Description of Work: OUR FURNACE KEPT TURNING OFF AND NOT HEATING PROPERLY. DELJO CAME IN THE SAME DAY THAT WE CALLED. HE INSPECTED THE FURNACE, REPLACED A PART AND TURNED UP THE GAS PRESSURE WHICH WAS SET TOO LOW. NO PROBLEMS SINCE THEN, AND THE HEATER NOW WORKS MORE EFFICIENTLY.

BOB TURK WAS WONDERFUL AND VERY PROFESSIONAL. HE CAME OUT TO THE HOUSE AND PROVIDED A FAIR ESTIMATE ON THE WORK THAT NEEDED TO BE DONE. SINCE I WASN'T PREPARED FOR THE AMOUNT OF WORK NEEDED (WE RECENTLY MOVED INTO A NEW HOUSE), WE HAD NOT YET BUDGETED THE AMOUNT OF MONEY REQUIRED. BOB WORKED HARD TO FIND A WORKABLE SOLUTION THAT WE COULD AFFORD. WE ARE PLANNING TO USE THEM IN THE SPRING TO COMPLETE THE REMAINDER OF THE WORK.

BOB TURK SUGGESTED AN INNOVATIVE, COST EFFECTIVE SOLUTION THAT WORKED WITHIN OUR BUDGET AND WAS EXTREMELY PROFESSIONAL TO DEAL WITH--ONE OF THE BEST SERVICE PEOPLE I'VE RUN ACROSS. UNLIKE OTHER ESTIMATORS, HE DIDN'T TRY AND SELL US A LARGER SYSTEM THAN WE NEEDED. WE WILL DEFINITELY USE DELJO AGAIN.

WHAT A PHENOMENAL COMPANY. I WAS IMPRESSED FROM THE MOMENT BOB TURK CAME OUT FOR AN ESTIMATE. HE WAS SO THOROUGH, INTELLIGENT AND OPEN TO QUESTIONS. EVEN THOUGH THEIR ESTIMATE WAS HIGHER THAN THE OTHERS WE RECEIVED, I FELT INFINITELY MORE COMFORTABLE GOING WITH DELJO. THIS WAS A TOUGH, TOUGH JOB, GIVEN THAT OUR HOUSE HAD NO DUCTWORK AND VERY SUBSTANTIAL FLOORS TO DRILL THROUGH -- 8 INCHES OF CONCRETE IN SOME PLACES! I DIDN'T WANT TO RISK IT WITH ANYONE ELSE. AND I LOVED THE GUYS WHO DID THE WORK, DAVID AND MARK. NO MATTER WHAT OBSTACLE THEY CAME UP AGAINST, THEY FOUND A WAY TO AIR CONDITION EVERY LAST ROOM OF OUR HOUSE. BOTH GUYS WERE FRIENDLY AND JUST TOTALLY SKILLED AT WHAT THEY DO. SERIOUSLY, I CAN'T SAY ENOUGH ABOUT DELJO. THEY'RE WORTH EVERY PENNY.

VERY KNOWLEDGE, VERY FAIR PRICE AND EXTREMELY QUICK SERVICE (CAME THE DAY AFTER I CALLED AND WITHIN A 15 MINUTES TIME WINDOW FROM THE TIME MY APPOINTMENT WAS. APPT: 3:00, CAME 3:15). VERY HONEST ABOUT WHAT I NEED FOR MAINTENANCE (WHICH IS NOTHING, TOLD ME MY EQUIPMENT IS IN GREAT CONDITION. INCLUDING A/C WHICH DOES NOT NEED TO HAVE FREON REFILL ALL THE TIME, VERY HONEST). EXCELLENT COMPANY, EXCELLENT SERVICE, GREAT PRICING (I HAVE DONE MY HOMEWORK ON CHECKING PRICES AROUND). HIGHLY RECOMMENDED. AAA+++
Description of Work: MY FURNACE STOPPED WORKING AND AFTER DOING SOME RESEARCH, I THOUGHT IT WAS THE CIRCUIT BOARD. THEY CAME OUT, TOOK A LOOK, DETERMINED VERY QUICKLY IT WAS THE FLAME SENSOR. REPLACE UNIT, ALSO DID A THOROUGH INSPECTION OF MY FURNACE.

THIS IS A GREAT COMPANY WITH AN EMPHASIS ON GOOD CUSTOMER SERVICE. THE REPRESENTATIVE CAME TO MY HOUSE THREE TIMES: ONCE TO ASSESS MY NEEDS AND PROVIDE AN ESTIMATE, ONCE ON THE DAY THAT THE EQUIPMENT WAS INSTALLED, AND A THIRD TIME TO EXPLAIN THE SYSTEM TO ME AND ANSWER ANY QUESTIONS. HE EVEN TOOK THE TIME TO EXPLAIN HOW TO USE THE SYSTEM MOST EFFICIENTLY. ALTHOUGH I HAVEN''T HAD THE AIR CONDITIONER THROUGH AN ENTIRE SUMMER YET, SO FAR IT SEEMS GREAT. I WOULD USE DELJO AGAIN IN A MINUTE!
