HVAC Inspection Service

Buying a home. You need to have the HVAC system inspected.

According to Home Warranty, 50% of the claims they pay are on home heating and air conditioning systems. Part of the reason is those home buyers assume that the home inspector has tested their heating and air conditioning equipment. But the home inspector may simply turn on your furnace and air conditioner to make sure they work. Even if the furnace and air conditioner appeared to be functioning, there may be an underlying problem that the home inspector cannot see (such as a cracked heat exchanger.) If you look at your inspection report closely, you will likely see a disclaimer from the home inspector that states he/she is not an HVAC expert and you should get a separate inspection. Buying a home is a major investment, and it’s one that comes with plenty of expenses, as every homeowner can attest. But one of the biggest investments within your home is the heating and air conditioning system. A new furnace and air conditioner can cost in the thousands while other appliances (like your oven and refrigerator) are much less costly. So it makes sense to get your HVAC system checked out ahead of time to know what you’re getting into. An HVAC inspection takes just a little bit of time and money and gives you a clearer picture of what to expect if you decide to purchase the home.

Need to get an air conditioning and heating system inspection for a home from a trusted HVAC company? Schedule with Dena Air.

We’ll take on any project, no matter how large or small. Call us today and see what we can do for you.
