"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 are a full service Air Conditioning and Heating Company. As we prove, "If we can't fix it, it can't be fixed!". We also offer regular rates all day long, this means NO OVERTIME (EVER)! However, we can only work on your air conditioner during the daylight hours. Now your furnace is different though. We can work on your furnace in the middle of the night in case of an emergency or frigid temperatures. Although we can fix just about everything, we also install both cooling and heating equipment. With over 20 years experience, no overtime, the best warranty in town, and the least expensive prices in town, why call anyone else? We also do hot water tank repair and replacement. Angie's List Members receive a $49 diagnostic and 10% off the repair with paid invoice onsite on repairs only. (Cannot combine with Senior Discount 10% on repairs only) http://www.cool225.com

"Perfect. On time on budget."

"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."

Energy Efficiency Auditing questions, answered by experts

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.

Installing weather stripping or upgrading to insulated panels can improve efficiency.

Some types of electric fireplaces use more electricity than others. Models that produce 1,500 watts will have more of an effect on your heating bill than 750-watt models. 

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

Yes, Tesla Powerwalls are worth the upfront costs, as you can recoup your investment within six to eight years. Plus, they provide peace of mind that you'll have power during a power outage, and, depending on the system you install, you can become energy-independent. While they may be more expensive than other solar power systems, they offer higher battery capacity and lifespan.
