Problems Caused by Low Refrigerant in an Air Conditioning System

Monday, August 6th, 2012

Having the proper refrigerant level of an air conditioning system is one of the key components to having properly cooled indoor air.   The AC specialists at Carney Plumbing, Heating & Cooling can easily diagnosis the AC problems which could be a result of low refrigerant levels get your system back up and running in no time.

Low Refrigerant Levels Mean AC Problems

One of the most common signs of low refrigerant levels is having an air conditioner that only blows warm air or one that does not sufficiently cool an entire indoor space, leaving some rooms which are warmer than others.  This is because refrigerant is what creates the cold air, and without enough of it, you can never have enough cold air.

Frost build-up or icing around the condenser coils in the outdoor unit can mean a refrigerant leak has caused low refrigerant levels.  Because ice build-up restricts air-flow, this can mean less cool air flowing into various rooms.  Low levels of refrigerant can cause coils to drop in temperature which then creates frost or ice on the coils.

An AC system that will not turn on could also be a result of low refrigerant levels.  Newer HVAC systems have built-in safety controls which detect certain changes in how internal systems function and as a safety precaution, shuts down the air conditioner in certain circumstances rather than continuing to run and further damaging other internal mechanical or electrical systems.

These are some of the main AC problems caused by low refrigerant levels.  It is important to have a professional Harleysville  air conditioning company such as Carney Plumbing, Heating & Cooling assist you with your air conditioning concerns.  Our AC technicians provide air conditioning services such as air conditioner maintenance and repair, including fixing refrigerant levels and charging refrigerant.

Why is My Central Air Conditioner Making Noise?

Monday, July 9th, 2012

A good air conditioner is a life saver in the midst of a hot and sticky summer, but just because the system makes you comfortable and makes the hottest months bearable doesn’t mean you want to hear it clanging and banging all summer. If you notice excess noise coming from your Newtown air conditioner, it might be a problem that can be fixed by your technician. Here are some common causes of excess noise from an air conditioner and what you can do to fix them.

  • Blower – The blower is a motor and fan blade assembly. If the blade touches the housing or if the motor needs a tune up, it might start to make excess noise. Loose screws, foreign objects, or a need for oiling or new parts will all cause noise problems.
  • Ductwork – If the sounds you’re hearing are in the ductwork or vents, it may be due to expansion and contraction in your ventilation system. This is normal and while it may be obnoxious, it tends not to persist during the hottest months as temperature won’t fluctuate as much.
  • Bubbling Sounds – If you hear a gurgly or bubbly noise coming from your indoor unit, it may be due to a blockage in the condensate line. The easiest solution is to have a tech clean the condensate line and check for any clogs or blockages in the system.
  • Clicking Sounds – If you hear a clicking sound, it is likely from the relay or contactor in the system. If this is the case, have a Newtown AC professional check it right away. Electrical problems are not to be taken lightly where your air conditioner is concerned.
  • Foreign Objects – Sometimes, the condenser fan will make a lot of loud noise because foreign objects get stuck in there. Sticks, leaves, toys, food from small animals – it can all get stuck in the fans and make a tremendous amount of noise. Keep the area around your condenser unit clear of debris and check it often if you hear loud noises.

Most noises from your Newtown central air conditioning unit are explainable and can be fixed relatively easily. If you cannot find the source of the noise, however, and it is only getting worse, call Carney Plumbing, Heating & Cooling before the problem grows.
