3 Signs of High Discharge Pressure On AC Units in Phoenix

High discharge pressure on AC units can cause all sorts of secondary problems down the line. HVAC systems are closed environments, so any abnormalities in AC refrigerant lines can cause undesirable consequences elsewhere. High discharge pressure on AC units in Phoenix can therefore cause all sorts of problems with your AC unit, including icing on your evaporator coils, poor performance and low efficiency.

Luckily, there are several ways to tell if high discharge pressure is the issue at hand by looking for the following symptoms. Also, if any of these symptoms read like all Greek to you, remember that you can simply call a Phoenix AC repair company to take care of the diagnosing and repairs for you.

High Condensing Temperature

Your AC unit condenser is the device that causes the refrigerant to change from a gas into a liquid, venting excess heat and raising the pressure in the line ahead as a result. However, if your condensing temperature gets too hot, it can lead to excess pressure upon the evaporator intake line among other problems.

Most HVAC units in Phoenix have a convenient feature that allows you to quickly determine the temperature of the liquid refrigerant coming out of the condenser line. A pressure gauge will be located on the “high” side of the refrigeration system. Read it to determine that side of the system’s pressure, and then convert that pressure into a temperature using a conversion chart. Locate the type of refrigerant your system uses, then trace the corresponding temperature.

A high condensing temperature is one in excess of your AC system manual’s benchmarks and guidelines.

Low Evaporator Pressure and Temperature

Low evaporator pressure and temperature can both lead to problems like icing. They are also indicative of high discharge pressure on AC units in Phoenix. To determine your evaporator’s current temperature and pressure, read the gauge on the low side and convert to temperature once again using the tables provided above.

Causes for low evaporator pressure and temperature can include restricted airflow, dirty evaporator coils, a broken evaporator fan motor and a clogged condenser screen.

High Compression Ratios

Your compression ratio is the ratio of the pressure on the “high” side of the line near the condenser and the “low” side of the line near the evaporator. High compression ratios mean that there is an excess of pressure coming out of your discharge line or something causing low pressure in the evaporator line.

Measure your high side and low side gauges, and then divide the high side by the low side. Large compression ratios in excess of your owner’s manual guidelines let you know that something is awry along the line.

Fix Your Phoenix AC Unit Hassle Free with Hays

If you determined you had a problem according to one of these symptoms or other undesirable AC unit behaviors, you can always contact a Central AC repair company in Phoenix to detect the true problem and solve it—keeping you nice and cool all summer long.

Best Way to Clean Air Conditioner Coils in Your AZ Home

Now that the warmer weather is here to stay, a properly functioning air conditioning unit is a must for all homes. Keeping up your AC unit is more than just servicing damage and repairs—preventative methods like cleaning your air conditioner coils are also necessary to keep your AC running at its best and also help you avoid costly maintenance services. Find out the best way to clean air conditioner coils to keep your AC working smoothly and efficiently this summer. 

Why You Should Clean You AC Coils

 Because air conditioner coils are located in the airstream of your HVAC unit, all of the air that heats and cools your home flows through them. This is why it is so important to keep your AC coils clean because, if not, it will affect your home’s heating and cooling system. If your AC coils are dirty, they can greatly reduce the cooling efficiency in your home and can even lead you to believe you need a new AC unit altogether. Dirty coils also restrict air flow which causes the unit to work longer and more frequently. This will, in turn, lead to higher energy costs and more difficulty to heat and cool your home.

Even more, dirty AC coils can cause dust, mold and mildew to contaminate your home’s air. This can be a serious health risk to you, your loved ones and your pets. However, when the AC coils are cleaned periodically, all of this can be avoided. Your home’s air quality will remain high, and you will increase HVAC energy efficiency. Your AC unit will also last for years longer because the motors will not be overworked from the dirty coils. Overall, keeping your AC coils will save you much more money in the long run not only in preventing repair costs but also saving you a great deal on energy costs. 

When to Call the Pros

 If you notice that your AC unit isn’t running at full levels, it is very possible that your AC coils need cleaning. Hiring a professional to clean the coils will ensure that the job is done correctly and efficiently. For your Arizona home, Hays Cooling & Heating is the best way to clean air conditioner coils and is available at your convenience. This Phoenix AC maintenance company provides all kinds of HVAC unit services, from routine maintenance on existing units to replacing or installing new ones. You can get the best service and cleaning for your AC coils with the professionals at Hays Cooling & Heating. 

