I bought a new furnace and air conditioner a year ago in April 2015. Two free service calls were included in the cost of the system. In the past year I called a couple of time asking when service was needed as I was getting prompts from my digital thermostat well before the service to replace the air filter in the furnace. Turns out air filters should be replaced every four months. I was told by Specialty not to worry about the prompts and that the air temperature had to be high enough to test the air conditioner so I needed to wait a full year until April 2016. So I had the service this week on the furnace and the AC. At the conclusion of the service on the furnace and air conditioner (about 1.5 hours) I was told that Specialty had done both prepaid services at once (furnace and AC) so I now had no future prepaid service. Specialty also sent out the wrong sized filter which made no sense as they sold me the furnace a year ago and should have had all the specifications. They also told me the air filter was not part of the service and I had to pay an additional $30 for the new filter. The right filter then had to be delivered and installed. After the service the technician Scott told me I needed a "surge protecter" for the air conditioner compressor for over $200 in case of a power outage or I risked damage to the $3000 compresse. He also said I needed to prepay for future service appointments (more than $300) or my equipment warranty would/could be voided. I have been in this house for 38 years and have never needed a surge protecter for my AC compressor so that was obviously bogus. And since my system is a year old and I just had it serviced I doubt I my system warranty would be voided if I did not prepay for a maintenance that is not due for six months to a year. I have generally liked Speciality and had a good sales and installation experience. What I have found is that after the sale there is often a hard sell on the customer for unneeded services. When I had Climate Control it was a $730 air filter that needed to be installed into my return air ducts which was totally bogus. I fired Climate Control after this bogus hard sale sales pitch. So I was not happy with the bogus hard sell after my service. I declined both the surge protecter and the prepay on future maintenance. I had just fully paid off my expensive furnace and air conditioner this month so was not amused over the effort to try and extract $30 out of me for a air filter that should be part of any furnace maintenance or an extra $500 for a surge protecter and a prepaid maintenance that is not yet due.
