Best Water Heating Units in Columbus OH

I have had both my furnace and air conditioning units replaced by KMA within the past 5 years. At first I was impressed with how quickly they came, and how reasonably priced they were. For the next few months, things went pretty smoothly except for the fact that they didn't replace the thermostat when they said they would, and no matter how often we called to reschedule, there were excuses. In the end, we just stopped calling.Every time the seasons change and we need to switch from heating to air we have problems. Once again, our air conditioner isn't working. We had it looked at by a different company last year who said that we have a refrigerant leak. He put in $300 worth of new refrigerant to get us through the summer because we couldn't afford to have the entire system repaired. We had called KMA before we called the other guys but they insisted that it was our own fault, and that it was going to cost nearly as much to repair it as we had paid to put in the new system. There was no talk of a leak, of course. Just that my filter was dirty, so I had ruined the machine myself. They did charge me $500 to come out and allegedly clean out my entire system, though, which is odd because a month or so after that I found toys in the register that my daughter had when she was a baby. She was 18 at the time that I found them.We have also had to repair the furnace each year as well. I replace my air filter every month, and order them 6 months at a time. I also use my shop vac to constantly clean out the registers myself. But I'm sure that they will just insist that it's my fault that nothing works right. I know the truth, though.I'll be filing complaints everywhere and with every agency that I can to protect other consumers from the same nightmare that I'm now living in my 87 degree house, with a unit that is barely 5 years old. I don't even trust them to come out to attempt to repair their mistakes anymore. They should pay Columbus Worthington Air to fix it - those are people who know what they're doing!
