On Jan 16th I called CLOVER HVAC service because my HVAC was shutting down and home wasn't heating. They sent two technicians to home in short time. They observed the code 31 or 13 flashing on the carrier HVAC and told me it’s the pressure switch that is faulty. Since they claimed they were licensed and experienced technician I trusted them and paid $478 in total ( $99 for the visit + $379 advance payment o replace the pressure switch for next visit ). After they left, the HVAC system was working, blowing hot air but doesn't take break when indoor temperature reaches thermostat set temperature. (This is quite dangerous for multitude of reasons). It was like furnace inside the home. I called them to visit home and check. They suggested, I should attempt to fix while they instruct me how to do it on phone. WHAT A WORST IDEA. JUST to keep my property safe I attempted it with lot of hesitation and fear of the furnace. Then I see the furnace started accumulating water quite close to the electric/mother circuit board. I was scared because its basic electrical 101, water with active current is a worst scene. They came back on the same evening and fixed it. I was really unsatisfied & frustrated and called their office and ASKED THEM "PLEASE CANCEL MY NEXT SERVICE OF REPLACING THE PRESSURE SWITCH" because of their inexperience and the mess. They told me that they will refund that day visit cost $99 and will send a senior technician to do "FULL SYSTEM DIAGNOSTIC CHECK AND IF AT ALL NECESSARY, THEY WILL REPLACE THE SWITCH". I didn't like the idea but I finally agreed after they repeatedly declined to cancel the next appointment with them. Then the senior tech came and couldn't really pinned down the issue and replaces the pressure switch without concrete evidence. The HVAC ran fine for 4 days and on fifth day it started flashing the same error code 31 or 13 . I called them and they sent same senior tech again as soon as they could. At this visit he claimed he did what he should have done in his earlier visits . i.e HVAC 101. ANY LICENSING SCHOOL WOULD TEACH THIS, WHENEVER HVAC FLASHES PRESSURE SWITCH CODE YOU SHOULD
1) OPEN THE BLOWER FAN, CHECK FOR ANY CLOGS, DEBRIS AND CONDENSATE LIQUID? THEY DIDN'T DO THIS. NOT EVEN TOUCHED IT.
2) CHECK EXHAUST, INTAKE AND DRAIN PIPES TO CHECK FOR ANY CLOGS. THEY DID EXAMINE THIS.
3) CHECK THE ELECTRICAL COMPONENTS FOR ANY ISSUE. THEY TESTED THIS.
WHY DIDN’T YOU CHECK THE BLOWER FAN?? WAS IT TOO SIMPLE AND DOESN’T COST MUCH TO CUSTOMER?
The HVAC stopped working again for the second time and this time knew I will be a total fool if I call them because $379 + three CLOVER technicians + four visits couldn't fix it . Either they knew what was the problem and they choose not to operate and scam me by replacing a well-functioning part or they don’t know above point (1). By looking at the below attached pictures and not doing HVAC 101 point (1), you might be convinced the first case is likely true. i.e they wanted to do something which would bring more money and not doing simple cleaning which could have done during their first visit for just $99.
After waiting for two cold nights a genuine technician came and said there is nothing wrong with the old pressure switch (he tested it by replacing it) or another component. AND just the ducts and pipes needed further cleaning. IT has been a couple days it’s working.
I called them for a refund since they claim "MONEY BACK GUARANTEE” if their service was unsatisfactory. SINCE YOU COULDN'T FIX THE PROBLEM AND DIDN’T DO THE BASIC CHECK IN YOUR FIRST VISIT YOU SHULD REFUND. They tell me, they already gave $99 discount and cannot offer any further discount. I WANT TO REMIND; YOU GAVE ME $99 BECAUSE YOU PUT MY WHOLE HVAC AT RISK BECAUSE OF THE WATER LEAKING FROM THE EXHAUST Pipe. IT WAS YOUR FAULT. YOU DIDN’T DO A FAVOUR TO ME. Now I am asking for refund because even after four visits and charging me $379 you couldn't fix the issue AND REPLACED A WELL FUNCTIONING PART WHICH WAS TOTAL UNNECESSARY.
You break my confidence and trust.

I had an emergency leak in my bathroom sink right before the end of business day, and Brad was able to walk me through stemming the flow of water over the phone and came right away to fix the problem. That is the second time he has helped me with an emergency leak. He does an excellent job! Very happy.
