I had my entire HVAC system including all the ducting rebuilt by Coster Heating & Air. They did a great job and I'm more than satisfied. The work crew were friendly and courteous. The system works like a charm and now I have more than enough heat on the coldest days and cool on the hottest. The system is efficient and I'm spending less and getting more!

We had Coster Heating and Air install a Heat pump two returns and swap out an air handler for our upstairs. They also installed a Dankin Mini split for our sun room that we are really enjoying. On the front end, Brian was great to work with. He took time to make sure that we were getting exactly what we needed, kept us within our budget, and never tried to over sell. Daniel and Scott did a great job on the install and made sure that they covering everything that we needed done. We highly recommend Coster Heating and Air!

The Coster team was incredibly professional in every aspect of HVAC replacement. While they initially replaced one of my HVAC units that could not be repaired, they did such a good job that I contracted with them to replace the other two units. Costs were as agreed upon, team was polite, team covered their shoes, and overall a great experience.

Very good company to do business with. They had to come out a few times after the new installation but it's working great and the system is very nice. It's the quietest unit I've ever heard run.

Coster replaced one of our AC units and repaired the other. Both have been functioning properly and efficiently for several months now. They were able to get us on the schedule in a reasonable period of time and the service technician was knowledgeable and friendly.

They have saved us money. The people we used before could never fix our problem. It didn’t take Coster Heating 10 minutes to find it and fix it. They are very nice and easy to work with. Very happy with them.Services: HVAC system repair, HVAC system maintenance

As a General Contractor, I researched a relationship that I wished to align for my primary build here in the area. Coster's reputation and dedication to their clients is quite impressive. Each and every employee, including the owner, have consistently been remarkable in their knowledge, and level of excellent service. The owner specked out my build design and has stood by the systems in place for a roughly 5K SF build, with very challenging ceiling peaks over 25'. Cannot say enough positive things about Coster Heating & Air.

I only trust Coster to take care of my HVAC system. They really make the customer feel special. I can always depend on them to come out to my house in a timely manner, and fix the problem correctly and in a timely manner. This system was installed by Coster year's ago, and is still working very well!Services: HVAC system repair, HVAC system maintenance, A/C system maintenance, Heating system repair, A/C system repair, Installation

We have been using Coster H & A for more than 10 years and have always been very please with the service and time. They have installed 2 systems in other homes. Plus they service the home we now live in even though they did not install it. I wouldn't consider anyone else. Thank you for being there when needed.

Really impressed by Coster's service. I called them out for what I thought was a major issue and they were able to fit me in the schedule quickly. They took the time to find the root of the problem and surprisingly it was an easy fix for them. Our previous HVAC company had wired something incorrectly and it went unnoticed for a long time. Now everything works perfectly and we are very comfortable. Can't thank Coster enough for their professionalism and quality work. We'll be using them again in the future!Service: A/C system repair

I'm a handyman, but don't do HVAC. I called 1 other local company who wanted to charge me overtime for labor AND materials! COSTER gave me a price, came when they said they would, did a proper repair, and charged me what I was quoted. Plus, way cheaper than the first clown I talked to.Services: HVAC system repair, A/C system repair, Repair HVAC

Coster Heating & Air Conditioning installed an American Standard heat pump system in my new house. I couldn't ask for a more professional company to perform the work. From the equipment selection to the actual install, everything went very smoothly. The office staff and the installation crew were a joy to work with. We highly recommend them to all, you won't be disappointed. After two full years we are still very happy.Services: HVAC system maintenance, Installation, HVAC duct & vent installation, Heating system maintenance

Awesome service & technicians. I had a couple of trane mini split unit problems that weren't diagnosed correctly by other HVAC companies. I called Coster & they diagnosed & corrected the issues. I will always use their company because they are the best.

Always prompt with a call back to see what your needs are, they have always came out and repaired our problems. When our system goes out we will definitely use this company to install and service the new unit. True story we had a another company come out to us and they stated we needed a whole new system, yes ours is old but we knew it wasn't that bad, the owner stopped by on his way home walked in and seen the problem in less than a minute. The problem was animals (rodents) had gotten into the duct work and the insulation wrap stopped the vents up.Services: Heating system repair, A/C system repair, Repair HVAC

When the air conditioning unit in our fellowship hall went out they were able to find us a new unit when there were very few available and at a reasonable price. As soon as the unit was delivered they were there replacing it and in a professional way. We are very satisfied with the unit and their workmanship and would recommend Coster to anyone that needs a/c work done.Claudie MarcengillBethel Baptist ChurchServices: Heating system installation, Install thermostat, Install AC

Totally impressed. Our whole AC system needed to be replaced during the hottest time during the summer. Coster kept our old unit going until they were able to replace our entire system. We are very thankful for their effort to keep us cool and their amazing quality of work performed. We HIGHLY recommend them to everyone !!!!!!!!!!Service: Installation
