My system is now working great. In fact, it's running better than it has in years and easily cooling down the house instead of struggling to reach an ideal temperature.

Further communication was excellent every step of the way to let me know when he would arrive (we had some severe weather that caused a delay).

After receiving two extremely high estimates and a long wait time from a couple of regional HVAC…read morecompanies for a part repair on our broken 6-year-old A/C unit, I was referred to Landgarten Heating & Air Conditioning by a friend. My initial call was returned the same day, and an appointment was scheduled for the evaluation the very next day. Dave was straightforward and honest about the repair of an obsolete machine with a leak vs. replacing the entire inside and outside unit; the pricing for the replacement was not much more than the original part repair estimates, and came with a longer warrantee. Along with the savings, Landgarten HVAC was able to work quickly and have the units installed the next business day; I cannot stress how important this timeliness was during a heatwave, while working from home with an active toddler in a 95F home. Dave and his assistants were friendly, professional, knowledgeable and performed a quality install with a quick turnaround. It has been a few weeks and we have not yet had any issues. I would definitely refer Landgarten Heating & Air Conditioning to anyone looking to repair or replace their HVAC systems.

When I spoke with Tom he was the definition of professional, knowledgeable, prompt, and transparent with his pricing. He came by later that same day to evaluate the job and provided a quote within 24 hours which came in substantially less than his competitors for the exact same work/materials. Initially I had some reservations about moving forward with Comfort Air because they had no online reviews but Tom readily provided three references who only had great things to say about their experience with him. And boy am I glad I went with Tom. He owns the company and does all the work himself ensuring its quality. He replaced the whole system with a new Unico system (and even helped fix a couple of my old ducts that needed some TLC) over the course of a morning. He and his team came prepared, worked efficiently, and left the space spotless when they were done. Comfort Air/Tom delivers excellent service for a competitive price and is the great type of business that seems so hard to come by these days. I truly could not have hoped for more!

In all honesty, the prices were not super far off - the recommendations, or lack of were the biggest variable between all of our proposals. This is kind of long, but like others have mentioned, the experience was so good that I wanted to make sure to take the time to give this feedback. 1. Borden was the only one who recommended a chimney liner in our new system. Which is important in the newer 84% because the temps are not as high as they used to be. But even more important in the 90% model where the water heater would be an orphaned appliance. Which is actually a pretty serious safety concern. 2. Borden was also the only one who recommended a new expansion tank and offered to cut back to the steel one if we wanted to shave a little off of the price. A number of places i looked said that the amount of new installs they see using an older tank is mind boggling. And there are numerous benefits to the new style including eliminating air, rather than just controlling it. 3. Borden was the only one to add more options ala carte, especially the outdoor reset option. I really appreciate the flexibility your proposal offers. 4. Borden was the only one who actually opened the boiler to make sure they saw it was leaking etc. Everyone else heard "new boiler", saw dollar signs and that was about it. 5. Borden was also the only owner to come out! Which i think is extra important when it's one of these big jobs where you are not only trying to get the customer set up with a good system, but start a relationship for service and maintainability in the future. Mission Accomplished. Finally, they took tons of time with me explaining how each component would be installed, and a very thoughtful and insightful explanation into why you recommend those pieces. Not at all in a pushy sales way. I'm really excited about our new system and it just so happens today is the coldest day of the year and we have invaluable peace of mind! It also looks like a work of art - the company absolutely takes pride in their craft and it shows.

My wife and I bought a house in Havertown, PA while living in California. My local parents…read moreinformed me that the A/C was not working. My wife and I engaged with Borden as the unit is a Bosch and not all A/C companies service the brand. My wife gave the receptionist her credit card number and asked her to fix any issues and/or perform routine maintenance. She made this request because we did not trust my parents that the A/C was not working (user error more likely). We did not hear from Borden on the day of scheduled service. The next day my wife told me her credit card was billed $1200. Via text or email, the technician explained that my parents were using the wrong thermostat. The technician proceeded to place a float safety at the secondary drain pan and also recommended adding another return to the unit. He charged 300 dollars an hour for labor. His half hour drive was also billed at 300 dollars an hour. Let me be very clear. There was nothing wrong with the unit. My parents did not see a second thermostat. The technician then did 1200 dollars of work without consulting us. A float switch installation should not take 2 and a half hours by an expert. Three hundred dollars an hour is an expert wage. To top it off, a week or so later, our painter informed us the A/C was not working. My wife found a different company. That technician found that the float safety valve turned the unit off. The drain pan was full (good job Borden). When he purged the drain line, he found expected sludge and also PVC shavings and glue. So... Borden did a good job installing a float valve, but the shoddy workmanship contributed to a blockage. The new company charged $150 to clear the line. If I could give Borden zero stars, I would. I don't begrudge anyone trying to making a buck, but I certainly will never do business with them again.
