Several factors have to be taken into consideration when selecting the right combination of equipment to purchase, such as the initial cost and the energy efficiency rating. The equipment can neither be too small nor too large, but be adequate to cool or heat the area in the home, in which it will required to operate. Any load calculations that have to be determined, can be done by a qualified contractor.
The SEER (Seasonal Energy Efficiency Ratio) ratings, which indicates the efficiency of the air conditioning unit, is an important factor to also consider before purchasing any HVAC equipment. The more recent models have a minimum SEER rating of 13.
In the United States, there are many air conditioning brands that are popular because of their high quality, and these include Bryant, Lennox, Trane, Amana and Carrier. These manufacturers produce models that have excellent cooling and heating features, however the many options to suit every budget, can sometimes leave you confused.
Although price is a huge factor in the selection of a particular brand, it should not be your only consideration, as a less costly system can over the years end up costing you much more. These brands are reliable and of a high quality, and for those that may cost more, you need to be aware that maintenance and servicing will be available to you for a very long time. The systems with high efficiency ratings may cost more up front, but in the long run will definitely save you money.
The upgrade of a unit that has become old, is recommended so as to improve efficiency. Qualification for tax credits is even possible if you upgrade your unit. A regular maintenance schedule is recommended for your air conditioning, to reduce or eliminate any needs for repairs, and for the unit to operate at the optimal level of efficiency.
