Frequently Asked Questions

Heating and Cooling

Q. What regular maintenance do heating and air conditioning systems need?
The most important part of maintaining your system is making sure that air is flowing properly. That requires a regular check of all filters to make sure they are clean and changing them on a regular basis.

Beyond that, we recommend that you have your system checked twice a year in spring and fall. These checks will ensure a long, quiet life for your heating and cooling system. This is an automatic benefit of membership in the Patterson Comfort Club! Contact us to learn more.

Q. How often should I replace my filters?
In general, 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. If filters look dirty, they need to be cleaned or replaced.

Q. In addition to changing my filters, what maintenance should I do on my heater and/or air conditioner?
In general, we don’t recommend that you start pulling covers. It’s best to call a trained technician to handle the workings of your system. But here are some things that you can do help your system perform at its best:
Clear any outdoor units of debris and weeds to ensure proper airflow. Always use caution when using mechanical weed trimmers, taking care to avoid wiring. And make sure pets don’t use outdoor equipment as their bathroom; their urine can cause expensive damage.

Q. Should I schedule regular maintenance on my air conditioner?
It’s a good idea to have a preventive checkup at least once a year in the spring or early summer (before the temperatures peak). It’s the best time to spot any potential problems before they cause a service interruption.

Q. What should I check before I call for service?
Check to be sure that the air conditioner or furnace is turned on. Check that the breakers and any disconnect switches are turned on and be sure the thermostat is set correctly. Also make a note of any strange noises or smells.

Q. How do I know if my system is working properly?
Is your system heating and cooling your home as it should? Is it making strange noises? Are you noticing changes in the cycling pattern or think it is taking longer to work? Are your utility bills rising without any other explanation? These are all signs that you may have a problem that needs service. In most cases, the longer you delay, the worse any underlying problems will get.

Indoor Air Quality

Q. What types of equipment are available to improve indoor air quality?
Electronic- or Media-Type Air Filters: These types of systems will help eliminate smoke, pollen, odor, dust mites and allergens. This will allow you to breathe easier, sleep better and enjoy your home more.

Whole-House Humidifiers: Whole-house humidifiers maintain consistent humidity levels throughout your home. Maintaining a humidity level of 35-40% during the heating system (season) will make your home more comfortable at a lower temperature and help preserve some home furnishings.
Ventilators: Air-to-air heat recovery ventilator systems remove contaminated air from inside the home, while bringing in fresh air from the outside that is warmed during the transfer process.

Air Purifiers: Ultra-violet light emitting appliances like the APCO UV germicidal light are an effective way to dramatically reduce organic contaminants.  See www.freshaireuv.com for more info.

Q. How important is air quality and what factors need to be considered?
Indoor air quality is a matter of both comfort and health. There are systems that are built into many heating and cooling systems and others that can be added to an existing system. The key is determining the source of any problem and prescribing the best type of system to yield a long-term improvement.

Q. Do electronic air cleaners really work?
We only carry products that have been proven to be effective. Matching the system to your problem is the key. If you suffer from allergies, it’s good to know that the more efficient systems can remove dust and pollen particles as small as .1 micron.
