When our AC Unit Houston technicians visit your home, they’ll thoroughly clean and inspect every component of your air conditioning system. This will allow them to detect small problems and issues before they become larger, more costly problems. This could also increase the life of your equipment.


The reason why an air conditioner would need to be vacuumed is because the refrigerant lines would need to be cleared after it has been installed or reinstalled due to repair.  What happens is that the refrigerant in the lines joins together with moisture that enters the lines and once the AC is turned back on, that moisture will freeze.  This clogs the lines and forces your unit to work much harder than it needs to in order to cool your home.  The only way to prevent this is to vacuum out the lines.

It is always best to leave this up to a trusted HVAC contractor as they have the correct equipment and able to handle hazardous materials.  If something is not working correctly with the equipment or during the process, they have the knowledge base to figure out how to troubleshoot it and solve the issue at hand.

When it comes to anything electrical, it is always recommended to allow a trained professional handle the job, though wiring your air conditioner can be a DIY project.  It is important to be aware and concern about your safety, and making sure that all the power to the unit is turned off before doing any work.

When looking for a legitimate source for a DIY wiring job on an AC unit, be sure to do your research. There are several steps to the process and making sure to follow each step accordingly can help guarantee the best results.  If anything is not wired correctly, that can cause major issues such as blowing a fuse, causing damage to parts of your system, or even yourself.  Be sure to be aware of and follow all safety needed guidelines.

Refilling, which is also known as recharging, your air conditioning unit is not generally something that is recommended as a DIY project.  It is very highly recommended to be done by a trusted and reputable HVAC contractor who not only has the needed knowledge, but also equipment to get the job done correctly.

Though it may seem like a very simple process, it can be very dangerous not only to your unit but to yourself as well, especially if it is not done properly.  The Environmental Protection Administration, or EPA, actually requires by law that in order to do this process you must have a professional certification.

When it comes to purchasing anything, whether it is a car, appliance, or some other type of high priced electronic everyone wishes to have the best.  So when it comes to either purchasing a new air conditioning system or replacing an old one, wanting the best for your money is a given.  The only thing is that unlike cell phones or cars, AC’s are different.

There are only about 6 different HVAC equipment manufacturers that all the different brands purchase parts from.  So choosing between a Carrier or Trane, if they have similar features does not make such a difference on which is better.  What makes the difference is finding a trusted and reputable HVAC contractor to install it.  If installed correctly, you will get the full potential of your system whereas if it is installed poorly, you can end up with some serious problems down the road.  So be sure to really research more on your contractor than the brand you purchase.

Purchasing Freon, or R-22 which it is known as in the air conditioning world, is being phased out.  This means that less people are actually selling it that leads to it being hard to find and the cost being high.  They have found that R-22 is harmful to our ozone and have come up with a new refrigerant, R410A, which is also known as Puron.  It is a much more environmental friendly blend that is being used in the more updated AC systems.

It is highly recommended by most trusted and reputable HVAC contractor that if you have an old system that takes the R-22 that you consider upgrading to a newer, more efficient unit that uses R410A instead.  They are saying by 2020, all units with Freon will be phased out.  So if you have an AC that runs on R-22 and find that you have a leak or some major repair needs to be done, it might be best to consider upgrading to a newer unit.

Don’t miss the chance to benefit from our limited-time offer of 0% APR on qualifying residential replacement systems. Take advantage of our special financing today and enjoy affordable monthly payments. Deciding whether to repair or replace your AC unit can be challenging. Consider a few key factors. Start with the age of your unit. Most air conditioners last 10 to 15 years with proper maintenance. If your unit is over 10 years old, the warranty has expired, you encounter frequent problems, or repair costs are high, it’s wise to invest in a new unit. However, if your AC is younger, well-maintained, and hasn’t had major issues, repairing it may be a better option. The cost of repairs is another important factor. For newer units, unless repairs exceed thousands of dollars, it’s usually more financially sensible to stick with repairs. Professionals often use the “5,000 rule” as a guideline: multiply the unit’s age by the repair cost, and if the result is over $5,000, replacement might be a better choice. Otherwise, opt for repairs for your heating and cooling system. Installing a New Air Conditioning Unit Can Save You Money Upgrading to a new air conditioner offers multiple benefits. Not only will you regain control over your home’s climate, but you can also save money on with their energy efficiency. Outdated and inefficient ACs consume more electricity, leading to higher bills and less comfort. If you’re tired of constantly adjusting the temperature without achieving the desired cooling, a new air conditioner can make a significant difference. Does ENERGY STAR Qualified Matter?

Why AC Unit Leaks Water

July 9, 2016

When your air conditioner unit goes down for any reason, there is absolute frustration.  Especially if it is the middle of the hot and humid summer here in Houston, Texas, but the frustration level can be even higher if you find that there is a leak of some kind, like one that involves water.   The indoor part of your AC unit is usually the one that a water leak can happen.  They can be rather messy and could even cause significant water damage to your home.  This type of issue can also lead to more serious problems down the road if they are not addressed.   There are some common causes that can lead to water leaks: Condensate Pump Issues – If your condensate pump is dirty or malfunctioning in some way, this can cause your AC unit to have a water leak and could potentially flood the area this part of the unit is located in.  If there is a continual leak that is not fixed, potential mildew and mold can grow and cause it to clog. Drain Line is Clogged – Having your condensate drain pipe clogged can cause overflow in your drain pan.  This is the most common of causes for water leaks and tends to be the reason for many service calls during those high summer temperatures.  Dirt, debris, algae, and more can be the cause to clog this drain line. Drain Line is Disconnected – If you find that the drain pipes were improperly installed, the fittings may not be secure on the pipes.  As time goes on, these fittings can loosen and cause the drain pipe to disconnect from the AC completely and cause it to drain somewhere else like your floor or ceiling.  There is a primary and secondary drain pipe, so […]

It is summertime in Houston, Texas area and having an air conditioning unit that keeps you and your family nice and cool is a big necessity.  So when you notice that your AC system is either acting strange or not functioning to its full potential, then one possible issue could be that your Freon is low.   Freon, which is the refrigerant that helps your entire AC function is the blood of the machine.  This refrigerant is in charge of cooling your home by absorbing the heat out of the air inside your home.  Which means that if it is low, then your unit will not properly cool your home.   If your Freon is low, it is a major problem because it can cause some serious damage to your air conditioner if it is not recharged.  There are some signs that you can keep an eye out for that can alert you to the possibility.   If you notice that the air that is blowing out of your vents or registers is lukewarm or even warm.   Your energy bills are much higher than they normally are during this time of year.  This is because your AC unit will run for longer periods of time to try and cool your home to the temperature set by your thermostat.
