"I hired this company to put in a generator after seeing their commercials on TV, and seeing all the high reviews online. I can say that my experience has been horrible. First off, the permitting process took months, just to get the approval to install the generator. After the install, city permitting workers came out countless times sighting issues that needed to be resolved that seemingly didn’t get resolved because they’d get flagged again for the same issues. The biggest being they installed the generator too close to the natural gas line, which caused them to move the generator over about 18 inches and needing to install a giant junction box on the outside wall of my house. Not a great look. During the install and clearing permits, it’s almost impossible to get ahold of anyone to get a status update. I’d call and leave messages, email – repeatedly – before I’d finally get someone to reply. Fast forward a year, I discovered they installed one of the junction boxes incorrectly to my pool heater, causing it to fill up with water… so another repair. Now after the first year they hit you with a $600 per year contract to continue to monitor the generator for issues. Even after I signed it, I still get an email asking me to sign up every couple of weeks.. I’ve responded a dozen times telling them I’ve signed up for the monitoring program and to stop emailing me. Now the icing on the cake. I’m paying $600 a year for them to 'monitor' for problems. Today we lost power and the generator didn’t turn on. Looked at my mobile app, and it shows the cell signal used to monitor the generator isn’t working. I open the generator and the control panel that runs the entire system is blank and not working. Obviously a major problem… and isn’t that why I’m paying $600 a year for Reliable to monitor for problems and fix them before they cause an issue? This monitoring program is a scam. If they were actually monitoring the system they would've seen that my generator didn't exercise on Monday as scheduled, and that I've been offline over a week! Calling to ask that question just got me on the line with some low level customer service person, who can’t do anything but set an appointment a week from now. If you’re going to install a generator, look elsewhere."

"It breaks my heart to write this. We have used Liberty Air for 10yrs for both our business and home air units. They have always been without issue. I called them out about 4 or 5 days ago and they said he didn't know why it wasn't working but he said there was water in the pan, so the drains maybe needed cleaned. Well, $500 later, it just isn't working. So I call them out again. The second guy catches it within a min literally of being there. He said both our units had hair clogged in both and they really needed done. Well that'll be an additional $900. I was extremely upset. I didn't have the first $500 more less an additional $900. The only thing they offered was not to charge the service fee to come out that second time. I am furious. We have been VERY loyal and we are honest people. I wasn't expecting free $900 worth of work, however to not even admit fault or offer any discount for the work they should've done and caught day 1 day one is unacceptable. I am a small business and when we are in the wrong we make it right. Do not trust these people."

Heating and Air Conditioning questions, answered by experts

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

The cost of annual maintenance depends on the type of HVAC system you have. AC service typically costs an average of $200 but ranges from $100 to $550. If your system needs repairs, the price will vary significantly depending on what needs fixing. However, addressing the issues as they arise can prevent further damage to your unit and keep it operating efficiently for much longer.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Next, find the “reset” button on your AC unit and hold it for three to five seconds. The unit should beep several times. If your air conditioner doesn’t have a reset button, leave the circuit breaker off for 30 minutes. Afterward, turn the power back on at the breaker and program the thermostat to “cool” to test the system.

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.
