Frequently Asked Questions
Answers before the technician arrives.
Common questions about repairs, system replacement, financing, maintenance, and emergency service.
Why did my AC stop working?
Possible causes include a tripped breaker, worn fuse, failed compressor, refrigerant leak, clogged filter, or another mechanical issue. A professional diagnosis is the only reliable way to know for sure.
What are the signs I need AC repair?
Common signs include inconsistent cooling, musty or burning smells, banging or squealing noises, unusual buzzing, or a sudden increase in energy bills.
Should I repair or replace my AC?
It depends on the age, condition, and repair cost. If a system is more than 10 years old and the repair approaches half the cost of replacement, a new system may be the better long-term choice.
How often should I replace my air filter?
About every four weeks is a good rule of thumb, especially during periods of heavy use. A clogged filter reduces airflow and efficiency.
Do you offer financing?
Yes. Flexible financing options are available, subject to approved credit.
Do you offer emergency service?
Yes. TestCo Air and Heat offers 24/7 emergency HVAC service.
Are your technicians certified?
