Find answers to all your questions

What brands do we service?

Moncrief is a Carrier Factory Authorized Dealer. However, we service all brands, makes and models.

What type of filter should I use?

Standard fiberglass 1” filters are the best for airflow, efficiency, and system capacity. Using more restrictive pleated filters reduces air volume going through the system – making it harder for your system to heat/cool your home. If you want improved filtration, we recommend a high-capacity media air cleaner designed to work with your system.

Why and how often should I have regular preventive maintenance done?

The system that heats and cools your house requires regular, seasonal maintenance to perform optimally. Components need to be cleaned, inspected, and replaced over time to ensure the reliability, safety, and efficiency of the system.

What does my warranty cover?

Under the standard factory warranty, Carrier covers parts that fail during the warranty period. The warranty does not cover labor after the first year. Some components carry more warranty coverage than others. This is based on the specific model/serial number and installation date of your system. Please call Moncrief for detailed information. With a Moncrief Total Comfort Service plan, you’ll have full coverage of parts and labor on all your system repairs.

What is the life expectancy of my system?

Life cycle of an HVAC system depends on many variables: proper installation/sizing, routine maintenance, usage, location, and acts of God (lightning, rain, flood, fire). To ensure you get the most out of your system, get signed up for the Moncrief Total Comfort Service Plan, which will ensure the system is properly cared for.

Is it normal to add refrigerant to my system?

Yes and no. HVAC systems tend to leak over time due to the normal wear and tear on a system. Leaks can also occur for other reasons. You should not have to regularly add refrigerant to a system, however. If your system is found to be low on refrigerant, a technician can leak check the system to determine the source of the leak. It may be repairable, or it may signal the need to replace a component of your system.

What does our Diagnostic Charge include?

The diagnostic charge gets our technician, in a fully stocked vehicle, to your home to troubleshoot a problem with the system. Once the problem is determined, our technician will let you know the issue(s) and costs of additional repairs. We do not waive the diagnostic fee with repairs. Other companies may do this, but rest assured they are recouping the fee in their repair costs

Why can't a leaking coil be repaired?

In most instances, leaking evaporator coils are not repairable. This is because the metals are corroding and breaking down, and the holes are numerous microscopic pinholes packed into dense layers of aluminum fins and copper tubing. In some instances there is a specific leak source that can be repaired. Also, depending on how old a component is, the cost of a repair may approach the replacement cost of a new component. A technician can determine whether or not a leak is repairable.

Can you provide exact appointment times?

Moncrief has plenty of flexibility to work with our customers’ schedules. The day is divided into three-hour windows to allow for traffic and other unexpected events. We always call ahead to let you know when we are on the way. We can also contact you on your cell phone or text message so that you do not have to wait at home for our technician to arrive.

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

There is no true correct answer to this question. However, using the fan “ON” mode has been shown to increase levels of humidity during the summer. Additionally, air leaks in the duct system may cause additional infiltration while the fan is running.

Does Moncrief do plumbing work?

Yes! We offer limited plumbing services. We provide gas/electric water heater and water filter service/installation. We also service and install boilers and tankless water heaters.

Should I get a bigger air conditioner or furnace?

Generally speaking, no. According to the National Comfort Institute, the average HVAC system is operating at 40-60% of its rated capacity. There are many reasons that contribute to this fact: insufficient ductwork, poor airflow, poor installation, etc. While, installing a bigger A/C seems like the logical way to make a home cool better, there are often much better ways to get more capacity and efficiency out of your existing system. When it comes time to replace your system, Moncrief’s Installation Engineers can design a system that is sized properly and, most importantly, installed correctly so that your home gets the most out of your new system.

What is a variable speed system?

“Variable speed (VS)” is the term the HVAC industry uses to describe the blower motor in your furnace or air handler. Variable speed blowers ramp up and down slowly, creating a more gentle on/off cycle to your system. Carrier Infinity products take full advantage of VS technology, with the ability to slow the blower down to help dehumidify, if needed. They can also match system staging and be adjusted for customer preferences. Most importantly, VS motors will ramp up to overcome restricted duct systems or dirty filters.

What is multi-stage equipment?

HVAC technology continues to provide homeowners with increased comfort and efficiency. “Staging” is one way they are able to do this. Staging refers to a system’s ability to ramp up or down output to match condition requirements. If it’s a mild day, for example, the system will use low stages to save energy and improve comfort rather than cycling on/off rapidly like a single-stage system might. Conversely, if it is really hot/cold or you want to change the temperature a few degrees, the system can ramp up to higher stages to more effectively condition your home.
