Common Air Conditioning Problems

Summer is when we see frequent problems with air conditioning units due to the fact that they are operating at peak performance. During this time, units will break down, or even fail, leaving homeowners stuck with the heat. Cooling system problems should never be ignored, as keeping your home cool is very important to your home comfort.

If your system isn’t cooling, you can do a check of some simple DIY basics:

Make sure the electrical switch for the Air Conditioning is ON     ac problems blog 2

Check to make sure your filter is clean

Verify that your thermostat is set to COOL

Make sure all vents are open in your home

Close all of the windows

If you have a humidifier, make sure that it is OFF

Once you’ve taken those steps, if you are still experiencing problems, you should contact a professional.  The system could be experiencing a refrigerant leak, problems with electrical components or motors. Keep in mind, that annual maintenance of your equipment can help find problems before they shut down, or damage your system.

Benefits of Duct Cleaning

duct cleaning blog 2Indoor air pollution is now listed by the Environmental Protection  Agency as the fourth greatest environmental threat to Americans. When your heating and cooling system is running, airborne contaminants are being drawn into your duct system. Over a period of time, these harmful contaminants will eventually build up inside your air ducts.

Indoor contaminants may include dust mites, tobacco smoke, household mold, chemicals, airborne allergens, bacteria, animal dander and carbon monoxide. These contaminants are then circulated throughout your home or office and effect the health and comfort of you, your family, or your employees. Having your air ducts cleaned can help eliminate these problems. It can also reduce the amount of dusting needed, improve indoor air quality, save energy and money and extend the life of your equipment.

Can Air Conditioners Control Humidity?


Humidity control was the problem that originally spurred the need for air conditioning. Lack of humidity control in hot, humid climates, in particular, can lead to mold growth and other moisture-related problems. High indoor humidities can lead to health and comfort problems. Modern air conditioners dehumidify as they cool; you can see that by the water that drains away, but this dehumidification is incidental to their main job of controlling temperature. They cannot independently control both temperature and humidity.

What is a SEER rating?

seer rating blog pic

As with anything having to do with energy conservation SEER is probably the least understood concept, both by homeowners      and contractors. Simply put, SEER stands for Seasonal Energy Efficiency Ratio. The resulting number that is applied to an air   conditioner is called it’s SEER rating. The higher the SEER rating the more energy efficient a given air conditioner is.


Save Money with Programmable Thermostats

Most programmable thermostats are either digital, electromechanical, or some mixture of the two. Digital thermostats offer the most features in terms of multiple setback settings, overrides, and adjustments for daylight savings time, but may be difficult for some people to program.


When programming your thermostat, consider when you normally go to sleep and wake up. If you prefer to sleep at a cooler temperature during the winter, you might want to start the temperature setback a bit ahead of the time you actually go to bed. Also consider the schedules of everyone in the household. If there is a time during the day when the house is unoccupied for four hours or more, it makes sense to adjust the temperature during those periods.

What are the different types of air conditioners?

What are the different types of air conditioners?

There really are 2 main types of air conditioning systems. 

The first type is a split system.  This system would have a ground mounted condenser outside that is connected to a coil which is mounted either a furnace or an air handler.  That system would then distribute the air through the homes ductwork. 

The second type of system is a ductless split system.  This system has a condenser that is directly connected to an indoor unit that directly distributes the air into the space without the use of ductwork.
