HVAC FAQs (pg. 2)
Is a system with more capacity better?
No. A larger system with more capacity delivers less comfort and costs more to operate. An air conditioner is at its least efficient when first turning on. A system with too much capacity will run in numerous short cycles, turning on and off repeatedly, therefore causing it to be less efficient. Also keep in mind that an air conditioner only removes humidity when it's running, so a system with shorter run cycles doesn't remove humidity from the air very well.
How long should my system run in a cycle?
There is no exact answer for how long your system should run during each cycle. The average air conditioner is sized to remove the heat from your home as fast as it comes in, on a 95° day. Therefore, ideally, on a 95° day the system should be able to keep up with the incoming heat, but not gain on it and be able to turn off. The cooler it is below 95°, the more the system will cycle on and off.
What air temperature should my air conditioner produce?
The air temperature your system produces depends on the temperature of the air going into the system. Generally, the air produced should be 18°-20° below what enters the system. So if the air entering the system is 80°, the air exiting should be about 60°-62°. However, that only works on a system that has been running at least 15 minutes on a warm, dry day with a home that is about 80° inside. On a mild day, with an indoor temperature in the low 70's, or during humid conditions, the air coming out may only be 15°-17° cooler than what enters.
What temperature should I set my thermostat?
Obviously the time of year becomes a big factor for desired temperature settings. In the summer months the average temperature setting is 78°-80°, in the winter 70°-72° seems to be the most common setting.
What are the advantages of a programmable thermostat?
Different programmable thermostats offer many different features. However, because they are electronic, they are all more accurate and efficient than thermostats that contain mercury. With programmable thermostats you can control the temperature in your home at different times of day without ever touching your thermostat. Because everything is automatic, you will never forget to change the setting on your own.
How often should I replace my filters?
For optimum efficiency and filtration, we recommend that you replace your disposable filters at least once a month. If you have washable filters, they should be cleaned once a month. Some high capacity whole house air cleaners can last up to 1 year and should be replaced according to manufacturers instructions.
What maintenance should I do on my air conditioner?
The most important maintenance you can do is to change your filters regularly. Ground mounted outdoor units need to be kept clear of debris, clutter; weeds or landscaping that can grow too close and reduce the airflow to the unit. Also, keep pets away from the unit because pet urine can cause expensive damage. Use caution with a weed trimmer around the unit to prevent damaging control wiring. Any additional maintenance should only be performed by qualified personnel.
How often should I have maintenance done on my air conditioner?
You should have maintenance done on your air conditioning system once a year. This not only ensures maximum efficiency, it enables us to foresee any possible problems that may occur in the near future. Our Preferred Service Plan is specifically designed to keep your air conditioning system running at its peak efficiency year-round.
Is there anything I should check prior to calling for service?
Yes. Check to be sure that the air handler or furnace is turned on. Check that the breakers and the disconnects are turned on and be sure the thermostat is set correctly.
How much does a new replacement system cost?
Due to the many different makes, models and customer needs, price is an issue that can only be solved by doing a thorough evaluation of your home and existing equipment. There is no charge for an in-house replacement proposal.
Are there any air conditioning systems that are safe for the environment?
Yes. All manufactures have developed new systems that contain the environmentally friendly R410A, or Puron, refrigerant. Visit our products page to view our entire line of Puron products.
