"Outstanding company! The owners are mechanical engineers and were able to figure out why a unit previously installed by another contractor caused mold in my ductwork. They completed a Manual J calculation report that indicated the unit was too large, and they replaced the unit. Previously, this contractor identified that the static pressure on both of my HVAC units was too high and appropriate adjustments were made. All employees are professional, knowledgeable, friendly, responsive and extremely helpful. Hands down, this is the best HVAC contractor I have ever worked with."

"The team arrived exactly on time and got the job done in about 8 hours. Had them remove my 23 year old HVAC system and upgrade from undersized 3 ton to a 4 ton Tram. I also had them remove and replace all my ducts and replace. Great work fantastic communication and service. And the price came in well below the next highest bidder out of 5 bids. With the highest being nearly double!!! Can’t recommend this company enough. And thank you David Flores’s for answering all my last minute questions"

Heating and Air Conditioning FAQs, answered by experts

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

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.
