Rochester MN Home Inspector Asks: Is Your Air Conditioner ready For Summer?
Home Inspector Asks, Is Your Air Conditioner Ready For Summer?
Just like any of the other systems in our homes, our air conditioners need periodic inspection and maintenance to keep them running smoothly. We want the air conditioner to work when we need it right? Too often though, people wait until the temperatures soar to find out that the old unit just won’t fire up. Summer is coming and soon we will all want our air conditioners to run at peak performance to keep us comfortable. Careful inspection of the air conditioning system prior to peak use can help you to head off problems ahead of time.
First, the more you use your air conditioner, the more often it should perform an inspection. Filters are a good place to start. Cold air moves harder that hot air. If your air filter is plugged, the fan has to work harder to move the air. If the air isn’t moving, the air conditioner has to work harder to meet the desired temperature in the home. Buy a good air filter and make sure to change them at the manufacturers prescribed frequency.
At the condenser, (outside), make sure that there is adequate clearance for air flow around the unit. Three feet above and one foot at the sides, minimum clearance will allow the air to flow freely. Also, make sure that the cooling fins are free of debris and damage. If the fins are clogged with dryer lint or grass clippings, air can’t move freely through the condenser.
Catch small problems before they turn into big problems. Noisy condenser units could be anything from a loose screw on a panel or safety screen, to a loose fan blade. Loose fan blades could also be hitting part of the unit. If everything is tight and there is still a noise, it could be the condenser motor. You should call for service if this is the case. Make sure that the unit is sitting level to prevent unnecessary wear on the motor bearings.
Noise at the furnace could mean a bad motor or loose/worn drive belt. Again, you should call a service technician for repairs.

Rochester MN Home Inspector Discloses How to Cut Costs Efficiently, and Green up Your Home
If you have an old air conditioning unit, you may want to upgrade to a newer system that meets or exceeds the government energy standards. For example, it is possible to have savings of up to 47% on new heating and air conditioning costs with a newer model. Thanks to the American Recovery and Reinvestment Act, you may be eligible for tax credits if a new air condition and/or heating system meets energy efficiency requirements.
How efficient are your exterior doors? Old doors with poor seals may contribute to higher energy usage. New exterior doors usually fit and seal better than older doors. A new energy efficient door can help to stabilize your interior temperatures and decrease your energy usage.
Some other simple energy savers… Even small acts of green can make a difference. Turning off your computer and monitor when not in use; lowering the thermostat on your water heater to 120 degrees; taking short showers instead of baths and washing only full loads of dishes and clothes can all add up to big savings on your homes energy consumption.

Rochester MN Home Inspectors Unearth Dirty Furnace Filter
As a home inspector, I take the time to discuss the furnace filter with the new home owner during the walkthrough at their home inspection. It is crucial that you change your furnace filter regularly to help keep the air clean in your home. The filter in the picture above had to be at least a year old.
The filter is designed to remove the dust and particles from the air flowing in and through your home. A clean filter will allow the air to move freely. A dirty and clogged filter will cause the furnace fan motor to work harder to move the air. That along with poor air exchange will cause your yearly utility bills to be higher.
According to the company that replaced my furnace this year, the “blue, fiberglass looking” type furnace filter is the best balance for air flow and particle removal. The 1 inch thick accordion type filters do a great job of removing particles, but can plug up rather quickly. If air flow is restricted it will slow air movement as well as cause your furnace fan to have to work harder to move the air in your home.. Change your filter once a month to keep your furnace system running at its peak performance.

Home Inspectors Recommend Regular HVAC Cleaning
It’s getting cold and you are starting to close up the house for the season. Contaminants that are in your furnace, home, and duct work will circulate through out your home all winter long. Your HVAC (Heating, Ventilating, Air Conditioning) system can collect molds, fungi, dust, bacteria’s, pollens, and other allergens, that can cause irritation to some or all who live in your home. Believe it or not, the air in your home can be 2-5 times more polluted that the outdoor air according to the EPA.
Having complete inspections, cleaning and tune up done on your HVAC system can help to clean up the air in your home. Your system will run more efficiently, and in the end save you money on your yearly heating and cooling bills. A clean HVAC system also helps to increase air flow in your home, resulting in added comfort to you and your family.

