Frequently Asked Questions

What Brands Do We Service?

We are a Trane Authorized dealer, which means we undergo rigorous training to become experts in Trane equipment. We officially recommend people who are looking for top of the line in home comfort use Trane systems. We also service and install other well-known brands such as Carrier, Rheem, Kenmore, and other common HVAC equipment brands.

What Does Our Diagnostic Charge Include?

To figure out the source of your problem, we run a series of diagnostic tests on your HVAC system. This requires a trained technician to run multiple tests to see what the issue truly is. The amount of time it takes depends on the true nature of the problem. Since this requires labor and tools, we have to charge for this service. Our diagnostic charges are not waived when we do repairs.

Can You Provide Exact Appointment Times?

We provide three-hour windows for appointment visits due to two factors. First, we want to give you flexibility, so that you can choose an approximate time to be ready for us. Plus, some visits may take longer and we need to account for extra time we spend with your equipment. Second, we need to manage our schedule and be available for all of our customers. By leaving room for flexibility in scheduling, we can better serve all our customers.

Does Moncrief Do Plumbing Work?

Yes! We have trained and certified plumbers on staff who can provide both gas and electric water heater installation and repair. We install and service both traditional and tankless water heaters.

What Type Of Filter Should I Use?

The most important thing is making sure your filter is designed for your system. Check your manufacturer’s guide or your owner’s manual for your HVAC system or furnace and see what kind of filter you should use. However, we generally recommend using a 1” fiberglass filter.
