Frequently Asked Questions

HVAC Questions

Should I replace my ductwork?
Older homes may require updated duct systems. Like everything, duct systems have evolved and improved over time. Each home has its own individual characteristics and requirements. If you have any questions or concerns, call John Waters for a review of your system.
Do I need a permit to install a new HVAC system on my property?

John Waters Heating and Cooling recommends that anytime a heating or air conditioning unit is replaced, a permit and inspection be obtained. We recommend this because it provides you the homeowner, or property owner, third party verification that the system was installed correctly and is safe to operate. Local jurisdiction dictates permitting and inspection requirements. These requirements may vary based on the jurisdiction being state, county, or city. You should be able to determine the requirements for your area by contacting your local building authority.

What is the average lifecycle of an HVAC system?

With proper maintenance, a good-quality air conditioning unit should last 12-15 years, and gas furnaces can last up to 15-20 years. A heat pump unit, which heats and cools, should provide 10-14 years of service.

What’s the best way to avoid costly repairs to my heating and air systems?

Like any other mechanical piece of equipment, heating and air conditioning systems require maintenance and occasional parts replacements. Think of it like your car – regular oil changes, occasional brake replacements, and a tune up will keep you safe and on the road. Unlike your car, you and your house depend on your heating and cooling system 24/7 – so keeping it well maintained and repaired when needed will improve the life expectancy and efficiency of your HVAC equipment. Regular HVAC inspections, service, and maintenance by a trained certified technician are by far the best way to avoid expensive breakdowns and repairs. Regular filter changes can keep your equipment performing at its peak. We offer several affordable plans for regular maintenance, service, and safety checks for the spring and fall.

Do I need a warranty or extended warranty on my HVAC system?

When purchasing an HVAC system from a reputable manufacturer and dealer, the equipment comes with a warranty at the time of purchase. Extended warranties are available to provide additional coverage. Be sure to understand what you are buying and what it covers. For example, a compressor warranty may not include coverage for labor, refrigerant, etc. We strongly recommend checking manufacturer’s websites and reviews.

How can I prevent carbon monoxide poisoning?
  • Properly place carbon monoxide alarms on every level of your home and in every sleeping area.
  • Schedule regular inspections and cleanings of your heating system and vents.
  • Never use a gas range or oven to heat the home.
What’s the best way to keep my HVAC system running efficiently?
  • Change your air filters regularly (every three months is a good rule of thumb)
  • Upgrade your thermostat. Programmable thermostats can help reduce heating and cooling bills.
  • Pay attention to your vents. Close off vents to rooms you don’t use often. Keep toys, clothes, and furniture away from vents and air returns to avoid blockages. Clean return vents frequently to keep dust and debris from clogging your system.
  • Schedule regular maintenance. The best way to keep your HVAC system running smoothly is to keep it well maintained and professionally serviced.
  • Use your yard! Take advantage of shade trees to keep the house cool. Also remember to keep grass clippings and other debris away from the external unit to avoid clogging the airways.
