How often should I have my boiler serviced?

Boilers should be serviced every year in order to keep them running properly, and as efficiently as possible. Most warranties require regular service in order to keep the warranty valid.

Should I repair or replace my old HVAC system?

There are many factors involved in deciding whether to repair or replace an HVAC system. These include the age of the current system, whether or not there is a warranty left on it, the condition that it is in, and the cost of the repair required. When you have a technician out to your home, they will discuss these details with you, so that you can make an informed decision on how you want to move forward.

How can I save money on my utility bills?

How often should I replace my furnace filter?

Standard 1” filters should be replaced every 2-3 months, however some upgraded filtration options can be good for up to 12 months.

Why is my furnace blowing cold air?

Some furnaces are set up to run the fan 24/7, and the air that blows out of them during the off cycle can feel cool due to the velocity. If your house is maintaining the temperature set point, there is no need for concern, however if it is not keeping up, an HVAC technician should be called to assess.

Can you convert an oil furnace to natural gas?

You can replace an oil furnace with a natural gas furnace, and there are rebates you can be eligible for doing so!

What is the difference between high efficiency and standard efficiency furnaces?

High efficiency furnaces use much more of the heat energy from the gas that they burn. A good way to look at this is percentage of efficiency compared to pennies in a dollar. With a standard efficiency furnace (average 60% efficient) 40 cents out of every dollar is escaping out of the exhaust. A high efficiency furnace on the other hand uses 90-98 cents of every dollar spent converting the heat energy into heat in your home. The exhaust temperature is so low on these furnaces, that they need to be vented with plastic pipe, allowing the exhaust gases that have condensed into water vapour to flow back into the furnace and out of the home through the drain.

What is two-stage heating?

Two stage heating is a furnace with essentially 2 speeds. Rather than running at a full firing rate whenever there is a need for heat, it can operate at a low speed if only a small increase in temperature is required. This means less gas burned, and more money saved. Even better than a 2 stage furnace is a variable capacity furnace which when paired with a variable capacity heat pump can offer up to 56 stages of heating. Talk about savings!

Should outdoor units be covered in winter?

Outdoor units are designed to withstand the elements, however a cover can keep an air conditioner looking brand new for much longer if it is utilized during the winter months. Don’t make the mistake of putting a cover on your heat pump though – as these are designed to run all year long!

What is the benefit of having a heat pump?

A heat pump offers many benefits including a more even temperature throughout the home, a smaller carbon footprint, and increased efficiency (if set up properly).

What is the difference between a heat pump and a furnace?

A furnace burns natural gas to create heat, where a heat pump uses electricity to extract heat energy out of the outside air, and convert it to heat inside your home.

What temperature should I set my thermostat?

It comes down to whether you prefer comfort or efficiency. Most people set their temperature around 70F or 21C – but the decision is ultimately up to you!

How do I know what size air conditioning unit I need for my home?

There are many factors involved in determining what size air conditioner should be installed. This is best left to a professional who will conduct a heat load calculation that considers many factors.

Is a ductless air conditioner more efficient than a central air conditioner?

Like standard air conditioners, Ductless systems come in a variety of different efficiencies or SEER’s. Talk to a comfort advisor to help you decide what is best for you!

Do I need a permit in order to replace my heating and cooling system?

Yes, permit costs carry from municipality to municipality, but permits are required for nearly all heating and cooling system replacements. Gandy Installations can handle the permit process for you from start to finish!
