Tips And Tricks For Installing Your Air Conditioner

To stay cool during the hot Houston summer months, installing an air conditioner is a must. But dont fear, A local Houston air conditioning company is here to help you with your very own AC installation fore starting for you to do at home. Before you start on such an endeavor, a few things need to be taken into accounts, such as safety, airflow, and supplies.

Installing in or modifying a home in any way is going to require a permit. Make sure to receive one, or some hefty fees, or fines might be in store. Any big home project can become dangerous without a moment’s notice. A permit must be used to keep people safe in potentially unsafe working conditions, in addition to making sure that the equipment used is up to par.

Air Conditioning is a Good Thing

Installing a central air conditioning unit may save money in the long run, but there’s more to it than that. Asthma attacks tend to reduce in frequency, electronics don’t overheat as quickly, and exercising becomes a much more manageable activity.

Without AC, the home becomes a breeding ground for misery and sickness. Allergies may flare up. People get sick more, leading to sick building syndrome. Dehydration becomes more of a risk. It can even make symptoms of anxiety and depression worse!

General Safety

This is pretty self-explanatory: stay safe! Before installing the AC unit:

  • Make sure that the area is cleared out and free of debris.
  • Ensure that the site is the correct size for the AC unit, and keep all children and pets out of the way.
  • Determine the size of the AC unit.

Have safety supplies available. Items such as hard hats, non-slip shoes, and face shields are a must. Inspect them before use, making sure that there is no breakage. If there are, toss it out and get a new one.

Flammable gases are a constant danger when it comes to AC installation. There may be some live wires involved, and they have the potential to explode when they come into contact with electricity. And speaking of electricity, keep any drain hoses away from it. Failure to do so will result in a bit of a shocking experience.

Getting Started

A good first step is to head to the nearest hardware store and open up an account. Installing an AC unit is going to require some tools that aren’t available to every customer, such as vacuum pumps and refrigerant gauges. These items are usually available for rent, so there’s no need to keep them around once the whole installation process is complete.

Concerning Condensers

Those who are ripping out the old AC unit and installing a new one must be careful with the condensers. It is advised to wait until the new condenser is installed to cut the refrigerant lines. Doing so prevents the buildup of moisture, which can end up causing severe issues down the line. A completely new line may need to be installed in some cases, which ends up costing more money.

Once the old AC has been gutted and the condenser removed, DO NOT let the refrigerant flow into the air. Doing so can get someone slammed with fines upwards of $10,000. The gases within these lines can cause damage to the atmosphere.


Finding a good filter before installing the new air conditioning unit is a great way to save some money preemptively. A good filter will improve the general air quality within the home and reduce energy costs. Even better, clean filters allow for the AC unit to last a lot longer, needing fewer repairs. A good filter also means better temperature control within the home.

Reusing filters is never a good idea, even the washable ones. Old filters may cause a buildup of mold and mildew, which can blow throughout the entire house. Mold can cause breathing difficulties or even make people sick.

Air Flow

It is best to figure out the airflow pattern within the home before putting in an AC system. Optimal AC placement is yet another way to reduce the costs of running it over a hot summer, saving even more money.

Take the size of the house into account. A smaller AC unit is not going to be enough to cool down a mansion. A small home with an oversized AC unit might end up turning into a freezer. The right size unit needs to be applied to the right size house.

The usage of old AC units might seem cheaper right now, but they could end up costing hundreds, if not thousands, in the future (and that’s not counting potential hospital bills).

Inadequate ventilation allows for the buildup of carbon dioxide in the air. CO2 buildup can cause an inability to breathe, dizziness, and bad headaches. Lack of flowing air causes the house’s atmosphere to stagnate, making allergies much worse and causing general misery.

All in all, excellent ventilation equals great health, improved work, work, mood, and sleep.

Stay Cool

It is a well-known fact that summers can be brutal, and the need for an excellent air conditioning system is high. Hopefully, for homeowners who are planning on installing the unit themselves, these few tips will get them going in the right direction to saving money and lower repair costs.

Be safe and install the new air conditioning unit the right way.

Tips on How You Can Troubleshoot Your Air Conditioner

You can’t afford to have a malfunctioning AC, especially in summer or winter. If your cooling and heating unit breaks down in the middle of a hot or cold season, you may want for days for a specialist to come and fix it. Fortunately, you can diagnose and repair some hitches on your AC without having to rely on an HVAC professional service. This article offers some troubleshooting tips that will help you keep your AC running without a snag.

