Get matched with top central a/c installers in Colmar, PA

"Andrew replaced our heating and cooling system and went above and beyond. He ran into a lot of faulty wiring from the previous installation and made everything right so we have a safe and functioning unit. He worked long hours to get the job done quickly as well. Thank you Andrew! Totally recommend and will continue to use him and his company."

"We had a central air conditioning installed in our 55 year old home (replaced 3 Sanyo zone cooling units.) It was installed in our attic with ducts in the closets to the first floor. From the first phone call, to the salesman coming to our home, installation, inspection, and a service call, everything was wonderful! Very professional, knowledgeable and courtesy. So grateful to Home Advisor for matching us with All Seasons. Keep up the great work!"

"The employees were all informative, answered all my questions and were able to install a new A/C unit the next day. They were on time for both the check and the install. They were respectful and completed the install earlier than expected. I would highly recommend Rohrerâ s!"

"Sales rep measured rooms and windows to perform a load cal'n. Proposed a quality Carrier system at a reasonable price. The installation took a little longer than expected due to use of an inexperienced helper, but eventually it appeared to be a quality installation. They met my requests for minor modifications/enhancements to allow easier maintenance. Workers wore masks at all times, used drop cloths along walking paths and shoe covers, so the job was kept clean. Took time to explain system, installation and maintenance points. Were honest about risk of condensate pipe freeze-up and potential remedies, and "orphaned" water heater. Overall, quite satisfied with the equipment and installation. Awaiting finalization of punch list paperwork items."

"Very professional installation. Was done in a timely fashion and the crew was very professional and clean. Huge difference in the comfort of our home now."

"Horizon did a great job on our shower faucet install."

"We have a yearly maintenance agreement with them after they installed our air conditioner. They're very efficient. They come when they say they're going to come and do their work. The last time they were here for AC, they did find a problem and fixed it at no charge."

"The Job Went Good From Doug In The Office To The Men In The Field That Did The Install. Thank You"
