Most calls for AC repair in Plano, TX, come from homes that went up between the 1970s and the 1990s, when Plano was one of the fastest growing places in Texas. Plenty of those houses are now on their second or third air conditioner, with ducts that may be original. Here is what is particular about cooling and heating a Plano home, and how a call to the free line gets you to a local company.
Dallas Air & Heating is a free referral line with no technicians of its own. Once you call (469) 649-7066, a recorded assistant asks whether you need cooling or heating help, then collects your name, the best callback number, your ZIP and what is going wrong. The call goes to an independent, locally owned HVAC company that works in Plano, which diagnoses the problem, prices the job and does the work.
Plano: the suburb that boomed first and then ran out of room
Plano's name comes from the Spanish word for flat, which fits the land. It counted only 3,695 residents in 1960 and 17,872 in 1970. Then it exploded: 72,331 people by 1980, 128,713 by 1990 as big corporate headquarters moved in, and 222,030 by 2000. Growth has slowed sharply since, to 285,494 in 2020 and an estimated 293,000 in 2025, because Plano is surrounded by other cities and has little undeveloped land left.
A city that grew that fast and then stopped has a lot of houses of the same age. Neighborhoods from the 1970s and 1980s in east and central Plano are well past their first system, and many homes from the 1990s building wave in west Plano are on their second. A careful technician looks at the whole setup, including ducts that may be as old as the house, rather than assuming the outdoor unit is the only thing that has aged.
A Plano house by decade: what usually needs a closer look
A general pattern only. Remodels and earlier replacements change everything, so let the technician confirm what is actually in your attic and side yard.
1960s and 1970s
Likely on a third system or later. Original metal or early flexible ducts may leak at the joints, and attic insulation is often thin by today's standards. Ask whether the ducts were tested before sizing anything new.
1980s
The biggest building decade. Many homes moved to a second system in the 2000s, and that system may now be 15 to 25 years old. Ask what refrigerant it uses and whether a repair still makes sense at that age.
1990s and later
Often larger homes with two systems. Original builder equipment has mostly been replaced once. Ask whether the indoor coil was replaced with the outdoor unit last time, since a mismatched pair can cause repeat problems.
Renting in Plano when the AC fails
According to the Census Bureau, only about 57 percent of Plano homes are lived in by their owners, so a large share of the people searching for AC repair here are renters. If that is you, the first call is to your landlord or property manager. Read the repair section of your lease, follow the method it asks for, and keep a dated written copy of what you reported and when.
Some landlords ask tenants to find a company and send the bill. If yours does, get that in writing too, then call the line. Either way, a few safe checks help: confirm the thermostat is on Cool and set below room temperature, replace the filter if it is caked with dust, and reset a tripped breaker once. Anything beyond that belongs to a technician.
Heat records and the 2021 freeze
Plano has seen both extremes. Its record high is 118 degrees, set in 1936, and its record low is 7 below zero, set in 1930. More recently, Winter Storm Uri drove the temperature at DFW Airport to 2 below zero on February 16, 2021, the coldest North Texas reading in 72 years, while ERCOT ordered rotating outages across the state grid. Heat pumps struggle in that kind of cold, and gas furnaces need electricity to run their fans and controls.
The lesson for a Plano home is simple: know how your house heats before the next hard freeze. If your furnace is gas, the gas company named on your bill handles leaks. If that company is Atmos Energy, which is headquartered in Dallas and runs a training center in Plano, its emergency number is 866-322-8667. If you ever smell gas, get everyone outdoors and make the 911 and gas company calls from there. If a carbon monoxide detector goes off, do the same: out of the house, then 911.
Oncor, your retail provider and the AC
Plano is in Oncor's delivery area, so two companies are involved in your power. Oncor owns the lines and meters and restores outages. The retail provider you chose sends the bill. Neither one services air conditioners. When the whole house goes dark, report it to Oncor. If outlets and lights have power while the AC sits silent, the fault is in the system or its breaker, so the call to make is to an HVAC company.
Because Plano homes get power through Oncor's lines, they can qualify for Oncor's Home Energy Efficiency program, which offers incentives for upgrades such as heating and cooling equipment and insulation. Homeowners and, with the owner's permission, renters can take part, and the work goes through approved service providers. If you are replacing a system, ask whether the job qualifies before you sign.
Questions to ask before a Plano replacement
- Will you pull the city permit? Plano's Building Inspections department issues building permits. Ask that the permit and inspection be listed on the quote.
- Did you do a load calculation? A Plano home with new windows, more insulation or an enclosed patio may need a different size than its old unit.
- Are the ducts part of the plan? In a 1970s or 1980s house, sealing or replacing ducts can matter as much as the new equipment.
- Are the indoor and outdoor parts matched? New refrigerants require matching components, so a new outdoor unit on an old coil is a question worth raising.
- What is your TDLR license number? Check it with the state before work starts.
Why Plano homeowners call the line
Older systems fail at awkward hours
A 20 year old compressor does not wait for business hours. The line answers around the clock and passes your call to an independent company that serves Plano.
Useful for owners and landlords
With so many rental homes in Plano, landlords who live elsewhere can call with the property's ZIP code and be put through to a local company. Tenants should go through their landlord first.
Free, with no markup from the line
Calling costs nothing. The company you are connected with quotes its own price, and any payment goes straight to that company, never to the line.
A clear way to check credentials
Before you sign for a repair or a new system, this site walks you through looking up the company's air conditioning license on the TDLR website.
Services Plano homes ask about most
AC repair covers the summer basics, from warm air to a frozen coil. In a city full of systems in the 15 to 25 year range, AC installation and replacement is the page to read before deciding whether an old unit is worth fixing. Gas furnaces and heat pumps both see use in Plano winters, so furnace and heating repair matters when the first cold front arrives, and offices and shops along the city's business corridors can turn to commercial HVAC.
AC Repair
Warm air from the vents, a unit that hums but will not start, ice on the lines or water in the ceiling. What a proper diagnosis covers in Dallas heat and what to ask before you approve a repair.
AC Installation and Replacement
When replacing beats repairing, why a load calculation matters more than the brand, and what a complete installation quote should list.
Furnace and Heating Repair
No heat on a cold North Texas morning, a furnace that short cycles or a heat pump stuck in defrost. Gas safety first, then what a technician checks.
Commercial HVAC
Rooftop units, offices, shops and restaurants. How commercial service differs from residential and what to ask a commercial HVAC contractor.

How this line works: Dallas Air & Heating is a free phone line, not an HVAC company. It answers your call and connects you with an independent local heating and air conditioning company, which inspects, quotes and does the work, and which you pay directly. The line holds no HVAC license and does not repair, install or schedule anything itself. Those companies may pay Dallas Air & Heating a referral fee. You never pay the line. How it works.
Check the license yourself. In Texas, air conditioning and refrigeration contractors are licensed by the Texas Department of Licensing and Regulation (TDLR), and the license number belongs on the company's quotes and invoices. Ask for it and look it up with the TDLR license search (opens in a new tab) before work starts. It is also fair to ask for a certificate of insurance.
