Goodco/Haller is a great company with courteous, polite, friendly service people. Ron checked everything and gave me a heads up on a not-yet-a-problem but-could-soon-be-a-big-problem. Whenever I need repairs or maintenance, I know who to call.

Haller sent a very professional and efficient team to do our AC/Furnace installation. They removed and installed the units in 6 1/2 hours with minimal disruption and left their work area cleaner than when they came in!

Haller has updated some of their communications. I received confirmation of my online booking. A text with picture of who was coming. Another text to state employee was on the way. If you are looking out for safety, I can't recommend a better company. I have been using Haller services for about 10 years. Haller has been great about everything. I know some of you are going to say expensive. I have never needed a second visit for anything that they fixed. Done once and done right. Thank you!

Always prompt service with friendly and professional technicians. Did full maintenence on my hvac system and corrected a leak for no cost. May not always be the cheapest, but guaranteed to be early or on time, available when you need it, and expertise you cannot diminish

Great job, on time and very professional!

On time, respectable, did not waste my time or his. Would recommend.

Kurtis knows what he's doing! He did a great job repairing our heating system.

Excellent electrical service! The electrician arrived promptly, diagnosed the issue quickly, and completed the work in under an hour. The quality of the work was outstanding, and everything was explained clearly throughout the process. Best of all, the price was very affordable with no surprise charges. Professional, efficient, and reliable service from start to finish. I highly recommend them to anyone needing electrical work done and will definitely use them again in the future!

Darius was fantastic!

Today we had routine service on our heat pump system and hot water heater. Notice of and arrival exactly as scheduled. Communication of system performance was outstanding and the explanation of some necessary replacement parts was commendable. Five star review is well deserved.

Noah arrived promptly as scheduled and did an excellent job. He conducted scheduled maintenance as per contract and also fixed an issue I was having on my Bryant heat pump involving a communications error. He explained everything thoroughly and professionally. I give both Noah and Haller Enterprises a 5 Star review!

Great service from Haller for fixing our electrical problem. Joshua was prompt and had the problem fixed in no time. We use Haller our heating air conditioning and plumbing service as well. Always great service.

Jared aways does a great job in serving are furnace 👍

Well maintaine

Our church in Downingtown recently constructed a memorial garden. This was a fairly diverse project that required masonry, landscaping, and electrical crafts. We selected Hallar for the electrical portion of the project which required them to work closely with the mason in order to ensure a coordinated installation. Things went very well and the end result was a very successful project. Hallar installed the lights and a timer system which make for a very subdued and quiet setting in the evenings. In addition, during excavation for the masonry walls, our water service pipe was damaged. Because Hallar’s is a multi-craft company they were able to make the necessary repairs to the water line without any disruption to the project schedule at a very reasonable price. We would recommend Hallar’s for any project which requires electrical, plumbing, or HVAC expertise. They are proven to be cooperative, timely and highly skilled.

Robert did a great job. Our furnace is still working.

My experience with Ricardo on Friday was very good. He did a great job explaining everything. I am so glad I went with Haller!

Great job

Our HVAC has been needing replaced for several years but we kept putting it off. Finally our ac went when they were calling for a very hot couple of days. Called for estimate and got an estimate next day and installation for furnace and AC happened the very next day!!! Salesman and installers were fantastic to work with. Great job by all.
