If your air conditioner starts going haywire, you'd notice some minor warning signs that may lead to a complete breakdown. If cooling is not uniform, if cycling is often done, if there is not good air circulation, or if there are unusual sounds, it is a sign of some underlying problem. In the extreme heat of the Texas summer, these issues may become more apparent. Homeowners can take care of some problems, like checking thermostats and air filters, but others can only be diagnosed by a professional. Qualified personnel should take care of electrical parts, refrigerant, motors, coils, and drainage systems. Timely HVAC service Belton TX can help you discover issues before they turn into an expensive and disruptive problem. Knowing the warning signs will help you to ensure comfort, increase reliability of your air conditioning system and make informed repair decisions.
1. Your A/C unit is blowing warm air.
If the air coming from the vents is not being adequately cooled when the AC is running, then something is wrong.
There are a number of possible reasons, which may include:
· A thermostat setting or control problem.
· Restricted airflow
· Dirty air filter(s)
· Refrigerant-related problems
· Condenser problems
· Compressor issues
· Electrical component failure
Just prior to calling for service, confirm that the thermostat is switched to cooling mode and the set temperature is lower than the indoor temperature. It's also important to see if the air filter is very dirty and if there are blocked air supply vents.
If, after performing these simple tests, the warm air continues to blow, do not guess as to what is wrong, do not change out parts, etc.
A professional will be able to identify if the issue is related to the airflow, the indoor unit, outdoor equipment, electrical components, refrigerant issues or more.
2. Your AC has suddenly started to produce weak airflow.
Place hand over a supply vent and compare the air flow with what is normal.
Do not assume that the compressor is failing if the air through the vents is appreciably less than previous.
There are several reasons why there may be a problem with the flow of air, including:
• A very dense air filter
• Any blockages at the supply or return vents
• Dirty blower components
• Restricted ductwork
• A dirty evaporator coil
• Blower motor problems
The first place is the easiest to start: the air filter. When it gets dirty, replace it as per the filter manufacturer's instructions.
If the air is not moving easily afterwards, the issue could be more serious within the system.
3. Your Air conditioner keeps switching on and off.
If your AC starts up, runs for a short period and then stops, then starts up again later, it may be a problem with the cooling coils.
That is known as short cycling.
It is normal for a cyclist to take a break. Starting and stopping a lot isn't something that you have to take for granted when you have an air conditioner.
Possible causes include:
• A dirty air filter
• Thermostat problems
• Airflow restrictions
• Refrigerant-related problems
• Equipment sizing issues
• Mechanical problems
• Electrical problems
Correct answer varies depending on cause.
A thermostat replacement for instance won't solve an airflow restriction, nor will adding refrigerant fix an incorrect-sized system.
4. New or unusual sound from your AC unit.
It is natural that air conditioners make some noise while operating. A new sound, a very loud sound or a sound that has grown louder is something to be worried about.
There are some clues to be found in different sounds:
• Grinding might occur with a motor, bearing or other moving part.
• Banging can be a sign of a loose, damaged or dislodged part.
• Hissing can be due to air escaping or, depending upon the location and equipment, a refrigerant problem.
• There are electrical or mechanical causes for buzzing.
• Normal clicking is acceptable but continued or unusual clicks should be investigated.
• If there is any screeching, it is a mechanical problem that needs to be checked.
A noise by itself isn't a diagnosis. A technician should take into account the location and timing of the sound, and what the system is currently doing.
5. The Air Conditioner Water Drains Differently than Usual
Don't ignore water around indoor air conditioners!
While moisture is removed from the indoor air through the natural process of air conditioning, it also has to flow out.
Water where it shouldn't be can be associated with:
• A clogged-up condensate drain is a common issue with air conditioners.
• A leaking drain pan is another problem that may arise.
• An electric fan pump failure
• Drainage problems
Another condition that impacts normal operation
But the question of "Why is there water?" is not really the most important.
It's also:
Where does the water in the pipes and drains come from and why doesn't it drain?
If the leak is significant and not fixed, it can lead to further damage by allowing water to be near building materials in the vicinity.
What should you do?
If significant or persistent water leakage is found, close-off the system as appropriate and schedule an inspection.
Do not enter electrical areas or make new repairs which you are unfamiliar with the equipment.
6. Your energy bill suddenly increases.
If your air conditioner is being repaired, having a high electric bill does not mean that it is. Don't assume that if you have a high electric bill that your air conditioner needs repairing.
Many factors can influence how much energy is used, such as outside temperature, thermostat settings, how many people are at home, electricity costs, and more.
But, a sudden increase at the same time of a change in cooling performance is more interesting.
For example:
Your AC is operating longer, your home is not cooling as efficiently and your electricity bills are up.
This duo is something to explore.
Some of the potential sources are:
• Restricted airflow
• Dirty coils
• Ductwork problems
• Aging equipment
• Mechanical issues
• Refrigerant-related problems
• Poor system operation
Avoid replacing your furnace immediately because of a high utility bill.
Once the diagnosis is correct it can help identify maintenance, repair or equipment overall condition and efficiency issues.
7. Some Rooms Are Much Hotter or Colder Than Others
One of the most troublesome AC issues homeowners face is uneven temperatures.
Sleeping rooms may feel cool and comfortable, with the bedrooms still getting warm, or the two rooms on one side of the house may feel different from the other.
Potential causes include:
• Ductwork restrictions
• Leaking ducts
• Poor airflow distribution
• Insufficient insulation
• Blocked vents
• Thermostat location
• Home layout
• Equipment sizing
• Air-balancing issues
This doesn't necessarily indicate that the air conditioner has failed.
For instance, a second-floor room with much afternoon sun can act differently to an interior room.
