Frequently Asked Heating Questions

What is the difference between a heat pump and furnace?

Both a heat pump and a furnace turn a source of fuel into heat. A furnace, which is inside your house, takes natural gas or propane fuel (or electricity) and turns it into heat. It then sends that heat through the ductwork in your house with it’s fan.

Heat pumps, which sit outside your house, use electricity to pull heat out of the outside air. The main source of your heat is the air, and air is free! Heat pumps are fantastic because they provide both heating and air conditioning for your home. While there are many energy saving benefits to owning a heat pump, it is important to understand that the heating capabilities decrease when it gets to be freezing outside.

Fortunately, Washington State residents face these climates rarely. This makes heat pumps ideal for the Seattle area. For times when it does get colder, a back up gas furnace or electric air handler will ensure year round comfort.

When looking into furnace replacement, consider adding a heat pump to your natural gas furnace to make it a hybrid system. It’s is great way to obtain optimal efficiency, low energy bills and comfort. Still wondering which system is right for you, here’s more information on making that heating system decision.

Am I ready for a furnace replacement?

Furnace replacement timing in homes today is roughly between 16-20 years. Your old furnace may still be running after this time but not very efficiently and thus using more energy and costing you money. In addition, your furnace may decide to call it quits any day leaving you with no heat. Other common signs indicating a need for furnace replacement are strange noises such as popping, banging, rattling or squealing furnace noises. If you hear your furnace blower turn on excessively or blow cold air out at times, that is a good signal that you should consider furnace replacement.

What is a hybrid heating system and how does it work?

A hybrid system is the combination of your heat pump and furnace working together to provide maximum energy efficiency and year round comfort. Known for their efficient and cost saving operation, a heat pump will work as your primary heating and cooling source throughout most of the year. When it gets too cold outside for the heat pump to produce sufficient heat for your home, your furnace will automatically kick in to save the day. That way, you can always ensure a comfortable & energy efficient home.

My home doesn’t have ducting installed, what are my options for a heating system?

You have heating options; converting to gas and installing ducts which would be required for a new gas furnace or hybrid system, or installing a ductless heat pump, which is an efficient electrical heating system, or using alternative heating methods including gas fireplace insert (yes they heat), and/or a freestanding stove.

The installation of ducts alone is typically costly once considering the layout, number of vents and permits needed. Duct work can cost thousands of dollars before even purchasing the new heat pump or furnace it was intended for. Fortunately, ductless heat pumps can be installed into your home without the need for ducts. Ductless heat pumps are powerful enough to heat AND cool your entire home as a primary heating and cooling source. There are significant rebates available for adding ductless split systems to your electrically heated home.  

Is a ductless heat pump a good fit for my home?

Ductless heat pumps are an ideal alternative to electric heat or for additions and other areas of the home that may not have adequate ductwork. Converting from baseboard heat to a ductless heat pump can save homeowners 20-50% on their electric heating bill. Plus, no duct work is required for operation. Even better, you may be eligible for utility rebates up to $1200 for converting from electric to ductless. Ductless heat pumps are available in single zone and mini split systems allowing for sufficient heating options for a variety of home sizes. We install ductless systems in single family homes, condos, and up to 4-plex multifamily homes. 

What is the difference between AFUE & SEER?

AFUE & SEER are national standards used to measure the efficiency of your home heating (AFUE) or cooling (SEER) equipment. This is for all home heating and cooling equipment from furnaces, to energy efficient hybrid heating systems that combine a furnace with a heat pump, to ductless electric heat pumps.

AFUE (Annual Fuel Utilization Efficiency)

Heating equipment, tankless water heaters and boilers come in several levels of efficiency, for example 80% 90%, 95% AFUE and up to 98% AFUE. Anything that heats with natural gas or propane will be rated using this basis. AFUE tells you the amount of heat you get compared to the amount of fuel (natural gas or propane, typically) that you put in. So 80% AFUE means 80% of the fuel becomes heat and 20% is wasted. With gas bills going up, it can pay to have a 95-98% furnace – you could lower your heating costs by 15% or more.

