Most likely causes
What this usually means
An old system bleeds money in three ways: it runs less efficiently every year, repair calls stack up, and utility rebates expire. Slide the inputs to see what 3 more years on your current unit actually costs you.
3-year cost of NOT replacing
A new high-efficiency replacement pays for a meaningful chunk of itself before it's even installed, just from rebates and avoided cost.
Estimates based on a 4-6% annual efficiency loss on systems past their design life, statistical repair frequency for 10+ year units, and current Dominion/Pepco rebate schedules for high-SEER replacements. Your actual numbers depend on your home, your usage, and current programs. We'll calculate your exact figures in your free in-home quote.
Real offers, no gimmicks, no fake discounts. Stackable manufacturer and utility rebates, special financing through our Home Depot and Lowe's partnership, and a free in-home quote with zero pressure.

In-home quote
Free Comfort Advisor visit. Written quote. No diagnostic fee. No high-pressure pitch.
Comfort Advisor inspects your current system, talks through your priorities, and leaves you with options and a clean written quote. Typical visit: 45 to 60 minutes.
Free in-home quote applies to system replacement scenarios. Standard residential properties within our service area. Existing customers may book follow-up consultations as needed.
Manufacturer rebates
Active rebates from Carrier, Rheem, and Ruud on qualifying system replacements. Stackable with utility programs.
Rebate amounts vary by brand, equipment tier, and current manufacturer programs. We pull the current rebate schedule for you at the quote and apply it directly to your price.
Manufacturer rebate programs are set by Carrier, Rheem, Ruud, and other brands and change without notice. Eligibility depends on equipment tier, AHRI matching, and program window. Final rebate confirmed at quote.
Utility rebates
Dominion Energy, Washington Gas, Pepco. We handle the paperwork so you get the rebate without the friction.
High-efficiency heat pumps and condensing furnaces typically qualify. Programs change quarterly. Your quote includes the current rebate calculated for your zip code.
Utility rebate eligibility depends on equipment efficiency, account status, and current program funding. We submit the paperwork on your behalf; final rebate paid directly by the utility per their timeline.
Fast quote
Send a photo of your old unit (the label on the outdoor cabinet) and we can start your quote before we even pull up.
Speeds the in-home visit. Tonnage, brand, serial-stamped age — we read it off the photo and pre-spec your replacement options so the visit is shorter and more useful.
Photo-quote is a pre-qualification step, not a final quote. Final pricing requires an in-home visit to confirm ductwork, electrical, and installation conditions.

Choice 01 — The default
What most McCarthy customers choose.

Variable-speed comfort that hums.

25 SEER2 / 12 HSPF2. App-controlled. Room-by-room temperature. Designer-grade indoor units that look like furniture. For homes that want premium comfort and the lowest possible energy bills.

Aggregated reviews across Google, Yelp, BBB, and Angi for our partner installer McCarthy Services.
"Our 19-year-old AC finally quit on the hottest weekend of the summer. They came out Monday morning, walked me through three replacement options at three price points, and had a new system installed by Thursday. No pressure, no upsell, fair price."
"Replaced our 18-year-old system with a Carrier heat pump. On time both days, cleaned up after themselves, walked us through every step. Bill is already 30% lower than last summer."
"Called three contractors for replacement quotes. They were the only ones who explained the financing through Home Depot clearly, broke down the rebates, and didn't try to push the most expensive unit. Easy decision."
"Quilt ductless install in our finished attic. Quiet, app-controlled, and the room finally stays cool in August. Installer named Marcus knew the product inside out."
"Fair, fast, and they showed up when they said they would. That's all I want from a contractor."
"Furnace died on the coldest night of January. They had a Comfort Advisor at our door the next day, financed a new high-efficiency unit through Lowe's at $0 down, installed the following week. Bill is lower, house is warmer, never have to worry about that old unit again."
Plain answers, no fluff. The questions that come up most often before booking a free in-home quote.
Text or call any time and our system sends an immediate confirmation. A real person follows up fast — usually within the hour during business hours, the next morning if you reach out overnight. In-home replacement estimates are typically scheduled within 24 to 48 hours.
A standard high-efficiency central system runs $7,500 to $14,000 installed for most homes. Heat pumps trend higher. Ductless mini-splits start around $4,500 per zone. Final cost depends on home size, ductwork condition, and equipment tier. Free in-home estimates available.
Yes. Heat pumps are increasingly the right call for Northern Virginia homes — efficient cooling in summer, and heat down to about 5°F in winter, with backup electric or gas for the coldest weeks. Carrier and Rheem are the most common installs.
Yes. Our install partner McCarthy Services holds active HVAC contractor licenses in all three jurisdictions: Virginia #2705142947A, Maryland HVAC .01-117642, and DC PC40000035. License numbers are also in the footer of this page.
Primary brands are Rheem and Ruud (workhorse reliability, 10-year warranties standard), Carrier (premium tier, best variable-speed technology), and Quilt (high-efficiency ductless for homes that want app-controlled room-by-room comfort).
New systems carry the manufacturer warranty — typically 10 years on parts — plus a 1-year labor warranty through our install partner McCarthy Services. Optional extended labor coverage is available with a maintenance plan.
Yes. We work with Home Depot and Lowe's financing programs as well as direct lenders. Plans include 0% APR promotional terms and longer extended financing. Pre-qualification takes a few minutes during your in-home estimate. No down payment required for qualified buyers.
Three simple tests. First — is the unit over 10 years old and starting to need repeated service calls? Replace. Second — are summer electric or winter heating bills climbing year over year? Replace. Third — rooms uneven, system runs constantly, never quite catches up? Replace. We come out, look at it, and give you an honest written quote.
Dominion Energy, Washington Gas, and Pepco offer ongoing efficiency rebates for high-SEER heat pumps and condensing furnaces. Local utility programs change quarterly. Your estimate will include current applicable rebates calculated for your zip code, and we handle the paperwork.
Mini-splits work best for additions without ductwork, finished basements, sunrooms, garages, or older homes where running new ducts is impractical. Modern systems like Quilt deliver up to 25 SEER2 efficiency with app-controlled room-by-room comfort.
Yes. We're an authorized installer for both Home Depot and Lowe's HVAC programs. That gives our customers access to retailer financing terms, manufacturer rebates, and the buying power of two national brands behind every install.
No. In-home replacement estimates are free, with no obligation. A Comfort Advisor comes out, assesses the system, discusses your priorities, and leaves you with a written quote. No high-pressure sales pitch.
