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.

Great crew all around, owners, office, technicians. What I most appreciate is that everyone I dealt with was polite and professional. Secondly, they are trying to solve your HVAC issues, not charge you for things you don’t need. Highly recommend.

Michael was very responsive with initially setting up the service technician appointment. Alfredo was very helpful and a wealth of information. Our experience with everyone at A Custom was superb.

What is a Ductless Mini-Split System?

Unlike traditional central air conditioning systems, ductless mini-split systems do not require cumbersome ductwork. These advanced systems consist of an indoor unit and an outdoor compressor. 

The flexibility of these systems means they can be installed virtually anywhere in your home or office, offering a tailor-made solution that suits your unique cooling needs. When searching for a “ductless air conditioning installer near me,” A Custom Heating and Air Conditioning should be your first call.

Benefits of a Ductless Mini-Split System

Ductless mini-split systems offer several benefits over traditional air conditioning systems. Some advantages include:

Energy Efficiency 

Ductless systems minimize energy loss by utilizing inverter technology to adjust the compressor speed to match the cooling or heating demands of the room, resulting in substantial energy savings.

Zoning Capabilities 

Ductless systems offer individual temperature control for each room, meaning you only cool the spaces you use most.

Easy Installation

Unlike traditional systems that require extensive ductwork, ductless systems are simpler and quicker to install.

Quiet Operation 

These systems are whisper quiet, making them perfect for bedrooms, home offices, or any space where you desire tranquility.

Improved Air Quality 

With multi-stage filtration systems, ductless units reduce dust, allergens, and other airborne particles, providing cleaner and healthier indoor air.

Increased Comfort 

Enjoy precise temperature control and consistent comfort with a ductless mini-split system.

Signs You Should Replace Your Air Conditioner

Not sure whether it’s time to replace your existing air conditioning unit? Some common signs it may be time for a new installation include:

High Energy Bills

If your energy costs are climbing without a clear reason, it could be due to an old or inefficient air conditioning unit.

Frequent Repairs 

Regular breakdowns and the need for constant repairs can add up quickly, making it more cost-effective to invest in a new system.

Uneven Cooling or Discomfort 

If your system struggles to maintain a comfortable temperature or you’re experiencing hot spots and humidity, it’s time for a new unit.

Aging System

If your air conditioner is over 10 years old, it’s likely nearing the end of its lifespan.
