DIY HVAC is Not Advised, Leave it to the Professionals


Spending money happens as automatically as breathing or blinking.  Almost everything we do today, from work to play and everything we need to get things done like cars, food, and air conditioning all cost money to maintain.  When the opportunity presents itself to save money by alternative methods, sometimes what saves money today costs more money tomorrow.  DIY projects come with a lot of inherit risk, so we discuss why hiring professional and certified HVAC technicians is the advisable route.  Expert Air HVAC technicians Houston will save you time, patience, and money from the start.


Certification and training are required for HVAC systems and home ac units due to the level of complexity and difficulty in handling.  Don’t be fooled by YouTube tutorials, this is one unit that is not an easy feat. One malfunction can lead to total system failure, for all components work together, so you need to be knowledgeable of the entire system and on an individual part level. The gamble in handling HVAC systems when not certified or truly knowledgeable is unsafe with highly dangerous results, and that far outweighs the cost savings. Those cost savings will wither away in repair, let alone if something more dangerous were to occur, like a gas leak or a fire!


One size doesn’t fit all when it comes to AC and HVAC systems.  Every model varies, and the route to repair is not paved the same.  Having the right tool matters, and you should know that the professional tools accessible to Expert Air HVAC technicians and certified AC technicians are not what you will find in your local tool shop.


When you are outside your depth completely or whether you are rusty by a decade or so, the learning curve for DIY projects in AC repair is highly time intensive. Trial and error is not something you want to chance when it comes to ac units.  The multitude of hours you will spend researching and hopefully learning prior to risking hands-on efforts, the professionals at Expert Air can have done in no time at all.  Remember all the time you are researching; your air conditioner isn’t working.  In Texas heat, those minutes and hours are precious for overall comfort, hours of heat take even more time to cool back down, so you are doubling the time of discomfort; which only adds to your frustration.  Add to everything, you have a higher chance of malfunction and a costlier repair if you attempt to repair your home ac unit yourself. 


Some smaller care for your air conditioning unit can be done by the owner, and below we list what those are, but remember, overall maintenance needs to be left to the professionals.  You wouldn’t want to tear your car apart and rebuild it on a whim, you would get educated on all the intricate details and have hands-on training; well your HVAC system maintenance should be considered in the same concept, don’t try to maintain your unit alone, rest easy knowing Expert Air technicians are certified and experienced, let our expertise keep you comfortable.

For the usual homeowner who doesn’t possess the skill set to safely and properly repair their home ac unit, what they can do themselves include the following DIY efforts:

1.       Change the Air Filter, monthly replacement is standard, but if you have a full house and animals, you may need to do this more frequently.

2.       Don’t Block the Vents, ensure curtains and furniture don’t block your vents, for they can stop cool air from reaching your rooms.

3.       Clear Exterior Unit of Debris, trash, branches, leaves all impact the effectiveness and potentially clog the unit causing functionality issues.

4.       Trim Nearby Plants, this helps lessen likelihood of debris; keep everything clear by 18-24 inches.

5.       Hose the Unit, with your regular garden hose, lightly spray the exterior of the unit to easily remove dirt and debris accumulation.

Perks of Relying on Expert Air:

1.       Lower Utility Bills

2.       Higher Efficiency

3.       Extended Life of HVAC System

4.       Early Problem Detection

5.       Fewer Emergency Scenarios

6.       More Bang for Your Buck

Remember, never try to do a repair that is outside your skill set, especially when it comes to ac repair Houston, for you can cause more extreme damage, cause yourself injury, and/or increase the risk for a fire or gas leak. Contact Expert Air today to schedule your estimate.

Myths about HVAC Systems

Whether planning to shop or have already purchased your ac unit, being aware of the truth about HVAC myths can help you save money. Being educated about your ac system can overall help you save money and potentially avoid ac repair The Woodlands.

Below are 7 common myths regarding ac units:

  1. Myth: You save more money when you constantly run your unit rather than turning it off while gone and back on later thus re-cooling your home again
    • Truth: Off saves money and doesn’t waste energy. Turn it off if no one is home. The key is proper insulation to trap the cool air inside. Also, remember to block some heat by drawing the curtains when you leave so you can come home to a cool room.
  2. Myth: Energy efficient ac unit is all you need to save money
    • Truth: Size matters when it comes to appliances. Too much drains you financially and can be ineffective at removing the humidity that makes you feel clammy
  3. Myth: The lower the temperature setting, the faster the room is cooled
    • Truth: If your thermostat doesn’t offer a multi-setting (low/med/high), you will have one fan speed regardless of the temperature setting. Practicing this myth will get you wasted energy, higher utility bills, and a lower chill than you really want.
  4. Myth: Leaving the ceiling fan on keeps the room cool
    • Truth: Again, if no one is home, you are wasting energy and your money, turn it off if no one is home to experience it.
  5. Myth: Location of your ac unit doesn’t impact the efficiency
    • Truth: Location is a crucial key to overall ac efficiency. When the location is too close to light fixtures or electrical appliances, the ac unit gets tricked by the emitted heat surrounding them; wasted energy by false input. You get higher bills and wasted use of your ac unit, thus increasing the frequency need for ac repair The Woodlands.
  6. Myth: You only need to clean your ac unit once a year
    • Truth: Dust is constantly inevitable and it clogs filters quickly. Change your air filters every 2-3 months and sooner if the ac unit constantly runs for longer periods of time.
  7. Myth: Closing the air vents to unoccupied rooms reduces the load on your ac unit and saves you money.
    • Truth: Modern units are built to be balanced in pressure, so you intentionally closing the vents can cause an imbalance, making your HVAC system overhaul, leading to more ac repair The Woodlands and decreasing the lifespan of the unit.

A solid ac unit is essential today, but there is a lot of information surrounding the best buy as well as proper use to fully extend the lifetime of your HVAC system. If it happens that you forget the truth to the debunked myths and your habits cause the need for ac repair The Woodlands, contact Expert Air today to schedule your repairs.

Using a heat pump in order to heat and cool your home can benefit you in a number of ways, not the least of which is the fact that you can use the very same system to both heat and cool your residence. It is important to keep in mind the fact, though, that your heat pump is essentially doing twice the work of a traditional heating or cooling system. It runs during the long, hot summer season, as well as throughout the admittedly more mild winter. All of this work can lead to some serious wear and tear, which is why it is wise to schedule heat pump maintenance in Houston, TX bi-annually, rather than annually.

What Does a Heat Pump Do?

During the summer, a heat pump works in much the same manner as a regular central air conditioner. The refrigerant cycle allows it to remove heat from the air in a home, and that heat is vented to the air outside. During the winter season, the heat pump is able to reverse its operation in order to use existing heat from the air outside to warm the living space. A component called the reversing valve is integral to this process, as it allows for the reversal of the refrigerant cycle to begin with.

Why Is Maintenance Necessary?

Certain issues with a heat pump, such as a damaged fan or worn belts, can lead it to function with less efficiency, and to do so less effectively, than it otherwise would. This means that you could actually wind up paying more money for a weaker performance from your system if it is not well-maintained. We think that you deserve better than that, which is why you should have your heat pump maintained going into both the summer and the winter seasons. Furthermore, there are certain problems, such as those with the reversing valve itself, that may render your system inoperable. Don’t get caught out in the cold, or left to sweat in the summer.

Schedule your heat pump maintenance with the pros here at Expert Air Cooling And Heating.
