You are right I am not a expert in heating and cooling that is not my profession. I hired another company turns out there was a leak in the fiberglass tape that caused the issue. Ron's heating blamed the builders saying not enough insulation or etc. Well you're wrong. You guys come to my house for 10 minutes . Yes it's on camera you can say different but it shows when you stepped in the doors and drove off. Total 12 minutes. You guys want to charge me a diagnostic fee FOR WHAT? You guys didn't diagnostic the issue another company did within 30 minutes. Get a second opinion before hiring this company because they are a one sided company and that side only Benefits them. I have my newborn room with improper heat coming into the room. It's 61 degrees when the house is set to 70 degrees and they blame the builders when it was due to their issue that they didn't even diagnose another company did. JOKE of a company. I tried paying the diagnostic fee that I honestly shouldn't because they rushed and didn't even spend the time to figure out the cause. They wanted to charge me a 3% fee for a debit card. Then they tried to charging me for a visit the the prior owner did and never collected on me. The owner wife was trying to pull a fast one on me then said ohh sorry I didn't realize it was a different name. Luckily I asked my total before providing my debit card number

Also checked my capacitor and suggested I replaced it due to it not running at full compacity which I did(obvious up charge). They gave me quotes for a few different options to do like replacing whole unit, cleaning ducts, replacing fan etc. I said I'll have to talk it over. Called a couple weeks later to find out the price again. They wanted to charge me another service fee so they could come out again to tell me the quotes from prior visit. On top of another service fee for the service when they do the replacing of part. So up to 3-4 service fees for one issue that they did not resolve. At $100 dollars a pop not including anything else.

This is my first review, EVER: (Once upon a time we had the Yellow Pages to help us find reputable…read moreservices....Uncle Ted provided reviews!) DeKalb Mechanical has serviced my furnace 3 times in the 6 years since I've owned my home, and this week assisted in a chimney replacement. I chose DeKalb Mechanical because the brand new furnace had been installed by them before my purchase. Andy & Charles have always listened patiently to my frantic description of the problem and sent repair technicians within the day. The techs are consistently courteous and knowledgeable and pretty good about cleaning up after themselves.. The final charge always seems high to me - they're probably competitive - I'm "old", living on a fixed income, and think any service costing more than $200 is too much! I've been particularly crabby these last two weeks when I finally established that my various furnace issues have most likely been related to a roof leak adjacent to the chimney. (Had the roof repaired in 2019!) The first estimate blamed the flashing, and bid $2000 for the flashing and a plywood/shingles replacement. A second estimate with a different roofer found NO issues with the flashing but said there was no cap - estimated charges $400. (I liked the 2nd bid better, but even I could see the flashing was rusted out.) Finally, the first contractor proposed replacing the brick chimney & flashing with a B-vent, requiring the coordinated assistance of my HVAC people - the best estimate was 2 grand for the roofer and not more than $1000 for the furnace folks. My final charges:$2850. I was fuming when I completed the review - assigning only 2 stars. (I've spent thousands of $ on roof repair and furnace servicing and the leak was probably present before I bought the home!) But that is NOT THEIR FAULT!! Before the ink could dry on my review Nathan, DeK Mech's man that oversaw the project, was at my door to find out what he (they) did wrong! Nothing. They did nothing wrong. They did it ALL RIGHT. Arrived an hour before originally scheduled, performed their work efficently and worked as a team with the roofers. I'll be calling DeKalb Mechanical this fall before I start the furnace for the season. Keeping my fingers crossed!
