This is an easy one.  Yes it is!

I know that spending money in these economic times is not fun.  Especially on a piece of equipment that you use maybe  3 to 4 months a year in Minnesota.  However, it is the fact that we live in Minnesota that makes it even more important to have your air conditioner serviced every year.

Your air conditioner works by cooling refrigerant that circulates between a coil that sits in ductwork above your furnace and the condenser that sits outside your home.  The idea is that heat is removed through this process by the big fan in the condenser and the coils in the condenser. Blockage of the fan or the coils causes a reduced air flow which does not allow the refrigerant to cool which causes the a/c to overheat and shut down or not reduce the heat in your house.

One of the ways Minnesota has an effect on your air conditioner is a result of cottonwood trees.  Cottonwood trees start shedding in May or June.  You probably don’t see the trees but, see cotton like floating things which make it look like it is snowing.  These tend to get sucked into the outside of the a/c condenser covering the tiny coils.  Leaving the coils covered will have a huge impact on the effectiveness and life cycle of your air conditioner.  Even brand new air conditioners are effected by this. The condenser will be starved for air and you can actually feel how hot the air is if you put your hand above the a/c condenser.

Another way MN has an effect is the little amount of time you use your a/c.  The most demanding use of the a/c is when it turns on.  In Minnesota, this happens a lot.  The air conditioner will come on and cool the house and then shut off many times.  Unless we are in the 90′s and humid the a/c is not required to run non stop.  We are just the opposite of states located on the west coast or southern part of the country.  In those states the furnace behaves like our air conditioners if they have a furnace.  It is very important that you have the proper refrigerant in your a/c.  Proper refrigerant levels will help protect the compressor when it is turning on and does not have any fluid moving.  Sort of like engine oil in your car.  Proper refrigerant levels will also prevent the coil inside the house from freezing up which prevents cooling and could cause water leaking into your furnace.  (This is another subject totally as to why this happens.)

The third way MN has an effect,  is the air flow that is going over the coil can cover the coil with lint, dust or anything that the filter in your furnace that runs 6 or 7 months of the year doesn’t catch.  Cleaning this coil will help the efficiency of your a/c by making the metal exposed to the air flow instead of being covered in a blanket of lint and dust.

So in review, YES, is the answer to Is Cleaning and Servicing My Air Conditioner Needed Every Year in MN.  It is important that you have the following done every year:

  • Have the condenser that is outside your house cleaned.
  • Check refrigerant levels and pressures.
  • Have your A coil that is in your home and sits above your furnace check or cleaned.

You will save big money if you do this every year in the spring by hiring a contractor while they are running specials.  Or an even better deal is signing up for maintenance plan like our Service Partner Plan.

I received a call yesterday from a homeowner who had a new air conditioner installed by another HVAC contractor in his Coon Rapids, MN home.  He was concerned that it was not keeping his main level cool and his basement was freezing.  I asked him if a heat calculation was done one his home to make sure the air conditioner was sized correctly.  He said something that I hear far too often from homeowners who have other hvac contractors perform new installs.  His response was “I don’t know.”

The homeowner had a rambler with older windows and a big patio door in a room that faced south.  He said he was unable to get the temperature on the main level to a comfortable level.  He had a 2000 sq ft home with a 2 ton a/c.  While this may have been the right size for a  a 2 story house with new windows it is not satisfying his application.  That is why a heat calculation on all new installations is critical.

A heat calculation that is prepared by the person performing an estimate is a best practice  procedure.  Some cities including St. Paul and Minneapolis require it before approving a permit for install of furnaces and air conditioners.  A heat calculation is used to see how much heating or cooling your house needs based on many calculations including, size of home, windows, levels, duct runs, insulation factor.

In this instance, the house had a long run of duct work due to being a rambler.  The air is not reaching the ends of the house.  Another example of this would be a 4 level split.  The a/c may need to be larger due to the longer duct run and the need to increase the blower to push the air.  The faster the air moves the less cooling is coming out of the vent.  This results in the need of a larger a/c unit and coil to make sure the air gets to the cool level that is required.

Bottom line is that a heat calculation is needed to take into account exceptions to the perfect install.  Ask the salesmen who are visiting your home if they are preparing a heat calculation.  If they say no ask them how they will arrive at the right size equipment for your home.

Comfort consultants from Minneapolis Saint Paul Plumbing Heating Air will always do a heat calculation on your home before they will decide what is best for your application.

2010 concluded the $1500 tax rebate for upgrading your furnace, boiler or air conditioner to a high efficient unit.  The federal tax credit ends on December 31, 2010 and you had to have your hvac equipment installed by that date.  That is the bad news.

The good news is that there is a 2011 Federal Tax Credit available.  While it is not as good as the one that finished in 2010, it is still money in your pocket if you were not ready to replace your furnace, air conditioner or boiler until now.

Some of the details are listed below:

  • The maximum amount an eligible homeowner may receive in tax credits for residential property will be reduced from $1500 to $500.
  • All furnaces and boilers, whether natural gas, propane or oil, must have an AFUE of 95 or above to be eligible for the credit.
  • The credit is not 30% of the total cost of the hvac equipment including install.
  • $150 Tax Credit for natural gas, propane, oil furnace or boiler with minumum 95% AFUE
  • $300 Tax Credit for split system air conditioner with minimum 16 SEER / 13 EER
  • $300 Tax Credit for split system heat pump or min split system  15 SEER / 12.5 EER / 8.5 HSPF

As you can see, the Federal Tax Credit is not as attractive in 2011 as it was in 2010 and 2009.  However, if you are looking to replace your lower efficient furnace, boiler or air conditioner, it may help cover the extra up front cost of the replacement while you save money on your monthly energy bills.

By now you have probably heard about the $1500 Federal Tax Credit for upgrading your home heating and cooling equipment to high efficient units.  However, do you know that you are running out of time to take advantage of  the opportunity?

December 31, 2010 is the last day that you can take advantage of the tax credit to upgrade your furnace, boiler, water heater or air conditioner from a less efficient system to a high efficient system.  The combination of the tax credit and money you will save in energy costs allow the quickest payback on your investment ever.

Below is a list of equipment and minimum efficiency required to qualify for the Federal Tax Credit.

Do not wait until the last minute to contact a HVAC contractor to have an estimate done to replace your old equipment.  Most licensed contractors are 2 weeks out on installs.  Be concerned about anybody who is not booked out that far on installs.

Minneapolis Saint Paul Plumbing Heating Air offers free in home estimates to help you sort through all the options and answer any questions regarding equipment or comfort needs.  You can schedule online or by phone.
