Air Conditioner Tips

What do good air conditioning units have in common?

The best ones are efficient, operating on minimal electricity to reduce the cost of utility bills. Energy efficient air conditioners provide steady, dependable performance year after year when properly maintained. Good air conditioning systems are quiet, long-lasting, and low in service needs.

How can I be sure my air conditioning unit is the right size?

An air conditioner that’s too small won’t keep your home sufficiently cool. However, an over-sized system will cycle (turn on and off) more than necessary, wasting energy and putting undue strain on the compressor. DG Heating & Cooling will help assess what size Ruud air conditioner is best suited for your home. Factors such as window dimensions and exposure, floor space, insulation, local climate, heat-generating appliances, the direction your home faces, and even the amount of shade produced by trees on the property all come into play when determining what air conditioner will work most efficiently for your home cooling needs.

Which air conditioners are energy efficient?

Air conditioner manufacturers are required, by law, to evaluate and rate their equipment according to its "energy efficiency". This rating is known in the HVAC industry as SEER (Seasonal Energy Efficiency Rating). The higher the SEER, the more efficient the air conditioner.

Property owners can upgrade their air conditioning with a more energy-efficient system. High SEER models may incur a higher initial investment, but easily make up the difference by reducing home energy bills over the long run. Ruud air conditioners are ahead of the curve when it comes to energy efficiency and SEER ratings.

Air Conditioner Service Tips

Clean Indoor & Outdoor Coils of an Air Conditioner

Dirty coils reduce the operational efficiency of your air conditioning system, costing more in energy bills and increase wear-and-tear.

Maintain Refrigerant Levels

Too much or too little refrigerant can damage an air conditioner's compressor leading to decreased efficiency.

Ensure Maximum Air Circulation

Clean and adjust an air conditioner's blower components to provide proper system air flow for higher comfort levels.
