You should not need to regularly add refrigerant to your system. Air conditioning systems do not use up refrigerant like a car uses gas. If your system is low on refrigerant it means that it has leaked out or was not charged correctly to begin with.
There should be a label on your air conditioner close to the model number.
R-22 is a refrigerant that was used in most residential air conditioning units prior to 2010. It has been determined that R-22 depletes the ozone layer and so it has been scheduled by the EPA to be phased out. On January 1, 2010 manufacturers were banned from manufacturing equipment containing R-22. R-22 is still produced to service existing equipment, but is tightly controlled by the EPA. On January 1, 2020 chemical manufacturers will no longer be able to produce R-22 to service existing air conditioners.
“Freon” is the brand name of a refrigerant. It is often used generically just like “Kleenex” is often used to refer to any brand of tissue.
This can depend on the age of your system, the refrigerant it uses and the size of refrigerant lines required for the new air conditioner.
It depends on individual circumstances. It can be as simple as replacing the outside unit, or could require replacement of the indoor coil and furnace as well.
Your air conditioner is a personal preference and an investment, so the final decision is yours concerning repairing or replacing your system. Our job is to give you detailed, honest information about the costs and benefits of your various options. At Mark Hill Heating & Air, we take this part of our job very seriously. Whatever option you choose, we want to be your heat and air service provider for life. We’ll give you our expert opinion and recommendations based on our decades of experience. But, you’ll experience no sales pressure from us. Instead, we will ensure you are educated in your decision.
There are many reasons homeowners might decide to replace an air conditioner. The most common reason is that they decide a new system will be more cost effective than repair. Homeowners might also replace an air conditioner if they want to increase efficiency, want a more comfortable system, want a quieter system or want a more reliable system.
A compressor is a major component of your air conditioning system, located inside the condenser. It moves the refrigerant through the system.
The outside air conditioning unit is often referred to as a condenser, which is made up of coils and a fan. This unit rejects the heat that is brought by the refrigerant from the inside of the house.
An evaporator coil is part of the cooling system. It is attached to the furnace cabinet and will often look like part of the furnace. The evaporator coil is attached to the air conditioner by copper refrigerant lines. The refrigerant cools the fins of the evaporator coil, which cools the air as it passes through the coil and into your duct system.
You are not required by law to repair it. But, we always recommend finding the leak and making the repair. Your system will not be running efficiently if it is undercharged. An undercharged system could also damage your equipment and you will have the continuing cost of adding refrigerant.
Replacing only the AC portion of your system can be an option, but if the indoor coil is involved or your furnace is old, it can often be more cost effective to replace your whole system.
It is possible your indoor coil is frozen, blocking airflow to your vents. A common cause of this is dirty filters. You could also have a malfunctioning blower motor or collapsed ductwork. All of which should be inspected by an HVAC professional.
Premium pleated filters can do a good job filtering small particles, but can reduce airflow and make your system inefficient. This is called pressure drop. Cheap fiberglass filters have less pressure drop but can let smaller particles through. We sell a middle of the road pleated filter and washable electrostatic filters, but we highly recommend Trane® Clean Effects™. Clean Effects™ has the lowest pressure drop with the highest efficiency possible.
Find sources of dirt and dust and eliminate them. Holes in ducts can suck dirty attic air into your house. Vacuum and dust on a regular basis to remove dust that does get into your home. Install an efficient filtration system. Monitor the humidity level in your home. A variable speed furnace will allow the fan to circulate the air constantly at a lower cost, filtering more particles from the air.
Particles like dust, smoke and bacteria are often .3 microns or less in size. At that size, allergens can get deep into your lungs because they aren’t filtered well by your nose and throat. An effective whole-house air cleaner, such as Trane® CleanEffects™, can reduce the presence of potential asthma and allergy attack triggers in your home, like dust, pollen, pet hair and dander, dust mites, mildew, lint, fungus, most tobacco smoke, cooking grease and even bacteria.

We do not service floor furnaces. However, we can give you information about upgrading your system to a modern, more efficient one.
Variable speed furnaces allow for longer run times, increasing the efficiency of your system and the overall comfort in your home. Variable speed motors can also run constantly at low speed (at very low energy cost), which improves the air quality in your house.
Sometimes the problem can be solved by something as simple as replacing the batteries in the thermostat, replacing the air filters, or even plugging in the furnace. These are some of the things you can check before calling for service.
Simply call a Mark Hill Heating & Air Comfort Consultant. Our Comfort Consultants come to your home to assess your needs and help you discover the system that is perfect for your home and your budget.
A properly maintained furnace should last 15-20 years. Regular maintenance is the most important factor in prolonging the life of your furnace. However, many other factors can impact a furnace’s lifespan.
ONG is offering rebates for improving the efficiency of your furnace and for switching from electric to gas. See www.oklahomanaturalgas.com/SaveEnergyAndMoney/EnergyEfficiencyProgram.aspx for more details.
The least efficient furnaces sold today are 80 percent efficient. If your furnace was manufactured before 1992 it could have an efficiency rating as low as 65 percent. We sell furnaces that are up to 97 percent efficient, which are better for the environment and can save tremendously on energy costs.

Our job is to give you detailed, honest information about the costs and benefits of your various options. At Mark Hill Heating & Air, we take this part of our job very seriously.

This is called short cycling. One of the most common culprits is dirty filters. Dirty filters cause heat to build up in the system causing the furnace to shut off. Thankfully, this is an easy fix. However, faulty thermostats, dirty flame sensors, clogged vent pipes, and mis-sized equipment, can also cause short cycling. The bottom line is, short cycling can be a sign of a serious problem and we recommend you call an HVAC professional.
Yes, we permit all of our installations.
We will arrive between 8:30 and 9:00 on the day of installation. Special arrangements can always be made if we need to arrive at a different time. Our installers will call before leaving the office.
We are required by the EPA to recover and recycle refrigerant.
The more notice you can provide, the better. We are often able to accommodate emergencies by replacing the equipment the same or next day. However, more notice allows us to provide the best service to all customers.
Most system replacement installations take one full day. Duct system replacements and complicated replacements can take longer.
There are many different models and combinations of equipment to serve your unique needs. Therefore, we must evaluate your home, your existing equipment and your personal needs to determine your options for a new system. There is never a charge for a replacement proposal.
The timing of the service is not as important as the routine. Once you establish a maintenance schedule, stick with it.
You receive a 10% discount on repairs.
We recommend having a tune-up every 6 months.
Maintaining new equipment is just as important as maintaining older equipment. Also, maintenance is an important part of keeping your warranty in effect.
We do not include filters because of the multitude of sizes and types. We are happy to provide filters at additional cost, but do request pre-notification so that our technician can have them on his truck for your service. Keep in mind, your filters may be washable and reusable.
We have included maintenance tasks that most people need every year in order to keep costs down. Cleaning an evaporator coil or blower wheel can be an extensive maintenance task and should not be needed if filters are changed on a regular basis.
