This crucial component can sustain irreparable damage in case it overheats, and the cause isn’t identified and fixed quickly. This article discusses some of the reasons given by a leading Sacramento heating and air conditioning company, Fox Family Heating and Air, to explain why your AC compressor is overheating.

Electrical Issues

Any defect in the electrical supply can cause the compressor to overheat. For example, a spike in the power supply to your Sacramento home will trigger overheating in the sensitive electrical components of the compressor. Loose connections and compromised insulation can also cause overheating in the compressor. Air conditioner repair professionals in Sacramento can fix this problem before it causes your AC to stall.

Blocked Suction Lines

The compressor of the AC may overheat in case something has constricted the refrigerant line from the indoor unit. This constriction will prevent the refrigerant from flowing at the right pressure and volume as it gets into the compressor. The compressor is therefore likely to overheat as it tries to compensate for that low pressure by sucking harder on the refrigerant.

Dirty Condenser Fins.

The fins on the condenser help to dissipate the heat carried by the refrigerant when it leaves the compressor. This heat may not be lost fully in case those fins are caked by dirt. Consequently, the refrigerant will go back to the evaporator when it isn’t as cool as it should be. The net result is that the refrigerant will be further heated by the warm air in your home and that excessively hot refrigerant will cause the compressor to overheat. Technicians at Fox Family Heating and Air warn that such a problem can cause the compressor to fail and require replacement.

Poorly Sized Refrigerant Lines

The compressor can also overheat in case the refrigerant lines are either too small or too wide. This improper sizing may cause the compressor to overheat as it works overtime to compensate and keep the refrigerant at the required pressure. Get an experienced air conditioner replacement (Sacramento) technician to inspect the AC in case it recently underwent repairs, and you suspect that the wrong refrigerant line was used.

Incorrect Cycling

Oversized or undersized AC units can also cause the compressor to overheat. For example, an undersized AC will stay on for very long to keep the temperature in your Sacramento home at the desired level. This strains all the components, especially the compressor. Overheating becomes inevitable in such situations.

Conversely, an oversized unit will start and stop more times than is usual for a correctly sized unit. These short cycle times also cause overheating because the compressor strains a lot as it is starting up. Contact a Sacramento air conditioning company for help in replacing that oversized or undersized AC.

Insufficient Refrigerant

A refrigerant leak can leave your AC with less refrigerant than is required. Inadequate recharging after air conditioner repairs can also leave the system low on refrigerant. Low refrigerant levels cause the compressor to overheat because the AC will work harder to cool your home. This situation needs to be corrected urgently before it causes a total breakdown of the compressor.

Contaminants

The compressor of your air conditioner is also likely to overheat in case contaminants, such as particulates and other gases, find their way into the refrigerant. Those contaminants are harmful because they prevent the compressor from compressing the refrigerant as it usually does. Insufficient compression strains the compressor and causes it to overheat.

Old Age

The AC may overheat due to age-related wear and tear. The increasing inefficiency of the aging air conditioner makes the compressor to overheat as it tries to keep up with the demands placed upon it during the cooling season of the year. This is particularly common in ACs which have been in use for more than ten years. Such units should be replaced instead of trying to pay attention to the compressor alone.

Although the causes of overheating in an air conditioner compressor seem unrelated, only one measure can keep most of them at bay. Proper maintenance can prevent many of the reasons why compressors overheat. Negotiate an AC service contract with the experts at Fox Family Heating and Air so that your air conditioner is kept working at its best for its entire service life.[/vc_column_text][mk_padding_divider][/vc_column_inner][vc_column_inner width=”1/6″][/vc_column_inner][/vc_row_inner][/vc_column][/mk_page_section][mk_page_section bg_color=”#ed4622″ full_width=”true” has_top_shape_divider=”true” top_shape_color=”#ffffff” top_shape_bg_color=”#ed4622″ bottom_shape_color=”#ffffff” sidebar=”sidebar-1″][vc_column width=”2/3″][mk_padding_divider][mk_fancy_title tag_name=”h3″ color=”#ed4622″ size=”36″ force_font_size=”true” size_tablet=”20″ size_phone=”15″ line_height=”90″ font_weight=”bold” txt_transform=”capitalize” margin_bottom=”0″ font_family=”Lato” font_type=”google” align=”right” drop_shadow=”true”]Need Service?

