Heating and cooling systems are sized according to their tonnage. One (1) ton equals 12,000 BTU/H. Residential systems can range from 1 to 5 tons.
As a rule of thumb, the maximum AC unit size you need to install should not be more than 15% more than the BTUs you need to cool your house. This means that if your house requires a 24,000 BTU unit (2 tons), you should not install one that is larger than 30,000 BTUs (3 tons) to maintain energy efficiency.
The SEER is a measure of the cooling power of an air conditioning system per unit of power consumed. It is calculated by dividing the cooling power provided by an AC per hour by the number of watts of electricity consumed.
Keep your vents clear. Don't let furniture, boxes, or toys block them. Make sure you change your AC air filter as often as you're supposed to — once a month for most air filters. Make sure the condenser unit is free of debris (that's the big unit outside).
In short No. Oversized equipment can lead to more frequent breakdowns, earlier need for replacement, lack of temperature consistency, increased energy bills, poor air quality, and excessive noise.
Ideally, a properly operating air conditioner should cycle for roughly 15 to 20 minutes, two to three times per hour. If the temperature inside your home is very high, is much higher than the temperature that your thermostat is set at, or the outside temperature is very high, the run time will increase.
An undersized system struggles to cool your home, which is why it's running constantly. This constant running will reduce pressure in the evaporator (cooling) coil until it freezes over. This is dangerous because the freezing can cause liquid refrigerant to flood back to the compressor and damage it.
Well, the general consensus is somewhere between 14 to 20 degrees colder than the intake temperature. From my example, 55 to 61 degrees would be an acceptable range.
According to ENERGYSTAR.gov, the ideal home temperature should be between 70 to 78 degrees Fahrenheit.
A programmable thermostat can save you money by only running when you are home.
You should replace these about every 90 days if you have no allergies, but AC pros typically recommend every 45 days for max efficiency. Be sure to replace them with the right size and type of air filter.
The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters. Clogged, dirty filters block normal airflow and reduce a system's efficiency significantly.
Heating and Air Conditioning equipment, no matter what kind you have, should be inspected, cleaned, and serviced at least once a year. The best scenario is to have the heating system checked in the Fall and the air conditioning checked in the Spring.
We recommend checking the air filter and ensuring the breakers are on.
The average cost to replace an HVAC system is $4,820 to $9,350, which includes the combination of a new central air conditioner unit and a new gas furnace. Installation of a new HVAC system with ductwork costs between $6,820 and $12,350 in total.
Your most eco-friendly air conditioning systems will be ones with a higher SEER rating of 17 or greater.
Electronic air cleaners can be highly effective in removing contaminants from your home’s air, which can help relieve symptoms of allergies, asthma, and other respiratory illnesses.
In short, the answer to this question is no. Although closing off unused rooms may seem like a way to save energy on heating and cooling, it can actually force your HVAC system to work harder.
The hot air from the heater essentially sucks air away from your skin, making you prone to dry skin, nosebleeds, and other health issues. A humidifier adds enough moisture to the air that this is no longer a problem.
The 3 digits in the model number tell you the nominal capacity in thousands of BTU/hr. Since each 12,000 BTU/hr is equivalent to 1 ton of air conditioner capacity, it's easy to figure out how many tons of nominal capacity your AC has.
