A detailed written report, sent via e-mail, of any problems found while performing our maintenance service will be provided, along with itemized pricing for the recommended repairs. Should you move forward with our recommended repairs,  no “Trip charge” will be assessed on the return visit.

Additionally, we offer a range of maintenance service contracts, structured to fit your needs and budget, all but eliminating costly emergency repairs. See our Contract Service page for more details.


Unforeseen breakdowns are a nuisance and an inconvenience to your tenants. M & S Heating & Air gets you back up and running quickly with our 24/7 service and highly trained technicians. We diagnosis the problem correctly the first time, and if we cannot repair it on the spot, we can usually have the needed parts in hand the next day, to minimize your down time.


If your system is older and repairs are getting expensive, or the system is not energy efficient, we can provide an estimate for replacing it. We also provide a corresponding repair cost so you can make an informed decision. We can often get the system replaced in one business day saving you time, money, and the inconvenience of a prolonged shut down.
