The Constellation Advantage

Home » Constellation Advantage

Hundreds of times a day we answer the call to keep the hot water flowing and make a home more comfortable – warmer in winter, cooler in summer. Every time we enter a home, we leave it a better place.

We’re committed to making every customer experience a pleasant and convenient one. When you use Constellation for your repair, efficiency tune-up or installation, you can look forward to our team of professionals providing incomparable personal service and 100% customer satisfaction. Our team has been providing heating, air conditioning and plumbing services in Maryland for over 20 years. We’ve achieved a satisfaction rating of over 95% and 9 out of 10 of our customers would refer us to their family and friends. We’re excited to bring that level of customer service to your home.

Here are some of the reasons why we’re the best choice for heating, air conditioning and plumbing services in your area:

Training & Professional Excellence

The technicians at Constellation adhere to the industry’s highest standards of professionalism and knowledge. Our technicians are licensed professionals, meaning they have demonstrated their knowledge of today’s sophisticated heating and cooling equipment. Our technicians exceed local codes and safety requirements, are fully vetted and pass a thorough background check. You can be sure the technician that shows up at your home will get the job done safely and efficiently.

We know not all emergencies happen between 9am and 5pm, so we provide 24/7 emergency service. We’ll be there for you when your furnace stops working late at night, or your air conditioning won’t come on early in the morning. Plus, we’re never far away. Our technicians live in the communities they serve, so we can get to you fast and restore comfort to your home quickly. We’ll always show up on time, in uniform and ready to make the repair.

Customer for Life

We believe that we offer the very best customer service – that’s why we created our Customer for Life program. When you purchase a new heating and air conditioning system from Constellation, you’ll enjoy benefits that no other company can provide:

  • Low Price Assurance: If you receive a written proposal from a contractor with equal product and installation specifications within 10 days of receiving our proposal, we will complete the work and credit you the difference, plus $100.
  • Replacement Guarantee: With uninterrupted coverage under the Extended Labor Program (ELP), if your air conditioner or heat pump compressor or furnace heat exchanger fails within five years of the date of installation, we will replace the air conditioner, heat pump or furnace at no charge.
  • Money Back Guarantee: If your new equipment is not working to the manufacturer’s specifications within the first year after installation, we will make any necessary adjustments or provide a refund on returned equipment.

Home Service Plans

With a Constellation service plan, you have coverage on the most essential equipment in your home. When your heating and air conditioning system or water heater break down, you pay nothing for covered parts and labor. You’ll have peace-of-mind knowing that a trained, certified and licensed technician will provide priority service and quickly make the required repair.

Protect your household budget from unexpected repair costs with a service plan from Constellation. Plus, unlike other plans, there’s no deductible to pay when something breaks down. We have you totally covered. And when it’s time to upgrade to a new heating and cooling system or water heater, service plan members receive additional discounts and notification of exclusive offers.
