Seasonal service & tune-ups
Get the furnace ready before winter and the AC ready before summer, so problems are caught early instead of on the coldest or hottest day.

What It Is
One Team for Both
Heating & Cooling
Your furnace and your air conditioner aren't two separate machines so much as the two halves of one comfort system — they often share the same air handler, ductwork, and thermostat. Trying to keep them running with two different companies means two sets of scheduling, two diagnoses, and finger-pointing when something's off. We handle both: seasonal service and tune-ups, repairs when something fails, and replacement or installation when a unit has reached the end of the line.
This is the ongoing, keep-it-running relationship — different from a one-time whole-system HVAC installation (which is the job when you're putting in an entire new system). Here, the focus is your existing furnace and AC: getting the most life out of them, fixing them when they act up, and giving you an honest call on repair versus replacement when the time comes. One team, both units, all year.

What We Handle
Everything Furnace
& AC, One Team
Whatever your heating or cooling needs — routine or urgent — it's the same trusted team. Here's what we cover for both units.
Repairs
When a furnace or AC acts up — no heat, no cool, odd noises or smells — we diagnose the fault and fix it, for both units.
AC replacement
When an air conditioner is beyond worthwhile repair, we replace it with a properly sized, efficient unit — see our AC replacement page.
Furnace replacement
When a furnace is unsafe or worn out, we replace it and haul the old one away — see our furnace replacement page for that job.
New installation
Putting in an entire system, or a home with no HVAC yet? That's a full whole-system install — see our HVAC installation page.
One team for both
Because we handle heating and cooling together, there's no juggling two companies and no finger-pointing when something's off.
Do You Need Us?
Signs Your Furnace
or AC Needs Attention
Heating and cooling problems rarely fix themselves. If you're noticing these, it's time for service — and we'll tell you honestly whether it's a repair or a replacement.
Not keeping up
A furnace that can't warm the house or an AC that can't cool it is a clear sign a unit needs service — before it fails completely.
Rising energy bills
Heating or cooling costs creeping up without a change in usage often means a unit is running inefficiently and needs attention.
Strange noises or smells
Banging, rattling, or unusual odors from the furnace or AC point to a problem worth diagnosing before it gets worse.
Frequent breakdowns
If you're calling for repairs again and again, an aging unit may be telling you it's cheaper to replace than to keep fixing.
An older system
Furnaces and AC units have a limited lifespan — once they're well into their teens, service keeps them safe and flags when to plan a replacement.
It's been a while since service
If the furnace or AC hasn't been checked in a season or two, a tune-up catches small issues before they leave you without heat or cool.
How We Work
How We Handle Your Furnace & AC
Whether it's a tune-up, a repair, or a replacement, the approach is the same: diagnose honestly, then do what's actually right for your home.
Inspect & diagnose
We check the unit — furnace or AC — find what's actually wrong or worn, and assess its age and condition so nothing's a guess.
Honest repair-vs-replace call
We tell you straight whether a repair makes sense or whether the unit's age and condition make replacement the smarter money — no upselling.
Service, repair, or replace
We do the work: a tune-up, a repair, or a properly sized replacement — for the furnace, the AC, or both.
Test & confirm
We run the system, confirm it's heating or cooling properly and safely, and make sure it's doing its job before we leave.
Keep it running
We let you know when the other unit is due for a seasonal check, so both your furnace and AC stay ahead of the next season.

Shah turned my experience around from a bad one to a good one in the very beginning. Aleksandra at the office answered and addressed all my questions and concerns very thoroughly. Jose who did the rodent proofing, answered all my questions and took his time going through the crawlspace and making sure he found and covered all potential access points for rodents into the crawlspace. He was very patient and thorough.

Denis, German,& Alexander were great. Very professional, thorough and customer oriented. I would recommend them for any attic, crawl space, HVAC, insulation, rodent & sub pump work. They were nice, hard working & non intrusive.

We had Samim come out to our house. He was so kind, fair, and professional, and put me at ease following an exorbitant price gouging experience. I highly recommend Attic Pros and if you can, ask for Samim. You will be happy with the quality of their work as well.

(800) 543-0382Both of your comfort units, across their whole life: seasonal service and tune-ups to keep them running, repairs when something fails, and replacement or installation when a unit has reached the end of the road. The idea is one team for both heating and cooling, so you're not coordinating two companies.
HVAC installation is the one-time project of designing and putting in an entire new system — the right page for new construction, a home with no HVAC, or a full system replacement. This page is the ongoing service relationship for your existing furnace and AC: maintaining, repairing, and replacing units as needed. Put simply: installation is the big build-out; furnace & AC services is keeping it all running, and swapping a unit when it's time.
Both. We diagnose and repair furnace and AC problems first — replacement isn't automatically the answer. If a unit is worth fixing, we fix it. We only recommend replacement when the age, condition, or repair cost makes it the better value, and we'll tell you honestly which situation you're in.
It comes down to the unit's age, the cost of the repair versus the value of the unit, and how often it's been breaking down. A newer unit with a one-off fault is usually worth repairing; an older one that keeps failing is often cheaper to replace than to keep patching. We give you the honest math so you can decide — and if it's a replacement, see our AC replacement and furnace replacement pages.
Yes — and it's simpler that way. Your furnace and AC usually share the same air handler, ductwork, and thermostat, so one team that knows the whole system avoids the finger-pointing you get when separate companies handle each half. We service and repair both.
The ideal rhythm is seasonal: have the furnace checked before winter and the AC before summer. A quick tune-up before you rely on each unit catches small issues early, so you're far less likely to lose heat on the coldest night or cooling on the hottest afternoon.
If you already know a single unit is the problem, you can go straight to the specifics: see our AC replacement page for a failing air conditioner, or our furnace replacement page for a worn-out furnace. If you're not sure whether it's worth replacing, start here and we'll diagnose it first.
Yes. If you're considering a different setup, a ductless mini-split heats and cools without ductwork and is great for homes without ducts or for specific rooms — see our ductless mini-split installation page. We'll help you weigh whether to service what you have, replace a unit, or move to a different system.
