"Thermatech was the very first company to respond when I reached out on Angie's List I booked them to come out and give me an estimate when the tech arrived about 2 hours later he found that the control board had caught fire and some parts needed to be replaced initially the estimate I thought was a little on the high side so I was going to get another quote how about 30 minutes later I got a call from the office stating that they found the parts cheaper and gave me a another quote which I found to be very reasonable and I booked them to do the job the very next day they were there in the afternoon and fixed my furnace I am very happy with their service and their pricing was very reasonable I would recommend them the tech Jeremy was very efficient and very nice"

I've been in the trades since I was 15, looking for opportunities to grow my buisness after moving to a new area recently. We generally are a group of full time contractors, engineers and project managers that like to get our hands dirty. We work fast, do everything in house, work flexible hours and pride ourselves on affordable pricing.

"I recently had the pleasure of working with Emerald Bay Design and Construction for a major renovation project, and I couldn't be more impressed with the craftsmanship. From start to finish, they demonstrated a deep understanding of design and construction techniques, delivering outstanding results that exceeded my expectations. Richard took the time to understand my vision and translated it into a beautifully crafted reality. Communication was clear and timely throughout the process and I received my bid back quickly and accurately. Overall, I would highly recommend Emerald Bay Design and Construction to anyone looking for a design and construction company. I am thrilled with the results of my project and look forward to working with them again in the future."

Heating and Air Conditioning questions, answered by experts

On average, the cost to repair an air conditioner hovers around $350, but it can cost anywhere between $130 to $3,000, depending on the type of air conditioner and the difficulty of the repair. Repairing an air conditioner yourself can still be costly, requiring specialty tools. Any repairs more complicated than replacing a filter are likely best left to the pros.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.

Assessing location for airflow, convenience, and minimal noise impact.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.
