Five most common central heating problems

Having a central heating system is no longer a luxury. For those who live in cold climates, central heating system is a necessity to survive the chilly winter cold. However, installing a quality system isn’t enough, it is also important to make sure your machine remains in good shape the whole year round. By performing regular maintenance, you will be able to avoid costly maintenance charges and a cold house during unbearable winters.

Once you’re aware of the top five problems related to central heating, you will be in perfect position to keep your home comfortable and warm. 

1. Complete heat loss - If switching on your furnace gives absolutely no response, the first thing you must do is isolate the issue – try to analyze where the problem lies. In case the system isn’t getting enough electrical power, it is best to call an electrician. Check out the pilot light. If it’s not igniting, the problem probably lies with the gas supply. You will have to call the gas supplier to tackle this issue. Also, check if the thermostat is “on” and the temperature is high enough to trigger the furnace.
2. Partial heat loss - If your furnace is giving out heat but is not operating at its best efficiency, you may have different problems going on. It is a possibility that your ductwork system is suffering from blockages or leaks. In case you have radiators, it is also possible that the radiators require bleeding to get rid of trapped air.
3. Problem with the ductwork system - Since ductwork is used extensively throughout the house, there can be several blockages due to insects or rodents. A blockage in the ductwork will normally require the services of a professional, who can analyze and fix the problem. Leaks in ductwork, leading to evasion of heat from the ducts also necessitates expert service to mend.
4. Pilot light issues - It is important for the pilot light to be lit continuously for the furnace to work efficiently. If you check the light and it is not lit, you will have to reignite it. In case you see the pilot light is set to “on”, test its strength. The flame has to be blue and strong – not weak and yellow. A weak pilot light can be extremely dangerous, leading to high levels of fatal carbon monoxide. It is best to call a professional if you ever face pilot light issues. 
5. Broken Thermostat - If you observe that your thermostat is malfunctioning, with freezing temperatures one minute and high temperatures soon after, then the thermostat is probably broken. This can cause the machine to misread the real temperature of the room and fail to run properly. It is best to call a professional to recalibrate the thermostat. In case the device is beyond repair, consider getting it replaced.

You may not be able to handle central heating problems on your own; you can certainly diagnose and get a professional to perform the repairs. Use information available over the internet to troubleshoot the furnace. It is also a good idea to call up experienced central heating maintenance providers for professional assistance. 

Water leakage in an Air-Conditioner

A fully functional air conditioner is the most desirable gadget that every household needs during summer. Sometimes even the small cooling issues can lead to big problems forcing you to compromise on cost and comfort levels during hot, sultry days.

One of the most annoying problems that you may encounter with an air conditioner is the dreaded water leak. A water seepage from the air conditioning system can be challenging indeed and difficult to diagnose. It can have multiple root causes and several solutions. This article focuses on few basic things to be considered if there is a water leak noticed in the air conditioning unit.

Main reasons for water leakage in an air-conditioner:

• Faulty pump: The most recurring cause for water leak in an air conditioner is a faulty condenser pump. The main job of this pump is to drive water out of your house. This is the water that is removed from room air by your air conditioning unit. Due to constant presence of water in the pump, it may get clogged and its capacity to pump water may get hindered. This can be tested by pouring water in the condenser pan to see if it can properly pump out excess water.
• Clogged drain line: There is a drain hole in an air conditioner for the wasted water to be driven out. Over time, dirt gets accumulated that may mix with water thereby clogging the drain pipe. Since water flow in the drain pipe becomes restricted due to congestion, water starts leaking through the main unit. By identifying the exit pipe for your drain, the water leak problem can be solved.
• Improper installation: When the main air conditioning unit and drains are not properly installed, it can cause several problems, including water leakage. A window air conditioner must be installed so that it is slightly lower at the rear than the front. This allows easy removal of water from the room towards back of the machine. If installed too low at the front, this water flows into the room rather than moving outside.
• A frozen coil: If airflow is impeded due to extensive use of the air conditioner, frost can form on the evaporator coil which eventually melts thus causing water seepage. The first thing to check in such a scenario is the air conditioner filter. If filters are clogged, air flow to the system is blocked and ice may form on the coil. Even the intake registers need to be checked to ensure that nothing is blocking the air flow into the system. Turning off the unit for a few hours every few days to allow the ice to melt may prove to be a feasible solution.
• A worn-out insulation coil: The insulation coil, at the back of the main unit is responsible for soaking up condensation that is formed on the copper wire. Due to daily wear and tear, this coil may not function properly, thereby causing water to leak from the back of the unit.

