If you are thinking of replacing your old AC units with new models or moving to a new property and need HVAC, you are probably aware of how significant this investment will be in terms of comfort. You can enhance the air quality on hot and humid days so that all the household members can enjoy the summer without feeling hot and bothered. One of the most expensive investments you are likely to make is getting an air conditioner for your new home. It is important to choose the right system.

There are different types of ACs including, portable, window, in-the-wall single units, and central air conditioners. The central AC units circulate air throughout the house and work efficiently to keep the entire home cool in the summer months and warm in the winter months. Due to the high cost of energy that most homeowners face today, choosing a central air conditioning system is a better option.

To reduce wastage on energy, every AC unit is given an efficiency rating, called Seasonal Efficiency Rating. It is important that you pay attention to this rating before buying a HVAC unit. Generally, the higher the number, the more efficient the system will be for cooling. Remember that the rating should be at least 13, but some newer models even have ratings of up to 17.

To get the highest ratings, ACs must have large-sized coils for extra efficiency in transferring heat. They must also come with a variable speed blower that minimizes power consumption and is tailored to the need of the consumer. Look for a fan-only switch, which allows you to switch off the cooling without the fan being turned off. This is a more affordable and natural way to cool the house in milder weather.

The modern AC units should also have an automatic delay fan setting that keeps the fan working long enough after the compressor has stopped. There should also be an indicator light that lets you know when the filter needs replacing. This will boost efficiency by ensuring that the unit is properly maintained. As a rule of thumb, AC filters require changing once every three months or so.

The warranties that AC units come with should last for at least 5 years. Before buying these systems, make sure you read the terms and conditions and understand the servicing or repair restrictions. The warranties offered by manufacturers can differ from one another, but all in all, they should cover most of the unit and its various components.

Some manufacturers also offer limited lifetime warranty. This is something you should look for when purchasing a new unit. It covers the compressor or heat pump for as long as you are the owner of your home.

In conclusion, always read the warranties carefully and understand what they cover and do not cover. If any time during the warranty period you authorize an inexperienced person to service the AC unit, the warranty will be void. It is, therefore, advisable to use the same service engineers who installed the units in your home. Remember that most warranties do not cover cleaning and damage that is cause by negligence.
