Air Conditioning Installation and Replacement

If your air conditioner has reached the point where repairs no longer do the job or your home’s energy efficiency is at an all-time low, you may need a new system. When your Columbia home is ready for a new or replacement air conditioner, our Greenfox Cooling, Heating & Plumbing professionals will install your cooling system without delay.

How do you know if you need a replacement air conditioner? Here are some of the most common issues. Your unit is:

Approaching the end of its life span, usually between 15 and 20 years

Efficiency decreases as your system gets closer to the end of its life. You want to act proactively to plan what your replacement purchase will be instead of reacting when your system unexpectedly quits. This can save you money.

Experiencing more and more repairs

Similar to when your car requires more and more repairs, there comes a time for evaluation. Are you spending more in repairs than it would cost to invest in a new system? If the answer is yes, call and talk to one of our knowledgeable team members to discuss your options.

Showing signs of running inefficiently

How can you tell if your air conditioner is running inefficiently? A good indication is if your energy bills are increasing and your utility company’s rates remain steady. 

This typically demonstrates it’s taking longer for your heating, ventilation and air conditioning (HVAC) system to cool down your Maryland home to your preferred comfort level. Your system is running longer and using more energy than it should in this case—an increase in energy costs.

If you notice any of these signs with your air conditioner, or if you suspect another reason for needing a replacement, talk to one of our Greenfox Cooling, Heating & Plumbing team members. We will design a system best matched for your comfort needs and budget. Our experts are always here to help you.

Air Conditioning Repairs

Not having your air conditioner working on the hottest of days in Maryland can be exasperating. Whenever you need a repair, let our heating and cooling experts quickly remedy it for you.

There are many ways your air conditioner can stop working in its normal capacity. A few symptoms you could experience are:

• Hearing an unusual noise

• Feeling warm air coming from your vents

• Smelling an unusual odor like burning

• Noticing your air conditioner is frozen

• Leaking water

These symptoms mean you have an issue with your air conditioner. Ignoring problems usually only makes them bigger and more costly. Our recommendation is to have one of our Greenfox Cooling, Heating & Plumbing team members promptly diagnose and repair the issue for you.
