Green Comfort: How HVAC Contractors Help With Energy Efficiency

Good day. My name is Darryl and I work as a government researcher for the energy sector. I prepare reports which suggest ways that energy can be conserved and made cheaper. One area that is particularly under the spotlight is the effect of heating, ventilation and cooling systems on the environment. Whilst preparing my latest research report, I have been amazed by the energy efficiency that can be gained by installing the right HVAC systems. I even contacted professional HVAC contractors to upgrade, maintain and repair the systems in my own home because I learnt that older systems can use more energy without regular checks. I'm sure that there are others like me who aren't aware of the importance of choosing the right HVAC system. I hope to share a little of what I have learnt in my blog and help spread awareness. Thank you for your time.


Air Conditioning | 4 Probable Causes Behind Your Air Conditioner Failure

Air conditioning has become a vital necessity in summers thanks to soaring temperatures, so a broken down air conditioner can make your home extremely uncomfortable. If your air conditioning unit isn't working like it should or if it has broken down completely, it could be because of these probable causes. You will need a qualified HVAC contractor to tackle these problems immediately for restoring the cool comfort of your home.

Failure Of Electric Controls

The electric controls of your air conditioning unit like the fan and compressor controls can easily wear out, especially when you turn the unit off and on frequently during summers. If your air conditioning system has not been maintained in a long time, then wire and terminal corrosion could also cause the electrical controls to fail. You will need to call an HVAC repair technician to diagnose and repair the problem of failed electric controls.

Damage To The Thermostat Sensor

Most room air conditioning units have a thermostat sensor, which is set behind the unit's control panel. This sensor measures the air temperature that comes through the evaporative coil. If the thermostat sensor is damaged or knocked from its position, then your air conditioning system may start behaving erratically by constantly cycling. If you notice your thermostat sensor not performing its function, you will need to hire a qualified technician to solve your problem.

Leaks In Refrigerant

If your air conditioning unit's refrigerant levels are low, it could be because it wasn't charged properly or because of a possible refrigerant leak. If there is a leak in the system, then simply adding new refrigerant will not solve your problem. You will need to hire a technician trained to handle refrigerants to inspect and repair the leak. Once the leak is repaired, the technician will also charge your unit with the right refrigerant dose. The right refrigerant dosage that isn't undercharged or overcharged will enhance the operational efficiency of your air conditioning unit.

Improper Drainage

Many air conditioning units don't drain well thanks to improper mounting, while others face improper drainage because of clogged condensate drains. Contaminants like rust, leaves and debris can enter your air conditioning system to block the condensate drain. A blocked condensate drain will cause water to back up into your cooling unit, which will eventually overflow into your home. This will not only cause water damage to your air conditioning unit, but to your home as well. Your HVAC technician will be able to identify the source of the problem before finding a solution.

If you face any of these failures in your air conditioning unit, be sure to call an HVAC technician to take care of your problem professionally and efficiently.