Checking The Furnace Filter During Home Inspections
When inspecting a furnace during a home inspection, I typically find that most people do not change their furnace filters at regular intervals.
Replacing your furnaces air filter at regular intervals is the first step in keeping your furnace running properly. The furnace filter’s main purpose is to keep soot, dust, pollens and other particle contaminants out of the air in your home. Clogged and dirty air filters result in your furnace blower having to work harder. This makes your furnace more costly to operate and will shorten its lifespan.
Check your owner’s manual for the proper size and type filter for your furnace. Furnace filters vary in size, and it is important that you use one that is sized for your furnace. If you do not have access to the owners manual, you can sometimes find the filter information on the inside panel of the furnace. If the information is not provided on the furnace, you can try contacting the Rochester or Southeastern MN heating company that supports your furnace brand. Purchasing your furnace filters by the case changing more convenient.

Rochester MN Home Inspectors Recommend Maintaining Your Furnace
The attached video is from a home inspection I did recently in an older home where it was obvious that the home owner did a good job of maintaining their heating system.
There’s not a furnace out there that can, or will continue to operate efficiently without periodic maintenance. It’s important to keep your home’s heating system clean, lubricated, and properly adjusted. Replacing the filter regularly will extended life of your heating system and will help the furnace to heat efficiently. In addition, you will save energy and expense.
Ideally, your furnace should be inspected and serviced by a professional heating contractor on a yearly basis. It’s best to have the system checked before each heating season begins. Your local Rochester, and Southeastern MN utility and heating companies offer maintenance service at a reasonable price. If you do your own maintenance, you should have your heating system checked by a professional every three to five years.

Rochester MN Home Inspector Recommends Heating System Tune Up
The winter heating season is upon us here in RochesterMN area. When doing a home inspection and analyzing the heating system, I try to determine is a home’s forced air heating system’s age. If it is an older unit I suggest you have a professional heating contractor service it every year. If you furnace is newer, every couple of years should suffice. This is your best protection against carbon monoxide dangers and heating problems. Routine service will also ensure peak efficiency to save you operating costs.
A good service and inspection costs about $80-$120 and should include a complete cleaning, safety check, and tuning.
The service contractor should:
- clean the burner and heat exchanger, and inspect for cracks.
- tune the burners for proper combustion.
- perform a carbon monoxide test in the heat exchanger.
- check the vent pipe and draft diverter.
- inspect the chimney for obstructions and draft.
- check vent pipes for proper clearance and materials.
- test fan controls and safety controls.
- check the thermostat.
- run the furnace through a complete cycle.
- check flame roll-out.
- check gas pressure (if appropriate for your furnace).
- clean and adjust the pilot light assembly.
- inspect gas fittings and repair any leaks.
- lubricate the fan and motor.
- check belt condition and tension.
- service the filter.
- clean the fan and housing if excessive dirt has accumulated.
Replacing parts or cleaning extensively will cost extra.
You should have a basic understanding of how the system works, so if you aren’t clear on what is covered during the home inspection, ask the service contractor to explain the basics. You should routinely service the filter and lubricate the fan and motor a second time during the heating season. You should also inspect the flue connection to the chimney.

Rochester MN Home Inspector Recommends Regular Furnace Filter Maintenence
How often should you change the filter on the furnace? Whenever it’s dirty. And although it sounds a little silly, some of better filters get dirty more quickly and need to be changed more often.
A standard cheap (about $1) fiberglass air filter should be checked once a month and changed when it shows visible dirt. You also need to check the filter when running the central air conditioner, because air circulates through the furnace and the filter.
This home inspector recommends you do a little research befor buying a furnace filter. You will have to purchace a filter that meets your family needs. Read the labels-some are more efficient than others. Price will vary from about $3 to $15. These filters will trap much more dirt and smaller particles of dirt. They need to be changed more often because they do a better job of trapping dirt.
The next level up from standard throw-away filters are washable filters and electrostatic washable filters. Washable foam filters work quite well if coated with a special sticky spray like Filter Coat. Electrostatic filters are relatively expensive (about $100), but they do trap dirt well.
A better filter is the 6-inch-thick pleated paper filter. Air is forced through a long accordion of filter paper. Fine holes in the paper trap small particles of dirt. The large surface area limits pressure loss in the heating system. A special frame needs to be installed in the duct work, and the filter costs about $25, but it will last one or two years.
The top of the line is an electronic filter that charges metal plates in the air stream and attracts dust. This is the only type of filter that actually removes smoke particles from the air. This filter costs about $700 installed. Filter plates must be washed monthly in the dishwasher or by hand with soapy water.
I consider the pleated paper filters a good investment. The more expensive electronic filters are great for people with allergies or sensitivity to dust.
