We want to help you to choose the right furnace or central air conditioner for you—and to get the most out of it for years to come.

Frequently Asked Heating & Cooling Questions

How can I troubleshoot my own system?

Nobody wants to pay for unnecessary service calls. If your heating or cooling system isn’t working, or isn’t performing as it should, start by performing a few simple checks yourself – you might just save time and money.

  • Are all on/off switches in the correct position? Check indoors for heating systems, outdoors for air conditioners.
  • Are any fuses or circuit breakers blown?
  • Are your thermostat settings correct? For cooling, ensure that your system switch is in the COOL position; for heating, make sure it is set to HEAT or Auto.

Why is preventative maintenance important?

Your furnace, air conditioner, and heat pump are precision-engineered, heavy duty systems which undergo long periods of intensive operation. No matter how well built, they can be expected to wear over time – and the lack of regular maintenance can accelerate that process. By changing filters, performing cleanings, and conducting other recommended regular maintenance as required, you extend the life of your systems and increase their efficiency.

What routine maintenance should I perform?

Every furnace and air conditioner is different, and manufacturer’s specifications vary. However, you should expect to regularly inspect and replace your furnace’s air filter, clean dust and dirt from your air conditioner’s outside unit according to the manufacturer’s instructions, and get your systems professionally inspected at least once a year to ensure optimal performance.

How often should I change my air filter?

You should inspect your air filter monthly, and replace it at least every six months. If you have a reusable air filter, clean it according to this schedule, or more often if it is especially dirty.

How often should I change my humidifier filter?

You should replace your humidifier filter at least once a year. Excess build-up of minerals, dirt, and pollutants can cause wear and damage to your humidifier, as well as making it operate less efficiently.

When should I turn my humidifier off and on?

Turn your humidifier on in the fall and turn it off in the spring.

How often should I change my thermostat batteries?

Change your thermostat batteries at least once per year, or more often if you notice any problems with inconsistent operation. Note that low batteries can cause your furnace or air conditioner to operate inconsistently, or not at all.

How do I clean my exterior air conditioning unit?

Clean your air conditioner’s outdoor unit as needed, but it is a good rule of thumb to clean it both at the beginning and the end of the operating season. With the unit switched off, use a garden hose to clean the exterior surface. For extremely dirty units or if dirt has collected in the air conditioner coils, contact Ehlers to schedule maintenance.

Why should I have my heating and cooling systems inspected? They seem to be working fine.

Regular inspection is a condition of most manufacturers’ warranties. Your system should be cleaned, inspected, and maintained according to the manufacturer’s recommendations. If not, needed repairs may not be covered.

Your furnace, air conditioner, and heat pump are some of the most expensive—and the most important—parts of your home. Taking care to address small problems early can prevent bigger, more costly problems later on. Your trained Ehlers technician will inspect your system thoroughly, check for any worn, damaged, or incorrectly operating components, and will make sure that your system is operating at its peak efficiency. This will save on your energy costs, as well as saving wear on the system.

How often should I have my system inspected?

You should have your heating and cooling systems professionally inspected at least once per year, preferably just before the beginning of the operating season: Fall for furnaces, spring for air conditioners.

What would void my manufacturer’s warranty?

There are a number of circumstances that can void a manufacturer’s warranty:

  • Failure to perform inspections, maintenance, and cleaning as required
  • Use of counterfeit, non-standard, or non-authorized parts or accessories
  • Installation of any system or component by anyone other than a licensed, certified contractor
  • Relocation of heating/cooling equipment from its original position in your home

Your manufacturer’s warranty provides important protection for you in the event of a breakdown. If you are unsure about any aspect of repair, maintenance, inspection, or installation of your system, contact Ehlers for a consultation.

How can I increase the efficiency and life of my home’s heating and cooling systems?

Apart from routine maintenance, there are a few ways to increase your system’s operation:

  • Clean and replace your filters frequently.
  • Turn on the blower, which provides constant air movement throughout the home, and allows for better filtration.
  • Install shades, drapes, shutters, or screens on windows that are exposed to extreme sunlight to keep room temperatures at moderate levels.
