Your Peace of Mind Always Comes First

We Stand Behind Our Service 100% –
That’s Why We Put It in Writing!

Standing By Our Promise to You

The Lewis MacLean family of written guarantees offers you the ultimate in peace of mind during every step of the process for repairs, installations and inspections. We cover everything from the high quality of our workmanship, to the premiere products we use, to how gentlemanly our Technicians conduct themselves while in your home.

Our 100% Satisfaction Guarantee States:
If you are not satisfied with our service in any way, we will correct the problem or you don’t pay.

It’s as simple as that!

CEO Clean Guarantee

Plumbing, heating and air conditioning repairs and installations can be a messy business, but our Expert Technicians will make sure you never have to clean up after we’ve been in your home.

We Always Treat Your Home with Respect – It’s Guaranteed!
Our written guarantee ensures that our Expert Technicians wear protective floor savers, use drop cloths, use HWT protective film, and leave their entire work area in pristine condition after a job is completed.
If you aren’t satisfied with the condition of your home after one of our jobs, our CEO will come to your home and clean it herself. That’s her promise to you. That’s peace of mind.

Product Replacement Guarantee

Here at Lewis MacLean Plumbing & Heating, we have full trust in the products we install, and we back this up in writing.

If the equipment and/or fixtures we have installed in your home do not perform as we have stated, during normal use in the first year, we will either repair or replace the item at no charge to you.

We can offer this guarantee because all of our products have been tested in the toughest places we know – our own homes. If a product can’t survive there, we won’t install it in your home.

Property Protection Guarantee

This “ Ultimate Peace of Mind” guarantee states that your home will always be protected from damage whenever one of our 24 hour residential plumbing, heating, or air conditioning technicians is there on the job.

If they fail to do so, we will repair any damage without charge and supply you with a complimentary exclusive three-year membership in our Standard Lewis MacLean Club.
We can offer this written guarantee because we train, train, and re-train, all of our Techs in the art of treating your home with the care and respect it deserves – every time!

Lewis MacLean 24/7 Guarantee

We know plumbing, heating, air conditioning and drain emergencies don’t always happen during regular business hours — they often strike when you’re least prepared!

That’s why we guarantee that your call to us will be answered by a real live person 24 hours a day, 7 days a week, 365 days a year. You will receive immediate, knowledgeable support from a client care specialist to help you deal with your emergency. If, for any reason, you do reach our voicemail because we’re helping someone else, we guarantee your call will always be returned promptly! We’re here to take the stress out of your emergency.

100% Satisfaction Guarantee

They are trained to listen to your needs, to complete the work you require in the most professional manner, and to always give your home the “white-glove treatment” it deserves.
Our “100% Satisfaction Guarantee” means you must be satisfied with our staff and the quality of their workmanship and service – and if you’re not, then we will correct the problem to your satisfaction or you don’t pay.

The Best Experts Guarantee

We employ only the best in the business. We call it the 99% difference, because only the best are are qualified to be one of our 24 hour, expert residential plumbing, heating, and air conditioning technicians.

Each employee has to pass through a battery of background checks, and in-depth interviews, before we will hire them. All of our highly trained technicians are drug tested and back-ground checked for your safety. And they are trained, trained, and trained again, to provide only the best service to all our clients. They are polite, clean-cut, and friendly. They will never use profanity or smoke in or around your home, plus they will always clean up their workspace, so you won’t even know they were in your home.

And the quality of their workmanship is the best in the business. They are skilled at not just repairing the problem, but discovering the root cause to ensure it doesn’t happen again.
We guarantee every aspect of our staff’s performance or we will do whatever it takes to make it right.

I guarantee it!

The Bottom Line Guarantee

People talk. And when you talk about Lewis MacLean, we want those words to be that you were thrilled with the service you received. Word of mouth is important in the plumbing, heating and air conditioning industry, which is built upon referrals. Your satisfaction builds trust as part of a long-term relationship. If you’re satisfied, you’ll call on Lewis MacLean again in the future, and you’ll pass on only good thoughts to those around you, when they are in need.

That’s why making each customer 100% satisfied is so important to us. For the last 50 years we’ve built our reputation on that trust. Trust – that’s the bottom line here at Lewis MacLean.

The Five Year Comfort Guarantee

The temperature you desire in your home should be the temperature you feel when you set your thermostat. Accuracy is vital for your comfort and for maximizing your energy costs. We will ensure that accuracy.

We guarantee in writing that for a full five years there will be a temperature variance of no more than plus or minus three degrees of design specifications for your thermostat. If the numbers go beyond that figure, a technician will make the modifications or repairs, and if necessary, replace the system at no charge to you.
