FAQ

My air conditioner is running all day, but why is my house not cool?

Please check the following things:

  • Is your furnace filter dirty? Please change it if it is clogged with dirt and dust.
  • Check all return air grilles to make sure they are not blocked by furniture.
  • Check all supply air registers to make sure they are open and blowing air. (The return air grilles are normally located on your walls and are wide and flat).
  • Check the SSU switch (it looks like a light switch on a gray box located at the furnace) to be sure it is in the “ON” position.

All above check ups can be done by yourself. THere are other possible reasons that will require a service call:

  • Check your outdoor unit – it may be dirty and require cleaning by service technician.
  • The compressor could be damaged.
  • The refrigerant charge could need attention

When should I replace my air conditioner?

The average central air conditioner lasts 15 years while the average room air conditioner lasts 10 years. Once you pass the life expectancy of an air conditioner you may want to begin gathering information on which bands of equipment and which dealer you want to replace the air conditioner.

When replacing an air conditioner, make sure it is installed in a shady spot. This can save one to two percent of the energy bill. Avoid placing the air conditioner on the roof or in the attic whenever possible.

How can I avoid and deal with Ice Damming?

To avoid Ice Damming, you need to stop the warm air that is leaking from the interior of your house and keep the attic temperature cooler. You also need to adequately ventilate your attic. Direct Energy can provide the roofing or insulation expertise with a no-obligation, in-home estimate. Have ice removed by a professional – do not attempt to do it yourself.

Why is there water on the floor by the furnace?

Your condensate drain for the air conditioner may be clogged with debris. Please make a service call to clear it.

Ice covering the outside of the cooling coil on my furnace. What should I do?

Before our technician can work on the equipment, you need to get rid of the ice. Here is what you need to do:

  • Turn the air conditioning switch on the thermostat to OFF. This will prevent your heating and cooling equipment from turning on.
  • Raise the temperature on the thermostat to the maximum temperature. This will prevent the outside (condenser) unit from coming on.
  • Turn the Fan switch to ON (it is probably in the AUTO position right now).
  • Leave the furnace fan running until a technician arrives. This will allow the ice to melt and the technician will be able to diagnose the air conditioner system upon arrival.
  • After clearing the ice, feel free to place a service call.

My air conditioner does not appear to be cooling. What should I do?

Please check the following items:

1. Power switch is ON Generally there are two switches: one for the furnace and one outside by the air conditioner unit.

2. Thermostat set to the cooling position.

3. Electrical breaker is ON.

4. Fuses is in working condition .

5. The furnace filter is clean. A furnace filter that is clogged with dust and dirt can result in your air conditioner not working.

6. Check the outside temperature. If the temperature is below 13 degrees Celsius or 55F, your A/C may have a safety measure that prevents the unit from running when temperatures are below 13C/55F.

If you have done all above chckups and your air conditioner is still not cooling, you need to call for service.

Why do only some people seem to develop symptoms?

As with any other occupational illness, not all people are affected with the same symptoms or to the same extent. Some people may be more sensitive than others. Some people may be exposed to more contaminants in the building than others and they may experience symptoms earlier than other people. As air quality deteriorates and/or the length of exposure increases, more people tend to be affected and the symptoms tend to be more serious.

What symptoms are often linked to poor indoor air quality?

It is common for people to report one or more of the following symptoms:

  • dryness and irritation of the eyes, nose, throat, and skin,
  • headache,
  • fatigue,
  • shortness of breath,
  • hypersensitivity and allergies,
  • sinus congestion,
  • coughing and sneezing,
  • dizziness, and/or
  • nausea.

People generally notice their symptoms after several hours at work and feel better after they have left the building or when they have been away from the building for a weekend or a vacation.

Many of these symptoms may also be caused by other health conditions including common colds or the flu, and are not necessarily due to poor IAQ. This fact can make identifying and resolving IAQ problems more difficult.

What are indoor air contaminants?

Here are examples of common indoor air contaminants and their main sources:

  • Carbon dioxide (CO2), tobacco smoke, perfume, body odours — from building occupants.
  • Dust, fibreglass, asbestos, gases, including formaldehyde — from building materials.
  • Toxic vapours, volatile organic compounds (VOCs) — from workplace cleansers, solvents, pesticides, disinfectants, glues.
  • Gases, vapours, odours — off-gas emissions from furniture, carpets, and paints.
  • Dust mites — from carpets, fabric, foam chair cushions.
  • Microbial contaminants, fungi, moulds, bacteria, — from damp areas, stagnant water and condensate pans.
  • Ozone — from photocopiers, electric motors, electrostatic air cleaners.

What are the common causes of IAQ problems?

IAQ problems result from interactions between building materials and furnishing, activities within the building, climate, and building occupants. IAQ problems may arise from one or more of the following causes:

  • Indoor environment – inadequate temperature, humidity, lighting, excessive noise
  • Indoor air contaminants – chemicals, dusts, moulds or fungi, bacteria, gases, vapours, odours
  • Insufficient outdoor air intake

What is Indoor Air Quality?

