How should I maintain my HVAC system?

Routine maintenance by a trained professional is vital to keep your HVAC system operating efficiently.

Filters should be chacked each month and changed regularly (this will vary from home to home). Keeping your filters clean will ensure maximum airflow and air quality.

All HVAC systems should be inspected twice a year by a trained professional. A clean and well maintained HVAC system will perform better and last longer.

Why is my HVAC system freezing up?

There are several things that can cause your HVAC system to freeze up; most of them usually need to be corrected by a professional technician. Making sure the filter is clean or replaced and making sure the airflow is not restricted are about the only things you can check or handle yourself.

Low refrigerant: In some cases, freezing up is caused by a leak in the refrigerant lines. Weak solder joints, friction from piping rubbing or vibrating against an object, leaking valves or loose fittings can cause leaks. The age of the system and the nature and location of the leak are the determining factors on whether to have the system repaired or replaced

Dirty evaporator coil: Over time, the evaporator coil will become dirty. When this happens, the results are similar to those of having a dirty filter. Gradually you will lose airflow, slowly enough that you probably would not realize it until it freezes up or is not cooling adequately.

Defective blower motor or relay: A blower motor not running at the proper speed or not running at all can cause freezing. It can also be intermittent, starting at full speed and slowing down after it heats up. Or a relay could cause it to start one time and not the next.

 Should you find that your system was freezing due to a dirty filter, after replacing or cleaning the filter, you can speed up the thawing process by turning the system off and turning on the fan. If you have a heat pump system, you can try turning the system to heating mode until the ice has melted. After the ice has melted, switch the system settings back to normal. If the system refreezes, contact us to correct the problem.

How does a central A/C system work with a furnace?

The system is connected to the inside cooling coil, which to deliver the highest system efficiency, performance and climate control, must be matched in size and rating with your air conditioner. The compressor pumps refrigerant back and forth, extracting heat and moisture from the indoors and transferring the heat outdoors. Warm indoor air is blown over the inside coil, cooled and distributed throughout your home. Furnaces are designed to provide maximum heat with minimum fuel usage.

How does a Heat Pump Work?

Unlike a furnace, a heat pump does not burn fuel to make heat. It simply uses electricity to move heat from one place to another. A heat pump is an energy-efficient way to cool your home in the summer and heat it in the winter. This means it operates at low speed most of the time. However, on days when more heating or air conditioning is required, it switches to the next stage for maximum comfort.
