"Another HVAC company diagnosed that my AC unit had a leaking evaporator coil after doing a pressure test, they quoted me over $1900 for labor and installation, claiming that my evaporator coil part was difficult to get a hold of.  I called up several other highly rated HVAC companies on Angie's List, all of whom told me that the part would not be difficult to get.  However, some were booked past Memorial Day, and others stated that they couldn't give me a quote unless they came out to actually look at my unit.  All Temp was the easiest to deal with and the most reasonably priced!  I called on May 22nd, they said they could come by on the morning of the 24th, I gave them the measurements and requested specs of my unit over the phone, and they quoted me $1075 right on the phone.  Troy came by on Saturday morning and installed the evaporator coil efficiently, and the price quoted was the price paid.  Couldn't have been an easier transaction.  He also could've been like the original company, who recommended replacing my units to try to get more money from me, but he was extremely honest and told me that with the new evaporator coil in there, I should be able to get many more years out of my unit and shouldn't even think about replacing it.  Thanks for your honesty and great service at a great price!

"Buyer Be Aware: If the Person doing the work tells You that you Cannot Use Your Credit Card (if After 5:00 PM), Do NOT Listen! Pay the Following Day during Business Hrs.!! Also, when my New HVAC System was being installed 2 Days After Duct Cleaning, the HVAC Contractors called Me into the Basement and Showed Me the Inside of the Ductwork just after Opening it: Tons of Debris Remained Inside! Hopefully, if You Hire, Your Experience Will Be Better...Good Luck!"

"In May of 2021, CR Mechanical replaced our HVAC equipment (furnace and AC), and installed a new air scrubber and an ecobee thermostat. We were very satisfied with their work (exceeded expectations), and Craig is an excellent installer (that was most important to us). The ecobee was defective out of the box, and he reinstalled our old thermostat and was back the next day (as promised) to install a replacement ecobee. Everything works great."

Heating and Air Conditioning FAQs, answered by experts

During the summer, it’s best to set your AC to 78 degrees when you’re home and awake, according to the Department of Energy (DOE). For better energy efficiency, raise the temperature slightly to 85 degrees while you’re out of the house. The National Sleep Foundation advises lowering your thermostat to between 60 and 67 degrees when you’re asleep.

No, you should not attempt to replace an AC evaporator coil yourself. This is a complex task that must be performed by a licensed HVAC technician. The process involves handling hazardous and flammable refrigerants, which poses significant safety risks. Attempting a DIY replacement can also cause further damage to your HVAC system and will likely void its warranty. It is necessary to hire a local AC repair professional for this job.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.
