Central Air Conditioner Troubleshooting


In order to get the most out of your central air conditioner, it is important to do routine maintenance. Keeping your unit clean and operating properly will not only extend the length of its life, but it will also run more cost effectively. There are many potential issues or problems your system may face as it ages, but not all of them require a certified technician to address them. Fortunately, there are many things you can do on your own to ensure your air conditioner is running at its best and keeping your home comfortable. Here are central air conditioner troubleshooting ideas to help you learn what you can do if you ever face common, easy-to-fix problems. Continue reading

April Brings Sunshine & Preseason Specials

Put away the snow blower and get out the gardening tools! April is here and it’s great to see kids outside playing and folks out exercising (some run- I walk…fast). This rough winter will make the bloom of spring that much sweeter!

As warmer weather sets in be sure to get your cooling system ready for summer. A preseason air conditioning check will ensure that your system is ready for the humid days ahead. Your air conditioner transfers indoor heat to the outside by removing warm air from your home as it’s drawn across the coils in your AC unit, resulting in the cool, comfortable temperature you’ve come to expect. For this transfer to be efficient, the coils in your outdoor unit need to be professionally cleaned. Don’t wait until the hot weather is here to call for your air conditioning check. Call now and take advantage of our preseason special! Continue reading

Improving Performance

Poor installation, duct losses, and inadequate maintenance are more of a problem for air conditioners than for combustion furnaces. A growing body of evidence suggests that most heat pumps have significant installation or service problems that reduce performance and efficiency.According to a report on research funded by Energy Star more than 50 percent of all air conditioners have significant problems with low airflow, leaky ducts, and incorrect refrigerant charge.

Repairing an Air Conditioner

What an individual should know

Before hiring a repair service for air conditioners, people should know certain aspects of AC systems. When Ac systems develop some kind of fault, individuals often try to mend it by themselves without knowing all the concepts involved. The usual office or home air conditioner operates by easy physics, and it consists of 2 separate parts – the evaporator and condenser. These units are sealed and people cannot mend any of the faults in these parts by themselves; they will have to call some trained professionals. However, one can try to keep everything neat and clean so that debris does not accumulate. Continue reading

Maintaining and Servicing

A/C performance will deteriorate without regular maintenance and service. The difference between the energy consumption of a well-maintained air conditioner and a severely neglected one ranges from 10 to 25 percent.

Regular Maintenance

  • Clean or replace filters regularly (every 2 to 6 months, depending on operating time and amount of dust in the environment).
  • Clean outdoor coils as often as necessary (when dirt is visible on the outside of the coil).
  • Remove plant life and debris from around the outdoor unit.
  • Clean evaporator coil and condensate pan every 2 to 4 years.
  • Clean the blower’s fan blades.
  • Clean supply and return registers and straighten their fins. Continue reading

Operating an Air Conditioner

Like combustion systems, you control air conditioners using thermostats. If you leave and return at regular times everyday, you’ll save money by using automatic thermostats, which minimize energy use during the times the home is unoccupied. However, choosing an automatic thermostat’s reactivation time requires considering the duration of A/C operation necessary to restore a comfortable temperature. During the heating season, some homeowners also set their thermostats back 10°F, manually or automatically, when they leave home or go to bed.

A two-stage thermostat controls the heating. The first stage activates the refrigeration system. If it’s too cold outside for the refrigeration system to counteract the home’s heat loss, then the thermostat’s second stage activates the electric resistance coils. An outdoor thermostat will prevent the less efficient electric resistance heat from coming on until the outdoor temperature falls below 40°F. An outdoor thermostat also will prevent auxiliary hea t from activating when an automatic thermostat is warming the house after a set-back period. Use setback thermostats that are only for heat pumps. Continue reading

Installing a New Air Conditioner

An air conditioner’s performance and energy efficiency not only depends on the selection and planning of the equipment but also on careful installation.

Consumers and home builders alike tend to accept the lowest bid for heating and air-conditioning work. This unfortunate choice can often leave a system lacking 10 to 30 percent in the materials and labor necessary to optimize air conditioner performance. Rather than just accepting the lowest bid, it’s best to research the performance records of local contractors, and get involved in the planning and decision-making about your new A/C system.

Selecting an Air Conditioner

When selecting an air conditioner, consider the following three characteristics carefully: the energy efficiency rating, sizing, and the system’s components.

Energy efficiency rating

In the United States, we rate an A/C’s energy efficiency by how many British thermal units (Btu) of heat it moves for each watt-hour of electrical energy it consumes. Every residential air conditioner sold in this country has an EnergyGuide Label, which features the A/C’s heating and cooling efficiency performance rating, comparing it to other available makes and models.

The Heating Seasonal Performance Factor (HSPF) rates both the efficiency of the compressor and the electric-resistance elements. The HSPF gives the number of Btu harvested per watt-hour used. The most efficient A/Cs have an HSPF of between 8 and 10. Continue reading
