Four Tasks to Perform Before Turning Your Furnace Off in the Spring

Keeping a maintenance schedule for your air conditioner, furnace, and other HVAC equipment is an important part of keeping everything in working order. In this post, we will look at five tasks you should perform before you turn off your furnace for the spring and summer.Heating & Cooling in Kalamazoo

  1. Look over electrical connections

If you notice any fraying, loose wires, or anything disconnected, you should call an HVAC professional to come over and take a closer look. Do not attempt to handle or repair electrical components on your HVAC equipment yourself.

What is Geothermal Energy, and What are the Benefits?

Geothermal energy is a natural energy that comes from the hot rocks inside the earth, deep below the surface. To harness this energy, two holes are dug into the ground, one for water to be pumped through. As the water passes the hot rocks, it is transformed to steam, which comes out of the second hole and aids in producing electricity. The heat exchanger only uses electricity to move the heat, not produce it.

In Michigan, the temperature in the earth just a few feet below the surface remains at a 50-55 degrees Fahrenheit. So in winter, geothermal energy can be used to heat as tCapturehe earth temperature is warmer than the air, and in the summer geothermal energy can be used to cool as the earth temperature is colder than the air. To switch from heating to cooling, all you have to do is reverse the flow and temperature compression.

Temperature Regulation in Vacant Homes is Extremely Important

Everyone knows that a lot of money can be saved by adjusting your thermostat when you’re going to be out of the house on a short vacation or trip. But what should you do if you’re going on an extended vacation or you have a secondary property that is vacant most of the time? In this post we will discuss what you residential heating and coolingshould do that’s easier on your wallet and your property.

 A common mistake that homeowners make is thinking they can set the thermostat above 80 degrees in the summer and below 55 degrees in the winter. When a home gets really hot and humid during summer months, the high temperature and humidity can warp wood, strip wallpaper off the wall, and cause various other problems. In the cold winter months, too low of a temperature can mean freezing pipes and damage due to condensation.

Is it Better to Repair or Replace Your Broken Air Conditioning System?

Air Conditioning System

There are many things to take into consideration when deciding which option will better serve you. It’s not always an easy decision to make. It’s important to take your time and consider the pros and cons for your exact situation.

The first thing you’ll want to look at is the age of your air conditioning unit. If it’s more than ten years old, it’s probably time to really consider getting a new unit. They simply do not function as well as newer models. There is a good chance that the SEER rating is below the current standard, which means your unit does not have the energy efficiency that it should. A more efficient unit will certainly save you money on your monthly electric bill.

How to Protect Your HVAC System During a Major Storm

This past week the Kalamazoo area was hit with a major wind and thunderstorm with a tornado in the area. The first step in protecting your HVAC system during a storm is to protect your HVAC system before a storm. Typically, you know when a storm is coming, particularly if it’s a really bad one that could do a lot of damage. Lately in Southwestern Michigan, it seems like we’ve been having a couple of storms a week. Rain, wind, hail, and lightening are all factors that can damage your unit. Protect your unit this summer by following these tips:

  1. Prevent Against Flood Damage. Make sure that when your HVAC unit is installed, it is installed on a higher level, particularly if your area is prone to flooding (You can learn about floodwater heights in your area from the city’s building commission and in some cases online). If your HVAC unit is installed below the flood line, we can provide information about how to raise it. One more precaution to take is to make sure you have a sump pump installed which will automatically pump water out when the water reaches a certain level.
  2. Keep Your Yard Clean from Debris. One of the top two offenders of HVAC damage during a storm is debris that flies around in the strong winds (the other is hail). While you cannot protect your HVAC from something that may fly in from your neighbor’s yard, you can make sure the area around your HVAC unit is kept tidy. Prior to a storm, take your patio furniture inside to avoid hitting your HVAC (or creating other damage either to the furniture or house). Pick up the sticks and branches in your yard and make sure to check for dead branches in the trees that may easily come loose in the storm (and that may damage more than just your HVAC!)
  3. Do Not Use Your Unit During the Storm. Avoid electrical power surges (which can create massive damage in just a second) by turning off all heat and air conditioning at the thermostat. But even better yet is to switch off the circuit breaker that controls the units until after the storm is over.
  4. Cover and Secure the System. Make sure the HVAC system is anchored properly and consider covering the unit with a strong canvas tarp. You can also place hail guards over the more delicate parts of the unit.
  5. Inspect the Unit Before Turning it Back On. After the storm is over, go outside and inspect your unit before moving forward. Do not touch the unit if there are power lines down or near it. Make sure to clear out any debris, check for water around the unit, remove the cover, and change the air filter.

If after a storm you do notice that your equipment has been damaged, please give us a call rather than risking injury to yourself or risking further damage to the unit. We’ve earned a reputation in the Kalamazoo area for doing the job right the first time, so you can rely on us to quickly get your unit operational again.

Figuring Your Best Cooling Options by the Numbers

Bryant Air ConditioningWhat are you looking for in an air conditioner? Certainly you’re looking for an air conditioner big enough to cool your home efficiently, yet still economical enough to fit within your budget. So the first thing you should look for are the numbers.

Take a typical two-story home with interior space of 3,000 square feet.The cooling capacity for air conditioners is measured in tons. One ton is equal to the amount of energy to melt a one-ton block of ice in 24 hours. In our climate for Southwest Michigan, house inspectors roughly estimate that it takes 700 to 1,000 square feet per ton cooling capacity to be adequate. So if you’re the owner of this typical home, you’re looking for a central air conditioner of approximately 3 to 4.3 tons cooling capacity.

That’s a starting point, giving you a range of air conditioners that can adequately cool your home. The next number to look at is an air conditioner’s Seasonal Energy Efficiency Ratio or SEER number. The higher the SEER number, the higher the efficiency. As of 2006, a federal mandate required all new central air conditioning equipment be rated at least SEER-13, but current air conditioners can rate as high as 18, and some reach the low 20s.

Consumers Energy has an online tool that can help you translate that rating into an estimated annual cost for running your air conditioner. It’s based on the likely amount you would use your air conditioning during the cooling season for this region. You enter in the square footage of your home, the current cost per kilowatt hour (kWh) that you can find on your energy bill, and the SEER ratings of the models you’re considering.

Going back to our typical home with an electric rate of $0.13/kWh, purchasing a system with a SEER 13 rating will cost you $354 annually to run. If you choose an air conditioner with a SEER-16 rating, available in most of the central air conditioners Metzger’s Heating & Cooling offers from Bryant, the yearly cost estimate is $288.

If you choose an air conditioner with a SEER-21 rating, available in Bryant’s top model of its Evolution line, the cost is $219. That’s a savings of $135, or a savings of $1,350 over 10 years.

These numbers however, only get you into the ballpark. No one lives in a “typical” home. Even if your home has the same square footage, you also have to consider the energy efficiency of your home, including the amount of insulation you have, possible air leaks around windows and doors, and other conditions that affect energy use. Information on having a home energy audit done for your home is available through your power utility company, including eligibility for rebates when you improve your home’s energy efficiency.

The cost of a new air conditioner is the final factor, but can often be the deciding one. If you look at not just the purchase cost, however, but the use cost and additional savings you can realize if you improve your home’s energy efficiency, a high-efficiency central air conditioners may indeed be the best buy.