SEER (Seasonal Energy Efficiency Ratio)

The SEER rating of a unit is the cooling output during a typical cooling-season divided by the total electric energy input during the same period. It is an equivalent measure of ability to produce cooling using electricity. Why is this on the heating page? Because heat pumps and ductless heat pumps both produce heating and cooling and are electrically run systems. So when you investigate heat pumps, you will see SEER ratings. You will also see HSPF (Heating Seasonal Performance Factor), which is the heating output rating for heat pumps.

What is an HVAC contractor?

HVAC stands for Heating Ventilation and Air Conditioning. Washington Energy Services is an HVAC contractor. This is essentially the same as a heating contractor. The ventilation part of HVAC is very important. Ventilation includes your ducts, proper venting of heating equipment, air returns and ensuring the flow of air through your home is safe and proper. When choosing an HVAC contractor, make sure they keep your ventilation in mind.

Most qualified HVAC contractors, such as Washington Energy Services, are members of ACCA, the Air Conditioning Contractors of America. Although they have air conditioning in their name, this is an association that represents both heating and cooling issues, and is a strong advocate for the setting of codes and standards, government policies and is a source of best practices. Washington Energy Services is proud to be an ACCA member.

What makes for the right Seattle heating installation?

It takes skill and careful preparation to properly install heating and cooling systems. We call what we do, custom installation, because every house is different and we want to get your particular install done right. Our HVAC teams have many years of experience and training to be able to overcome any challenges. Challenges such as unusual locations, transitions between the unit and the ducts, and making it as aesthetically pleasing as possible. It’s unpredictable what they will face on each job so they have to be ready. This is especially true in old Seattle heating systems where often the houses have been remodeled many times over their lifetimes. The ability to diagnose and execute in any given situation is their talent.

BTU? AFUE? What does it mean? Common Terminology of Heating Explained

Like any technical field, there are acronyms in the heating and cooling industry. As a heating contractor, it’s our language, and hope we can translate some of the common ones for you into layman’s terms. Our home energy specialists can always provide a more in-depth explanation. Enjoy!

  • AFUE: Annual Fuel Utilization Efficiency. This ratio represents how efficient your furnace is at using fuel and converting it to heat. An older furnace might have an AFUE of 80, but after many years be running at 70. That means 70% of the natural gas it burns is becoming heat and 30% is wasted. The new generation of furnaces, such as the Bryant Evolution 987M, convert 98.3% of fuel into heat, saving you energy and money.
  • BTU: British Thermal Unit. The BTU is used in heating to express the amount of heat that the heating system creates when it burns fuel. It’s actually the amount of power needed to heat or cool a pound of water by one degree F. Or coincidently, the heat that burning a four inch match puts out. This long time measurement has stuck around as the standard for heating equipment. A related measurement is BTU/H or btu’s per hour. This is often applied to heating and water heating equipment. Most furnaces have a rating of between 60,000 and 120,000 BTUs.
  • EAC: Electronic Air Cleaner. This is a device that is an alternative to a furnace filter. Your EAC filters out large particles and cleans your indoor air using electro-static charge. It magnetizes the little particles, viruses and bacteria, pulling them onto a plate, that you can clean. The homeowner can remove the plate and wash it periodically to ensure proper functioning, similar to changing a furnace filter. The EAC is part of the heating system and is connected to your furnace or air handler.
  • HSPF: Heating Seasonal Performance Factor. This measurement marks the heating efficiency of a heat pump. The higher the HSPF, the more efficient the heat pump is at heating your home. The measurement is actually a ratio of the BTUs of heat output that the heat pump provides, divided by the electricity used to run it. The main purpose of this measurement is to give you a way to compare the energy efficiency of heat pumps. The most efficient heat pumps today are in the 18-20+ HSPF range. The basic standard is 13 HSPF.
  • MERV: Minimum Efficiency Reporting Value. This is a comparison of the efficiency of a furnace filter. The scale goes from 1 (the lowest efficiency) to 16 (highest efficiency). This tells you the relative ability of your filter to remove particles from the air.
