Working with A Custom Services Inc, including the engineer Steve S. and Michael in their business office, was all positive and I will happily work with them again. They understood, made helpful recommendations, communicated proactively, and they followed through as they said they would. It was a stress free experience and good value for the work.

Alfredo and Tom replaced our furnace and did a Fantastic Job. They were professional, courteous and very informative. They were considerate of the delivery, prepping the area to keep it clean and worked efficiently and very quickly. Alfredo is a master HVAC professional and did a great job! Tom was fantastic on the installation as well as keeping my wife and I informed of the new aspects of the furnace and thermostat. Previous to the replacement Steve responded very quickly for the no heat call and was very professional to diagnose the problem and provide multiple solutions. Steve did an excellent job with the solution write up, planning for the hardware readiness and ensured that our project was completed the next day. Michael in the main office performed all the managerial interaction very well, answered all our questions and took care of the paperwork and invoicing in a very professional manner. Highest grades for this team and I will recommend them to all our friends.

A Custom Service was amazing throughout our experience with them. When I contacted them, Michael called me back promptly and helped me in scheduling an appointment. He also called a day before the appointment as a friendly reminder and to confirm that the appointment still worked for us. Alfredo was the technician who came to our house. He was on time and walked us through everything he was checking. He also answered all of our questions and even answered some questions my neighbor had about his system! He was very thorough, knowledgeable, and professional. After the service, Michael reached out again to make sure everything worked well. We used A Custom Service to do routine maintenance on our radiant heating system, and moving forward we will be using them to address all of our HVAC needs! Job well done.

Contacted A Custom Service to get some work done on my boiler. Response was quick, Michael was able to help me set an appointment up and was very attentive to our communications. Alfredo, our technician, was knowledgeable with boiler systems and was able to answer my questions. Found out that a circulation pump needed to be changed and he had the part in his truck so there was no delay in getting us up and running. A Custom Services will be our go to heating service from now on.

What Are Some Signs I Need Air Conditioning Repair?

Watch for these signs that something is wrong with your AC:

Warm Air from Vents

Warm air coming from the vents is a definite sign that you need to call our AC repair contractors. It could be an issue with the compressor or a refrigerant leak. 

Weak Airflow

Poor airflow is a sign that something is wrong with the motor or fan. It could also indicate a blockage. 

Frequent Cycles

If your unit is frequently cycling, it’s definitely time for a tune-up so the engine doesn’t overwork and burn out. 

Too Much Humidity

A working AC unit will regulate the indoor humidity. So, if you are experiencing muggy air inside, it could be an issue with your air conditioner. 

Water Leaks

An AC unit should never be leaking water. It could be refrigerant or a blockage in the lines.

Unusual Noises

Are you hearing banging or gurgling coming from your AC system? Don’t ignore these unusual noises. They are a sign that something is wrong in your unit. 

Strange Odors

Musty scents or odors of mildew are signs of an issue. Call our AC repair company in Evanston, IL, to check your unit for mold growth.

Steps to Take Before Calling Us

Some very minor issues you might be able to handle on your own. Before calling our AC repair contractors, try these tips:

Check Thermostat Settings

This sounds simple, but is your AC unit set to “cool.” Many times, we’ve shown up at a client’s home to find that their AC system wasn’t at the correct setting. 

Change the Air Filters

You need to replace dirty or clogged air filters. It improves air quality and increases your AC system’s efficiency. 

Clear the Area

Don’t stack belongings or have curtains near your AC unit. These block air inflow and impede the cooling process. 

Check the Circuit Breaker

No power to your AC unit? Check the circuit breaker. AC systems use a lot of energy and occasionally trip the breaker. 

Inspect the Drain

Check the condensation drain for blockages or misalignments. If your AC unit can’t eliminate moisture, it backs up within the system.
