Dear Sig and everyone else,…read more You did a great job! Our furnace was very old and needed replacing. Thanks very much and we will recommend you to our friends. James and Monica Jones Five stars!

We recently moved from Chicago and I cannot say enough good things about Frank. I'd give Sig's 10…read morestars if I could. We had two older HVAC units, and so we had Frank come service them each year. He also came for service calls when they would short cycle or otherwise not work properly. Given the age of the systems, Frank could have told me it was unfixable and I would have believed him. But he is so honest and knowledgeable and always was able to fix it right away. He is just really nice, too -- on one visit, it was my son's birthday. He had to go get a part and came back with a card and hot wheels for him. Frank is the absolute best! I wish he would have moved with me, ha!

My water heater went out. The company that "diagnosed" the problem charged me $99 and said that…read morethis did not include the cost to replace it. The company then quoted me $2200 as the cost to replace it and reiterated that this did not include the $99 that they already charged me. So yes, had I gone with that company, it would have cost me $2300. Armed with this information, I posted pictures and exactly what the "diagnosis" said and asked for emailed quotes...to be clear I said EMAIL only. I then got no less than 10 phone calls saying "please give us a call so we can talk about your situation. Some called more than once. Lakeland Heating and Cooling (Jason) was nothing like that... $1270 flat rate to replace the water heater. Yes, thats how he replied in his email.. as I requested. He came in.. with the water heater... replaced it... and went on his way. Other companies, that followed directions, also came in higher than $2000. I am EXTREMELY satisfied with Jason and Lakeland! High Quality, Tremendous VALUE

Even though we hadn't adjusted the thermostat settings, we were unable to understand why our energy…read moreexpenses had been gradually increasing each month for some time. We requested a comprehensive home energy assessment from this company. They went above and beyond what I had anticipated, a simple once-over. The professional tested HVAC performance, insulation levels, duct leaks, and even conducted a blower door test to find leaks and drafts for several hours. He compiled a list of fixes based on potential savings and produced a detailed report including thermal photos. We improved the attic insulation and sealed the ducts. The improvement has been amazing--the home stays more consistently conditioned and our heating and cooling system operates less frequently. We have already observed a 25% decrease in our utility costs. In addition to selling us equipment, They truly stand out for their expertise and transparency.

Called to schedule an appt. for A/C maintenance and humidifier pad replacement based on Yelp!…read morereviews.