DIY to Save Time and Money

If you are the type that likes to get your hands dirty, you can also clean your own AC coils with no trouble. Cleaning AC unit coils by yourself can save you time and money! Before you start, be sure to disconnect the power from the AC unit to avoid any shocks or injuries. When cleaning, use an old rag or whisk broom and shop vacuum to adequately remove dust and dirt buildup. If the dirt is really hard to remove, use biodegradable foam cleaner mixed with water to fully remove all grime and dirt. When you are done cleaning the unit, be sure to rinse away any cleaning products and foams used to clean the coils. Or, to save yourself the trouble, call us for AC coil cleaning in Phoenix.

Is My Phoenix Home AC Unit Expansion Valve On the Fritz?

With summer quickly approaching, are you nervous about the state of your Phoenix central AC system? You want to be sure to have it in excellent working order before the hot months set in, or you could be facing even bigger issues. This is especially important for those of us living in Phoenix and its surrounding areas—we use our air conditioners for most months of the year. If your air conditioner isn’t blowing cold air, there may be something wrong with your Phoenix home AC unit expansion valve.

AC Won’t Blow Cold Air

 If your home feels warmer than it should, but your air conditioner is running, it’s likely that it isn’t blowing cold air. There are a number of factors that could be causing this. For example, your unit could be running low on coolant, or there’s perhaps something wrong with either the condenser or compressor in your expansion valve. Whatever the problem may be, your certified technician will be able to get your unit cooling your home again in no time.

AC is Worn Out

 If your air conditioning is worn out, the first thing you should do is take a deep breath. These situations are stressful, but no matter what’s wrong with your unit, an HVAC specialist will know how to fix the problem at hand and restore your Arizona home to the level of comfort you deserve. There are many possible situations that could explain why your Phoenix home AC unit expansion valve isn’t working properly, and we’ll do everything we can to fix it.

Before contacting an HVAC specialist, make sure you haven’t just blown a fuse. Your central air system should be dedicated its own circuit, and your issue may just be that you need to reset the breaker. Also try turning the power off and on! If none of these reset your air conditioning unit to start working again, it’s likely time to contact a Phoenix home air conditioning repair company.

AC Air Pressure Changes

Air pressure from your air conditioner is dependent on a properly function expansion valve. The expansion valve takes pressure from the liquid coolant in the AC unit to change its state from liquid to vapor via the unit’s evaporator. The expansion valve helps the air conditioner cool an environment not by removing heat, but instead by removing pressure.

There are complicated systems of pressure in place within an air conditioning unit that allow it to function. Thus, if the air pressure is low in one component of your unit, it will affect the other unit parts—and the unit will not effectively be able to cool your home. If your AC airflow or air pressure is low, it’s likely time for you to hire a contractor to fix internal problems in your AC unit.

Fix My Phoenix Central AC System

 There are a few things you can do to try and repair a home AC unit yourself, but if there’s something wrong with your expansion valve, it’s time to hire a contractor. You’ll be able to tell that your expansion valve isn’t working properly if your unit isn’t blowing cold air or if the airflow from your unit is low.

3 Signs You Need an Air Conditioner Refrigerant Recharge

With summer just around the corner, there is no better time than now to have your HVAC unit serviced, especially in this Arizona heat. If you suspect that your AC is not working at its best, that does not necessarily mean it is time to get a new one, but you do need to have your unit checked out. Often times, your unit can be restored with a simple repair like an air conditioner refrigerant recharge instead of it being completely replaced. Check out these three signs to look out for to know if you need an air conditioner refrigerant recharge to keep you cool this summer.

If Your Thermostat is Malfunctioning

One sign to look out for to know if you need a home AC refrigerant recharge is if the thermostat is not working properly. Checking your thermostat is the best way to detect this. If it seems to be malfunctioning, reset the thermostat first to see if that solves the problem. There are two different ways you can reset your thermostat. The first way is to simply reset it at the power source or flip the breaker off and on. Another way to reset the system is by first setting the thermostat to around 85 degrees. Keep it at this temperature for about 30 minutes and then lower the thermostat to around 60 degrees and wait for the system to come back on.

If your home begins to cool again, then a reset is all you needed. If that does not work, it is possible that your unit needs recharging. A broken thermostat does not always mean that you need to recharge your system, so it is best to consult a specialist like the professionals at an HVAC maintenance company in Phoenix to properly diagnose the problem.

Are Your Vents Blowing Properly?

