Deciding to Seek Help For Your AC Unit

By the time you finally get into bed at night, you might not want nothing more than to watch a fun television show in your cool, air conditioned master bedroom. Unfortunately, if you are experiencing trouble with your air conditioner, you might find yourself in a stuffy, uncomfortable space instead. However, air conditioning trouble doesn't have to come as a surprise. If you can learn to recognize the signs of trouble early, you might be able to call in the professionals before things turn sour. On my blog, you will be able to read through loads of helpful information on HVAC, so that you can detect trouble before it ruins your sleep.

Ductless Mini-Splits: Why They Offer Superior Energy Efficiency


With summer in full swing, many homeowners are looking for more energy efficient alternatives to traditional air conditioning systems. Ductless, mini-split systems are quickly gaining popularity as a more efficient and effective way to cool homes and offices.

The units are called mini-splits because they are split in two parts; the outdoor compressor and indoor evaporators that are installed individually in different rooms. The system cools every room by pumping refrigerant between the evaporators and compressor, thus dissipating heat from the house and discarding it outside.

Why you should consider mini-splits

Ductless, mini-splits are very easy to install and aren't as bulky or noisy as traditional window units. Ductless systems are also ideal for areas where installation of ductwork would not be feasible, and they are thus used to condition small spaces such as small condos and enclosed patios. If you are looking to condition additions to your home such as a garages converted into living spaces, mini-splits would be much easier to install than a ducted system.

However, their main advantage over other window units or central ducted systems is their ability to save on energy bills. Here is a look at what makes mini-split AC systems more energy efficient.


A mini-split system has evaporators (also called air handlers) that can be fine-tuned independently, thus offering varying degrees of cooling or heating in different rooms. This is made possible by isolated, independently programmable thermostats in each evaporator that allow different rooms to be cooled separately to meet the user's preference.

Since the cooling in a mini-split system is focused on an individual room, no air conditioning is wasted on empty living spaces or in unoccupied rooms, translating in huge energy savings.

Zero duct losses

The whole idea of using a mini-split system is to eliminate energy losses associated with running a traditional ducted AC unit. Central air conditioners use ductwork to dissipate heat from the home to the outdoor condenser. The problem with such a system is that there are bound to be significant energy losses due to cool air leaking through worn out ducts. Heat is also lost as a result of poor insulation, especially when ducts extend to an insulated attic.

With a mini-split system, no heat or chilled air is lost via leaking or poorly insulated ducts, though a small amount of heat may be lost via the lines carrying refrigerant out to the condenser. However such energy losses are significantly lower than duct losses in traditional central systems, resulting in more efficient cooling and heating.
