Right now, you are probably sitting on your porch, thinking you have plenty of time to get ready for summer. You do not.

The Black Hills are about to turn your living room into a convection oven. Most of you will wait until it is hot enough to literally slow-cook the family hamster before you even think about calling us. We know your type.

Do not wait until the heat index hits triple digits and we have to see your great-grandma roaming the house, braless. Give us a call at Rainier Mechanical. We might not look fancy, but we are a hell of a lot cooler than your living room is about to be.

Deadwood is currently a cozy 60 degrees, and I know exactly what you’re doing. You’ve already broken out the flip-flops and shorts like you’ve got the memory of a goldfish and forgot where we live. Enjoy the sun for the next five minutes, because the Black Hills are preparing to slap the taste out of your mouth with a snowstorm by the weekend.

We’d love to say we’ll be there to hold your hand when the shivering starts, but we’d much rather just fix the unit and judge your lack of preparation.

Give us a call before your furnace decides to "find itself" by quitting its job. We’re in Deadwood and ready to get your system running hotter than Uncle Ron’s DMs after he updates his profile picture to one with someone else's boat.

Everyone else is living their best cozy life: apple picking, wearing cardigans, making their personality 90% about loving fall.
Meanwhile, your furnace said "Live, Laugh, Love" and then immediately chose violence.

The vibes in your house are less "pumpkin patch photo op" and more "why can I see my breath indoors?" That burning smell isn't your fall-scented candles working overtime. That's your HVAC system literally cooking itself while you pretend everything is fine.

Listen, we love a good denial era, but unlike a basic white girl's fall outfit, your heating system can't actually run on Uggs and vibes alone.

We're in Deadwood and ready to fix your system faster than PSL season turns into Peppermint Mocha season. Give us a call.

Fall in South Dakota is drunk on power and has no idea what it's doing. One day you're sweating, the next day your ni***es could cut glass, and everything else has retreated so far north you need a search party.

Your furnace is ghosting you like a Tinder match who got what they wanted while you're wrapped in every blanket you own, looking like a sad burrito.

Listen, we know you thought you could tough it out. Very brave. Very stupid. But unless you plan on using your oven as a space heater while your family huddles around it like some depressing Norman Rockwell painting, it's time to give us a call. We'll get your heating system running hotter than your browser history.

Located in Deadwood, SD. Call us before you start burning furniture for warmth like some pioneer who made bad life choices.

Oh, you thought you knew temperature swings? Cute. The Black Hills said, "Hold my beer," and then proceeded to chug the whole dang brewery.

11AM: Hotter than a tweaker's pipe and climbing. Your AC unit is wheezing like a chain smoker running a marathon.

10PM: Colder than a witch's... well, you know.

Your poor thermostat is having a full-blown identity crisis, switching back and forth more than a politician during election season. And your HVAC system? It's questioning every life choice that led it to this godforsaken corner of South Dakota.

Give us a call. We'll fix your temp problems faster than a teenager can disappoint their parents.

Are you so dang hot that Satan just asked you for your phone number? Before you start a long-distance relationship with him, we've got a better solution!

Our vans are cruising the neighborhood like ice cream trucks for adults, except instead of popsicles, we're delivering sweet relief. While our competitors look like they've been using their own broken AC units as saunas after a 3-day bender, we're making your house feel like the North Pole.

Listen, we know white vans look sketchy as hell rolling up to your house, but we promise we're just here to murder the heat, not your faith in humanity. Our techs will treat your AC unit better than your ex treated you.

Give us a call! We're located in Deadwood, SD, and we'll have you chilling harder than a co**se in Boot Hill!

I know you all are used to seeing us ride around in that sweet diesel that makes you question your Prius purchase, but the white van is back! No, it most definitely wasn’t sitting around just collecting dust for two years. I…uhh…had to have a footprint gas pedal installed. So, if you see this cruising around, no we are not trying to lure people in with candy and puppies. We are not creeps, we just appreciate sketchy looking vans, and with inflation this high, puppies and candy aren’t all that affordable.

Wow, it has been a while since I posted. No, I didn’t die. HVAC/R guys don’t die, they just multiple. We are like cockroaches, gremlins, or your cousin Tammy who somehow has eight kids even though she lives in pajama pants and her personality is terrible! Where was I going with this? Oh yeah, the weather is heating up, so give us a call. We will make your house so cold that you will fart snowflakes.

Well it's that time of year for all those "New year, new me!" posts. Except you won't be seeing one of those from us. Yes, your clothes might be cooler than mine, and yes you might eat a little healthier, but guess what? When you break your furnace even more by trying to fix it by following a Craigslist video, guess who swoops in and saves the day? Yep, that would be us. Or when you once rewired an extension cord your dog chewed through and thought that made you an electrician, but then you burnt everything out on your control panel later, who comes over? Yep, us again. So this isn't a new year/new us post. It's a "We are still the same dudes that want to save you when you royally **** up post." Give us a call. We'll be there!
