"He was supposed to start on November 9 called off and did show up on November 10 to install the thermostat that I provided. He worked on it for couple hours and then told me that the thermostat was faulty. He told me to return it and he would buy one and return the next day. After he left, I noticed one of the prongs were bent and I straightened it out and the thermostat worked and the heater kicked on. He still maintained that it was faulty, so I did return it and he came back with one exactly like it the next day. I reimbursed him for that. Again, he worked on it for a couple hours and the same issue that we’ve had from the beginning of the fan not turning off remained. He told me that there is no way it’s wired wrong so it has to be in the unit asked for payment which I gave him $125 in cash. I might add that he used my tools which I found quite odd. I ended up having to call out another contractor because he told me it had to be the unit. Cliffs informed me that there was absolutely nothing wrong with the unit and he even referred to it as “Cherry“ He checked everything out and then asked me about the thermostat and I said it was brand new and installed through Angi. He took the cover off and in a split second said I see exactly what the problem is. It’s c wired wrong. (THIS WOULD MEAN THL WIRED IT WRONG TWICE) He pointed out the green wire should not be connected at all. That is what is making the fan run continuously. He disconnected the wire and it worked perfectly. This cost me $218.00 for the service call/tune up."

Central a/c service or repairs FAQs

Yes, a once-a-year tune-up keeps the system efficient and helps it last longer. During the visit, a technician cleans coils, checks electrical connections, and swaps or cleans the filter. Catching small issues now stops bigger, pricier failures later, so that a quick appointment saves money and stress over the life of the unit.

Changing your AC filter every 30 days is necessary to maintain optimal performance and high indoor air quality. Regular filter replacement prevents dust buildup, ensures efficient airflow, and protects the system from stress that could lead to costly repairs. This disciplined maintenance routine not only boosts energy efficiency but also prolongs the lifespan of your unit by safeguarding its critical components.

An HVAC service plan is worth the cost, especially if you forget to schedule maintenance on your own. A service plan locks in yearly (or twice-yearly) visits, allowing a professional to identify small problems early, clean key components, and maintain energy efficiency. Many plans also include minor repairs or priority scheduling, which can pay for themselves if an unexpected issue pops up.

In a pre-season service visit, your technician gives your system a top-to-bottom check before peak season hits. Expect a filter change, thermostat test, condenser-line flush, electrical-connection check, and coil cleaning. They also tighten loose parts and make minor adjustments so the unit fires up without surprises when temperatures swing. That quick tune-up cuts the risk of mid-season breakdowns and keeps energy use in line.
