Smoke alarm issue

Pleased with how quickly you came....and my dog is very happy he isn't hearing that noise any more! Service was professional and thorough. Mike checked the other detectors as well and took out the locking pin so that I can change the batteries myself if need be.

Excellent Service

Black-Haak installed my furnace and AC when I built my house. I've had them maintain and service my system ever since and have always been very pleased with their expert knowledge and quality of service. Their pricing is very fair and they are very honest up-front about the cost of things. I know I can rely on them and will be a lifetime customer! The technicians are VERY friendly and helpful, they are great to work with!

System problem. Customer stated that the furnace was short cycling. System would turn on for a min then cycle off. It repeats this over and over. This has been happening for the last few weeks. I checked filter. Filter was a bit dirty, but ok. Cleared drain line and checked drain trap. Cleared pressure switch tubing. No obstructions found. Cycled system and unit failed after a min with a pressure switch code. Removed intake venting pipe and cycled again. System ran for over 15 mins. Recommend furnace clean and tune. Recommend leaving venting off until cleaning. System operating at this time. Job complete.

Need install crew to return to rerun air intake at furnace. Currently above burners and gas valve. Move it to side of furnace. Upon arrival the furnace would not light. Found that the gas valve was bad due to water damage. Had the office run out the new gas valve and replaced it under a warranty. Performed a preferred customer furnace cleaning. Cleaned the unit. Cycled the furnace. Checked the gas valve and performed a furnace combustion test. The furnace is running normally at this time.

Looked at fans that were loose. Found both fans had loose screws. Put washers on the screw heads so they wouldn’t pull through the bracket slots and tightened the screws for both fans.
