"The technician came out yesterday, June 5th and did a diagnosis on my air conditioner as there was a significant cooling disparity between the upstairs and downstairs of our two story townhome. I was expecting to possibly replace the A/C as it is getting older. However, the technician stated the AC is in good working condition and that there was a slight leakage factoring into the cooling discrepancy. That was a much less expensive repair or fix vs. replacing the whole equipment. I appreciated his honesty, time spent communicating the issue with me and professionalism. I would definitely use All Temp Heating and Air Conditioning again and recommend them to anyone dealing with air conditioning issues."

"Thought it was a plumbing issue, but turned out to be an issue with air conditioner. They were prompt in responding to the emergency call. HVAC responder was knowledgeable. Price for furnace and AC was horribly overpriced!"

Air Conditioning questions, answered by experts

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.
