Tips for Assessing HVAC Parts and Equipment in a New Home

Buying a new home is a big investment–avoid the mistake of being hit with hidden costs that could land in your lap soon after you move in.

A home’s HVAC parts and equipment are one of the most expensive purchases homeowners will need to make. Too often potential buyers neglect to make a thorough assessment of the condition of the HVAC system before making an offer.

Here are some tips on how to protect yourself and not get hit with a surprise repair soon after moving into your new home.

Start By Looking at the HVAC Parts and Equipment

A visual inspection will give you an idea of what kind of shape the system is in. If they look to be well maintained, it hints that the owner has a good track record of taking care of the home.

If there are any signs of rust, watermarks or damage, those are clues that the system may be getting close to replacement age. Most industry experts say you should start thinking of replacing HVAC parts and equipment after about 15 years.

Check for Duct Leaks

According to HGTV, 66 percent of homes have leaks in their air conditioning and heating system air ducts. You can check to see if there are loose connections or gaps in the air ducts.

Such leaks are costly to the homeowner. The U.S. Department of Energy’s Energy Star program notes that 20 to 30 percent of the air moving through the duct system can be lost due to such leaks. This forces your heating and cooling system to work harder, resulting in higher utility bills and inferior climate control.

Check whether the ductwork has any loose connections, visible gaps, torn sections, or other problems.

Note the Temperature Throughout the House

The farther a room is from the HVAC system, the harder it is to effectively manage its comfort level. But as you move throughout the house, there should not be a drastic difference from room to room.

Significant temperature differences, drafts, uncomfortable stuffiness, or unpleasant odors could be a clue that something is wrong with the HVAC parts and equipment, the ductwork or the insulation in the home.

Explore the Insulation

You will likely only be able to examine the quality of insulation in the attic of the home, but it is worth checking out. The floors, walls, and ceilings should be well covered with insulation. Any ductwork in the attic should also be well insulated.

Also, if there are parts of the house that are excessively hot or cold, it could be signaling an insulation problem. Places to pay special attention to are sunrooms, new additions or enclosed porches.

Ask Questions

Obviously, your best source of information is the current owner of the home. Take advantage of their knowledge while they most willing to share information–while they are trying to get you to buy their home.

It could help to learn more about how HVAC parts and equipment work before asking questions, and how to know when they are broken.

Some good questions to ask are:

  • How old is the system and what repairs have been done?
  • What is the brand and efficiency rating?
  • Is the unit still covered under any warranty?
  • Who is your regular service provider?
