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?