Final word of advice, do contact a reliable HVAC technician to ensure professional handling of the water leakage issue.

What To Do When The Air Conditioner Blows Warm Air?

Sultry summer days can turn worse if the air conditioner starts blowing hot air. While it is a general idea that the central air would always emit cool, refreshing air sometimes your air conditioner may just refuse to co-operate and that too when the mercury touches the maximum range. In fact, the cooling unit emitting hot air is one common problem that most households face from time to time.

Discussed below are few reasons why your air conditioner might blow warm air and how to solve this burning issue in time.

Thermostat switched to heat mode:

This is a very basic problem which air conditioner owners often overlook. It might be a very simple one that can be solved by checking whether the thermostat is switched on to the heat mode. If yes, then you need to just reverse it to the ‘cool’ mode.

Problem in Condenser and Compressor:

If you have already checked the setting of air conditioner thermostat, next is the time to take a close look at the compressor and condenser. Make sure that the outside power supply is switched on. If not then the system starts functioning from the inside handler, but you won’t realize the cooling effect.

Checking the condenser coils:

The condenser coil needs to be checked for accumulation of dirt and lint. This could seriously impact the cooling unit. In fact, condenser coils are needed to be maintained on a regular basis during summer months. Unlike changing the air filter professional assistance is needed to clean the condenser coil.

Dirty air filter:

An unclean filter can obstruct the condensing coil of your air conditioner with dust and pollutants thereby causingthe unit to freeze up. To avoid this, make sure the air filter is changed or checked every season, especially before the start of summer. A maintenance plan should be readied by consulting any renowned HVAC contractor from your locality. This would ensure proper cleaning and installation of the air conditioning unit filter.

Refrigerant problems:

Refrigerant related problems are often the outcome of compressor snags or leakage. In worst cases, cool air might stop completely. This primarily occurs due to reduced refrigerant charge. The main symptom is a deposition of ice on the exterior or the interior unit. Just a nominal repair can solve the problem, provided the compressor is in sound shape.

To-do tips:

Fixing problems of the air conditioner is not that difficult. Prompt planning beforehand and executing them sequentially are best ways to handle the issue. Preventative maintenance is suggested for the unit on a regular basis. In order to avoid serious cooling problems during summers you must schedule an annual tune up.

By keeping a check on the above mentioned factors you can easily reduce expensive repair costs. The final piece of advice which every user should follow is seeking professional assistance whenever some snag is sensed with the cooling unit. There are numerous air conditioner servicing companies ready to offer prompt services within reasonable budget. Get in touch with the right one to ensure long life of your precious air conditioner.

Common Air Conditioning Mistakes Which Should be Avoided

Rising mercury has a direct impact on air conditioner usage. The more the air conditioning unit is used, greater remain chances of the system developing snags. Awareness about common air conditioning problems certainly helps ensure optimal energy consumption and comfortable cooling. Listed below are few such common air conditioning mistakes that can easily be avoided:

1.      Skipping maintenance work

A well-maintained air conditioner always works efficiently which becomes evident from the pleasantly cool air that it spreads! Regular maintenance ensures longer life span of the air conditioner. Some work can be done at home like checking duct lines for leakage, cleaning filters and evaporator coil, etc. Never skip or ignore maintenance work. Help is always available in the form of an HVAC technician who can assist you with regular maintenance.

2.      Size misfits

Most people are of the notion that a bigger air conditioner cools better and faster. Even though it is true to an extent, an oversized air conditioner doesn’t generate uniform temperature or reduce humidity. This defeats the whole purpose of using the cooling unit in warm climates. The best option is to refer to Consumer Reports worksheet to help find the right sized air conditioner. An HVAC technician can be consulted too.

3.      Unreasonable thermostat settings

If a thermostat is set too low, then more energy is wasted. Then if it is set too high, then the air conditioner would fail to even turn on or go bust in some cases. To avoid these problems, reasonable thermostat settings are to be adopted. A programmable thermostat best serves this purpose. Another major area of concern is accidental heating up of the thermostat. This usually happens when other electrical appliances like lamps, televisions, refrigerators, etc. are placed close to the air conditioning system. The heat generated by these electronic gadgets causes the thermostat to malfunction inadvertently.

