Common HVAC Questions

The following are some of the most commonly asked HVAC-related questions.

How Often Should I Change My Filter?
It depends on the type of filter you are using. If you are using a fiberglass filter, you should replace it at least once a month. If you are using a pleated filter, on the other hand, you can go three months without changing your air filter.

How Do I Know If I Should Fix It Or Replace It?
We have all had that one item (a car or television, for example) that we have fixed one too many times before getting rid of it. Any time you have a system that is more than 10 years old, it is probably best to replace it once it starts to falter. The reason for this is because continuously repairing an old system can become quite costly, especially if the system is over 10 years old. Investing in a new system may seem more expensive at first, but will save you money in the long run.

It should be noted that today’s air conditioning systems are about 60% more efficient than those created 10 years ago. An old system takes more power to run, thus using more of your home’s energy resources, resulting in higher electric bills.

How Expensive Are Heating and Cooling Systems?
Many factors go into determining the cost of a new heating and cooling system. The size of your home, the types of accessories needed (number of thermostats, etc.), and your ductwork all contribute to the total cost of a new system, which could run between $1,500 and $5,000.

How Long Will My New System Last?
Provided that you have a qualified technician performing regular maintenance on your system at least once a year, your new system should last between 12 and 15 years.

Why is One Room Always Hotter or Colder Than the Rest of the House?
There is always that one room that is too hot or too cold, even when the rest of the house is the perfect temperature. This can be caused by a number of reasons. Is that room facing the west, facing the sun as it sets? If your room is facing west and/or upstairs, you could be experiencing “stack effect,” or “chimney effect.” The temperature imbalance can also be caused by a duct problem, which needs the attention of a skilled heating and cooling technician.
