"Angi advertises that you’ll get an upfront, transparent price before you ever schedule with a pro. That was not my experience here. This company refused to provide even a ballpark estimate for a standard job — a 50-amp generator plug with an interlock — and instead wanted to charge a $69 “dispatch/diagnostic” fee just to show up. That’s not an upfront price, that’s a sales appointment. Very misleading, and not what Angi promises. I will be taking my business elsewhere."

"We could never recommend. We purchased a 26kw whole home generac generator a couple month back. They set it up and told us to run it 24-25 hours to break it in and they would come change the oil and make sure everything was working fine. At the time of install I was told not to install the app because it was junk. Hours after the tech left we did install the app and after running the remainder of that day of install and throughout the night we manually shut the generator down at 22 hours as we noticed the app was showing the battery was discharging all night and the motor sounded like it was misfiring and had an exhaust leak. The technician came out and found a wire was hooked up wrong and then pulled the spark plug to show me it was fouling out, that wasn?t an exhaust leak, the rocker arms that push the valves down were pretty loose on one side of the engine. He removed the valve cover and tightened the rocker arms down using feeler gauges, yes I watched, and he reused the old valve "

"From the estimate to job completion everything was professional and on time. LHS left my house as clean as they found it. I’ve already noticed a drop in humidity and my Air conditioners are cycling off more often. I placed a thermometer in my attic and there’s close to a 40 degree difference between before and after the spray foam insulation. Job well done."

Comfort Engineered Systems Inc. We go beyond cooling to provide other needs as well. We also specialize in the following: GEO Thermal HVAC Generators Solar Panels Certified Cleaning Program Expert System Air Filtration No matter your needs, from generators to solar panels to geothermal HVAC systems, services, sales, and installing all of the above, we are here to provide the expert work you desire.

"I left a $9,000 deposit with Comfort Engineered Systems over 11 months ago to have a home generator installed. 6 months passed without any follow up by the company. I then placed 15 calls/messages to the company’s voicemail and answering service without ever receiving a single return call. I was finally left with no choice but to physically show up at the company’s office and demand to speak to the owner (Edward Perez). He claimed he never received any of my call and “just by coincidence” I was “next on the list” to have a generator installed. Five more months went by without any contact from the company. I placed another dozen calls to them, none of which were returned. Again, left with no other option I again had to physically show up at the company’s office to get a response as to why I was being completely ignored after having left a $9,000 deposit. When I got to the company’s office it was completely empty although the company’s name was still on the door. Fortunately there was another tenant in the building who informed me that Comfort Engineered had vacated the premises several months earlier and he thought they may have moved to Harrahan. The company’s website still listed the previous address so I had to do some detective work to find the location of their office in Harrahan. I again physically showed up at the company and requested a return of my deposit since over 11 months had passed, I had never received a single communication from the company and they were continuing to ignore my telephone messages. I would like to hand my full deposit returned so that I can move on with my project with someone else. Mr. Perez told me that “we do not return any deposits after 3 days” and again, by coincidence, I was “next on the list”. I told him that if I did not receive a refund of my deposit I was going to pursue legal action and walked out. Mr. Perez ran after me in the parking lot saying he could install my generator next week. Mr. Perez is the most dishonest businessman I have met in 30 years of doing construction/renovation work. Stay away from this guy like the plague."

Energy Efficiency Auditing questions, answered by experts

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

ENERGY STAR®-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR®-certified windows lower household energy bills by an average of 12% annually.

Yes, most audits include a report with prioritized recommendations for improving energy efficiency. Confirm with your auditor.
