With summer coming up, you might be in a position where you’re ready to replace your old air conditioning system and start fresh. We think this is a good idea, especially if your air conditioner is more than 15 years old or it is showing signs it can’t keep up with the heat the way it used to. And if you’re thinking about investing in a high-efficiency air conditioning system with features like a variable-speed fan and multi-stage compressor, we also think that’s a good idea.
But we want to caution you that simply purchasing a high-efficiency AC isn’t an automatic ticket to lower cooling bills. It might not even be a way to get sufficient cooling.
A few weeks ago, 
In other parts of the country, winter is a time when air conditioning systems shut down for months until needed again in the spring. We don’t have that kind of climate in Texas! We have plenty of colder days, but the heat can always make a return, and air conditioners need to be ready to work at any time.
We all have in our heads an ideal version of what “October” looks like. It’s filled with autumn colors and crisp leaves and pumpkins and a slight chill to the dry air. People have this idealized October in their minds wherever they live, even if the world outside their windows never looks like it. And here in Texas, we don’t necessarily get a cool, crisp October. In fact, plenty of October days can feel close to summer days, with regular temperatures in the 80s.
Last year we wrote a post about what to do about your air conditioning system 
You probably know what Texas weather is like—summer temperatures hang around for a long time, even after the official first day of fall. We started the month of September with temperatures in the high 90s. That’s serious air conditioner weather. An air conditioner can lower the temperature inside a house by a maximum of 20°F. So when you have a 96°F day, you almost have to work the AC to the maximum to get the house down to the recommended 78°F for comfort. (Try not to set the thermostat lower than this, especially in intense heat, since it not only wastes energy, it can actually lead to the evaporator coil icing over.)
We offer services for a wide range of types of 
A common and major repair problem air conditioning systems run into is leaking refrigerant. Tiny holes along the copper refrigerant lines allow the refrigerant level in the system to drop, and that puts the entire air conditioner in jeopardy. Air conditioning systems are manufactured to run a specific charge (amount) of refrigerant. If that drops, it will not only lower cooling capacity, it will eventually inflict irreparable damage to the components, concluding with a burnt-out compressor.
You may have heard about evaporative coolers as an alternative to using a conventional central air conditioning system. Evaporative coolers are popular now as small, portable units people purchase to sit on a desk and give a bit of extra cooling. But evaporative cooling is available as a way of air conditioning an entire house through a ductwork system. Using an evaporative cooler (also called a swamp cooler) offers a number of potential benefits to a home.
In the world of air conditioners, SEER ratings are just about everything. We’re sure that when you started looking into an air conditioner, you did a little research and quickly stumbled upon SEER ratings. SEER stands for Season Energy Efficiency Ratio. It’s what you use to measure how efficient an air conditioner is. Most of the time, you’d think that the higher the SEER rating the better, right? But what if this isn’t always true?