4.      Closure of unused vents and openings

Though it may seem like a good idea to prevent escaping of conditioned air outside, the efficiency of a central air conditioning system might get affected in the longer run. An HVAC expert can be consulted in this regard, especially for the summer months. Another strict no-no would be to close off any room that has a thermostat installed.

5.      Wrong placement of the cooling unit

Most people prefer relatively unused spots to install their air conditioners in homes. However, such placement only puts excess pressure on the unit. Some people choose to place the air conditioning unit behinds shrubs or plants. This hinders ventilation and leads to clogged air filters. Such minor issues ultimately result in decreased efficiency of the air conditioner. An HVAC expert usually suggests the ideal place for cooling system installation, as the east or north side of the house. This is to ensure that the air conditioner is installed in a shady spot and away from direct sunlight.

These above discussed air conditioning mistakes might sound quite simple but most households tend to forget the basic rules while installing/maintaining the unit. Rather than allowing these minor cooling mistakes take a major turn, you should get in touch with a trustworthy HVAC company for unbiased guidance and timely action.

Three Minor Problems Which Can Seriously Affect the Cooling Unit

There are quite a number of common air conditioning problems that tend to affect overall performance of the cooling unit. These minor issues lead to more drastic problems such as the unit going off completely and needing an overhaul. There can be other problems like wasted energy, rising monthly power bills, non-performance or under performance of the air conditioning unit. All these might lead to the air conditioner replacement. Therefore, it is important that these minor problems are checked regularly and taken care of immediately, to ensure efficient performance of the cooling unit.

The three common and minor problems which can severely affect your cooling unit’s performance are:

1.      Uneven and insufficient cooling

This is one of the most common problems which every air conditioner user might have experienced now and then. It may happen that the air conditioning unit fails to cool your home sufficiently or evenly. This problem is caused due to inaccurate thermostat settings. Blame it on a dead battery too. The lower a thermostat is set, higher is the energy consumed by the central air. Therefore, thermostat settings should be adjusted reasonably and this objective can be best achieved using a programmable thermostat.

Duct lines that are cracked, disconnected or not installed properly may lead to conditioned air leaking out which eventually result in uneven cooling. The condenser unit present in the exterior part of the air conditioner might get clogged with leaves and other debris leading to underperformance of the cooling system.

2.      Short Cycling

The term “Short Cycling” refers to successive switching on and off sequences of the air conditioning system. This problem occurs either from dirty and iced coils or a clogged air filter.

Dirty or iced coils result in shutting down of the cooling unit as their ability to transfer heat gets restricted with accumulation of dirt or ice. A clogged air filter results in excessive buildup of dirt and debris inside coils and hence requires immediate cleaning. A high efficiency air filter surely helps avoid the problem of short cycling altogether.

3.      Failure of the cooling unit to turn or its abrupt shut down

A tripped circuit breaker is to be blamed if the air conditioner is not switching on properly or shutting down abruptly. The circuit just needs to be reset when this issue crops up. In some cases, the cooling unit fails to turn on if the thermostat is set too high. To avoid this issue, the thermostat should be adjusted 5 degrees lower than the initial point before restarting. Reasonable thermostat settings are to be adopted thereafter.

Apart from these aforementioned issues, the motor in air handler system may burnout due to clogged air filters. This means excessive energy is needed to push cool air through duct lines, thereby leading to failure of the cooling unit and its abrupt shutting down. Thus it is even more significant to clean the air filter regularly.

Regular maintenance of a cooling unit is absolutely vital for its efficient performance. Whenever you notice any of these minor cooling problems raising their heads, do immediately get in touch with an HVAC expert for unbiased guidance and timely action.

Tips to Protect Your Air Conditioner during Hurricane

Natural disasters like cloudburst or hurricane doesn’t strike with prior notice. However, when it does, often the severity is such that it leaves many households in shambles.  Mostly electronic gadgets like home air conditioners take the maximum blow. Even after the effect of hurricane subsides, you may find the cooling unit in an unstable condition.  So, how to protect the air conditioning system from a thunderstorm’s catastrophic effect?

