Speaking of duel fuel, here is a new install.

Written: May 16, 2013

We recently had a customer in Beaverton with a 10 year old furnace and no air conditioning, and were looking for cheaper options to heat their home. After looking at their system, their home, and finding out exactly what they wanted out of their new HVAC system, we proposed a York heat pump with new York furnace. This duel fuel option will allow them to heat their home with a highly efficient, and relatively inexpensive heat pump most of the year. Then as the weather gets colder, the gas furnace picks up the slack.

We also installed a Honeywell IAQ thermostat with Redlink. This is a top of the line, internet enabled thermostat. With sensors in the supply and return duct work  the thermostat can notify you when your system is operating outside of normal parameters.

Rather than fabricate our duct fittings on site, we use a professional fab shop to produce our fittings.  This guaranties  a professional looking install every time.

If you are interested in a duel fuel system, please give our office a call. 503.650.1229 or use the contact us form and we will respond within 24 hours.

Customer Satisfaction

Written: May 15, 2013

We recently installed a new 96% efficient gas furnace with air conditioning for a customer in Beaverton. After each installation our customers receive a packet containing all of their warranty information and any other important documents. As well we always include a customer satisfaction survey.

While all the fives are great, what we really love are the notes that come along with them.

Duel Fuel

Written: May 14, 2013

Do you like to be comfortable? Do you like to save money? If so, a duel fuel system might be right for you.

Over the last few years there has been a lot of talk about the duel fuel option.  A duel  fuel option allows you to use a gas furnace on the coldest days and a heat pump to keep you comfortable the rest of the year.  Generally speaking, a heat pump is the most cost effective means of heating your home within certain temperature ranges. Once we fall below that range, you begin to lose efficiency and the cost to run your heat pump goes up and capacity diminishes. Before duel fuel, to meet capacity for your home electric strip heat would come on as a back up. Electric strip heat is very expensive though. Using natural gas to heat your home in these lower temperatures gives you a cheaper option compared to electric strip heat as well as a more comfortable heat for your home.

The three major components to a duel fuel system are the gas furnace, heat pump, and thermostat.  There are many furnace options these days from an 80% efficient single speed model up to a 98% efficient, variable speed system wit ha fully modulating gas valve. Depending on the level of comfort you are seeking most any style of furnace can be used in a duel fuel application.  Next is the heat pump.  The heat pump consists of a condensing unit outside the home an indoor coil connected to your furnace, and a line set to move refrigerant between the two.  In the summer a heat pump works like a standard air conditioning unit.  using the indoor coil to extract heat from the air in your home causing it to cool down. This heat is dissipated by the condensing unit to the atmosphere. When heating is needed, the compressor runs in reverse and extracts heat from the atmosphere via the condensing unit and dissipates that heat via the indoor coil to raise the air temperature of your home.  Lastly is the thermostat.  unlike a standard system, a duel fuel system will need a thermostat that can handle multiple stages of heating and sometimes cooling. The thermostat will also need an outside air sensor so it knows when to use the heat pump and when to use the gas furnace for heating.

Over the years Duel fuel systems have come down in price dramatically. 15 years ago, in order to achieve proper functionality you would have needed to install an extra set of controls called a “fossil fuel kit”. This kit was used to tell the system how to run. With the advancement of thermostats and connected sensors, these kits are no longer needed and the thermostat is able to control the show entirely on its own.  heat pumps themselves have also become more efficient. This means more money in your pocket. compared to a 7 SEER (Seasonal Energy Efficiency Rating) and a 6.8 HSPF (Heating Seasonal Performance Factor)  over the course of a year,  a new system could save up to $729.00.

Combine those annual savings  with state and federal tax rebates and up to $1000.00 off qualifying systems, and you can have a forward thinking,  highly efficient system for not much more than a standard furnace and air conditioner replacement.

If you are interested in more information or receiving a proposal to install a new duel fuel system in your home please give our office a call and we will be happy to assist you.
