Air Conditioner Tips

1. Set your thermostat. Your thermostat should be set between 74°F and 76°F. Every 1° lower might increase running costs by up to 15%. The smaller the difference between the indoor and outdoor temperatures, the lower your overall A/C bill will be.

2. Pre-cool your house. In the middle of summer, pre-cool your house the night before. This is very effective if your house has a high thermal mass such as brick or rock. Pre-Cooling will allow your air conditioner to work at its peek during the cool evening, saving power and wear and tear on the unit. This also allows the air conditioner unit to keep on top of the heat load as the daytime temp warms up.

3. Change your air filter. One of the easiest things to do is change your air filter at least once per month. This ensures your family is breathing clean air and that your AC system is not being overworked. This also helps keep your cooling coils from getting clogged by dirt and dust which reduces the efficiency of your unit, saving money on operating and repair costs.

4. Solar Screens. Install Solar Screens on windows that get direct afternoon sunlight. This will reduce the amount of heat in your home letting your a/c rest more frequently.

5. Reduce the amount of usage by heat generating appliances during the daytime such as stoves, ovens, hair dryers, etc.

6. Clean the coils on your outside unit with a water hose regularly. This allows more air to flow across the coils therefore letting your unit operate more efficiently. This will save money on operating and repair costs.

7. Landscaping. Majority of the heat that accumulates inside your home comes directly from the sun shining on the roof or through the windows. Plant leafy trees or other landscaping around the outside of your home to help shade the area. This could boost your air conditioners efficiency by as much as 10% according to the US Department of Energy.

8. It is pretty common for an air conditioner to freeze up. The air conditioner drain line can also freeze, backup and cause a leak. If this happens, immediately turn off your AC by switching your thermostat to fan mode. As the ice begins to melt, make sure you have proper drainage and call a professional.

9. May need to be replaced. If your air conditioner system is old, consider buying an energy efficient model. Qualified air conditioners are about 15% more efficient than standard models.

Cost of Air Conditioners

There are a variety of types and costs of air conditioning systems to keep your home comfortable. When you have an idea of the costs beforehand and what type of system you are looking for ahead of time can help you make an informed decision when making your purchase. Here’s some things to consider when choosing a unit:


Window Units

Window units are definitely the least expensive option. They can easily be installed and keep a small area cool and comfortable. The downside is they will not cool your entire home and can be less efficient to run.

Central Air Conditioners

Central air conditioning systems can keep your entire home cool and keep it at a comfortable level continuously. This is the most common system here in Southeast Texas where it’s hot, hot, hot! Central air can cost anywhere from $4,000 – to over $10,000 depending on many factors including home size, size of unit, and efficiency of system.

Ductless System

If you are considering a ductless air conditioner, it can cost more than a traditional central air system. If cost if not a concern, then this may be an option for you to look into.

Keeping up with the maintenance on your A/C system is the most important component to keeping your costs low. When your system is well maintained you can help keep away from costly repairs.

The costs of different systems will depend on how well you maintain it, unit size and electric bills. A unit may cost more initially but the benefits of the more efficient unit with lower utility bills is a factor to consider.

Why is my air conditioner freezing up?

It’s the middle of July. The temps are hitting 3 digits. The last thing in the world you would expect to see is your air conditioning frozen solid!

This is a very common problem and something you might be able to troubleshoot yourself. If not you may need to have a HVAC professional come troubleshoot your system and make the necessary repairs. If you’re dealing with a frozen A/C unit, the first thing to do it turn it off.

  • Check and make sure your fan is working correctly. If the fan isn’t blowing out air like it should, that means that the cool air is confined within the unit and is the cause of the A/C unit freezing up. This is something you need to have your HVAC professional come repair.
  • Check the refrigerant levels in you’re A/C system. If there isn’t enough coolant, the coil will become too cold and cause the unit to freeze. This is another repair that you will need a HVAC technician to take care of.
  • Replace dirty air filters! There are many reasons to keep your air filters clean. Dirty filters can impede the air flow and again cause your coil to get too cold and freeze.
  • Check your thermostat. Don’t keep your air conditioner running all night when it’s cooler out. It can cause your unit to freeze up. In some cases your thermostat could be broken and cause your AC system to run all night.

At A/C Max we fix all types of HVAC issues, including AC freeze ups. We know that the summers in Southeast Texas can be extremely hot so we can respond quickly for repairs. Your indoor comfort and our customer service experience is very important to us. Please contact us for more information on HVAC products, repairs and new equipment installations.

Why does my air conditioner smell bad?

On a really hot day the first thing you do when you get home is crank the A/C down right? When you turn your air conditioner on does your house seem to smell? This can be a problem that you don’t want to ignore! If you find yourself asking “Why does my air conditioner smell?” check out the reasons and smells below to help troubleshoot what the problem is.


