"Very pleased with his work and prices and was very prompt from the time I talked to him initially to getting the unit ordered and getting it installed. Cleaned up after and hauled off old unit. Would recommend him to anyone looking to replace their old havc equipment. R Stafford"
Framing the support structure for a second-story deck addition. Pressure-treated posts and beams being installed to extend the outdoor living space and reinforce structural integrity. Project located in a residential backyard setting with access to existing patio slab.

"After a frustrating experience with another HVAC company, Cochran was a breath of fresh air. Communication was always consistent. He was here when he said he would be, and when he had other jobs going long he made sure to call me. He was upfront about costs and options for our failing unit. There were a few minor hiccups along the way that came with being a smaller business, but the customer service more than made up for it. Great value for the money. Would certainly recommend."

"I did have Davis & Son repair my Heating system and they did a very good job. When I called to have them install a gas line (about 10 feet), they were going to get back to me with a quote and timeline. That was a month ago - nothing. I called and had another firm complete the work in 3 hours. Disappointed that they never called back."

Heating and Air Conditioning questions, answered by experts

An HVAC unit, like a furnace, air conditioner, or heat pump, produces warm or hot air. The air ducts serve as the passages to help heat or cool air from the HVAC unit flow through the home. Air ducts are just one part of the overall HVAC system.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.