 Another sign to look for and be aware of in your Arizona home is if your ventilation properly flowing. When your AC needs charging, the first thing it will do is blow out warm or room temperature air. You can simply check this by placing your hand in front of a vent for about 15 minutes to make sure the warm air is not just residual air coming out of the vent system. If after 15 minutes you notice that the temperature of the air coming out is not what matches the thermostat reading or is not how it should be, then it may be time to have your refrigerant recharged.

Frost in the Summertime

 Frost buildup and frozen components inside your HVAC is a sure-fire sign of a coolant leak and requires service immediately. If handled inappropriately, coolants can be very harmful, so it is best to contact a professional when this is the sign of a refrigerant recharge. If you notice buildup around motors, tubes and other parts of your HVAC system, it is definitely time to have your unit serviced.

Keep cool this summer with a full functioning HVAC system by having your refrigerant recharged. Find out how air conditioner refrigerant recharge services can get your AC unit running smoothly again in your Arizona home.

What Causes HVAC High Suction Pressure in Phoenix Homes?

Why Is My Touchscreen Thermostat Not Working?

3 Reasons Phoenix Air Conditioner Short-Cycling Occurs

Read the full story at: http://hayscoolingandheating.com/air-conditioner-refrigerant-recharge/

What Causes HVAC High Suction Pressure in Phoenix Homes?

Summertime in Phoenix is not something to be messed with. With temperature highs averaging in the triple digits for months on end, air conditioning is vital for basically any Arizona indoor space. Your home AC unit needs to be functioning properly not just for your family’s comfort, but for their safety as well.

There are many issues that may arise that cause an air conditioner to stop working effectively. One such issue is HVAC high suction pressure in Phoenix, but what causes high suction pressure in your air conditioner?

Dirty Condenser Oil

 Condenser oil will get dirty if there is a leak in the oil separator. Grit in the condenser oil may cause the needle valve to get stuck partway open, causing the pressures on either side of the compressor’s crankcase to be off.

Excess Refrigerant

 Your high suction pressure may also be a result of excess coolant, or refrigerant, in your AC unit. Proper refrigerant levels are vital for the proper functioning of any AC unit; your specialist will be able to safely remove the necessary amount of refrigerant to restore your air conditioner to proper working order.

Bad Compressor Valves

 Leady compressor valves will likely cause high suction pressure in your Phoenix air conditioner. They may start leaking for a number of reasons, such as poor lubrication or sludge deposits that stop them from properly sealing. Compressor valves will leak if conditions cause them to start warping or overheating. You’ll know if your compressor valve is leaking (even internally) if you notice the following symptoms:

Discharge temperatures are high

Condensing pressures and temperatures are low

Condenser subcooling is normal to high

Superheats are normal to high

Amp draw is low

Bad Compressor Motor Windings

 There are three motor winding failures that can cause high suction pressure in your AC unit. An open winding occurs when one of the wires making up the motor winding gets separated or broken. A shorted winding occurs when the winding insulation has failed, causing electricity to flow between two parts of the winding that shouldn’t be making contact. A grounded winding is similar to a shorted winding, but in this case, the electricity is flowing between one of the wires and the compressor casing or ground. If you think your compressor motor has failed, your HVAC specialist will be able to check these windings to find the issue.

Contact a Phoenix HVAC Specialist

 Hays Cooling and Heating has been operating as a trusted HVAC system repair company in Phoenix since 2001. Whatever issue you may be having with your HVAC system, our trained team of experts is here to help. Make sure to get your Phoenix home AC working properly before those hot summer months set in so that you can spend more time enjoying the indoors and less time worrying about them.

6 Noisy Air Conditioner Compressor Sounds Not to Ignore

Read the full story at: http://hayscoolingandheating.com/hvac-high-suction-pressure-in-phoenix/

6 Noisy Air Conditioner Compressor Sounds Not to Ignore

Though some noises come with the territory of owning an AC unit, there are many sounds your air conditioner could be making that are too out of the ordinary to be ignored. While we’re just now welcoming in spring, for those experiencing a noisy air conditioner compressor, these sounds could be symptoms of a pre-existing issue in your unit that needs to be resolved right away. With the hot Phoenix summer months approaching even more quickly than usual, you don’t want to be caught without a properly functioning air conditioner.

Should you notice any of the following compressor sounds, it’s best to contact a professional air conditioning repair company in Phoenix immediately to make sure you’re set for the hot days ahead.

