Air conditioners cool houses during heat waves, leaving inhabitants more comfortable and reducing hair frizz and grape Popsicle addictions. Coolify residences with today’s Groupon: for $49, you get an AC spring maintenance checkup from John C. Flood, serving the District, Montgomery County, Prince Georges County, and Northern Virginia seven days a week (up to a $99 value).

John C. Flood’s skilled service technicians deftly ready homes and cooling systems for warmer climes, taking air conditioners through a thorough check list to get them in shipshape condition. Daydream about upcoming summer months while chillbox wranglers check evaporators and operating pressures and ensure that motors are running properly. Possible leaks will be addressed, as will all air filters and thermostats. Meticulous mechanics will then inspect the AC’s belt and make necessary tension adjustments, then clean the condenser coil and condensate drain and lubricate the breeze unit’s moving parts for optimal motion and killer line-dancing skills.

Though not included in today’s Groupon, the John C. Flood fixer-upper emporium also tackles plumbing, heating, and electrical issues; repairs sewer and water mains; and is adept at bath remodels that do not include gaping holes in the floor.

Though John C. Flood sometimes features a discounted price online, this Groupon still offers the best deal available.
