9 Things to Check Before Calling HVAC Contractor

1. Checking the AC's circuit breakers

Power switches and breakers are frequently accidentally turned off when installing new 

appliances. Check your circuit breaker to ensure it's not something as simple as resetting a 

switch. A circuit breaker might be found in the basement, hallway, or storage room in some 

homes.

2. Examine the air conditioning Filters

Filters of any HVAC system are delicate. When troubleshooting an HVAC system, vents, ducts, 

and grills should be checked for blockages. Keep plants and furniture away from HVAC filters.

3. Check the AC: Property Manager

If you require an HVAC specialist, tenants should contact their property manager first before 

calling a technician. HVAC professionals arrive and discover they can't repair without 

the owner's authorization.

4. Check the HVAC Electricity Outages

Before contacting an HVAC contractor, make sure there's power. It's not always easy to spot 

commercial properties during business hours, although this is often the case. Natural illumination 

during the day is a cost-effective option for homeowners and renters.

5. Check the AC System Batteries

Clogged vents, for example, might block airflow and inflict irrevocable harm. The remedy may 

be as simple as changing your batteries. This HVAC troubleshooting method is commonly 

overlooked! If the thermostat isn't working, change the batteries.

6. Check the Outside AC Unit

It's not uncommon to overlook an outdoor unit when inspecting an HVAC system. However, the 

outside unit is the principal source of airflow within a building. Sucked onto the surface, leaves, 

and branches may cover the entire unit. After turning off the electricity, property owners can 

rinse the device with a hose to remove any leftover particles. 

Keep a 3-foot debris-free zone to maintain healthy airflow and avoid future issues.

7. Check the AC Summer frost

Pipes that have frozen due to abuse may cause cooling system issues during the summer. To 

troubleshoot HVAC, homeowners must defrost the system, which can take up to two hours. 

It is important to note that it may re-freeze once the system has thawed and restarted. This might 

go on for a few days. However, if this continues for several days, we recommend calling a 

certified HVAC Contractor. Turn off the thermostat but turn on the FAN to efficiently defrost the 

system.

8. Checking the AC Problems

Please don't turn the heat down, no matter how hot it gets outdoors! You may cause additional 

problems by causing the system to freeze, rather than a cooler house or company. Knowledge of 

air conditioning is beneficial. Your home's inside and outside will always be 20 degrees apart. If 

the temperature outside is 92 degrees, the average interior temperature is 72 degrees. However, if 

the temperature is over 100 degrees, the unit may have trouble cooling the property.

9. Examine the wiring of the AC system.

Cleaning up weeds in your yard can affect your HVAC system. Be careful when using a weed 

whacker near an outside unit, as it can damage cables. As you approach the device, look for any 

stray cords. Contact a local HVAC specialist if you discover any while troubleshooting your 

HVAC system.

Note: When the temperature outdoors becomes too hot, residents should close the drapes and 

blinds on the west side of their property. Close the curtain while troubleshooting HVAC systems 

to keep them working smoothly and efficiently for years.
