “good” index range, proper maintenance of the HVAC system is very crucial for Dallas residents. So, if you are living in Dallas and have a heating and air conditioning system installed in your home or office, these tips will come in handy.

10 Tips for DIY air conditioner repair in Dallas

Awesome Tricks to Maintain your Air Conditioner in the Summer

Turn off power before you start

Safety first. So, before you even start to operate on the A/C, make sure there is no electricity running through the HVAC unit.

Turn off the AC. Locate the isolator and make sure it is turned off too. Remember, even a small amount of current running through the equipment can be fatal.

Check if the air filter needs cleaning or replacement

Air filter replacement and cleaning is the simplest DIY air conditioner repair work.

Since these filters prevent dust, pollutants, and debris from entering your home, they get dirty very quickly and, in most cases, require replacement. If you are thinking of replacing yourself, make sure to buy the right size and type of air filter your unit uses. You can take out the old one to get the dimensions or call the company that installed it to know exactly what size of air filter your unit needs.

Ensure the condensate drain is clear

Condensate drain line blockage is very common, and many DIY air conditioner repair house calls are made for this particular inconvenience. A blockage on the drain line may seem insignificant, but this small drain outlet can “make or break” your indoor comfort.

A blocked drain line means there is no path for the condensation to go out, leading to an inefficient HVAC operation. That’s why make sure to clean the line when you’re operating on the unit yourself.

Garden-scaping is important

Garden and lawn scaping is not only for the ‘show’.

To ensure air gets into your outdoor unit, clearing shrubbery surrounding the unit is a must. So next time when you decide to clean your lawn or your backyard or wherever your outdoor unit is placed, make sure to clean the areas surrounding it. Also, if you are doing any DIY air conditioner repair on the outdoor unit, take few minutes to clear out the surrounding.

Clear outdoor unit surrounding

Besides garden scaping, make sure to remove any obstacles around the outdoor unit.

If you forgetfully left a crate in your backyard close to your outdoor unit, make sure to remove it from there so that your condenser or heat pump unit gets enough air to operate.

A clean airflow path

Besides clearing out your outdoor unit surroundings, ensure nothing is blocking the air from entering your home.

Any furniture or objects sitting in front of the vents can be a reason why you are not getting the produced air. So, you might not even need a DIY air conditioner repair when you’re not getting the desired comfort. All you need to do is remove the obstacles from the air path.

Check whether your indoor or outdoor unit is making any noise

After you, DIY air conditioner repair or replace the air filter, do a test run and see if your HVAC setup makes any noise.

A loose screw or untightened part can rattle inside the unit. In such an event, you’ll need to reopen the unit and tighten whatever is making noise.

Clean indoor and outdoor unit

Accumulated dust can lower air quality in your home.

Dust, collecting on the outside or indoor unit, will get into your home and compromise air quality. That’s why make sure to clean the exterior of both units when you are DIY-ing.

Ensure proper insulation and make your system more efficient

Lack of proper insulation will make your HVAC system inefficient. That’s why when you face inadequate heating or cooling and decide to do DIY air conditioner repair, check the insulation of your entire home.

If you notice a passage from which indoor air can pass outside or vice versa, ensure the leak is taken care of and the area is adequately insulated before you turn on the HVAC system.

Check for refrigerant leaks

Lastly, look and listen to your HVAC unit. See if there is any refrigerant leak.

Refrigerant leaks can cause severe problems in the future and should not be ignored. Even though the average homeowner might not have the tools to fix the leak, identifying shouldn’t be a problem.

Why should you call a professional HVAC company?

HVAC leads

It is always advised to call a Dallas AC repair service company for help when working with a sensitive and complicated appliance like your HVAC unit. There are many licensed HVAC companies in Dallas, TX, and hiring any of them instead of DIY will be a smart move.

Even though some DIY air conditioner repairs and maintenance can be handled by homeowners, it is not advised. There are two reasons behind this, the first being the availability of proper tools and replacement parts. When a professional HVAC technician comes to check on your system, he comes prepared with all the necessary tools and equipment your A/C might need. On the other hand, when you try to repair your AC unit yourself, you’ll realize you don’t have the tool to take it apart. You might try to pry open the panels with whatever you have, which might void your warranty.

Secondly, you might not know how to operate on your AC as most DIY tutorials are generalized. So, if you have an uncommon model of HVAC equipment and you try to operate on it like some other model, as seen on YouTube, you may do more damage than good. Sometimes, even the model number can’t help. For an exact model of HVAC equipment, you might have different variants and add-on, which could make DIY repair complicated. That’s why everyone working in the HVAC industry, including me, will tell you to hire an experienced heating and cooling company to handle DIY air conditioner repairs.
