Service & Repair

Our service department is able to handle all levels of home service calls from upgrading your thermostat to replacing compressors or coils. We service ALL brands and types of heating and A/C equipment. Our technicians will diagnose your system and inform you of any needed repairs or options for your system.


HVAC replacement may become a necessity because of failure of your old system, the desire to become more energy efficient or for overall home comfort and satisfaction. Our qualified service technicians can check your system and advise you on the pros and cons of repairing or replacing your existing system based on our findings.


In addition to providing quick and reliable HVAC repair, our technicians can also provide yearly maintenance on your home heating and cooling system. Maintenance is key to maximizing your system’s efficient operation. Having your Home Comfort System professionally maintained gives you the following benefits:

Message from David & Michael:


First, we want to thank you for visiting our site. We realize this isn’t Amazon or YouTube, so there can only be a handful of reasons you are seeking us out. Here are a few guesses: Your heating and cooling system is broken. You’re looking for a second opinion. You’re wondering if we are cheaper. You heard we are a very good company. Do we have an annual maintenance program? You’re checking to see if you can get a feel for us from our website. And lastly, you’re a homeowner that wants to know who you are letting into your home and what their intentions are. We are going to answer these questions and a few more.

We are a North and South Carolina licensed mechanical contractor. We are bonded, insured and pay all the taxes, workman’s compensation and inspection fees associated with running a city and state compliant HVAC company. If you are having problems with your Charlotte Air Conditioning our technicians are real technicians. They get dirty and find the “Real Cause” of the problem, not some excuse to pad their pockets. The last thing we want our technicians to say is “you need to replace it”. NASCAIR understands this economy. We are living through it with you. There will come a time when you can afford to replace the system and we hope you will remember our integrity. Our A/C MAINTENANCE program covers the entire system – condenser, coils, drains, ductwork, system charge and system electrics. Our credentials are – A+ with BBB, A+ on Angie’s-List, Members of the North and South Carolina State Board, David being an alumni of the WBT Home Improvement Show, our testimonials and, of course, Yelp and Google reviews.

Now the last two items go hand in hand. Our technicians are well paid. We don’t want them leaving and going to the competition. They are smart, courteous and reflect our moral compass. If you know anything about running a successful business you know it’s the employees that are the lynchpin to satisfaction, so we want them happy and excited to come to work hence we charge a fair price for services rendered. We don’t want to be the cheapest, we want to be known as craftsman – knowledgeable and sought out for our expertise. We have worked hard and learned many lessons in order to be considered amongst the best in our industry. So, if you are basing your decision on cheapest price or want to marginalize the product you would be missing the tangible value and experience that David, Michael and every NASCAIR employee brings into the solution.

Sincere Thanks
David Drew and Michael Thiessen

What Our Customers Say . . .

I would like to take this opportunity to tell you how happy Cindy and I are with the system and the thoroughness and professionalism of your team.  It has been a pleasure doing business with NASCAIR.

These guys are the best. For several years and through a variety of both big and small heating and cooling issues, Nascair has consistently provided us with fast response, technical expertise, fair pricing, and an excellent work ethic. They always show up when scheduled, even giving me a 5-minute warning call so I know precisely when they will arrive.  Nascair is big enough to provide rapid reaction time and a deep knowledge base, while still of a size to provide the personal touch. Above all, I appreciate the integrity displayed by everyone–owners and technicians–and how they always put my comfort and safety above all, going the extra mile to be sure that even the work of others before them has been done right. Nascair offers what we homeowners really want: excellent service that we do not need to question or second guess.  After 25 years of homeownership in Charlotte, I am thrilled to have found Nascair.
