Benefits of an Energy Efficient Space

Lower energy bills • Eliminate drafts • Reduced energy consumption • No more hot/cold spots

When a home or office considers whole-home performance when installing a quality HVAC system, air will be clean, and temperatures will remain consistent. There will be no air leakage that allows warm air to escape in winter or cool air to escape in summer. Moisture will be reduced from the air, so mold will not be a problem. You will feel completely comfortable in a space that is filled with healthy air at an ideal temperature.

Whole-home performance incorporates upgrades like insulation and efficient appliances that help save energy and lower monthly bills. The initial investment will be repaid in a short amount of time, and the environment will be preserved as well. You can gain reassurance that you are helping to reduce the country’s dependence on expensive energy.

What Kind of Home Energy Savings Can Be Achieved?

You are probably wasting energy without knowing it. However, by incorporating a few changes to your home or office, you will be able to reduce your energy consumption by as much as 40% — the amount will vary depending on upgrades selected. In a short period of time, you will notice a definite improvement in monthly utility bills.

It is essential for you to inspect your home or office and uncover ways to boost your energy efficiency. If you live in Los Angeles County, San Bernardino County, or the Inland Empire, do not hesitate to contact us for more information at (909) 392-2202.

Customer Reviews


I have been a customer of McLay Service for years and have always found them to be excellent! Recently, my water bill was quite high and I was very concerned that there could be a huge plumbing problem in my home. I called McLay Services and the response was fast! The service was thorough, efficient, and very affordable. After Brian ruled-out any house leak, he found the problem was due to the sprinkler system. The plan to remedy this was straightforward and honest. In addition to being helpful, he was creditable in informing me that while he would be able to correct the problem, my gardener would be able to do this for less cost. 100% for integrity, skill, and manners!

Chad is the very best service tech at Mc Clay and other better than other plumbing service tech we have used. He is nice and can troubleshoot any issues. He has come to our house and condo several times and he responds on time. He was able to fix our problem at home 3 hours after we called him on Saturday. I have to say the office staff was great as well, called us back immediately and scheduled the appointment. GREAT JOB TO ALL!!
