If you’re dealing with an HVAC issue, you probably have a lot of questions. Here are our answers to a few that we hear most often. If you have a question that’s not answered here, just contact us.
Doesn’t each room need 100 CFM of airflow for comfort?
Maybe… Is 100 CFM what the load calculations show is needed? There is no such thing as a minimum airflow threshold for each room. The amount of air required is in direct proportion to that room’s heating and cooling load. If the calculations show a small load and only 40 CFM required, then you should supply 40 CFM. In fact, oversupplying 100 CFM will actually cause discomfort, since that room will always be a few degrees off from the rest of the space. Sitting under an oversupplied register could be loud and drafty as well.
How expensive are air conditioning and heat pump systems?
Many factors affect the cost of a heating or air conditioning system, including the size of your home, the type and condition of the ductwork installed and accessories you might need such as a thermostat or an electronic air cleaner. We have a complete range of systems and accessories available to meet all your needs, including your financial ones! Your Spicer Mechanical home comfort specialist will be happy to assist you in finding the right system to meet not only your comfort needs but also your household budget.
How long can I expect a new system to last?
If you have a qualified technician perform the regular preventative maintenance and service suggested for your unit, industry averages suggest that an air conditioner should last 12-15 years (sea coast applications may be less). A gas furnace should last as many as 20-25 years.
Should I be concerned about Indoor Air Quality?
According to the Environmental Protection Agency (EPA), your exposure to air pollutants can be up to 100 times higher indoors than outdoors. Air scrubbers and active filtration are ways we can help rid your home of allergens and toxins to improve your health.
Should I repair or just replace my old heating and cooling unit?
If the cost of energy and maintenance seems too high, it likely is. A new heating and cooling unit will be worry-free, and you won’t have to consider whether the latest Band-Aid repair will get you through the next season.
Just switching to a modern air conditioning unit with a SEER rating of 16 can save $50/year from the older models that typically have a rating of about 13 or less. If you schedule an appointment, we can give you an assessment of just how old your unit is and how much energy savings you can gain by getting a modern, high-efficiency unit.
What does the air handler do for my system?
An air handler circulates conditioned air produced by heating and cooling equipment throughout your home. With the air handler, it is easy to filter, humidify or dehumidify the air stream as needed.
What is involved in installing a new system?
If a system is being added to the home for the first time, most of the items noted in the previous question and answer may be required to install the new system. Besides the equipment, the most significant component is ductwork. The ductwork can be made of either metal or fiberglass. The ductwork needs to be properly sized to deliver the right amount of air to each room. A central air conditioning system uses supply and return ducts. The supply duct is attached to the outlet of the furnace or air handler and delivers air to individual zones in your home.
When should I replace my AC unit?
This is a great question! When your energy bills are starting to irritate you or when you feel that you’re starting to get hot and cold spots within your home. Contact us today and we’ll help you make the best decision possible.
Will small systems have enough power to get the air to all the rooms?
Smaller systems do not mean less power.
The smallest split systems available are 1.5 tons, which is really not that small. Second of all, 1.5 ton air handlers are rated to 0.5 IWC external static pressure just like 2 and 2.5-ton systems. If that sounds like gibberish, it means 1.5 ton systems have the exact same “power” to push air through long runs as larger systems.
The blower motor is smaller only because it’s pushing less air, just like a motorcycle has a smaller engine than a car but can still accelerate as quickly. We have seen 1.5 ton systems used in 1500+square feet 2-story homes. If you can’t get air to a 900 square foot apartment, you have a duct sizing issue, which would be a problem no matter what size the air handler.
