We’ve been using Campbell’s HVAC services for several years now. They maintain our heating (during the fall) and cooling (during the spring) systems. Our HVAC units are getting older, but so far, the maintenance on both units has been minimal. I feel it’s an honest, hard-working company. Matthew has been our tech for all of the visits and he’s always so pleasant to work with. Matthew comes across as honest and extremely knowledgeable about HVAC. At the conclusion of each visit, he always asks if I have any questions about the work that was done. I learned that using the correct Merv rating for the system you have can keep it running better. He explained that to me the first time he came to do maintenance on our systems. That may be a factor in why it’s still running well.
