Description of Work: Re-installed radiators and replaced leaking valves- it just seemed pricey- and we had a problem they were unwilling to fix- felt we needed a new boiler- a friend in the business and my husband actually repaired the boiler - having said that I still thought their work was excellent- they also fixed a gas leak- which was awesome.

Excellent service. The service attendants have always been punctual, professional and communicative.
Description of Work: Purchased a 3-year maintenance agreement for $479.00 for our furnace, air conditioner, water heater and humidifier. Guardian calls us each spring and each fall to schedule maintenance and cleaning; we have 24-hour emergency service and priority treatment in scheduling service calls. Repair parts are charged at a 15% discount to list and repair workmanship guaranteed for 30 days from date of repair. We purchased a Honeywell thermostat on April 17, 2007 for $236.30 during a maintenance visit.

They gave me a 4 hour window in which they would come and were right on time. They called right before they came as I asked them to since I have 2 dogs that I did not want to bark at him. They were polite and professional. I would use them again.
Description of Work: They came out to perform annual check-up and maintenance on our 2 A/C units. They also added some freon since we needed some.

I couldn't figure out what the problem was, so I was glad they were able to figure it out. They have worked on my heating unit before and they did a good job this time too. I really like the way that they get to the house the same day most of the time.
Description of Work: They reconnected a heating vent that had been knocked loose by some critter in the attic.

We did wait 1.5 days for a repairman to show as the weather has been really, really hot(we are an existing client with several buildings). Our repairman questioned my need to know what comprised the $495 charge. I wished to understand what portion was hardware, labor, etc...and I wanted to be certain that he was also addressing the root cause of the circuit board going bad that he has claimed was water damage. He was unbelievably rude, told me that if I had questions, there were plenty of people who did not and he would gladly leave and go to the "hundreds" of other calls that were on his book for the day! He essentially held me hostage like those horror stories you hear about.
Description of Work: Service call to fix a non-working air conditioning unit located in an apartment. Upon inspection of unit found it non-operational. A "bad circuit board" was replaced. Repair man cited "water damage" as cause but would not investigate root source, so I replaced board without having confirmation that we wouldn't have the same problem 2 weeks later!

Zach was courteous enough (not overly so). He "set up shop" in the basement and worked on repairing the unit. He occasionally would give an update as to what he was doing. After his initial assessment, he said that he needed to return with a part. I needed to encourage him to check to see whether the unit was still under warranty, and I'm not sure he would have checked into this had I not brought it up. He returned two days later after a small scheduling mix-up and installed the new motor. He also pointed out some issues with the filters in the unit which appear to have led to better overall performance. He did a fine enough job.
Description of Work: Zach inspected the existing unit to get a sense of the issue involved. He initially thought it was an issue outside the building, but I kept suggesting that the sound was emanating from the unit inside the building. Eventually he agreed with my assessment. He inspected the unit and concluded that ball bearings in the motor were worn out. He replaced the motor with a new one.

Technician verified system in working order pre-season. In fact, one room never had heat because the bleed port on the radiator was not working and the furnace that supplies forced air to the same room was also not operative. Astonishingly, the technician had little understanding of how the heating system in the house was even configured -- for example, he was not aware of a second furnace -- despite having done the pre-season maintenance himself. After being called back to remedy the problem, he 1) unsuccessfully bled a radiator (it remains cold); and 2) attributed the forced air problem to a dirty filter (nonsense, and raises question as to why it was not replaced or reported at pre-season maintenance). Then he left leaving no filter in the furnace, after trying to charge me for the service call. I requested a follow-up call to schedule proper work when a technician had more time, and have received no response.

We have used Guardian several times for an annual check-up of our boiler. Every experience has been very good. The technicians are helpful and willing to answer all questions. We will continue to use Guardian for servicing our boiler.
Description of Work: The pilot light on our boiler would not stay lit. The technician determined that the pilot was bad. He replaced it ($76 for the part) and then did a thorough check of the system.

CASEY AND ZAN WERE PROFESSIONAL AND HELPFUL IN ANSWERING ANY OF MY QUESTIONS. THEY ALSO WERE CAREFUL IN KEEPING THE DUST AND DIRT TO A MINIMUM. THEY WERE PATIENT IN ANSWERING MY QUESTIONS AND WERE KNOWLEDGEABLE ABOUT THE NEW FURNACE AND ITS OPERATION. GUARDIAN HAS BEEN MY HEATING AND COOLING COMPANY OF CHOICE SINCE I MOVED INTO MY BUNGALOW EIGHT YEARS AGO. THEY HAVE ALWAYS BEEN ON TIME. THEY HAVE ALWAYS PERFORMED THE REQUIRED SERVICE TO MY SATISFACTION. I ALSO BELIEVE THEIR RATES ARE COMPETITIVE AND FAIR. BASED ON MY EXPERIENCES WITH GUARDIAN, I HIGHLY RECOMMEND THIS COMPANY.
Description of Work: GUARDIAN HEATING & COOLING MET WITH ME ON A SATURDAY MORNING TO GIVE ME AN ESTIMATE ON A NEW GAS, FORCED-AIR FURNACE. THE SALESMAN ARRIVED ON TIME AS SCHEDULED, WAS KNOWLEDGEABLE ABOUT THE PRODUCT AND GAVE ME PRODUCT MATERIALS, ALONG WITH A WRITTEN ESTIMATE FOR THE INSTALLATION. GUARDIAN ACCOMMODATED MY REQUEST FOR A CERTAIN DATE FOR INSTALLATION. TWO SERVICEMEN ARRIVED ON TIME, WORKED ALL DAY, INSTALLED THE NEW FURNACE AND HUMIDIFER, AND REMOVED THE OLD FURNACE AND ALL MATERIALS FROM MY PROPERTY. THEY ALSO ANSWERED ANY AND ALL OF MY QUESTIONS ON ITS OPERATION, ALONG WITH THE NEWLY-INSTALLED, "SPECIAL" THERMOSTAT.

I CALLED GUARDIAN BECAUSE THEY ARE A PREFERRED CONTRACTOR FOR RHEEM UNITS. THE INITIAL CALL WAS TO SERVICE MY UNIT AFTER I JUST MOVED IN. THE PREVIOUS OWNER HAD NEGLECTED THE UNIT AND IT NEEDED CLEANING. TURNS OUT, AFTER A NEW BLOWER MOTOR, NEW CIRCUIT BOARD, AND NEW COIL, I STILL AM HAVING PROBLEMS, DUE TO IMPROPER CONSTRUCTION OF MY DUCTWORK. MY UNIT ISN'T GETTING ENOUGH RETURN AIR. WE BASICALLY HAVE REBUILT THE UNIT. GUARDIAN WAS PROMPT, PUNCTUAL, AND MOST IMPORTANTLY HELPED EDUCATE ME. WE NOW HAVE A MAINTENANCE CONTRACT WITH THEM.