Take Precautionary Measures before the Storm Strikes

Start taking preventive steps before the hurricane season sets in. If you are aware of the approximate time when the storm is going to strike, then prior to that, turn on the air conditioner. Adjust the setting such that the indoor temperature turns several degrees cooler than normal level. Such a pre-cooling helps keep the home temperature comfortable for longer hours, even if power failure happens accidentally.

Should you operate the cooling unit during the hurricane?

The answer is a big No. Strictly make sure that the air conditioning unit is switched off as the cyclone strikes.  In many areas, the power supply gets interrupted during heavy storm or downpour. If the air conditioner is running at that time, it might suffer severe damage because of erratic power failures. As and when natural disaster strikes, irregular power interruptions put additional pressure on the compressor and other components of the cooling unit. Thus, you might end up changing the entire unit or some of its crucial components, once the stormy season is over.

What you should do after the tropical storm passes?

It is suggested that you turn on the cooling unit, as early as possible. Some delay might happen because of power problems, still try to operate once the power condition returns to normalcy. Keeping the unit idle for too long, means you are inviting mold to grow in the unit’s ducts and system. Your home as well as the air conditioning system has just now gone through an extreme heat and high moisture weather mayhem. This provides perfect setting for mold to thrive.

At the same time, be careful if you suspect something amiss with the central air’s operation. In case, you feel the storm’s severity has damaged an inside part of the cooling system then trying to run would make the situation even worse. Detection or evidence of any electrical smoke should be taken seriously. In such a scenario, get it immediately checked by any skilled HVAC professional.

Prepare your Air Conditioner to Ward off Storm Effect

One thing to be kept in mind is that it is not always a hurricane which harms your cooling system. Sometimes heavy wind and rain play havoc too, damaging the air conditioning unit. So after any such natural disaster, you should consider a thorough checkup of the cooling system with special stress on duct cleaning.

No matter how devastating the hurricane looks, by following these simple tips you can efficiently protect the air conditioner throughout the stormy season.

How to Make your Window Air Conditioner Burglar-proof?

With mercury rising incessantly inside skyscraper cells, air conditioner units have become an indispensable part of modern city life. A window air conditioning unit provides efficient cooling in little time. Of course being an electronic device, the risk related to a sudden break down always remains for which certain precautionary measures can be taken.

Apart from technical snags, something even worse can happen to the cooling unit. Your window air conditioner might become an easy burglary target! Homeowners, therefore have to be little more careful and adopt extra precautionary measures to make their air cooling systems burglar-proof.

External Brackets

Get a high quality external bracket for your air conditioning unit as soon as possible. These brackets provide additional support to the cooling unit while securing it well with the window. This in turn serves two purposes. Firstly, it becomes very difficult to move the air conditioner. Secondly, no one can easily break into your house by pushing the device inwards.

Corner Braces

Function wise, corner braces are almost similar to external brackets. You can still install braces to enhance security arrangement. When corner braces are attached to all four sides of the air conditioner, these help secure the device properly. Then these braces protect the surrounding wall area too thereby preventing the device from being pulled out or pushed in.

Window Locks

To prevent burglars from tampering with window frames of the sliding window you need to install high quality window locks. There are two varieties available in the market, i.e., screwed and bolted. Both types are equally effective. The lock can be used to secure frames from both sides as well as up and down. Position the locks strategically. For maximum efficiency, place them along the line where the window meets the wall.

Vent Flaps

Typically an air conditioning device is smaller in size than the window. Therefore the free area outlining the cooling machine becomes an easy target for burglars. So to make sure no one takes advantage of this free space, you can install metal or plastic vent flaps. Secure the vents tightly so that no tampering can be done.

Sensor Alarms

To prevent any burglary attempt, install miniature high sensor alarm devices. These alarms can be positioned right on top of the AC so that any attempt to move it even by smallest proportions gets detected immediately. Make sure the alarm works properly and sets off in time.

A high-pitched alarm system is preferred since this will alert you even if you are in another room. Further the high-pitch sound alerts your neighbors too in case you are not at home. Most importantly the alarm sound scares the burglar away.

In case you can’t install an alarm system, try to fake it! Attach symbols denoting an alarm system on your air conditioning unit irrespective of whether you actually have it installed or not. Sounds funny? The strategy does work in such emergencies.

Last but not the least; you can always talk to any air conditioner expert to know how to render maximum protection to your window air conditioning unit.