That's why replacing the AC isn't necessarily the answer
8. Your AC Sends Out Cold Air in the Summer
If your air-conditioning system smells strange, especially if it is new or continuous, it's something that should be addressed.
Musty odors
Moisture, dirty components, or other indoor air quality issues can be accompanied by a musty smell.
Odors from burning or electricity.
If a burning odor is present, it is likely a mechanical or electrical component is over heated.
When you have a problem with the electrical system, shut off the system and get it serviced.
Chemical odors
There are a number of possibilities for a chemical smell. Do not presume that all chemical odors are due to a refrigerant leak.
The best way is for the source to be identified.
The significance of the source.
Odors are not a diagnosis.
Plugging up an unusual scent doesn't do anything to solve a problem.
9. Your AC is constantly in need of repairs.
Air conditioner repair isn't an indication that it's time to replace the equipment.
But a history of multiple failures should be examined more closely.
Consider:
• How old is the system?
• How often has it needed repairs?
• What components have been replaced?
• How much is the current repair expected to cost?
• Are there any signs that the system is still maintaining the level of comfort required?
• How efficient and reliable is it?
• Are replacement components readily available?
10. A Texas Heat AC Stalls in Heat Mode.
Texas heat may unveil issues that are not known during cooler times.
During periods of extreme heat, it's normal for an air conditioner to work harder and run for longer periods.
Just because something is that way doesn't necessarily indicate that something is wrong.
When it is not possible to achieve acceptable indoor comfort in the system on a regular basis or other symptoms occur as well.
Watch for:
• Excessive heat in rooms not used.
• The system that operates nearly all the time but does not provide comfort.
• Increasingly weak airflow
• Uneven temperatures
• Unusual noises
• Water leakage
• Repeated shutdowns
• Declining cooling performance
A professional will be able to determine if the problem is due to equipment capacity, airflow, ductwork, maintenance, insulation, controls or something else
Regular AC maintenance can help in the following ways:
A regular checkup will not prevent air conditioners from breaking down.
However, it can also give the chance to find out if there are developing problems and/or maintenance requirements that need to be addressed before they get worse.
This will vary depending on the system, but will involve checking:
• Filters
• Coils
• Condensate drainage
• Electrical components
• Blower operation
• Airflow
• Thermostat operation
• Outdoor equipment
• Overall system performance
Follow the equipment manufacturer's recommendations for maintenance.
It can also be a good chance for Texas homeowners to check the system before the heaviest period of the summer so they can get a good idea of what's wrong before the system is in heavy demand.
What is the life span of an air conditioner?
Not all air conditioners have a definite life span.
The life of the system depends on the following aspects:
• Equipment quality
• Installation quality
• Operating conditions
• Climate
• Maintenance
• Usage
• System sizing
• Repair history
Therefore, the age should only be considered one criterion and not as an overall indication for replacement.
In some cases, a well-maintained system can continue to operate in a satisfactory manner, and in other cases, the system may have serious problems early on as a result of installation, operating, or maintenance conditions.
Consider all the facts and not just age when deciding on replacement.
Find a Reliable HVAC Contractor
If you have a problem with your AC that you haven't encountered before, the diagnosis is as important as the repair.
Whenever you are considering approving any extensive work, you should ask:
• What did you find?
• What caused the problem?
• What was your diagnosis for this?
• What is the repair that you are suggesting?
• Are there other reasonable options?
• What does the estimate include?
• Which warranty is given for the work?
• When replacement is suggested why is repair not suitable?
A trustworthy professional ought to be able to explain the problem as you comprehend it.
If you don't need to agree to a recommendation just because it's been worded in terms of technical jargon, then it's not a recommendation you should accept.
Frequently Asked Questions
• When should I call in the professionals for my AC?
If warm air is present, airflow changes are drastic, the refrigerator cycles too quickly, water is dripping, efficiency is dropping, the refrigerator is making unusual sounds, the cooling is not equal, strange odors are present, or the refrigerator is causing repeated repairs, it should be professionally evaluated.
• My AC is running but it's not cooling, why?
There can be various reasons, such as restriction in airflow, thermostat, dirty parts, issues with the refrigerant, mechanical and electrical troubles. The symptom alone isn't enough to identify the exact cause.
• Why is my air conditioner cycling on and off?
There are many reasons for frequent cycling, including airflow restrictions, thermostat issues, equipment sizing, refrigerant-related issues or other mechanical problems. A professional diagnosis can determine the actual cause.
• Should I repair or replace my air conditioner?
Think of the age, condition, repair history, reliability, efficiency and extent and cost of proposed repairs to the system. A professional analysis can assist you to compare options.
• Is there room for personal trouble shooting of the AC?
Simple maintenance tasks like checking the thermostat, the filter, vents and any obvious obstructions outside can be done safely. Refrigerant, complex mechanical and electrical work should be performed by a qualified professional.
• Why is my air conditioner bill up so much?
Household consumption and weather can drive up energy use. When this increase happens along with a drop in cooling efficiency or significantly longer operating times, the system should be professionally assessed.
• Does my ac unit need to be running all the time in the hot weather?
During extremely hot weather, longer run times may be experienced. When the system doesn't provide reasonable indoor comfort or other symptoms like weak airflow, strange noises or frequent shut-offs, continuous operation becomes more of a concern.
Conclusion
Your air conditioning system will often give you warning signs prior to full breakdown.
If the air temperature is warm, the airflow is weak, there is short cycling, some strange noises occur, water is found around the equipment, the energy changes in an unusual way, the temperature is not even, there are strange odors, repeated repairs are needed, or performance is dropping in extreme heat, there's a reason to look more closely.
It does not take a HVAC technician to understand these warning signs.
Do it step by step with the simplest tests that are safe for a homeowner.
