"Had new hvac, furnace, and hwh installed. Furnace had a couple of air leaks between a coil and furnace which I fixed myself. Hvac was spot on. Hwh failed first inspection, but was corrected in same day. For the premium price paid, these issues should not happen. Quality 4.5 because of these issues, same goes for value. Customer service is very good. They are very professional, work looks very good, clean worksite afterwards. I would recommend, but don't think about negotiating price with them. Their labor is very high."

"HIGHLY RECOMMEND! Did much research on companies 1st b/c I was aware of scams with duct cleaning. But this company is very legitimate professional - techs and receptionist, all the way around! Top quality service! On time and will answer any questions and explain it all in great detail? very polite and professional. And yes, they will take photos throughout if you want to see exactly the differences of before and after. I had bought a 1959 home which had never been cleaned. See my before/after photos. Before, I kept having to wipe off my counter tops a few times a day because they always felt gritty. After the duct cleaning, they stay clean now - A HUGE DIFFERENCE! The guys were awesome and went above and beyond by also helping me carry a heavy appliance from upstairs to my basement. Very nice guys! They cleaned up any mess before leaving, like they had never there. You will not regret using their service. Lower Price than others too! Thanks Danny & Cameron! Great Work!"

"By February 2012, less than a year after installation, I begin to have problems. So I called Mt Everest, and they come and fix things here and there, and I don't think much of it because other than the inconvenience of occasionally being too hot, it's not costing me too much money. =) Here are some of the receipts I could find... Mt. Everest - 2/16/12 - $194.12 Mt. Everest - 2/17/12 - $0.00 Mt. Everest - 2/18/12 - $0.00 --new company name-- Tiger - 1/22/13 - $210.00 (Became Club Member) Tiger - 8/16/13 - $0.00 Tiger - 5/16/14 - $0.00 (Waived/Warranty) Fast forward to October 2015, a little over four years after installation, I have a coolant leak somewhere that can't seem to get fixed, and Tiger has to keep recharging my "closed" system... the only difference is now I have to start paying for this service. (I guess Freon is expensive.) I start to panic because my family is undergoing financial hardships, and whatever money I once had went toward the air conditioner I purchased four years earlier. Thankfully, Tiger works with me on this, and I am grateful. However, they warn me that I will need to have the evaporator coils (???) changed out. EEEK! At this point, I am already $10,000 (plus) into this system, it is only four years old, and it is having major problems. Again, I have no money left, so I'm talking to lawyers, because from what I can understand from Tiger, it's a manufacturing defect, and now I have to pay Tiger tons of money (that I don't have) to fix something that shouldn't even be broken yet. (Warrenty still covered parts, but not labor.) Thankfully, Tiger comes through for me and I refrain from possibly taking legal action against manufacturers. On October 23rd, 2015, the coil gets swapped out. The technician thinks there might still be a leak somewhere, but nothing really comes of it. The parts are covered under warranty, Tiger is kind enough to waive the fee for labor. * * * * * The above gives Tiger five stars. I seriously had no money to pay them. I would have had to get a loan from somewhere. ...but... It is now July 18th, 2016, not even a year has passed since the installation of a new coil, and it is 74* in my house... I have the thermostat set at 70*. The temp coming out of the vents is around 68* - according to my meat thermostat. I have called Tiger, and we have an appointment for tomorrow. I fear that Tiger is going to tell me that I will need a recharged -- or new coils -- and I will have to pay them for service with money I still don't have. I'm praying everything still falls under a warranty. Pray for me, you all. I'll come update after my appointment and let you all know how it went. <3"

Heating and Air Conditioning FAQs, answered by experts

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.
