HVAC reviews in Sterling, Virginia

I have a few properties and these guys are the best HVAC i've ever worked with.

Reasonable pricing. Really knowledgeable.

Responsive service. Fall check-up and tune-up time. Careful and detailed work. Todd is great! Recommended by a friend 2-3 years ago. Use them each spring and fall. Could not be better.

Cardinal Heating & Cooling has been providing their excellent service to us for over three years! John, our technician is always punctual and does the job well.

A friend suggested this company to us after our A/C malfunctioned recently. Thank you Cardinal Heating and Cooling for squeezing us in! The Scheduler was personable and empathetic. The Techs were professional, responsive to questions, and moved with purpose.

Only company I will ever use! Tod is knowledgeable, thorough, and patient...answered all of my questions and explained everything in detail. quick response, arrived on time, and didn't rush through the process.affordable and worth every penny. so nice to know I have someone to call that I can trust! Highly recommend!!!

I am perplexed by a scheduled visit I arranged with this company. I took off work to spend at least an hour with this company. The two men promised to email a proposal for the required work within the following 24 hours of the visit. It has been months now and I have not heard one word from them. One may ask, why not call them?, well that want happen. I will not run after companies who do not follow through on commitments. That is a red flag for me. Beware!

We have been customers of Cardinal for over 25+ years and have never been disappointed! As usual John was right on time and very efficient in performing our bi-annual maintenance. The legacy of Nelson and Todd lives on!

For the past twenty years, Cardinal has provided us with superior, expert, prompt, and friendly service. Everyone at Cardinal is always patient, understanding, and polite. In sum: Consistently great work, quality products, and fair prices.

I had my hvac system inspected for spring by another company and was told I was low on Freon. I was put in contact with Cardinal Heating & cooling from Trane's website and so I inquired about getting a diagnostic to confirm there was a leak and to identify where it was for $109 and I also wanted a quote for a new system in case I had to replace it. The owner Tod came out to the site and his associate hooked the meters to my A.C. unit and just said pressure and temperature readings point towards low Freon and that if I wanted a leak test it would be another $300+ to do it. He also said he didn't have any Freon to sell and that it was illegal to sell which is not entirely true. The ban is on importing or manufacturing new Freon but it is perfectly legal to recapture used Freon, clean it and sell the recycled Freon. Also he told me that if I wanted to flush out Freon use an alternative to Freon I would have to install additional equipment to existing system which is also not true. I finally received a proposal from this company which was at least twice the price of the next highest bidder (no specifics just a number). To be honest if they didn’t want my business in the first place they should have never offered to do the diagnostic. Would have saved me $109 and an hour where I could have had someone else more honest trustworthy to come. This is one company to avoid!

Cardinal Heating and Air are outstanding! Appointments are on time, system checks are thorough and detailed. The technician was friendly and knowledgeable.

Jake Wayne, the plumbing technician was awesome! He was very friendly, quick and knowledgeable. Thanks again Cardinal!

Excellent service from start to finish. It was very easy to schedule my appointment through email. The technician was on time, efficient and answered all of my questions. I'll definitely be calling them again for my next service appointment in the spring. I'd recommend this company, no problem.

I had to replace my thermostat that came with the Trane HVAC system I had installed at our house a few years ago. I soon found out that the original installer(A differnet HVAC company) had registered the wrong model of thermostat - Comfort Link 900 instead of Comfortlink 950 that was sold and installed with the system. In fact, they failed to register the thermostat all together in the original extended warranty and I had to call Trane to have it corrected and to allow the replacement of the unit to be covered in the extended warranty contract I purchased from Trane.

The Trane customer service person I talked with was amongst the worst I've ever experienced (on par with Comcast for reference). Slow to understand, hostile and impolite, and worst of all inept. Even though it clearly was not my fault, she insisted I had to find the original installer who by now is out of that business and untraceable, and have him provide the installation documentation to Trane.

I called Kristen from Cardinal, who immediately understood the issue and agreed to communicate with regional distributor Lyon Conklin on my behalf. Kristen had worked with them tirelessly for several days to no avail, keeping me updated by phone, until she involved the distributor's manager who together with her realized the absurdity of the situation and decided to provide a replacement unit for me and work the paper trail in the background ending my suffering the consequence of a warranted malfunctioning $9,000 HVAC system I bought and paid for from Trane merely 3 years ago.

My purpose in writing this detailed review is to highlight a few important suggestions to anyone considering an HVAC system from Trane:

1. Think twice before buying from Trane - many reviewers have had similar experience dealing with their CS. They may have some good products but they don't stand behind them in a reasonable manner, and run a horrific customer service.

2. As Kristen perfectly demonstrated it is just as important to get a reliable dealer for your HVAC needs as it is to find a good brand.

3. There are still a few very dedicated and well intentioned customer service professionals such as Kristen and the Lyon Conklin executive who truly live up to their function. Kristen worked above and beyond my expectations, even though she had no obligation to do it for me, and the executive at Lyon Conklin understood I shouldn't be punished for a bureaucratic error for no fault of mine.

I've since met with Cardinal's owner Tod, who came to sercice my system and it is clear he had integrated this customer service attitude into his business.

I highly recommend hiring them for any HVAC need you may have in the future: I know I certainly will.

Tod was very professional and was able to fix my issue in under 10 minutes. I was able to get a tech coming to my house in less then 24 hours when it was very hot outside. When I emailed to schedule an appointment, even though they were very busy, they were able to give me a window so I could go about my day. Can’t be happier.

Kristen from the customer service team was extremely friendly and scheduled us quickly with an accurate over the phone quote. She patiently answered all of my questions as well. Greg arrived on time answered all of our questions and efficiently installed our new TRANE thermostats. He was very thorough and walked me through a tutorial of the thermostats to ensure I understood everything including the online registration. Overall a great experience and would definitely call them again!

Technician did a great job, he arrived within the appointment window, quickly diagnosed the problem, explained everything he needed to do, and made the necessary repairs. The entire process took about an hour and my A/C is back up and running again! Highly recommend this company.

We have used Cardinal for years now at 2 different properties. They perform our annual HVAC maintenance, have installed numerous systems for us - water heaters, humidifiers, furnace, and AC units. Service, prices, and products installed have all been top notch.

We have relied upon Cardinal Heating and Plumbing for at least 22 years. It is outstanding for quality of service, promptness, integrity, and price. It's a family firm where we know who we are talking to. These are all qualities that are hard to find these days!

We have been Cardinal Heating & Cooling's customer for over 10 years since they replaced the upstairs system (furnace/ac). Tod (the owner) is very professional, very knowledgeable and never pushy. Our 20 year old furnace (downstairs system) was acting up so we requested some quotes. Tod was extremely helpful and prompt in answering all our questions.

We made our decision and Tod himself installed the new furnace and ac with his assistant's help. The system was installed and it's working like a charm. Everything from the old system was removed and the basement is spotless. We could not be any happier with the service and the products installed.

We are very glad we chose them 10 years ago and this year to replace our ac/furnace systems and will definitely continue to be their client in the future.

I am very pleased with the service that I receive from my technician at Cardinal Heating and Cooling. John Rivas shows up on time or even a little early and is professional, efficient and courteous. Thank you Cardinal for helping to keep our furnace in top performance.

Super experience with Cardinal HVAC. The team is wonderful from the office all the way down to the lowest technician. They are prompt, courteous, knowledgeable and are willing to solve your problem in a professional manner. I had my system installed in September of 2017 and we have been warm in the Winter and cool in the Summer ever since. Count on Cardinal. You can go wrong. Ask for Tod