Indoor Air Quality (IAQ) refers to the effect, good or bad, of the contents of the air inside a structure, on its occupants. Usually, temperature (too hot or too cold), humidity (too dry or too damp), and air velocity (draftiness or motionlessness) are considered “comfort” rather than indoor air quality issues. Unless they are extreme, they may make someone unhappy, but they won’t make a person ill. Nevertheless, most IAQ professionals will take these factors into account in investigating air quality situations.

Good IAQ is the quality of air which has no unwanted gases or particles in it at concentrations which will adversely affect someone. Poor IAQ occurs when gases or particles are present at an excessive concentration so as to affect the satisfaction or health of occupants.

In the minor instances, poor IAQ may only be annoying to one person. At the extreme, it could be fatal to all of the occupants of a structure.

It is important to note that the concentration of the contaminant or contaminants is crucial. Potentially infectious, toxic, allergenic, or irritating substances are always present in the air. There is nearly always a threshold level below which no effect occurs.

When should I replace my furnace?

The average 80% standard oil or gas furnace lasts 18 years. Most high efficiency 90%+ furnaces only last 12 years due to their longer run times and design characteristics. It makes sense to have your furnace checked by an HVAC professional every few years. This is especially true for older units. Once you get past the life expectancy of the unit consider planning for a replacement unit.

We highly recommend you plan for furnace replacement before your old furnace breaks down. This way you take time to shop for the best deal, and install it on your own schedule If you wait till its breaks down (probably on the coldest day in the winter) you are usually in an emergency situation and might be ripped off.

These symptoms can indicate a furnace should be replaced

  • Frequent pilot light outages
  • Delayed ignition
  • Yellow flame or wavering flame
  • Excessive soot or corrosion
  • Too much or too little heat
  • The smell of sulfur or burnt eggs

What is the purpose of a furnace filter?

Furnace manufacturers put inexpensive fiberglass filters into their furnaces to remove airborne particles that might damage the fan and the heating coil. Particle buildup can also decrease the efficiency of your furnace, as the furnace has to work harder to pull air through the intake. More expensive filters can also improve the air quality in your house by removing pollen, bacteria and mold spores from the air. This is especially important if you or someone in your family suffers from allergies.

How do I determine which filter to buy for my particular model of furnace?

There are several sources of information you can check: the documentation that came with your furnace; the HVAC contractor that installed or services your furnace; your furnace manufacturer; or a furnace filter vendor.

How often do I need to change my furnace filter?

Check the documentation that came with your furnace. Recommendations vary based on a number of factors: the type of filter that you use, how many pets you have, whether anyone in your home has allergies, etc. If you use disposable fiberglass panel or electrostatic panel filters, you should change them anywhere from once a month to once every three months. Pleated filters generally last from 3 months to a year.

How can I reduce my hot water heating costs?

It’s easier than you may think – and you don’t have to sacrifice comfort or convenience. No-cost measures include taking a short shower instead of a bath, washing and rinsing clothes in cold water and using the dishwasher only when it’s fully loaded.

Investing a few dollars will generate even more savings. For example, installing low-flow shower heads can reduce hot water consumption by 30 percent. Similarly, water-saving aerators can be installed on kitchen and bathroom faucets. New washers can fix leaky taps, and hot water pipes can be insulated at a small cost. You can also consider insulating the water heater itself (check with the supplier first)

If you’re in the market for a new water heater, make sure it’s energy efficient, since this could be your best opportunity for long-term cost savings.

When should I change my water heater?

The life span of a water heater can range from four to 13 years (depending on the mineral content of your water, the water quality, usage and other factors). A typical model, however, lasts about seven years. If your water heater is at least seven years old, you may want to start thinking about replacement options so that you’re not forced into a hasty decision when it does quit – usually without warning!

Why does it take so long to get hot water to my faucets?

The time it takes to get hot water from the water heater to the faucet depends on the distance the hot water must travel in the pipes. If you have a faucet that is more than 20 feet from the water heater, you may need to run water more than 20 seconds before it comes out hot.

Water Heaters Come in a Variety of Sizes?

Both residential gas and electric water heaters come in a variety of sizes but the most common are:

  • 40 gallon
  • 50 gallon
  • 60 gallon
  • 75 gallon
  • 80 gallon
  • 120 gallon

Can I downsize of my water heater from 60 gallons to 40 gallons?

Sure. If your current water heater is now too large due to changes in your family size or lifestyle changes, we can replace your 60 gallon water heater with a 40 gallon water heater.

Can I upgrade the size of my water heater from 40 gallons to 60 gallons?

Yes. If you are experiencing insufficient hot water due to changes in family size or lifestyle changes, we can replace your 40 gallon water heater with a 60 gallon water heater.

What size of water heater do I need?

This depends on how much hot water your household uses at peak hours – which is affected by the number of people living in your home and their water-using habits – and how different models can meet that need. Keep in mind that lack of space may prevent you from installing a large unit even if you want one. And bigger is not necessarily better: installing a unit that’s larger than you need will waste energy and money, since you’ll be heating too much water.