Hissing  

A hissing noise emanating from your air conditioner compressor could be a sign that you have a refrigerant or coolant leak somewhere within your unit. This may be accompanied by a possible bubbling noise. While a sealant may be used for a quick fix to a coolant leak, it won’t be cost effective or helpful in the long run—a Phoenix area heating and cooling company will be much better equipped to fix such a leak. 

Screaming 

If you hear a screaming noise coming from your AC unit, shut it off immediately and contact your heating and cooling specialist. The excessive internal pressure that causes these types of noises is too dangerous to keep that unit running any longer, and you definitely need the help of a professional. 

Buzzing 

Loose wiring is quite possibly the cause for your AC unit to buzz. Your air conditioning specialist will be able to effectively locate and fix this issue during the necessary AC compressor repairs. 

Clunking or Rattling

These types of noises are generally caused by loose hardware, which might require either the simplest or most complicated of fixes. While you very well may be able to quell these sounds by tightening a loose bolt, the cause may be something much more complicated, like bent internal refrigerant tubing. Either way, it’s best to have a trained professional check out the issue to make sure everything in your unit is in proper condition. 

Squealing 

A squealing noise is normal upon first installing a new unit, but if it doesn’t go away after a few seconds, it’s time to call your technician. 

Loud Clicking or Ticking

There are a few different explanations as to why you may be hearing AC unit compressor noises, such as a clicking or ticking sound. One is that debris may have fallen unexpectedly in your unit and is obtruding its normal functions. Another is that your fan screen is bent and the fan blades keep knocking against it. Your heating and cooling specialist should be able to locate the source of the sound very quickly and fix the issue.

Though the noise itself may be the only inconvenience you’re experiencing with your air conditioner, it could be indicative of a bigger problem that’s yet to come. Don’t put off getting your noisy air conditioner compressor fixed today!

Why Won’t My Central Air Conditioner Turn On in Phoenix?

Why Is My Touchscreen Thermostat Not Working?

3 Reasons Phoenix Air Conditioner Short-Cycling Occurs

Read the full story at: http://hayscoolingandheating.com/noisy-air-conditioner-compressor/

3 Reasons Phoenix Air Conditioner Short-Cycling Occurs

Is your Phoenix air conditioner turning off after only a short period of time? Are you possibly experiencing short off-times with your air conditioning unit? These are both examples of a common issue called short-cycling. Not only does this waste energy, the constant switches between on and off are terrible for the continued quality of your air conditioner.

There are many possible explanations as to why your AC unit is running but is not consistent, a.k.a. “short-cycling.” Luckily, there are many possible fixes to your Phoenix air conditioner short-cycling problem—you simply first need to determine what the cause is.

Refrigerant Leak in AC Unit 

One possible reason for your air conditioner to be short-cycling is that there is a refrigerant leak somewhere in your AC unit. A Band-Aid fix to this problem would be, of course, to keep adding refrigerant. However, this would simply be a short-term fix as you’d have to keep purchasing and adding refrigerant as your unit continues to leak; this would end up being a very costly solution in the long run.

Instead, contact an experienced Phoenix air conditioner repair company to locate and fix your refrigerant leak to ensure the longevity of your unit.

Thermostat Malfunction in AC Unit

Your AC unit short-cycling may be thanks to a faulty thermostat; perhaps your thermostat is not doing its job by failing to tell the unit the proper times to turn off and on. While it is possible this is an AC thermostat malfunction—it is reading temperatures incorrectly and thus in need of replacement—this issue could also be due to the positioning of the thermostat within your home. Placing it underneath a draft or in direct sunlight will undoubtedly affect its ability to read temperatures correctly.

If an issue with the thermostat is the case, your air conditioner repair specialist will be able to quickly determine whether it needs to be replaced or simply moved.

Oversized AC Unit

Lastly, a simple cause for your AC unit short-cycling may be that your unit is simply too big for the room it’s meant to cool. An easy way to tell if this is the root of your problem is to think back to how long your unit has been short-cycling. Have on or off cycles been less than five minutes since you first installed the unit? If so, it’s entirely possible that you’re using a unit that is too big.

There are plenty of online resources to help determine whether your AC unit is the proper size for your space, but your best bet is still to have a repairman come examine the unit in person. They can also be of assistance if you need to install a smaller unit.

AC unit repairs can become costly, but they will be even more so if they’re put off for the future. If you are experiencing air conditioner short-cycling, don’t wait to contact a Phoenix-area specialist. It will both save you money in the long run and get your home’s climate back under control.
