Rest assured, a factory trained and NATE certified HVAC professional is using calibrated digital gauges to ensure safe, efficient, and reliable operation that is backed by a lifetime workmanship warranty. All employees are drug and background checked and do not work on commission. 'We Hire The Best For The Best!'

"I wished we had known about the Integrity sooner instead having waisted time with other companies. Our last AC guy was trying force us to agree getting another AC brand for an insane price. He thought he would convince us once it was during the hottest wave we have ever had.We just wanted to make sure we could get not only a better estimate but know what else the market had to offer us. Since we know Costco has a reputable name in the market, we felt we should take that path. Certainly Costco would have a trustworthy partnership with an AC company. We got 3 estimates before Integrity. None of them I felt confident in going ahead.Even with a lower estimate. As soon as they called me to schedule the visit, I told my husband we probably had found the right direction.Ortiz came and took care to hear our needs and he did not try to sell us anything else other than we really needed. Everything he told us we were aware. He was very clear, profissional and easy to deal with. Actually the whole process with Integrity was absolutely easy to deal with. Everyone I had to speak, email or get in touch was responsible, clear and very kind. The installation crew was amazing. We had Dan, Abraham, Bryce and another guy I forgot his name.This one was super nice with my son talking about games. We are very impressed with the quality service Integrity has, and the way they deal with their customers. Keep doing this excellent job. Nail was so very attentive with me answering my questions all the time. We are more than happy to have chosen Integrity to take car of our HVAC from now. Definitely the name Integrity speaks itself. Thank you for working with us since the beginning process to the end with so much care. We feel so much comfortable now knowing we have a trustworthy and integrity company to take care of our system. Please keep doing this excellent job and your company will be always on the top of credibility, for sure."

"Work has been scheduled for early in 2019, but they could not have been more helpful and professional in explaining our options, how our home would get the most out of the panels, and how much we are likely to save. They were explicit about costs and available rebates. We were instructed to apply for a rebate from our local energy supplier and they literally walked us through the time specific rebate procedure. We made some minor changes to their standard contract and they accepted those changes without question. I can only assume their work will be up to these standards when we do the actual installation."

The install team did a great job and it has given our home a true facelift. They replaced a sliding glass door with three beautiful windows in my breakfast area, and we are so happy with the new look. They were very courteous and careful when they were working inside our home and cleaned everything up and hauled it off. We are looking forward to lower energy bills the future.

Solar Energy World is a top-rated solar system design and installation company for residential and commercial property owners in Maryland, Virginia, Pennsylvania, New Jersey, Florida and Washington DC. Our mission is to give more people the power to reduce their dependence on dirty energy to foster financial and environmental security for their children and grandchildren because we believe tomorrow matters. We have installed thousands of solar panel systems since our founding in 2009. Solar Power World, the industry’s leading source for solar technology, development and installation news, released their annual Top 500 North American Solar Contractors List in July 2019. Our company made the list again achieving a rank of 85 for total Kilowatts installed in the USA in 2018, moving up from our previous ranking of 117. We also improved our rank of number 24 for total residential kW installed in 2018, now ranking 15 on the list nationwide and have held on to the number one spot for residential installations in Maryland for the third year in a row. In just 10 years we have gone from installing 8-10 solar systems a month to an average of 140 installs a month, making us the fastest-growing, independently-owned Solar Installation company in the region.

"Beware of hiring Solar Energy World I hope this helps someone else avoid the problems that we have been facing with this company. Initially we thought what is the catch, this is too good to be true... well it is. Our panels were incorrectly installed leaving holes in our roofing which led to water pooling in our front porch ceiling and running down the face of our house. We ended up with warped front porch flooring along with mold and water damage in our finished basement. After almost 4 months of us having to follow up weekly and them coming out to correct their improper installation they are now saying that they are not liable for any of the damages to our home. The manager told me that because we moved forward with the mold remediation that they aren't liable. How can a company expect people to live in a home with mold for 4 months while they "review" the situation. The manager then slipped up and admitted that they never reviewed the photos or invoice that I sent over, they just decided in a brief discussion that they werent liable for the damages. When I asked to please speak to the manager that made the decision I was told that he is a difficult man to get a hold of so that won't be possible. I am just shocked and disappointed in this company. We have been so patient and understanding during this whole process to have them treat us like this. Just go elsewhere if you want a company that will do right by their customers because Solar Energy World is not that company."

Energy Efficiency Auditing questions, answered by experts

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.

HVAC systems use the most household electricity. This major and essential system is responsible for heating and cooling your home all year round. Since they operate for a significant amount during the day, it consumes more energy than other appliances. 

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.

Dryers are designed to use as little electricity as possible, but power is still required to run the motor that turns the drum and to heat an element that pumps hot air. Eco devices are available and may lead to cost savings in the long term, but you should run the figures before committing to an eco-friendly device as they are often much more expensive to purchase.

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.
