"I will preface this review by saying that I work as a general contractor (with regular interaction with mechanical contractors), work in the service and sales industry (as a personal trainer), and am a business owner (yes, three separate jobs in three separate industries). I say the above because I have the credibility to be able to write a review like this. On 10/3/23 I discovered that my AC (an Amana 3 ton, 36,000 BTU, R410a split system) was not blowing cool enough air to meet thermostat settings. As the original installation of the system was performed by Snell Heating & Air Conditioning [on 1/6/12], I decided to use them for the service call.  The technician (Franco) arrived on 10/4/23 within his scheduled time slot. Franco was transparent and clearly explained the process. Within minutes he was able to identify the source of the problem (the evaporator coil within the indoor air handling unit had frozen indicating a refrigerant leak). He presented me with three options: 1) refill the refrigerant at $715 per four gallons; 2) do a leak check to identify the source of the leak and replace the component from which the leak is originating (i.e. the coils at the outdoor condensing unit, the evaporator coil at the indoor air handling unit, or the line sets) for ~$7,000 and possibly higher; or 3) replace the entire system at anywhere from $18,000-$35,000. This is when I realized the 'sales pitch' was going to start. You see review readers, companies like Snell and others (that have been gobbled up by private equity firms and/or larger companies) no longer operate as a 'small local family business' where integrity, honesty, and doing what is best for the customer is the priority. Snell (which was acquired by Horizon in 2020) now operates as a giant selling machine. These types of businesses have large overhead, extensive marketing costs, training costs, fleet costs, insurance costs, uniform costs, IT costs, and much more that all need to be accounted for in their pricing. They simply cannot operate as such a large business if these expenses are not passed down to the consumer...and frankly, most consumers will happily pay it (as is evidenced by the hundreds of positive reviews). However, an educated consumer can be dangerous for these types of companies. Let me expand on what I mean here. For example, R-410a refrigerant costs <$400 for 25 lbs or <$15/lb (Snell is charging close to $200 per pound). An Amana evaporator coil costs ~$600 (Snell is charging close to $7,000). I won't even begin to tell you how much of a markup they are putting on a brand new HVAC system (it is astronomical). It is understood that their prices include installation, travel, warranty, and all of the aforementioned overhead costs, however, within minutes of their departure I found several small residential HVAC contractors that quoted the same items for fractions of the cost of Snell. Let me be clear, Franco was professional, courteous, and patient. He was an ideal employee for this type of business (a commission-based business where sales are the priority). However, the bottom line is this, Snell is part of the new wave of larger residential HVAC contractors where maximizing profit is the most important thing...and, you know what, I get it. As the old saying goes, "don't hate the player, hate the game". This is where we are in America - products/appliances/gadgets/devices becoming obsolete and having shorter and shorter life spans and businesses caring less and less. I am not some disgruntled 'Harry Homeowner' It is simply inexplicable to me that a system that was installed by Snell only 11 years ago (and just out of the ten year warranty period) must already be replaced. My hats off to David Snell and their entire team - they run a well oiled machine but I simply will not pay the type of costs they are charging."

"The repair work was well done. I had no idea it would take 2 people. The first quote was for a lower price but then they did not have the parts so I said OK to the more expensive option. But then they were not able to do the more expensive option so they went and got the part for the lower price option. But ultimately they charged me for the higher price option. I have called three days in a row and have not been able to resolve the price discrepancy."

Gas Leak Repair questions, answered by experts

Element, gas features, and complexity, including venting and connections, are typically higher due to safety and expertise factors.

Only yellow Teflon tape is approved for use on gas lines. Also called yellow PTFE tape, it is thicker and specifically rated for use on natural gas and propane connections. Standard white Teflon tape is not safe for gas applications. If you have questions about sealing gas line connections, contact a pro like a gas line contractor or plumber who installs or runs gas lines.

The easiest way to empty a propane tank is to simply use it until no propane remains. If you’re short on time and need a faster solution, transfer the propane to another tank instead. Wear leather gloves to protect your hands, then connect the hoses from both propane tanks and seal them tightly. Turn the knob to open the supply tank valve on the full tank and let it run until the pressure pushes all the propane into the other tank. When all propane is transferred, remove the hose and seal each tank. 

In most cases, yes, it’s safe to light a gas water heater manually, but you should shut the gas off first, open a window, and let the space air out for about 10 minutes. Modern water heaters shut the gas off entirely if the pilot light goes out, but airing out the area beforehand is good practice and will ensure it’s safe to relight your pilot light manually. Just make sure you turn the gas valve to “pilot” before lighting. If the light keeps going out or won’t light at all, call in a professional.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.