5 Preventive Measures to Keep the AC Cooling Your Sacramento Home

It is can be very inconvenient to return home to an air conditioning system which is blowing heated air instead of cooling the home during the hotter months of the year. Sacramento homeowners can take several measures to avoid the costs and inconveniences associated with such a malfunction. This article discusses some of those preventive measures.

Your HVAC System & Landscaping

One of the most common reasons why an AC may fail to cool a home is the lack of the recommended clearance around the outdoor unit. Flowers and shrubs can overgrow and block the flow of air around that external unit of the AC. Debris, such as litter from trees, can also constrict the flow of air around the unit.

This reduced airflow affects how easily the heated air from your home can be cooled before being recirculated through the ductwork. Avoid this problem by trimming any shrubs or flowers which reduce the clearance around the unit. Clean the yard frequently so that debris isn’t allowed to accumulate close to the external unit of your air conditioner. The prolonged accumulation of debris around the outdoor unit can result in high HVAC repair Sacramento bills.

Check the Filter Frequently

The air filter of your AC system can also have an adverse effect on how well the system can cool the home when the weather is hot. Clogged filters prevent air from flowing freely through the system. Consequently, the rate at which the AC cools your home will be compromised.

Different models of filters come with different recommendations about the interval of cleaning or replacing them. However, those recommended filter change or cleaning intervals can be affected by the specific conditions in your home. For example, the filter in a home with several pets may clog faster than a home without pets that shed dander.
It is therefore a good habit to set a reminder so that you can check the filter on a monthly basis. Remove that filter in accordance with the procedure stipulated in the user manual of the AC unit. Hold it against the light and clean or replace it in case you cannot see light filtering through it. This method will ensure that you can always intervene before a dirty filter causes the AC to blow heated air through your home.

Enclose the Units

The system can blow heated/warm air in case something affects a section of the electrical wiring within the indoor or outdoor unit of the air conditioner. This is particularly possible in case you have young children or pets which damage any exposed wiring.

You can protect your kids and pets from being shocked by electricity and also protect the AC from damage by enclosing the indoor and outdoor units in a protective cage or wall. This will keep curious kids and pets from the electrical wires of those components.

Use a Programmable Thermostat

Warm air coming from your AC can also circulate in your home in case some components of your HVAC system, such as the condenser, wear out due to working excessively when you set the thermostat low during the hot months of the year. The AC will keep cycling on and off frequently in a bid to maintain the desired temperature. Over time, some components will wear out and unfortunately fail.

You can avert such premature failure by installing a programmable thermostat. Set that device to change the temperature setting depending on the hours when you are away or within the home. For example, the thermostat can automatically raise its temperature setting during the hours when you are at work. The settings can then change shortly before you get back home in the evening. Our technicians always have the latest technology available to install.

Using a programmable thermostat will reduce how much work the different AC components have to do. Consequently, they will last longer and you will reduce the chance that your home will be warm yet the AC is running. Heating and air conditioning professionals in Sacramento can help during the installation of the new thermostat.

Clean Inside Your Home

The dust and other contaminants inside your home can clog the filter and ducts of your air conditioning system. Those clogs affect how freely conditioned air can flow into the different rooms of the home. Regular vacuuming and dusting can remove that dust before it takes a toll on the AC system and affects how well the home is cooled during the summer.

Keeping your home dust and dander free will go a long way towards averting many of the reasons why an air conditioning system blows warm air when it is expected to cool the home. However, the steps above are no guarantee that the system will not have any defects over time. Call an air conditioning repair technician in Sacramento and let that experts at Fox Family Heating and Air inspect and fix any issue which could have compromised the effectiveness of the AC.
