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.

When Is It Time to Upgrade Your Air Conditioner?

So your air conditioner has served you well for many years now, but it’s beginning to show possible signs of wear and require more repairs. Is it taking longer to cool your house down? Trouble maintaining temperature? These are some signs that it might be time for you to consider upgrading your HVAC system.

When you decide to upgrade your air conditioner, there are a multitude of benefits to consider. Even if your current A/C seems to runs fine, investing in a newer, energy efficient model could save you a sizable amount on utility bills.

Prepare your air conditioner for summer


You can get a head start on the summer heat by preparing your air conditioner this spring. Here’s a few items to check through to help reduce costs and prevent your a/c from breaking down.

  • Check your attic insulation

Having your home properly insulated can reduce your summer utility bills by helping keep your cold air in your home. Many homes have been built with inadequate insulation in your attic. You should have a insulation rating of R30 or R60, which is a minimum of 10-12 inches.

Similar to dirty air filters, obstructions around your outdoor unit can cause restriction of airflow, causing increased workload and a decrease in efficiency. Clean around the unit removing any weeds or grass and trimming shrubs or bushes nearby.

  • Check the drain line

When your air conditioner is functioning normally, it will create excess moisture that needs to be drained from your home. It’s always a good idea to check your drain line and make sure it isn’t clogged. When your a/c is running check for a small amount of water dripping from the line. It shouldn’t be very much water, but of you don’t see any water at all you may have a problem.

  • Get a tune up from your HVAC professional

We recommend an annual check-up on your air conditioning system. The spring time is the perfect time to have your unit checked before the heavy use during the summer heat. During a tune-up you can have your system checked for efficiency and finding any major issues before being used heavily in the summer season. Contact us today at (832) 752-4445 to schedule a visit.

How much does a new furnace/heater cost? 4 things you should know first

If you are looking a purchasing a new furnace I’m sure the first thing you are wondering is how much it will cost. Due to each homeowner’s needs and home details it is impossible to give a “one size fits all” answer. Here are a few important things to consider to help you get a better idea of how much you will be spending and what questions to expect.


  1. Your Energy Source

The first thing to consider if the type of energy source being used. Usually, electric furnaces are the least expensive, with gas then oil furnaces.

  1. Efficiency

Much like computers, furnaces are much more efficient than the huge mammoths from back in the day. This means you have so many different options when looking for a new furnace. A furnace with higher AFUE ratings will run more efficiently, and so they will cost more to purchase upfront, but end up saving you money in the long run on your utility expenses.

While you search for a new furnace, remember that a jump from a standard efficiency furnace to a high-efficiency furnace can cost anywhere between $500-$1,000+ depending on the size and energy source.

  1. Size Does Make a Difference

Having the right sized furnace can save significant amounts in energy costs over time. It can also save money upfront.

As with most things, bigger = more expensive. Have your HVAC contractor determine the correct sized unit for YOUR home. Over sized furnaces can cost more upfront and cause higher energy costs over time.

  1. Installation

Installation costs have several factors. Time it takes to install the equipment, where it is being installed, difficulty of installation, and may include new duct work. I know you may be thinking your ducts are good to go, but sometimes if your new equipment is more efficient new duct work may be necessary for proper air flow and reach the maximum efficiency of your new furnace.


When is comes to HVAC work, it varies greatly on your home and the equipment you pick.

It can be a challenge process to find the right furnace when you consider all the factors. When you begin your search for for the perfect fit for your home and your pocketbook, use this info as a starting point to make an informed decision.
