Hear From A Recent Customer

Of course my heat went out on Sunday. I contacted Leith and got a call back from Matthew, the technician, immediately. He came out within the hour and diagnosed the issue. Unfortunately, the part my furnace needed was not something they had in their truck (it's not a typical fitting for the part). He was able to tell me the part was in stock at the supplier, the price and that they would be placing the call for the part at 7:30am the next day. As promised, they completed the job on Monday. The house is toasty warm thanks to Leith Heating. Matthew was polite, knowledgeable and made sure he answered any questions I had. Leith has been servicing my heating and cooling systems for years. They are trustworthy, knowledgeable and safe during Covid. Give them a try if you haven't, you won't be disappointed.