1. Check your air conditioning filter. If it is dirty and clogged it may not be filtering properly and contributing to the problem. Changing your air filter may not only solve the smelly issue, but it will also help your system run more efficiently.

2. Air Conditioner System is too large for your home. So we all know that an air conditioner cools your home down but many don’t realize that it also de-humidifies your home as well. If your A/C system is too large for your home it will go through the cool cycle too quick and won’t run long enough to pull any moisture from air.

3. Drain line is clogged. If your air conditioner’s drain line is clogged, water will build up in the drain pan and can be a breeding ground for mold & mildew.

4. Coils are dirty. Your A/C blows air directly over it’s coils to cool the air. If your coils are dirty the air can pick up the strange smells from the coils themselves.

5. Problems with your air filtration system. Your filtration system removes contaminates from the air in your home. If something is wrong with this system, contaminates will not be properly removed and your home’s air can begin to smell.

Mustiness – There are a few possibilities for the source of a musty smell. First there may be mold or mildew on the condenser coil inside the unit. There could also be mold or mildew growing in the duct work, if there is a leak. No matter the source, as air flows through the vents it spreads mold through your home.

Rotten eggs – If the air coming out of your vents smells a little like rotten eggs you may have a natural gas leak. A natural gas leak is very serious and would need to call a professional out to repair.

Smoke – If it smells like something is burning, there may be a mechanical problem with the Air Conditioners fan or compressor. Turn off the unit and contact an HVAC professional immediately.

What is a “ton” of cooling for your air conditioner?

Ever wondered what a “ton” of cooling meant when talking about your A/C? Before the modern day AC systems were invented houses were cooled using large blocks of ice. When cooling systems first began being used their capacity was rated by the equivalent of the amount of ice that melted in a day. So that is where the term “ton” came from when sizing an air conditioning unit.


So now you know where that term comes from! If you want to know how many tons your system should have, or if you are wondering if you have the right size equipment – give us a call at (832) 752-4445 and we’ll be glad to help you out.




3 Ways to Lower Humidity in Your Home

Here in south Texas, it’s humid as heck! Do you have foggy window? Your skin feel clammy? Usually simple steps can make a difference. Now how do you reduce the humidity level?


  1. The first and easiest way is to ventilate your home. Most importantly the areas that create moisture. Like the bathrooms and kitchen. Remember to use your vent fans! If you don’t have any, consider having them installed.
  2. House plants increase the humidity levels in your home. Take them outside temporarily. Also try covering the exposed soil. The water evaporates if not covered.
  3. Make sure your HVAC system is inspected and maintained.It helps remove moisture from the air. An improperly functioning air conditioner will allow humidity into your house. Not to mention higher utility costs.



Why is my AC not working?

When the hot temps are here and your air conditioning unit quits working, you need it fixed quick. While it’s true that many repairs will require a professional HVAC tech to fix the issue, here’s some things to check for yourself before making that phone call.

Is the unit running, but not cooling?

First check your thermostat. Do the batteries need to be replaced? Is is set to cool, not just the fan? If there’s no problem there next take a look at your condenser. Is it dirty or airflow blocked? It may be a faulty compressor or refrigerant leak. These would be problems to have a HVAC technician address.

Not cooling enough?

If there just doesn’t appear to be adequate cooling, first try lowering the thermostat several degrees. If that doesn’t cool the house down you might have a dirty evaporator. Properly clean the evaporator then let it run several hours and see if that helps. If either of those suggestions do not work, you may have an undersized unit.

Also take into consideration how hot it is outside. If temps are 100+, your unit may not be able to keep your home 65 degrees. If you are unsure about whether or not you need to replace your air conditioning unit, check with your local HVAC professional.

Condenser not running?

If your condenser isn’t running at all, check to make sure it has power. Is there a blown fuse or tripped breaker?

When to call your HVAC expert?

If you’ve still got a problem after troubleshooting it’s time to call an HVAC contractor. Also if you’re not comfortable with any part of checking it yourself make that call. Make sure you have a basic understanding of the unit before trying any of these items.

How Does my Air Conditioning Work?

Did you know the first functioning Air Conditioner was created in 1908 by G.B. Wilson? Do you know how an air conditioner works?

You air conditioner moves hot air from inside to outside, which in turn cools your home. A/C’s blow cool air into your home by pulling the heat out of the air.

The air is cooled down by moving the air over an evaporator coil. Let’s compare this to when water evaporates from your skin and causes cooling. This evaporator coil is filled with a special liquid called refrigerant. The refrigerant changes from a liquid to a gas as it absorbs heat from the air.

The refrigerant is pumped outside of your home to another coil, the condenser. It’s called a condenser because the refrigerant condenses from a gas back to a liquid.

A compressor (pump) is used to move the refrigerant between the two coils and to change the pressure of the refrigerant so that it evaporates or condenses in the correct place.
