The questions homeowners ask before they call.

It depends on what the work is, and any firm number before a diagnosis is a guess. What does not vary is how the price is set: you get a diagnosis and a fixed price in writing before any work begins.

That price holds unless we open something up, find a genuinely hidden problem the first look could not see, and you approve the change before we go further. You are never billed a surprise.

Yes. Diagnosis is skilled work with instruments, and free diagnosis is usually recovered somewhere less visible, most often by pricing the repair high or by finding a reason you need a new system.

You are told the fee before the visit, not after, and it covers a full diagnosis and a written finding you can take to anyone.

No. Quoting a replacement system is different from diagnosing a broken one. A replacement quote involves sizing your home and laying out options, and that is part of earning your business, so there is no charge for it. You get a written quote you can compare against anyone else's.

The diagnostic fee applies when something has failed and needs to be found and identified. That is the skilled instrument work that a free-diagnosis model quietly pays for by selling you something. The two are not the same visit.

It should not, and that is the point of quoting a fixed price before we start. The number you approve is the number you pay. The only exception is if we open something up and find a genuinely hidden second problem that the first diagnosis could not see, and in that case we stop, show you what we found, and give you a new price to approve before going any further.

What will never happen is a bill that is higher than the quote with no conversation. If the price changes, you hear about it and you approve it first, or the work stops.

It depends on how many urgent calls are already ahead of you, and in a heat wave or a hard freeze there can be a lot of them. What you get regardless is a real arrival window rather than a vague promise that someone will come by at some point, and a phone call if that window has to move.

Heating and cooling emergencies are treated as urgent, and if there is an infant, an elderly person, or someone with a medical condition in the house, say so when you call and it moves you up the order.

Heating and cooling emergencies are treated as urgent, and after-hours emergency service is available for them year-round. If there is an infant, an elderly person, or someone with a medical condition in the house, say so when you call and it moves you up the order.

If you smell gas or suspect carbon monoxide, that is not a service call, it is an emergency. Leave the house and call 911 and your gas utility first.

Normal hours are Monday to Friday, 7:00am to 6:00pm, and Saturday 8:00am to 2:00pm. Sundays are reserved for emergencies.

After-hours emergency service is available for heating and cooling emergencies.

Only when it is genuinely the better value for you, and when it is, we will show you why with the numbers rather than just asserting it. On a system near the end of its life, replacement often is the smart call, and we will lay it out honestly against the repair.

What we will not do is manufacture a reason to replace a system that has good years left, or use a tune-up as a staged excuse to condemn it. If a repair will serve you, we will tell you so, even though the repair is the smaller ticket.

There is no single rule, though a useful starting point is whether the repair would cost more than about half the price of replacing the system. After we diagnose it, we put the repair cost and the replacement cost side by side and walk through the factors that actually decide it: age, the kind of failure, the refrigerant, the repair history, and how well the system has performed.

Then we tell you plainly what we would do if it were our house and our money. You still make the decision, with both numbers in writing to think over or take elsewhere.

Yes, and we encourage it if you have any doubt. Because you paid for the diagnosis, what we found is yours to take to another company, in writing. A recommendation that cannot survive a second opinion was not a good recommendation, and we would rather you feel certain about the decision.

Our prices do not expire overnight either, so there is time to think it over or to compare. Confidence in the decision matters more to us than closing it today.

Yes. We diagnose, repair and maintain the common residential heating and cooling equipment regardless of the brand on the box. The fundamentals, refrigerant, combustion, airflow and electrical controls, are shared across manufacturers, and a good technician works across them.

Where brand matters is warranty and parts, and we will tell you if a repair is covered by a manufacturer warranty you already have, so you are not paying for a part the maker owes you.

Across the Oklahoma City metro and the Tulsa metro, the two largest population centers in the state, covering the core cities and the surrounding suburbs, from Edmond and Norman around Oklahoma City to Broken Arrow and Owasso around Tulsa.

If you are on the edge of either metro and unsure, ask, because we would rather tell you honestly than pretend a service area is bigger than it is.

The community list is the core of each metro, not every ZIP code. If your town is not named but you are clearly within the Oklahoma City or Tulsa area, there is a good chance we reach you.

The honest way to find out is to ask, and you will get a straight answer rather than a quiet trip charge for a long drive.
