Depending on what you are replacing, your heating bill can decrease by 18 to 40% if the installation is of a much greater efficiency unit, properly done and the system is accurately set up. That saving can add up to quite a lot over the years and you just may save a part of the environment through less energy use.
During operation, a heat pump outdoor coil is quite cold and below about 45 degrees outdoor temperature a heat pump coil is cold enough to form frost, as it is absobing heat from the outdoor air.
As the heat pump continues to operate the entire outdoor coil should form a frost evenly covering the coil. At the correct point in the cycle it will go into defrost. The fan will stop, the reversing valve will switch, the hot refridgerant will melt the frost away and water will run off the coil. When defrost is complete the reversing valve goes back to the heating position, the fan starts and we are heating again.
This is a normal operation.
If the coil frosts unevenly, does not defrost completely, or thick frost or ice forms – it is not normal operation. You should call for service so you can get your efficiency back and not damage the heat pump compressor and coil.
In the HVAC industry, late winter and spring is a good time since work is traditionally slow and all contractor need work to keep the installers busy. This time of year prices come down to help generate more work and you can get the best prices.
There are no longer any tax credits for furnaces or air conditioners. There is a tax credit for geothermal heat pumps and solar. There is an Idaho tax deduction for high efficient equipment and wood stoves replacing less efficient units. It is complicated and you should call for a comfort adviser to explain what is available for your situation.
Over the years, most flues need part replaced above the roof. This is where condensation occurs and the pipe will disintegrate. Call a technician to check out the entire flue and repair. This may be a good time to have your furnace tuned up if you haven’t.
This depends on what is creating the noise. If there is vibration, scraping sound, banging on and off, some adjustments should solve the problem. If you are hearing actual blower noise, a sound baffle might work. Most burner sounds cannot be fixed and a new, quiet furnace may be in order.
If you get a hum or a varying “tuning fork” sound, look to your return grilles. If you can place your hand against the grille and stop the noise, you have too much air going through the grille and need to have it enlarged or have another one installed.
Water by your furnace at any time is a bad thing!
If you have a condensing furnace and water is present during the heating season, there is a leak in the condensate system that may be damaging the furnace. If there is water during the cooling season, the cooling coil drain is plugged. Either way the drain problem must be corrected. If you need help, please call and one of our technicians can solve the problem.
The R22 refrigerant we have had for as long as anyone can remember is being phased out because it may harm the environment. It will still be available for service on older equipment for the foreseeable future but will be progressively more expensive.
The new R410A refrigerant has been available for new equipment for several years and has been a requirement for all newly manufactured equipment since 2014. The refrigerants do not mix and are not to be interchanged.