Are You Experiencing Uneven Cooling or Reduced Airflow?

If you are experiencing uneven cooling or reduced airflow, it is advisable to check your air filters. Dirty air filters can accelerate the wear and tear of your system. Air filters are the gatekeepers of your AC because they trap debris, dust, and other allergens, maintaining a cleaner air space. They also shield your unit’s furnace. When dirt or wreckages clogs your air filters, they may obstruct airflow into your system, reducing your unit’s efficiency levels. It can also result in the tripping of your circuit breaker or fuses. If you notice uneven cooling or reduced airflow, you should check whether your filters are blocked or not. Ensure you clean or replace them more often to prevent such problems.

Your AC Not Turning On

Wrong thermostat settings can affect your AC’s workings. Check your thermostat selector switch to be sure it is set appropriately. Ensure it is set higher than the room’s temperature for heating effects and below room temperature for cooling effects. Any variance may cause your unit not to turn on. Examine your thermostat display to check if it is powered. If not, it is advisable to replace the batteries. With a tripped circuit breaker or blown out fuse, your unit won’t startup. You may also need to check your home’s power supply. If the power supply is ineffective, your AC will not turn on. To fix such issues, turn on the circuit breaker or replace the fuse. If you have been experiencing a power outage in your home, contact your electricity provider to address the issue.

Your AC Won’t Cool as Required

If you experience this problem in your home, it is advisable to confirm if the vents in every room of your house are open. A closed vent can cause your home not to cool as expected. This is because the room with a closed vent will have warm air, which mixes with the cooled air from rooms with open vents, causing instability in your home. A leaking refrigerant line can also impact your AC’s cooling abilities. This issue may require professional attention. Moreover, improper installations are also a culprit for inefficiencies in AC cooling. If your home is fitted with the wrong system, too small, or too large, you will face cooling issues. A huge system will have a faster on and off-cycle, translating to reduced efficiency. A small system will have to overstretch, resulting in a premature breakdown. Get an expert to analyze your home’s needs and design the right system for you.

Your AC won’t Stop Running

A system that is too old or wrongly sized will be compelled to work harder or cycle faster than expected, which may cause challenges when shutting it off. A dirty filter can also prompt your AC not to turn off. It is advisable to inspect your air filters and clean them. Also, you should examine the coils on the outdoor unit and ensure they are clean. Subsequently, make sure all vents are open, and your unit’s ductwork is well-fastened. If coils, air filters, and vents are in good shape, the issue may be a malfunctioning compressor. Several hitches may lead to compressor failure, such as:

  • Electrical problems
  • Inadequate lubrication
  • Obstruction of suction lines

As a homeowner, it is advisable to hire a competent professional to address compressor failure issues.

Noisy Unit

Usual noise from your AC is an indication that your unit is not functioning as expected. A constant clicking noise is a sign that your thermostat may be faulty or about to fail. Snubbing your unit’s abnormal sounds will lead to a major breakdown in the long run. Squealing sounds indicate a misaligned or worn out belt. It can also mean your system’s fan motors or blower wheels are faulty. Grinding sounds is a sign you have a problem with your unit’s motor bearings. Popping and pinging noises should prompt you to check your ductwork for loose metal. Loose cover panels lead to rattling sounds. It is important to tighten them to eliminate this problem. Banging sounds may mean it’s time to replace your compressor. Such noises will occur when there is a broken or loose part in your compressor. Screeching noises may mean you have a refrigerant leak. It is imperative to turn off your system and contact your AC repair service. Such leaks are detrimental to your health and can harm your AC.

AC Leaking Water

Inside Leaks

This occurs when your unit’s condensate drain lines are clogged. Ensure you turn off your air conditioner to help you eliminate this problem. Use a dry or wet vacuum to unblock the clogged line. If the problem persists, contact a technician to examine your condensate pump and drain pan.

Outside Leaks

Little splashes of water under your condenser unit are expected, especially in hot and humid temperatures. It is also normal for your unit to leak water in cold weather. Any other leaks may mean you clean or replace your unit’s air filters. If that does not address the leaks, call your professional maintenance expert for assistance. Your system condensate pan may be broken, or your AC might need more refrigerant. An HVAC professional will fix these issues and get your system back to its original condition. As a homeowner, you should be ready to fix some of these problems if you want comfort in your house. You don’t have to contact an expert every time you have issues with your air conditioner. It is imperative to handle these repairs as soon as you spot an issue. However, if your unit develops problems that are beyond your capabilities, it is advisable to hire a competent technician to fix the problems.
