Find answers to all your questions

What brands do we service?

Moncrief Heating & Air Conditioning is a Carrier Factory Authorized dealer. We also service well-known brands such as Rheem, Trane, Kenmore, and other popular brands of heating and air conditioning units. We officially recommend people who are looking for air conditioner installation choose a high-efficiency Carrier model.

What type of filter should I use?

The most important thing when choosing the type of filter is to make sure it’s designed for your system. Check your manufacturer’s guide or your owner’s manual for your HVAC system or furnace to see what kind of filter you should use. Generally, though, we recommend using a 1” fiberglass filter.

How often should I get HVAC maintenance done?

You should get HVAC maintenance done a few times per year. We offer air conditioner maintenance just before the temperatures start to rise, and heating maintenance when the temperatures begin to fall. Check out our Total Comfort Service Plan for more details!

Why should I get HVAC maintenance?

HVAC maintenance is important for two reasons. The first reason is because without maintenance, your system will suffer from breakdowns due to normal wear. HVAC systems are made up of thousands of moving parts and use a great deal of energy. Not only that, but they’re used all day. This results in wear due to usage. The second reason is because maintenance can uncover small problems that could result in much bigger problems later on. We offer a Total Comfort Service Plan which can help you save on the cost of maintenance!

What does my warranty cover?

If you own a Carrier unit, you should know that they cover failed parts during the stated warrant period. These are limited to manufacturer’s defects and will cover labor costs associated with them up until the first year. To get information on non-manufacturer specific warranty information, please call us at 404-350-2300.

What is the life expectancy of my HVAC system?

Each unit in your HVAC system has a different life expectancy. For example, you can expect an air conditioner to last between 10 and 15 years, whereas a furnace will last for more than 20. Your HVAC system’s overall life expectancy will depend on other variables such as whether it was sized correctly for your home, the relative climate of your home, and how often it’s used.

Is it normal to add refrigerant to my system?

No: in fact, refrigerant almost never needs to be added to an HVAC system for any reason. Refrigerant is not like fuel, where you need to continuously add more to keep the system operating. If your air conditioner doesn’t have enough refrigerant, it’s because there’s a leak in the system. Only once the leak is fixed will an HVAC technician add more refrigerant to your system. Not all leaks are repairable, though, and some will require a replacement part.

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 with all their tools 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

Why can't a leaking coil be repaired?

Leaking evaporator coils may not be repairable because the leak is caused by the corrosion of the metal tubing that surrounds the coil. If we find that your evaporator coil cannot be repaired, we will quote you for the cost of replacing the coil. In some cases, it may be more beneficial to replace the air conditioner unit entirely.

Can you provide exact appointment times?

We provide three-hour windows for appointment visits due to two factors. The first factor is to give you flexibility, so that you can choose an approximate time to be ready for us. Not only that, but some visits may take longer and we need to account for that. The second factor is due to scheduling around other visits. Our schedules need to be set up so that we can service all of our customers with the care and respect they deserve. By leaving room for flexibility in scheduling, we can better serve all our customers.

Should I leave the fan switch on "AUTO" or "ON"?

We recommend leaving it on AUTO for most purposes. If you are concerned about your own home’s ability to cool itself down, give us a call at 404-350-2300 and we’ll help you out.

Does Moncrief do plumbing work?

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

Should I get a bigger air conditioner or furnace?

The real question is, “Is my air conditioner or furnace correctly sized for my home?” If you’re not making large extensions to your home, you should never have to change the size of your HVAC components. But, some homes have HVAC systems that were not sized correctly. You will know this is the case if you have higher energy bills than you should despite feeling uneven temperatures throughout the home.

What is a variable speed system?

Variable speed is a term that describes how a blower motor changes speed. A variable speed system has a blower that speeds up and slows down slowly, rather than simply shutting off and turning on when it’s told to by the thermostat. The benefits of a variable speed system is that it provides greater humidity control and is more energy efficient overall.

What is multi-stage equipment?

Think of multi-stage HVAC equipment as having multiple settings, such as “low”, “medium” and “high”. Single-stage HVAC equipment simply has “on” or “off”. The aim of multi stage equipment is to provide a more comfortable home while staying highly energy efficient. You can tell whether you have multi-stage heating or cooling by looking at the wiring: if there is only one wire for heating and one wire for cooling, you have a single-stage system. If you have multiple wires, you could have one of several types of multi-stage HVAC systems.
