HVAC Inspections: What to Look for Before Buying

Most buyers glance over the HVAC system without realizing what’s at stake. If the system goes bad, you could be staring down a $10,000 mistake.

Quick Inspection Tips:

Check for rust or discharge from the condensate line, this means internal damage.
Inspect the unit’s placard to find out its age and warranty status.
Look at the system’s cleanliness. A dirty unit suggests poor maintenance and possible performance issues.

HVAC Efficiency: Is the System Costing You Money?

In Charlotte's hot and humid summers, AC efficiency is key to both comfort and cost savings.

Red Flags That Lower Efficiency:

Dirty filters or outdoor units lead to high static pressure and premature failures.
Wrong-sized units for the home can overwork the system and spike your utility bills.
Old or outdated systems lack the energy efficiency of modern models.

At Comfort Monster, their in-house software analyzes system efficiency to help you optimize performance year-round.

Red Flags During a Walkthrough

Even without a technician, there are red flags you can spot during a home tour:

Thermostat concerns: Is it Wi-Fi enabled? Does the home feel too hot, cold, or humid?
Inconsistent temperatures: Hot or cold spots between rooms often indicate deeper airflow issues.
Filter condition: A dirty filter suggests the homeowner hasn’t prioritized maintenance, which can spell trouble down the road.

Remember, a neglected filter not only reduces airflow but also taxes the unit—leading to high repair bills and reduced comfort.

Repair vs. Replace: What Makes Financial Sense?

Charlotte summers put a heavy demand on HVAC systems. So, how do you know whether to repair the unit or replace it entirely?

When to Replace:

The unit is older and out of warranty.
Major components like the compressor or evaporator coil have failed.
Energy bills are steadily climbing despite repairs.

When a Repair Is Enough:

Issues involve wear-and-tear parts like capacitors or contactors.
The unit is still within warranty and has a strong maintenance record.

Newer HVAC systems are more energy-efficient and include a 10-year parts warranty, making them a smart long-term investment.

Maintenance History: The Hidden Goldmine

Just like a car needs regular oil changes, your HVAC unit needs consistent upkeep. Unfortunately, most sellers can’t easily provide a full maintenance history, and that’s a missed opportunity.

What to Ask For:

Repair records and routine maintenance history.
Confirmation of regular filter changes and fluid checks.

Comfort Monster makes this easy with their mobile app, which stores all HVAC data in one place, accessible 24/7.

BONUS TIP: Don’t Forget the Ductwork!

Even if the HVAC unit looks perfect, the ductwork could be the hidden culprit.

Common Issues with Ductwork:

Poor insulation or sealing.
Conditioned air is leaking into unused spaces.
Uneven airflow throughout the home.

Instead of investing only in a high-end unit, sometimes replacing outdated ductwork and installing a mid-range HVAC system creates a more comfortable and efficient home.
